In vitro temporary cardiac pacemaker with measurement function

Abstract

The invention provides an in vitro temporary cardiac pacemaker with a measurement function. The in vitro temporary cardiac pacemaker includes a power supply, a power management system, a pacing measurement system, an input unit, a display unit and an electrode terminal, wherein the power supply is electrically connected with the power management system which is connected with the pacing measurement system; and the pacing measurement system includes a microcontroller, a pacing circuit, a sensing and measurement circuit, a defibrillation protection and EMI filter and a clock oscillation circuit.The microcontroller is connected with the pacing circuit, the sensing and measurement circuit and the clock oscillation circuit. The pacing circuit and the sensing and measurement circuit are connected with the defibrillation protection and EMI filter. The defibrillation protection and EMI filter interacts with the electrode terminal. The input unit is provided with an input interface, and the input interface is electrically connected with the power management system and the microcontroller. The display unit is electrically connected with the microcontroller. The in vitro temporary cardiac pacemaker with the measurement function can measure and display parameters such as a pacing threshold, myocardial impedance and P/R amplitude, to facilitate implantation of a pacing electrode and electrode fault monitoring.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to an external temporary cardiac pacemaker with a measuring function. Background technique [0002] Extracorporeal temporary cardiac pacemaker, it is placed outside the body, according to the prescribed procedures to issue electrical pulses with a certain frequency and energy, and transmit the electrical pulse signals to the myocardium through the electrode wires, so that a certain part of the myocardium generates an excitation point, and the A medical electronic device that conducts excitement to the entire heart, causes the heart to contract and relax, maintains cardiac output, and thus maintains the normal function of the heart. It is mainly used for therapeutic emergency temporary cardiac pacing, diagnostic or research cardiac pacing, prophylactic or protective temporary cardiac pacing and excessive temporary cardiac pacing. [0003] Currently, electrode leads are generall...

AI Technical Summary

Problems solved by technology

This will lead to life-threatening failures such as poor pacemaker perception, no pacing pulse output, failure to capture, etc., so these failures must be detected and avoided as soon as possible

[0005] So far, there is no external temporary cardiac pacemaker that can measure all parameters such as pacing threshold, myocardial impedance and P / R wave amplitude, and this technology has been blank.
