The device of existing analog variable lung compliance not only complex structure, volume is large, cost is high, and the quantity that can realize different lung compliance is also limited, the quantity often realizing the compliance of different lungs is more, its structure composition is more complicated, for above-mentioned problems, this utility model designs a kind of device for analog variable lung compliance, and this device is except simple and reasonable, beyond volume is little, its manufacturing cost is also lower.
To achieve these goals, design a kind of device of the lung compliance for analog variable, comprise aerating device 1, air valve 2, inflatable bag 3 and test lung 4, it is inner that inflatable bag 3 is arranged at test lung 4, the air inlet of inflatable bag 3 is communicated with the trachea of aerating device 1 by air valve 2, inflatable bag 3, form one between air valve 2 and aerating device 1 three independently to give vent to anger, gas handling system, test lung forms one from test lung air inlet pipe with it and independently gives vent to anger with being connected to, gas handling system, by changing the volume of inflatable airbag 3 thus changing the volume of test lung 4 and air pressure.
Described device also comprises elastic compression device 5, the upper and lower two parts of elastic compression device 5 can move in the opposite direction each other under the pressure effect of test lung 4, and when test lung 4 is in exhaust phase, the device of two parts up and down of elastic compression device 5 can to close to each other thus force air to be discharged from test lung 4 under the elastic pressure at self.
Described inflatable bag 3 can be placed on that test lung 4 is outside, and test lung 4 is connected with inflatable bag 3 by another one air valve, to be communicated to cut off with gas circuit by the on-off control test lung 4 of this air valve with the gas circuit of inflatable bag 3.When this air valve is opened and when closing, the airway pressure corresponding to gas of test lung incoming call same volume is different, thus realizes different lung compliance.When test lung connects multiple inflatable bag by air valve, more lung compliance can be realized.
Described aerating device 1 can directly be connected on inflatable bag, realizes aerification function.
Described air valve 2 is connected with inflatable bag 1 separately, realizes venting function.
Described device is made up of single test lung 4 or more than one test lung 4 forms.
Described test lung 4 and inflatable bag 3 adopt flexible material or elastomeric material to make.
The device of the lung compliance that this utility model provides fills an inflatable airbag in the inside of test lung, by inflatable bag, air valve and aerating device composition give vent to anger, gas handling system, test lung and the test lung air inlet pipe be connected to from it, by changing the volume of inflatable airbag thus changing the volume of test lung and air pressure, just can realize multiple different lung compliance easily, without the need to increasing other building blocks, structure is simple, low cost of manufacture.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
With reference to figure 1 and Fig. 2, this device comprises aerating device 1, air valve 2, inflatable bag 3 and test lung 4, it is inner that inflatable bag 3 is arranged at test lung 4, the air inlet of inflatable bag 3 is communicated with the trachea of aerating device 1 by air valve 2, is generally made up of single test lung 4 or more than one test lung 4 forms.
Inflatable bag 3, form one and independently give vent to anger, gas handling system between air valve 2 and aerating device 1 three, test lung forms one from test lung air inlet pipe with it and independently gives vent to anger, gas handling system with being connected to.Aerating device 1 inflates to inflatable bag 3 by air valve 2, and inflatable bag 3 is also different by the different corresponding volume of tolerance be charged into, and the tolerance be charged into is more, and the volume of inflatable bag 3 is also larger.When the change in volume of inflatable bag 3 during test lung 4 incoming call same volume tolerance, corresponding airway pressure is different.Airway pressure corresponding during the volume larger test lung 4 incoming call same volume tolerance of inflatable bag 3 is larger, and the compliance of corresponding lung will decline, Fig. 3 to Fig. 6 for be filled with different volumes in inflatable bag tolerance corresponding to lung compliance.
When test lung 4 air-breathing expands, elastic compression device about 5 two parts device can move in the opposite direction each other under the pressure effect of test lung 4, when test lung 4 is in exhaust phase, the device of two parts up and down of elastic compression device 5 can to close to each other thus force air to be discharged from test lung 4 under the elastic pressure at self, wherein elastic compression device 5 is prior art, so do not provide detailed structure chart in figure.
Inflatable airbag 3 can also be placed on that test lung 4 is outside, and test lung 4 is connected with inflatable bag 3 by another one air valve, to be communicated to cut off with gas circuit by the on-off control test lung 4 of this air valve with the gas circuit of inflatable bag 3.When this air valve is opened and when closing, the airway pressure corresponding to gas of test lung 4 incoming call same volume is different, thus realizes different lung compliance.When test lung 4 connects multiple inflatable bag 3 by air valve, more lung compliance can be realized.Aerating device 1 can directly be connected in inflatable airbag 3, realizes aerification function.Air valve is connected with inflatable airbag 3 separately, realizes venting function.
