Embodiment

[0068] Example: A method for detecting the rate of change of the cross-sectional area of ​​the thoracic cavity based on a cardiopulmonary resuscitation simulator

[0069] The overall technical scheme and technical concept of the method are: under the action of the pressing head 9 of the cardiopulmonary resuscitation machine 7, the cardiopulmonary resuscitation simulator 6 is used to detect the motion data of each reference point on the simulated human thoracic cavity, and the measured motion data is used. and mathematical model to construct the curve equation of human thoracic contour, convert the curves of the human thoracic contour before and after the change into images respectively, and use the image area to calculate the simulated human thoracic cross-sectional area change rate.

[0070] like Figure 1-3 As shown in the figure, the cardiopulmonary resuscitation simulator 6 is a device used to simulate the change of the cross section of the thoracic cavity of the human bod...

Abstract

A method for detecting the change rate of chest cavity cross-sectional area based on a cardiopulmonary resuscitation simulator, characterized in that: under the action of pressing, the cardiopulmonary resuscitation simulator is used to detect the motion data of each reference point on the simulated human chest cavity contour, and the measured The motion data and mathematical model are used to construct the curve equation of the human thorax contour, so as to obtain the curves of the human thorax contour before and after the change, and use the curves before and after the change of the human thorax contour to calculate the simulated change rate of the cross-sectional area of ​​the human thorax. The invention establishes a brand-new method for detecting and simulating the change rate of the cross-sectional area of ​​the chest cavity of a human body, which is an innovation and breakthrough in the testing method and testing equipment of the cardiopulmonary resuscitation machine, and provides a new platform for testing and researching the cardiopulmonary resuscitation machine. It can also be applied to manual pressing or other pressing device testing.

Description

technical field [0001] The invention relates to the technical field of medical emergency devices and methods, in particular to a method for detecting the rate of change of the cross-sectional area of ​​the thoracic cavity based on a cardiopulmonary resuscitation simulator. Background technique [0002] Cardiopulmonary resuscitation, referred to as CPR, is a life-saving technique for the heart and breathing of sudden cardiac arrest. It is used to perform chest compressions on patients with acute cardiac arrest. At present, most CPR is mainly rescued by chest compressions, usually including mechanical and manual. No matter what compression mechanism is adopted, the ultimate goal is to change the cross-sectional area of ​​the human thoracic cavity at a certain frequency to achieve effective blood perfusion and prevent brain death in patients. [0003] Cardiopulmonary resuscitation machine, also commonly known as cardiopulmonary resuscitation machine, is a type of equipment tha...
