Control of patient interface means fixation

FIELD: medicine.

SUBSTANCE: first version of the system contains a patient interface means to supply a gas stream to the patient. The interface means comprises a headband for securing to the patient and a mechanism for fixing force adjustment. The system includes a device for monitoring the degree of blood flow through the patient's blood vessel. The device contains a sensor and a control unit. The sensor detects the data on the blood flow through the blood vessel and is connected to the control unit to transfer the data to the control unit. The control unit is able to receive data from the sensor and to estimate the degree of blood flow based on the data mentioned. The control unit is able to provide a signal based on the blood flow in the blood vessel. The system comprises an adjusting mechanism controlling the force of patient interface means fixation by means of the headband, based on the signal provided by the detection device. In a second version of the system, the evaluation unit controls the audio signal generator to generate a warning signal if the degree of blood flow in the blood vessel or the degree of blood vessel occlusion passes a predetermined threshold. A warning signal indicates that the fixation force of the interface means is too strong. The force should be adapted by the adjusting mechanism. The method for prevention of red marks formation comprises the steps of interface means fixation to the patient by means of fixation force. The degree of blood flow through the patient's blood vessel is then assessed. Further, the fixation force is adjusted so that blood flow is present and that the blood flow exceeds a predetermined threshold.

EFFECT: creation of a system and method that ensures reduction of red marks, and increased comfort of wearing of the patient interface means.

SUBSTANCE: group of inventions refers to medicine. A method for providing a patient's interface adjustment feedback to an individual is implemented by a system for supplying a pressurised breathable gas flow to the individual's airway. That is combined with generating the breathable gas flow to be delivered into the patient's airway through the patient's contour and interface being in contact with the individual's face. The breathable gas flow is generated by a pressure generator integrated into the body. The patient's interface is sealed on the individual's face by sealing generated by a contact between the patient's interface and face. An output signal of a sensor functionally connected to the patient's interface, which transmits the patient's interface adjustment or position information is received. The user is informed by means of the user's interface built into the body on the patient's interface adjustment or position information transmitted by the output signal of the sensor. The user's information contains: (a) identifying the physical location, wherein the sealing contact between the patient's interface and the individual's face is not enough, (b) suggested adjustment for improving the sealing contact between the patient's interface and the individual's face, or (c) both identifying the location, and suggested adjustment.

SUBSTANCE: invention is intended for application in drug administration under pressure, e.g. in aerosol drug administration system. In one version, face mask includes at least partially deformed case with surface contacting patient's face, nose bridge zone made in the upper case part, lower bent section where part of case is bent for positioning over face, and two holes in eye area at different sides of nose bridge. When the mask is placed over patient's face, the holes can be positioned over patient's eyes. Case is shaped so as the lower bent part is at least partially creased when mask is placed over face, and eye holes can form gap remaining open between internal edge of the hole and face part below eyes to provide outlet for mask placed over face with at least partial crease of lower bent section.

EFFECT: facial masks in different implementation version reduce aerosol particle inertia in areas close to nose, thus reducing amount of aerosol drug precipitation in eye area in the result of inertial sedimentation impact, while aerosol drug flow in mask cavity is maintained at level required for efficient drug supply to respiratory system of patient.
