Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] refer to figure 1 and figure 2 , the device includes an inflatable device 1, an air valve 2, an inflatable air bag 3 and a simulated lung 4, the inflatable air bag 3 is arranged inside the simulated lung 4, and the air inlet of the inflatable air bag 3 passes through the air valve 2 and the inflatable device The trachea of ​​1 is usually connected by a single simulated lung 4 or more than one simulated lung 4 .

[0025] The inflatable air bag 3, the air valve 2 and the inflatable device 1 form an independent air outlet and air intake system, and the simulated lung and the simulated lung intake pipe connected to itself form a...

Abstract

The invention relates to the technical field of medical simulation instruments, in particular to a device and method used for simulating changeable lung compliance. The device comprises an inflator, an air valve, an inflatable air bag and a simulated lung. The inflatable air bag is arranged in the simulated lung, an air inlet of the inflatable air bag is communicated with an air pipe of the inflator through the air valve, and the inflatable air bag, the air valve and the inflator form an impendent air outlet and air inlet system. The simulated lung and a simulated lung air inlet pipe connected to the simulated lung form an impendent air outlet and air inlet system, and the volume of the inflatable air bag is changed to change the volume and air pressure of the simulated lung. According to the device, the inflatable air bag, the air valve and the inflator form one air outlet and air inlet system, the simulated lung and the simulated lung air inlet pipe connected to the simulated lung form the other impendent air outlet and air inlet system, the volume of the inflatable air bag is changed to change the volume and air pressure of the simulated lung, in this way, different degrees of lung compliance can be easily achieved without additionally arranging other components, and accordingly the device is simple in structure and low in manufacturing cost.

Description

[technical field] [0001] The invention relates to the technical field of medical simulation equipment, in particular to a device and method for simulating variable lung compliance. [Background technique] [0002] Lung compliance is the expandability of respiratory system tissue under airway pressure, which represents the effect of changes in airway pressure on lung volume. It is useful in practice as a measure of the relative stiffness of the lungs. The more rigid the lungs, the less compliant they are, and diseases that lead to fibrous accumulation in the lungs or edema of the alveolar spaces can make the lungs less compliant. The decrease in lung compliance increases with emphysema or with advancing age, possibly due to changes in elastin in both conditions. Reduced lung compliance can be seen in some lung diseases: restrictive lung disease, including various types of fibrosis, pleural fibrosis, etc.; pulmonary edema, congestion; respiratory distress syndrome, due to the...
