Wherein, positive pressure respirator can be invasive positive pressure respirator or woundless positive pressure respirator in the prior art, positive pressure The working principle of ventilator is to provide the positive pressure gas flow of certain pressure in inspiratory phase through air flue, to realize artificial ventilation and breathing The purpose of support.The working principle for the abdomen squash type air-breather 100 that the application is proposed is squeezed during human exhaled breath Human abdomen is pressed, helps sufficiently to exhale to realize Breathing Suppotion.Therefore according to the two-way Breathing Suppotion of the utility model embodiment Ventilator can form positive pressure respirator and provide air-breathing in inspiratory phase and support that the abdomen squash type air-breather 100 exhaling Gas phase is provided to exhale and be supported, to realize the two-way Breathing Suppotion to user's inspiratory phase, expiratory phase.

Furthermore, it is possible to export electronic signal when its air-breathing end or initial expiration by the interface of positive pressure respirator, use this Signal controls the working condition of abdomen squash type air-breather 100, i.e., with positive pressure respirator air-breathing end or initial electricity of exhaling Subsignal triggering abdomen squash type air-breather 100 is started to work (start squeeze abdomen), with positive pressure respirator end-tidal or The initial electronic signal of air-breathing terminates the work (terminate and squeeze abdomen) of abdomen squash type air-breather 100, thus realization pair User's expiratory phase provides Breathing Suppotion.

As a result, according to the two-way Breathing Suppotion ventilator of the utility model embodiment, positive pressure respirator and abdomen are squeezed Pressure type air-breather 100 is connected, so as to which abdomen squash type air-breather 100 and positive pressure respirator is same by controller Breathing Suppotion of the Shi Lianhe for the same user is treated, and thus can provide inspiratory phase to user simultaneously and expiratory phase is exhaled It inhales and supports, i.e., provided in air-breathing by positive pressure respirator and support, provide branch by abdomen squash type air-breather 100 in expiratory phase It holds, realizes the two-way Breathing Suppotion to user's inspiratory phase, expiratory phase.And then the effect of Breathing Suppotion can be greatly improved, more have Conducive to the ventilation supportive treatment of user.Specific application will be described in following content.

Three kinds of specific applications according to the utility model embodiment abdomen squash type air-breather are described below.

One, the exclusive use of abdomen squash type air-breather, can be used for respiratory failure user carry out Breathing Suppotion or Treatment when human assistance is ventilated.It is primarily adapted for use in the treatment of light moderate respiratory failure user, noninvasive positive pressure is exhaled in similar clinic The indication and application range of suction machine.

The abdomen squash type air-breather of the utility model embodiment and woundless positive pressure respirator in the prior art have Wound positive pressure respirator compares, and mainly has following difference:

1. working principle is entirely different, abdomen squash type air-breather be by upward abdomen, to move up diaphram crowded Pressure thoracic cavity helps user sufficiently to exhale to realize Breathing Suppotion；Positive pressure respirator is by being sent directly into positive pressure gas to intrapulmonary Stream realizes Breathing Suppotion.

2. working method is entirely different, abdomen squash type air-breather is by directly applying mechanical force or vibration to abdomen Mode work, positive pressure respirator be to intrapulmonary be sent into positive pressure gas flow mode carry out work.When work, abdomen squash type ventilation dress Setting must use or not be related to by mechanics device but gas circuit, and positive pressure respirator must then use air-channel system device but not It is related to mechanics device.

3. the respiratory phase supported is different, abdomen squash type air-breather is to provide support, positive pressure respirator to expiratory phase It is to provide support to inspiratory phase.

4. therapeutic efficiency is different, abdomen squash type air-breather is suitable for the treatment of mild user, and positive pressure respirator is suitable It shares in the treatment of middle severe user, the two both can be used alone, and can also be used in combination and complement one another.

5. degree that the device is complicated and operation complexity are different, abdomen squash type air-breather structure is relatively simple, operation compared with Simply, user is easy to grasp use；Structure is complicated for positive pressure respirator, operation is more complex, user is not easy to grasp and use.Abdomen squeezes Formula air-breather only needs power supply, does not need compressed gas source when working；Compressed gas source and oxygen are needed when positive pressure respirator works more Gas gas source.

6. safety and side effect are different, when abdomen squash type air-breather use, does not destroy negative pressure in thoracic cavity, to circulation The influence of function is little, will not cause ventilator associated lung injury and Ventilator Associated Pneumonia, and side effect is less；Positive pressure respiration Machine can cause ventilator associated lung injury and Ventilator Associated Pneumonia, and usually influence circulatory function, and side effect is more.Abdomen Squash type air-breather safety is higher, security risk is smaller, mortality event will not occur in use, and in contrast, positive pressure is exhaled Suction machine safety is lower, security risk is larger, the generation of mortality event is much (such as de- pipe) in use.

7. consumers' acceptable degree is different, artificial airway, not influence user normal without establishing for abdomen squash type air-breather It exchanges into diet with speaking, user's sense of discomfort is less, and user is easy to receive, and positive pressure respirator must be set up artificial airway, influences User normally exchanges into diet with speaking, and user's sense of discomfort is obvious, and user is not easily accepted by.

8. the difference of expense, the acquisition expenses and cost of use of abdomen squash type air-breather are lower, positive pressure respirator Acquisition expenses and cost of use it is higher.

Two, abdomen squash type air-breather can be individually used for the respiratory function rehabilitation of chronic obstructive pulmonary disease (COPD) user Treatment or respiratory function rehabilitation training.

Respiratory function rehabilitation or training are always an important link in COPD treatment, by clinical medicine circle Pay much attention to.But for a long time, only seldom several respiratory function rehabilitation training equipment are available in clinic and use, and such as contract Lip breathing respiratory exercise, skelps, respiration training (air-breathing training aids, expiration training aids) etc. for six minutes, respiratory function rehabilitation and The scarcity of training equipment is the awkward situation that COPD user's rehabilitation at this stage or training face.Abdomen squash type air-breather can be with Well solve this problem.

The abdomen squash type air-breather of the utility model by expiratory phase to user's abdomen carry out it is controllable, rule to Upper extruding artificially increases amplitude, the extruding thoracic cavity that diaphram moves up in expiratory phase, increases intrapulmonary expiratory gas volume, thus Achieve the purpose that increase ventilatory capacity and Breathing Suppotion.This artificial mode for passively increasing diaphram mobile range, can undoubtedly pierce Swash and increase the intensity and thickness of diaphram, and then the contraction and locomitivity for improving diaphragmatic fatigue, increasing diaphram, this is exactly COPD It to be solved the problems, such as or purpose to be achieved when the treatment of user's respiratory convalescence or training.Therefore, it is squeezed by the way that abdomen is used for a long time Formula air-breather is necessarily help to the treatment of COPD user's respiratory convalescence or training, to further improve the lung function of user.

Based on above-mentioned cognition and the unique working method of abdomen squash type air-breather, we are it can be found that abdomen squeezes Formula air-breather is the equipment that the respiratory convalescence of good COPD user a kind of is treated or trained, and ventilates and fills using abdomen squash type The level that treatment is conducive to improve or improve the treatment of COPD user's respiratory convalescence or training is set, improves the lung function of user, and make Good fortune is in numerous COPD users.

Three, abdomen squash type air-breather and positive pressure respirator are used in combination, and can be used for carrying out respiratory failure user Breathing Suppotion or artificial ventilation's treatment.It is primarily adapted for use in the treatment of middle Severe Respiratory Failure user, invasive positive pressure in similar clinic The indication and application range of ventilator.

The abdomen squash type air-breather of the utility model by expiratory phase to user's abdomen carry out it is controllable, rule to Upper extruding artificially increases amplitude, extruding thoracic cavity that diaphram is moved up in expiratory phase, increases intrapulmonary expiratory gas volume, that is, increase Add expiratory gas volume (expiration tidal volume), reduce intrapulmonary residual volume(RV), it is next when expiratory gas volume increases, intrapulmonary residual volume(RV) is reduced The inevitable increase proportional therewith of the inspiratory capacity (air-breathing tidal volume) of respiratory cycle increases ventilatory capacity and Breathing Suppotion to reach Purpose.In brief, abdomen squash type air-breather is to realize human assistance ventilation and breathing branch by the support to expiratory phase It holds.

Based on abdomen squash type air-breather and positive pressure respirator in working principle, structure, working method, Breathing Suppotion All various differences such as phase, working efficiency, side effect, the remarkable advantage of abdomen squash type air-breather are exactly that positive pressure is exhaled The obvious deficiency of suction machine, the remarkable advantage of positive pressure respirator are also exactly the deficiency of abdomen squash type air-breather, therefore abdomen Both squash type air-breather and positive pressure respirator can become other side and supplement well, supplement other side not with the advantage of a side Foot is based on above-mentioned consideration, abdomen squash type air-breather and positive pressure respirator can be combined simultaneously and be used for the same user's Breathing Suppotion treatment thus can provide the Breathing Suppotion of inspiratory phase and expiratory phase to user simultaneously, i.e., in air-breathing Shi Youzheng It presses ventilator to provide support, provide support by abdomen squash type air-breather in expiratory phase.When abdomen squash type air-breather and When positive pressure respirator use in conjunction, due to having the support of abdomen squash type air-breather offer, the expiration of user in expiratory phase Can be more abundant, exhalation tidal volume necessarily increases, this will necessarily reduce demand of the user to inspiratory phase Breathing Suppotion pressure To reduce the operating pressure of positive pressure respirator, that is to say, that when positive pressure respirator can be made to run under low operating pressures It can reach its clinical therapeutic efficacy run under higher operating pressure in the past.In other words, guaranteeing support curative effect phase of ventilating With in the case where, the application of abdomen squash type air-breather can reduce the operating pressure of positive pressure respirator, i.e. positive pressure respirator It can achieve same curative effect with lower operating pressure.With the reduction of positive pressure respirator operating pressure, then will necessarily mitigate The generation of ventilator-associated lung injury will necessarily also mitigate positive pressure respirator to the shadow of circulatory function, digestive function etc. simultaneously It rings, positive help will necessarily be brought to the clinical treatment of user in this way.

The electronic control part of current all positive pressure respirators is very mature and perfect, can connecing by positive pressure respirator Mouthful, electronic signal when exporting its air-breathing end or exhaling initial controls the work of abdomen squash type air-breather with this signal State is started to work with positive pressure respirator air-breathing end or the electronic signal triggering abdomen squash type air-breather for exhaling initial (starting to squeeze abdomen) terminates abdomen squash type air-breather with the initial electronic signal of positive pressure respirator end-tidal or air-breathing Work (terminate squeeze abdomen), provide Breathing Suppotion to user's expiratory phase to realize.This combination functionally, makes Abdomen squash type air-breather and positive pressure respirator melt as an organic whole, are more advantageous to the ventilation supportive treatment of user. Positive pressure respirator and abdomen squash type air-breather can will be melted as the respiratory support systems of an entirety, title in this way For two-way Breathing Suppotion ventilator.This two-way Breathing Suppotion ventilator overcomes positive pressure respirator and the ventilation of abdomen squash type The respective defect of device, the ventilating mode for foring a kind of completely new ventilation support mode — that is, two-way ventilation support are (referred to as double To ventilation), two-way ventilation provided by two-way Breathing Suppotion ventilator, to needing high platform pressure ventilation to support user (such as ARDS User) treatment it is especially significant, two-way ventilation can be substantially reduced the operating pressure of positive pressure respirator, to reduce Yin Gaoping The caused a series of side effects of platform pressure, such as stomach and intestine extravasated blood, hemorrhage of digestive tract, circulatory function be impacted, Ventilator Acquired lung Damage etc..
