2Gas cylinder, gas-liquid separator 22 is used for separation of C O
2In liquid, manually fine adjustment valve 23, gas-liquid separator 22 are CO
2The attached parts of gas cylinder 21 during work, are opened manual fine adjustment valve 23, and control device 20 is the numerical value of detected pressures switch 25, when numerical value during less than setting value, start electromagnetic valve 24, CO
2Gas will charge into constant voltage gas tank 26, and when reaching setting value, electromagnetic valve 24 cuts out, and constant voltage gas tank 26 will keep a constant pressure like this.
When charging into gas in the thoracic cavity, control device is opened electromagnetic valve 28, when pressure switch 29 arrives setting value, closes electromagnetic valve 28, and flow proportion valve 27 is used to control the speed of gas flow.
Negative pressure gas tank 35 will keep a constant negative pressure under the control of pressure switch, when pressure greater than when setting value, vacuum pump 38 is started working, electromagnetic valve 37 is opened, when pressure reached setting value, electromagnetic valve 37 cut out.
When extracting in the thoracic cavity gas, open manual fine adjustment valve 34 earlier, control device 20 is opened electromagnetic valve 32 then, when pressure switch 29 reaches setting value, close electromagnetic valve 32, flow proportion valve 33 is used to control the speed of gas flow, and gas-liquid separator 30, gas-liquid separator 31 are used for the liquid of divided gas flow.
The effect of inventing described control device 20 is operations of coordinating and controlling single unit system, makes the pressure of positive and negative pressure gas that gas cylinder produces and the requirement that flow reaches treatment.The effect of pressure switch 29,25,36 of the present invention is to monitor and the pressure of control positive and negative pressure gas, and it is controlled in the maximum positive/negative pressure scope that the human lung can bear.The effect of flow proportion valve 27,33 of the present invention is the sizes that monitor and control the positive and negative pressure gas flow, makes it can satisfy the requirement of treatment.
Coupling part, thoracic cavity, negative pressure aspirator etc. are identical with embodiment 1 among the embodiment 2, omit among the figure.
By the foregoing description 1, embodiment 2 and comparison diagram 2 and Fig. 3, the present invention and traditional respirator have completely different thinking as can be seen.The mode of tradition respirator only is to execute a malleation toward pulmonary, to reach the ventilation purpose.The present invention adopts a positive negative pressure generator, and from pulmonary's intubate, imposes on certain pressure, the extruding pulmonary fluid, and sucking-off pulmonary hydrops again according to the frequency of breathing, applies oxygen toward pulmonary simultaneously, improves oxygen content, thereby reaches the ventilation purpose.This system has more effectively solved adult respiratory distress syndrome patient's ventilation problem, has obvious improvement, special proposition patent application.
The above is specific embodiments of the invention only, is not in order to limiting patent claim of the present invention, and all other do not break away from the equivalence of being finished under the disclosed spirit and change or modify, and all should be included in the described patent claim.
