Abstract:
Heart defibrillation monitor is a key device in rescuing patients with cardiac arrest,and its performance directly determines the success rate of rescue.The control circuit of the heart defibrillation monitor is a control module for charging and discharging during the defibrillation and electric shock process.Functionally,it is divided into control module of direct current(DC)inverter,energy storage capacitor charging module,cardiac defibrillation discharge module,and cardiac defibrillation monitoring module.In them,the energy storage capacitor is the core component of the control circuit.During the charging process,the energy storage capacitor stores charges,and it releases charges during the discharging process,which can provide control functions for effective implementing defibrillation and electric shock.The control accuracy of the heart defibrillation monitor is high,and its structural performance is constantly improving.The equipment's users and engineering support personnel need to master its structural composition and working principle,and be familiar with the fault analysis and handling process,and timely and effectively handle faults and restore normal operation of equipment.This study analyzed the structural composition and working principle of the control circuit of the heart defibrillation monitor.According to the control mode of charging and discharging,it analyzed the methods of analyzing and handling common faults of the heart defibrillation monitor,so as to improving the quality of operation management and clinical services of equipment.
