An airway device for simulating a lung breath demonstration

By designing an airway device to simulate lung breathing, a three-way valve, connecting tube, and air bag are used to simulate the lungs. Adjusting the valves and clamps simulates the changes in ventilator waveforms under different lung conditions. This solves the problem of lung damage to children caused by improper ventilator parameter settings and improves the trainees' operation and responsiveness.

Abstract

The utility model belongs to the technical field of medical apparatus and instruments, and concretely relates to a gas circuit device for simulating lung respiration demonstration, which comprises three-way valves, connecting pipes and air bag simulation lungs. The air bag simulation lungs are multiple and are respectively paired with the multiple three-way valves. The pipe opening at one end of the first three-way valve is connected with the pipe opening of the second three-way valve through the connecting pipe. The pipe opening at the other end of the three-way valve is connected with the air bag simulation lung. The gas circuit device is connected with the breathing machine, the various valves and clamps are adjusted, and the corresponding waveform changes and other parameters in the digital display screen of the breathing machine are observed, so that the correlation between the breathing machine setting and the pathological state of the lung of the sick child is understood, the gas circuit device of the simulation lung has high visibility and operability in the teaching machine training, and helps to cultivate the clinical thinking and practical ability of the trainees.
