The inflatable bag 3 can be placed in outside simulated lung 4, simulated lung 4 by another air valve with it is inflatable
Airbag 3 connects, and is communicated with the gas circuit of inflatable bag 3 by the switch control simulated lung 4 of the air valve and separated with gas circuit.The air valve
During opening and when closing, the airway pressure corresponding to the gas of simulated lung incoming call same volume is different, so as to fulfill difference
Lung compliance.When simulated lung connects multiple inflatable bags by air valve, it is possible to achieve more lung compliance.
The aerating device 1 can be directly coupled on inflatable bag, realize aerification function.
The air valve 2 is individually connected with inflatable bag 1, realizes deflation function.
The device is made of single simulated lung 4 or more than one simulated lung 4 forms.
The simulated lung 4 and inflatable bag 3 are made of flexible material or elastic material.
A kind of application method for the device for being used to simulate variable lung compliance, aerating device 1 is by air valve 2 to inflatable
Airbag 3 is inflated, and the different corresponding volumes of the tolerance that inflatable bag 3 is charged into are also different, and the tolerance being charged into is more, inflatable gas
The volume of bag 3 is also bigger；When the volume change of inflatable bag 3 during 4 incoming call same volume tolerance of simulated lung, corresponding gas
Road pressure is different, and corresponding airway pressure is just during the bigger 4 incoming call same volume tolerance of simulated lung of the volume of inflatable bag 3
Bigger, the compliance of corresponding lung will decline.
The device of lung compliance provided by the invention fills an inflatable airbag in the inside of simulated lung, by inflatable
Airbag, air valve and aerating device composition outlet, gas handling system, simulated lung and the simulated lung air inlet pipe being connected on itself, pass through
Change the volume of inflatable airbag so as to change volume and the air pressure of simulated lung, just can easily realize that a variety of different lungs are complied with
Property, simple in structure without increasing other building blocks, manufacture cost is low.
