A Pneumatic Response Cardiopulmonary Resuscitation Teaching Simulator

Abstract

The invention relates to a pneumatic reaction cardiopulmonary resuscitation teaching simulation human model. The pneumatic reaction cardiopulmonary resuscitation teaching simulation human model comprises a breathing mechanism, a pressing mechanism, a force sensor, an acceleration sensor, a controller and a pressure sensor, wherein the breathing mechanism comprises a lung simulator, the pressing mechanism comprises a chest simulator, before resuscitation, the chest simulator is controlled by a proportion pressure-reducing valve to simulate hardness of a human thorax, a pupil simulator realizes air intake to simulate a pupil amplification state, and a carotid simulator realizes air intake to simulate a carotid beating stop state. When a chest portion of an upper human body model is pressed, the carotid simulator beats according to the pressing frequency of the chest simulator to simulate the carotid beating state; when the upper human body model is gassed, the lung simulator simulates an artificial respiration state; after recovery, the pupil simulator exhausts to simulate a normal pupil state, and the carotid simulator is controlled by the proportion pressure-reducing valve to simulate the normal carotid beating state. According to the simulation human model, the simulators are driven through air to simulate symptoms of organs such as the chest, the lung, the eyes and the neck before and after cardiopulmonary resuscitation, and vivid symptom simulation effects and accurate positioning are realized.

Description

technical field [0001] The present invention is a pneumatic response cardiopulmonary resuscitation teaching simulator applied to medical teaching, in particular a pneumatic response cardiopulmonary resuscitation teaching simulator provided to trainees for cardiopulmonary resuscitation skill training by simulating human chest compression and artificial respiration . Background technique [0002] In the teaching of CPR, the traditional method is to let students conduct experiential teaching on actual patients. However, experiential teaching on the patient's body is prone to medical disputes, and there are human rights and other related issues. Therefore, the use of cardiopulmonary resuscitation teaching simulators to carry out simulation experiment teaching for students has important practical significance. [0003] At present, the cardiopulmonary resuscitation teaching simulators for clinical application mostly use mechanical compression devices powered by springs in chest ...

AI Technical Summary

Problems solved by technology

Although the device can respond to changes in the chest compression depth according to the force sense of the students, due to the high rigidity of the internal mechanical system, the symptoms displayed are quite different from the real situation, and cannot allow students to obtain high-quality experiential teaching effects
