The scope of the invention

The invention relates to portable electronic physiological instrument, and more particularly to data ports and therapy for portable defibrillator.

Background of the invention

It is well known that the probability of survival after a heart attack depends on the speed with which it is treated. One of the most common and life-threatening consequences of a heart attack is the development of cardiac arrhythmia, such as ventricular fibrillation in which the heart is unable to pump enough blood. When developing this arrhythmia, it inevitably leads to severe brain damage and death if within a few minutes you cannot restore a normal heart rhythm.

The most effective method of treatment over the fibrillation is giving the victim a strong electric discharge. Electrical discharge often stops chaotic activity that is typical of arrhythmias,poisons were known and has been used successfully for many years. However, the size and cost of previous defibrillators in conjunction with the risk they pose if used improperly limited the use of defibrillators paramedical personnel emergency (SMSP) and other trained staff emergency.

Recently it was found that a greater number of victims of heart attacks can be saved if the person who is usually first to arrive on call emergency medical care, including firefighters, police, and even ordinary citizens (hereinafter collectively referred to as "the first respondents") were equipped with portable defibrillators. Due to the low qualification level of the first group of respondents, portable defibrillator provided by the first Respondent should be simple as possible. Reducing the complexity of the portable defibrillator ensures that even in stressful emergency situations, the first Respondent will be able to successfully connect the defibrillator to the patient and submit a defibrillation pulse. Therefore, the defibrillator, the first Respondent should be designed as far as possible accessible to the user.

An important characteristic that exists in many port the ECJ defibrillation, for further analysis. These data may include electrocardiogram (ECG) of the patient associated with the event data corresponding to the functions performed by a user of the defibrillator, and the voice or other data logged in the place where is emergency care. The preferred method of access to the stored data is then loaded through the dedicated data port located on the defibrillator. To download data cable connect a dedicated data port on the defibrillator and the communication port on the computer. Then the computer loads the data surrounding the defibrillation event, where they can be stored for later analysis.

Unfortunately, the inclusion of a specially designed port data to the portable defibrillator poses many problems, especially when the defibrillator is used by the first Respondent. Most defibrillators have therapeutic port through which the patient signals defibrillation. The set of electrodes is inserted into therapeutic port, and through the electrodes to the patient is pulse defibrillation. Although experienced users of portable defibrillators are extensive is castorena training, or may be prone to forget such training during the turmoil at the situation, emergency. Faced with two ports on the defibrillator, an inexperienced user can therefore easily confused ports and attempt to insert a set of electrodes to the data port. Alternatively, the user may attempt to insert the communication cable into therapeutic port. Therefore, the defibrillator, the first Respondent should not have two ports, because the user can easily confuse the port used for the pulse defibrillation to the patient, with the port used to transfer data to the computer.

In addition, defibrillators generate extremely high voltages when applying defibrillation pulse to the patient. Specially designed port data inevitably increases the amount of bare metal on the outer surface of the block, thus increasing the probability that a short circuit inside the defibrillator can reach the operator in contact with the data port.

So defibrillators with individual therapy port and data port require special shielding or additional circuitry to minimize the likelihood of accidental electric shock.

Finally, portable defibrillators asparagic pollutants. Therefore, portable defibrillators should be waterproof to protect the internal circuits from damage or internal short circuits. Defibrillator with plenty of ports is associated with high costs when designing due to the sealing plugs required to maintain water-resistance to more than one port.

The present invention is directed at overcoming the above and other disadvantages. More specifically, the present invention is directed to reducing the number of ports in a portable defibrillator, thereby increasing the level of water resistance, which reduces the possibility of destruction by the operator of the device and reduces the probability of errors of the first Respondent during situations of emergency.

The invention

In accordance with the present invention is a portable defibrillator with the common port of therapy/data. Portable defibrillator analyzes the electrocardiogram (ECG) of the patient and applies selective therapy on the basis of ECG and user input. The defibrillator includes a device for detecting the ECG of the patient, storing episodic data corresponding ECG, and EN is in the defibrillator for generating a defibrillation signal, which can be fed to the patient in accordance with the analyzed ECG. The communication interface is also provided in the defibrillator to transfer stored episodic data to the externally connected optional component. The common port of therapy/data connected to the communication interface and to therapy generator. The port allows the flow of therapeutic signals to the patient, the transfer of stored episodic data to the incremental component is connected to the port, and testing of the defibrillator.

In accordance with one aspect of the invention, the defibrillator determines whether connected to him, the patient, control the load or incremental component. The presence of the patient or control load initially is determined by measuring the impedance of the connected device. If the patient or the control load is not specified, the type is an extension component is determined by the transmission and reception of an identification signal or a user input. Various types of additives can be connected to the defibrillator, including the testing tool, modem, computer, printer, or other device for data storage and data presentation. Preferably, defibs balocny component.

In accordance with another aspect of the invention, the defibrillator may enter in one of several modes depending on whether you are connected to the defibrillator, the patient, the control load IDN extension component. When determining a patient, the defibrillator enters the normal mode, which analyzes the patient's ECG and applies an appropriate therapy to the patient. When the reference load, the defibrillator is in the type of work test user to provide verification of the operation of the defibrillator. If you define an extension component, the defibrillator is in the mode of communication data, in which data is transmitted from the defibrillator to the incremental component.

In accordance with another aspect of the invention, the protective circuit connecting the communication interface and the common port of therapy/data protects the communication interface from induced voltages and currents when is therapy of the patient. Limiting the voltage and current supplied to the communication interface during therapy the patient, prevents damage to the communications interface from damage during operation. Protective circuitry also protects the interface from damage by electrostatic discharge.

portable defibrillator. Perhaps most importantly, the common port of therapy/data simplifies the use of the defibrillator. Regardless of whether connected to the defibrillator, the patient, control the load or incremental component, the connection is made in the same port. By simplifying the operation of the defibrillator device can be used by the first Respondent, having little or even not undergone any formal training. The common port of therapy/data also reduces the total cost of the defibrillator. Therapeutic port/data port requires only one stub to ensure a watertight seal and eliminates the shielding or installation of circuits that are required to protect the operator from possible injuries electricity.

A detailed description of the preferred embodiments

In Fig.1 shows a portable defibrillator 10, made in accordance with the present invention and intended for use by the first responder during a medical emergency. For ease of use in field conditions, the defibrillator 10 is placed in a high-impact plastic housing 11, having a monolithic handle 14, which allows the user to easily transfer the defibrillator to the right place. When using a defibrillator to predpolene to the user. The control panel 16 includes a simplified interface to minimize the number of key input required for the operation of the defibrillator. The control panel has five buttons: button power supply 18, the analysis button 20, the button discharge 22 and two index buttons 24 and 26. The function of each button will be described in detail below. The defibrillator provides instructions or other information to the user with several different displays. A liquid crystal display (LCD) 28 displays instructions to the user to instruct the user to perform various settings, for example, "click analysis". In the case of a defibrillator built speaker 30 to enable the defibrillator to apply appropriate verbal command from the user. Also provided several LEDs 32 for indicating the status of the defibrillator, such as sufficiently charged energy-storage capacitor inside the defibrillator for submission of the defibrillation pulse to the patient.

Port therapy/data 12 is located close to the handle 14. Port therapy/data is used for connecting the defibrillator to the patient, to the incremental component or control strain. for mating with the connector port is used QUIK-COMBO, implemented by the Corporation Physio-Control Corporation of Redmond, Washington. Connector 38 QUIK-COMBO depicted separately with port therapy/data 12 of Fig.3. Connector 38 is equipped with a housing 46 having three electroconductive pins 48A, 48b and 48S, which are parallel to the trajectory on which the connector must enter the connection port of therapy/data 12. The connector should contain up to four pin electrical contacts. Each of the outer pins 48A and 48S can contain one male electrical contact, while the inner pin 48b is made for the reception of the two conductive pins. Each pin is made of electroconductive plastic to act as protection and prevent short circuits between the conductive pin contacts. The pins fit into the corresponding socket in port therapy/data 12. The housing 46 of the connector is also provided with a release latch 50, which is mainly parallel to the trajectory of the dock. The locking latch has a protrusion 52, which is latched at an additional tab in the port therapy/data to prevent accidental disconnection of the connector from the port. Release latch also serves as a key to prevent incorrect insertion of the connector into the material to be combined with the connector 38. Port therapy/data contains two therapeutic lines 64A and 64b and the two lines of data a and 82b, which are connected to electrical outlets in port therapy/data. When docking with the connector 38, each of the electrical outlets takes the corresponding male electrical contact in the inner or outer pins, assuming the existence of such a male electrical contact. Port therapy/data 12 is also equipped with two single seals 54 and 56, which are around the body of the port. Seals 54 and 56 form a groove 58 surrounding the port, which may be part of the plastic housing 11 of the defibrillator. The seals protect the defibrillator from the ingress of water, dirt or other contaminants.

The number of electrically conductive pins in the connector 33 varies depending on whether you are using a connector for connection to the defibrillator set of electrodes, cable ties or cable for testing. Returning to Fig. 1, when the connector is used (indicated by the connector 38A) with a set of electrodes, each of the two outer pins 48A and 48S contains male electrical contact. Each of pin electrical contacts connected to one set of electrodes 34 and output 36. To netsolitaire with the defibrillator 10, preferably the electrodes are the electrodes of the stimulation/defibrillation/ECG QUIK-COMBOTMimplemented by the Corporation Physio-Control Corporation. The electrodes QUIK-COMBO are disposable electrodes, which are superimposed on the patient by peeling the substrate to the electrodes for exposure of adhesive pads. To connect the electrodes to the defibrillator Resham 38A is inserted into the port therapy/data.

When connected to a patient, the defibrillator operates in the normal mode. The first Respondent places the electrodes on the patient inserts the connector QUIK-COMBO port therapy/data and includes a defibrillator by pressing the electric power supply 18. After identifying the patient using the techniques described below, the defibrillator is in normal mode. Following the instructions provided by the defibrillator, the first Respondent first clicks analysis 20. After clicking analyze the defibrillator analyzes the electrocardiogram (ECG) of the patient to determine whether to apply the patient therapy with defibrillation. If detected fibrillation, defibrillator shall notify the first Respondent as visual and auditory warning. Then the defibrillator automatically saraji charge, the first Respondent is instructed to press the button discharge 22 for feeding the defibrillation pulse to the patient through a set of electrode 34. Although other characteristics of the defibrillator available to the user, a complete discussion of the operation of the defibrillator is not necessary for understanding the present invention.

During therapy defibrillator 10 saves episodic data surrounding the situation of emergency. Episodic data usually include continuous ECG of the patient and the ECG result immediately before and after the defibrillation pulse delivered to the patient. The latest data is preferably formatted in accordance with the standard CODE SUMMARYTMadopted by the Corporation Physio-Control Corporation in their line of portable defibrillators, monitors, and Pacer. Episodic data may also include other data, including the time when they were filed with the defibrillation pulses to the patient, the energy of each pulse, the data of the impedance of the patient and other patient characteristics and systems necessary to restore therapy with defibrillation. In addition, anecdotal data may even contain a recording of what is happening, obtained using the microphone 40,the data who can register, limited only by the external sensors provided in fibrillatory, and the amount of memory available in the defibrillator 10. Compression techniques can be used for data compression of ECG and other data to increase to the maximum number of episodic data that can be stored.

Episodic data can later be downloaded from the defibrillator 10 in the extension component to analyze the results of a particular therapy in a patient, and to develop a database which can be studied the effectiveness of treatment in a large number of patients. To connect defibrillator 10 to the incremental component 44 of the cable 42 connects the defibrillator and extension component, as shown in Fig.2. Although the extension component is shown in Fig.2 in the form of a personal computer, you should take into account that the extension component may be any number of devices that would allow to store or analyze the data. For example, the extension component may be a printer for printing typewritten copies episodic data modem for transmitting episodic data to a remote computer or hard disk drive or drug therapy/data defibrillator, available cable QUIK-COMBO (indicated by the connector 38b), which contains three pin electrical contact. Internal pin 48b contains two pin electrical contact, and the outer pin 48A contains one male electrical contact. Pin 48S does not contain pin electrical contact in the connector of the communication cable. Three pin electrical contact in the connector 38b are connected with wires inside the cable 42. The other end of the cable 42 is connected to a connector (not shown) that is selected as required for interfacing with the extension component.

After connecting to the incremental component defibrillator recognizes the extension component and works in data transfer mode. In the data transfer mode data can be loaded in the extension component for printing, storage or analysis. Data can also swap in a defibrillator for the management of data, run tests defibrillator or software changes within the defibrillator.

Most modern defibrillators is also equipped with a test mode so that the operation of the defibrillator can easily be tested by the user. Daya testing of the defibrillator control the load which is to control the load to confirm the correct operation of the device. To connect the defibrillator to the test load is provided a control cable having a connector 38 QUIK-COMBO with four pin electrical contacts. Whip the electrical contacts in each of the outer pins 48A and 48b are connected with the control 50 Ohm load. Two pin electrical contact in the inner pin 48b are closed together. As additionally discussed in detail below, the detection control loads connected to the defibrillator, the defibrillator automatically included in the operation mode operational tests.

You should take into account that using a common port of therapy/data greatly simplifies the operation of the defibrillator. In responding to situations of emergency, the first responder will immediately recognize where to connect the set of electrodes to the defibrillator. No confusion due to the multiple ports on the defibrillator. Further, since the connectors used to connect the set of electrodes, a communication cable or control cable have essentially the same shape, the first Respondent can be easily trained to use a defibrillator.

For mounting the common port of therapy/data ensuring defibrillator. Fig. 4 is a block diagram of the hardware inside of the defibrillator 10. At the heart defibrillator is a microprocessor 60. Although shown with only one microprocessor, you should take into account that the dual microprocessors are installed in the defibrillator to provide redundancy and increase the processing capability of the microprocessor 60 is connected to the panel 16 by conduit 62. Therefore, the microprocessor can receive commands given to the first Respondent by using the buttons 18, 20, 22, 24 and 26 on the control panel. Voice data is perceived by the microphone 40 can also be converted into digital form and stored using methods known in this field. Instructions or visual commands to the user, the microprocessor can transmit on the data channel 62 corresponding data to activate the LCD display 28, the LEDs 32 or give voice commands through the speaker 30.

During normal operation, the microprocessor is responsible for analyzing the patient's ECG to determine is detected whether the rhythm you want to use defibrillation, and if so, charge the energy-storage capacitor for supplying fibrillatory through a common port of therapy/data. Two therapeutic lines 64A and 64b is connected to a port of therapy/data 12 for the distribution of the ECG signal within the defibrillator. Line 64b is the return line, while the line 64A is connected to the switch 66 discharge protection circuit 68 of the transition mode.

To manipulate the analog ECG signal within the defibrillator signal must be converted into digital form. Protective circuitry 68 of the transition mode, the preamplifier 70, and an analog-to-digital Converter 72 is connected between line 64A and a microprocessor for converting the ECG in digital form. Protective transitional regime ensures that the preamplifier will not be damaged when the patient serves defibrillation pulses for therapeutic lines 64A and 64b. The pre-amplifier 70 amplifies the ECG signal and provides it to an analog-to-digital Converter 72, where it is converted into digital form. After the adoption of the ECG signal it is analyzed by the microprocessor and stored as part of the episodic data for subsequent search. Although various media, such as computer tape, can be used to store episodic data, in the actual implementation of the invention ECG and other EPI the disorder 74 is a nonvolatile memory, so the data will be stored even if power to the defibrillator later will be turned off during transport.

If during the analysis of the ECG reveals the rhythm you want to use defibrillation, the microprocessor energizes the energy-storage capacitor C1 in anticipation of the filing of the defibrillation pulse to the patient. Charging a capacitor corresponding commands are issued in the high voltage circuit 76 charger disposed between the energy-storage capacitor and a portable battery power source 78. The voltage on the plates of the capacitor is measured in highway 79, which is connected to an analog-to-digital Converter 72. When the voltage reaches the desired level, the led in the button discharge 22 illuminates to indicate the first Respondent that the defibrillator is ready for filing discharge defibrillation to the patient. If the first Respondent clicks discharge, indicating that it should submit the discharge, the microprocessor closes the switch 66 of the discharge. Closure of switch 66 connects the discharge energy-storage capacitor C1 with the patient for therapeutic lines 64A and 64b, feeding the pulse defibrillation with hope for the termination of arrhythmia in the patient. The Indus is the pulse of the patient. If the defibrillation pulse may not terminate the arrhythmia in a patient, the process of charging and discharging of the energy-storage capacitor is repeated.

Upon completion of therapy the patient storage device 74 includes episodic data, which correspond to the applied therapy. As discussed above, episodic data can include ECG data, the data CODE SUMMARY, voice data and other information. To enable analysis of episodic data subsequent persons providing medical assistance, the data must be loaded from the defibrillator 10. To load data defibrillator is connected to the extension component, as shown in Fig.2. When the connection is completed, the microprocessor can transmit data to the incremental component via the communication interface 80. As shown in Fig.4, the communication interface is connected to the port therapy/data 12 by a pair of data lines a and 82b.

Fig. 5 is a diagram of the communication interface 80 that is used to connect the microprocessor 60 to the port therapy/data 12. Parallel data are provided from the microprocessor through the conduit 62 to a universal asynchronous receiver/transmitter (UART) 84. UART computers is 88 RS-232 transmission line TXD. Driver RS-232 increases the voltage level of the data signal for transmission over the cable 42 to the extension component. Driver RS-232 also lowers the voltage level of the received signals and provides the received data in UART receiving line RXD.

The driver 86 RS-232 is connected to the port therapy/12 through the data latches level 87a and 87b and the orifice 88. The clamper 87a includes a resistor R1 in series with the data line a, a pair of stabilizer diodes D1 and D2 connected cathode to cathode between the data line a and ground, and a capacitor C2, connected between the data line a and earth. The purpose of the clamper is to limit the voltage supplied to the driver RS-232. Although the defibrillation pulse is supplied by therapeutic lines 64A and 64b, and not on the data lines a and 82b, the proximity of therapeutic lines to the data lines, where the lines pass through the port therapy/data, which may cause the voltage pulse induced in the data lines. The clamper 87a prevents damage to driver RS-232 induced pulse voltage in the data line. The clamper also protects the driver RS-232 from electrostatic discharge (ESD). The clamper 87b has a design similar to the clamper 87a, with resistentie driver RS-232 ESR and induced voltage pulse in line receive data. As the transmission line, and the line data reception also pass through the orifice 88 ferrite puck. The choke restricts the amount of electromagnetic interference (EMI) generated during the transmission of signals by cable 42 which communicates with the port therapy/data.

When the operation mode data connection therapeutic line 64b is used as the circuit through the ground. Three-part interface (TXD, RXD and return) between the defibrillator and the additive component sufficient to ensure speed serial data transmission, reaching or exceeding 115 kilobaud. Specialists in this field will understand that due to the lack of dedicated lines confirm the communication interface, the confirmation communication between the defibrillator and the extension component must be performed in the software.

Returning to Fig. 4, the defibrillator is also provided with a circuit for measuring the impedance of the lines 64A and 64b under full voltage. Several different methods have been adopted to measure the impedance of the patient and the electrodes attached to the patient. In the actual implementation of the invention is the impedance of the generator 69 for generating a high-frequency alternating current signal. High and 64A. Using techniques that are known in this field, the impedance of therapeutic lines under full voltage is determined by the amplitude of the corresponding received signal AC, which are filtered from the ECG of the patient. The timer 67 is also provided in the defibrillator for providing a precise time base for the microprocessor 60.

To determine whether to work in normal mode, the communication mode or data mode control, the defibrillator should be able to determine whether you are connected to port therapy/patient data, incremental component go of the control load. The preferred software routine 100 to identify the identity element connected to the port therapy/data shown in Fig.6.

As shown in Fig.6, immediately after turning on the defibrillator in the network is the test of decision block 102 to determine if pressed was right index finger button 26 when turning on the defibrillator. If you clicked the right-pointing button when turning on the defibrillator, in block 104, the procedure assumes that the printer is connected to port therapy/data starts transmitting stored episodic format data for printing is input and data from a user, because some widely available printers do not provide output that can be used to identify the printer. However, the definition connected to the defibrillator, other devices or the patient, is performed automatically, as discussed below.

If the right index finger button was not pressed by the first Respondent for inclusion in the network, block 106 produces impedance measurement lines 64A and 64b under full voltage. The impedance is measured by applying a high frequency alternating current signal from the impedance of the generator 69. In decision block 108 and a test of the measured impedance. If the measured impedance is within the range 30-300 Ohm, the procedure continues to decision block 110. If the measured impedance falls in the range 30-300 Ohm, the procedure continues at block 118. The range 30-300 Ohm pre-selected to cover the expected range of impedance of the patient.

In decision block 110 test is performed to determine whether the impedance therapeutic line of 50 Ohms. If the impedance of therapeutic line is not equal to 50 Ohms, the procedure continues at block 112. In block 112, the defibrillator is in normal mode. That is, the detected impedance Terada to identify ECG of the patient in therapeutic lines. If the ECG is detected, analyzed and begin appropriate treatment.

If the impedance of therapeutic line is 50 Ohms, in decision block 110 test is performed to determine the user or defibrillator tries to enter the control mode of the user. To indicate that the defibrillator is ready to enter the control mode of the user connector control cable equipped with data lines a and 82b, shorted together. Therefore, in decision block 114 test is performed to determine shorted together the data line by the transmission signal line TXD and attempts to receive a signal on the RXD line. If the data line short-circuited, in block 116, the defibrillator is in the control mode of the user. If the data line is not shorted, in block 112 the defibrillator enters the normal mode, since the detected impedance is within the range, showing that the patient can be connected to the defibrillator. You should take into account that other techniques can also be used to indicate that the defibrillator is ready to enter the mode of the user's control, including pressing the corresponding sequences of buttons on the control panel of the defibrillator.

Returning to block the principles of the cheer continues at block 118. In block 118, the request is transmitted to the defibrillator on the data lines a and 82b. The request may take various forms, but is intended to provoke a reaction confirmation communication from the complementary component connected to the defibrillator through the port of therapy/data. In decision block 120 test is performed to determine if the response to the request. If a response is received, the decision block 122 test is performed to determine whether the answer is a special password. If the reply contains the password in block 128 the defibrillator is in production control mode. Production control mode is used by the manufacturer after Assembly defibrillator go during subsequent maintenance. In production test mode, data can be transferred between test equipment and a defibrillator for holding defibrillator through a set of tests. During tests, you can alternate the operation of the defibrillator in the normal operation mode and the operation mode data connection for full scan defibrillator.

If the answer of decision block 122 does not contain the password, the procedure continues at block 124. In block 124 type extension component, poseiden is destined to above, the extension component may be a computer or modem to allow transmission of episodic data to a remote computer. After identifying the attached extension component defibrillator is in the communication mode data in block 126. Mode data connection episodic data, control data or other data is transmitted to and received from an extension component.

Returning to the decision block 120, if no response is received within the corresponding time interval, the procedure continues to decision block 130. In decision block 130 examines the amount of time that the defibrillator is expected to identify the patient, incremental, component or control of the load. If the connection to the defibrillator has not been determined within a pre-selected period of interruption, the defibrillator will cease attempts to define the connection and automatically switches off. Auto shut off saves battery power in the event of an unforeseen turn on the defibrillator. If the period of interruption is not ended, the procedure returns to block 106, which is another dimension of impedance therapeutic line. Thus, the procedure is whether the reference load for the duration of the period of interruption.

You should take into account that the use of a single port for data communication and for therapy of the patient, provides several manufacturing advantages over the defibrillator with the ports allocated to each function. The only port reduces the cost of the defibrillator by facilitating waterproofing casing defibrillator. The only port also minimizes the number of connections between the internal circuit and the outer shell defibrillator, lightening protection from discharges occurring in the outer connectors.

Although the preferred embodiment of the invention has been illustrated and described, it should take into account that there may be various changes without departing from the spirit and scope of the claims of the invention. For example, although it is anticipated that the connector 38 of the usual form is used for connection of a set of electrodes, communication cable and control cable to the port therapy/data should be taken into account that the connectors of the other forms can be used for connecting each element with a defibrillator. However, the connector of the usual form simplifies the use of the first Respondent.

You must also take into account that harassers to increase the data rate of communication for the provision of leased lines confirm communication. The increase in the number of lines of data will require the reconstruction of the communication interface 80 to provide an appropriate interface between the microprocessor and the additive component. Connector 38 should also be increased to include additional amounts pin electrical contacts. The number of data lines can also be reduced to a single data line and the return line. However, reducing the number of lines of data will reduce the data rate of the connection.

Specialists in this field will also understand that although the overall port therapy/data was revealed in the context of a portable defibrillator 10, the common port of therapy/data may be included in other portable or reportative medical devices. For example, the common port of therapy/data may be included in portable electrostimulator, which is designed for analyzing the patient's ECG and therapy electrical stimulation. The design of the common port of therapy/data has a wide scope in any portable or reportative medical device that would benefit from reducing the number of external ports on the device. Therefore, within the claims attached formula sabrettes.
