AI Technical Summary

Technical Problem

Existing cardiopulmonary resuscitation (CPR) machine performance verification suffers from problems such as limited functionality, discrete data, reliance on manual intervention, and simulation distortion, resulting in low testing efficiency, poor accuracy, and limited clinical reference value.

Method used

Design a multi-parameter testing fixture for a cardiopulmonary resuscitation machine. By replacing elastic components with different elasticities, it can achieve equivalent simulation of the chest cavity elasticity of adults or children, simultaneously collect force and displacement signals, and conduct integrated testing and analysis of compression depth, frequency, duty cycle and long-term stability. A printed circuit board assembly is used for data processing, providing a unified hardware time reference and multi-channel synchronous sampling.

Benefits of technology

It achieves highly synchronous, integrated, and automated testing of cardiopulmonary resuscitation machine performance, improves testing accuracy and efficiency, supports long-term unattended aging testing, and enhances clinical reference value.

Abstract

The invention belongs to the technical field of cardio-pulmonary resuscitation machines, and discloses a multi-parameter testing tool of a cardio-pulmonary resuscitation machine and a using method. The tool comprises a fixed shaft and a data acquisition module, the fixed shaft is sleeved with an elastic piece, the top of the fixed shaft is sleeved with a sleeve, the sleeve is connected with a pressing plate, and the sleeve is detachably installed on the pressing plate; the bottom of the pressing plate is connected with a pressure sensor. The bottom of the pressure sensor is connected with a displacement sensor. The pressure sensor and the displacement sensor are both in communication connection with the data acquisition module; a shell is arranged outside the fixing shaft, a through hole is formed in a top plate of the shell, and the through hole is formed above the pressing plate. According to the invention, equivalent simulation of chest elasticity of different objects such as adults or children can be realized, and integrated test and analysis of pressing depth, pressing frequency, pressing duty ratio and long-term stability (aging) can be realized by synchronously acquiring force and displacement signals.
