DETAILED DESCRIPTION

In Fig.1 schematically shows a device for facilitating expectoration in accordance with the embodiment of the invention.

The device 10 is used to facilitate expectoration on the basis of the oscillating pressure. The device 10 includes a block 11 of the control oscillation unit 12 for excitation of oscillations of the pulmonary system to cause periodic oscillating air flow in the pulmonary system, and the valve 13 controlled by the control block 11, this valve to be opened or closed to respectively connect the pulmonary system with the external environment through the mouth or isolation of the pulmonary system from the external environment.

The oscillation unit 12 may be combined with the control block 11, and is included in the device 10. For example, oscillatory BC is 12 is a block oscillating air pressure. Oscillating air pressure provided by the oscillation unit 12, is passed into the pulmonary system through the mouth for the excitation of oscillations of the Airways in the lung system.

Alternatively, the oscillation unit 12 may be separate from device 10 and is not integrated with the control block 11. For example, the oscillation unit 12 is a mechanical oscillation of the pressure unit. Mechanical oscillating pressure is passed into the pulmonary system through the chest and muscles, like, for example, high-frequency chest wall oscillation (HFCWO).

The oscillation unit 12 generates an oscillating pressure (denoted as OP in Fig.1) for the excitation of oscillations of the Airways in the lung system, and an oscillating pressure causes periodic oscillating air flow in the air path of the pulmonary system. Periodic oscillating air stream contains oscillating exhaled air flow and oscillating the inhaled air stream.

The control block 11 contains the first key unit 111 to determine whether completed breath pulmonary system to control the valve that must be closed to isolate the pulmonary system from the external environment, the second guide block 112 to determine whether the internal pressure of the air (labeled IAP in Fig.1) in agonoy system above, than a predetermined pressure threshold, and block 113 detection to detect the start oscillating exhaled air flow (indicated as OEA in Fig.1) to control valve 13 to be opened to start coughing.

The valve 13 may be combined with unit 11 controls to open or close the control effect of the control block 11. If the control valve 13 sets its closure for closing signal (denoted as CS in Fig.1) from the first key unit 111, the pulmonary system is isolated from the external environment, and the external air can be inhaled into the pulmonary system; if the control valve 13 sets his opening signal opening (denoted as OS in Fig.1) from block 113 detection, mucus and air (identified as A&M of Fig.1) in the air ways pulmonary system can vygashovatsa/fizzle out into the external environment, and the external air (indicated as A in Fig.1) can be inhaled into the Airways in the lung system.

When the internal air pressure in the pulmonary system is higher than a predetermined threshold pressure, the pulmonary system is ready to cough; if the block 113 detection detects the start oscillating the exhaled air flow, the control valve 13 sets its opening; if the valve 13 is opened, the pulmonary system is the beginning of the onset cough, when this oscillating exhaled air flow begins in accordance with a periodic oscillating air flow. A predefined pressure threshold can be set by the user, and a predetermined pressure threshold may be different for different people.

The first key unit 111 may be designed to determine, finished inhalation pulmonary system, when the speed of the inhaled air (denoted as VIA in Fig.1) in the pulmonary system is lower than a predefined speed threshold. Oscillating the exhaled air flow coincides with the exhaled air flow from the cough, at least at the beginning of the cough. At the beginning of the cough cough causes the maximum exhaled air flow in the air path of the pulmonary system. A predefined speed threshold can be set by the manufacturer of the device 10 or by the user, and the threshold speed may be zero or any other value near zero.

The inhaled air stream may contain respirable air flow caused only by the breath of the pulmonary system. Alternatively, the inhaled air stream may contain respirable air flow caused by inhalation pulmonary system, and oscillating the inhaled air flow caused astilleros the m pressure.

The first key unit 111 may include a sensor for the speed of the inhaled air in the air path of the pulmonary system, and the second guide unit may include a sensor for receiving the inner air pressure of the pulmonary system. Alternatively, the sensor of the first key unit 111 may be combined with the sensor of the second guide block 112.

In Fig.2 is a diagram to illustrate the correlation between the rate of the exhaled air flow from coughing and time. At the beginning of the cough, for example, at the time of 0.03 seconds, the velocity of the exhaled air flow is almost equal to 10 l/s (liter/second).

In Fig.3 shows a waveform for illustrating the correlation between speed oscillating air flow and time. Oscillating pressure causes periodic oscillating air flow in the air path of the pulmonary system, and oscillating the exhaled air flow oscillating air flow and oscillating inhaled air flow oscillating air flow are changed periodically. In the first of 0.05 with oscillating pressure causes the oscillating exhaled air flow (indicated as OEA in Fig.3) in the air paths of the pulmonary system, and in the following 0,03 with oscillating pressure causes the oscillating inhaled air flow (on the marked as OIA in Fig.3) in the air paths of the pulmonary system. The period of the periodic oscillating air flow may be 0.1 s, 0.2 s, 0.3 s, etc.

In the embodiment of the invention: first, the internal air pressure of the pulmonary system is greater than a predetermined threshold pressure, and pulmonary system is ready to cough; secondly, in the periodic oscillating air stream begins oscillating exhaled air flow; third, the valve 13 is opened; fourth, pulmonary system starts to cough and causes the maximum exhaled air flow in the air path of the pulmonary system at the beginning of the cough, for example at the time of 0.03 s, and at the same time in a periodic oscillating air stream begins oscillating exhaled air flow.

In Fig.4 shows schematically the mechanical excitation of oscillations in the pressure (labeled MOP) applied to the pulmonary system, and the air pressure (denoted as AP) in the pulmonary system register through the mouth in accordance with the example of the invention.

In Fig.5 schematically depicts an oscillating air pressure (labeled AOP), served in the pulmonary system through the mouth, and the air pressure (AP) in the pulmonary system register through the mouth in accordance with another embodiment of the invention.

In Fig.6 presents a flowchart of the sequence of operations for the zone of the possible ways of promoting expectoration in accordance with the embodiment of the invention. The method serves to facilitate expectoration on the basis of oscillating pressure and oscillating pressure causes periodic oscillating air flow in the air path of the pulmonary system.

The method further includes a step of forming 61 scilliroside, to initiate the oscillation of the pulmonary system to call periodic oscillating air flow in the air path of the pulmonary system.

When the internal air pressure of the pulmonary system is higher than a predetermined threshold pressure, the pulmonary system is ready to cough; if periodic oscillating air stream begins oscillating exhaled air flow, the control valve 13 sets its opening; if the valve 13 is open, the pulmonary system begins to cough, while oscillating the exhaled air flow begins in accordance with a periodic oscillating air flow.
