Low-power wireless power acquisition transmission system and method for cardiac pacemaker

Abstract

The invention discloses a low-power wireless power acquisition transmission system and method for a cardiac pacemaker, and relates to the field of data acquisition. The system includes an in-vitro circuit and an in-vivo circuit. The in-vitro circuit includes a low battery alarm circuit module, a button 1, a button 2, a power supply module, a power display module, a micro control chip (MCU1) and awireless data transmission module 1. The in-vivo circuit includes a wireless data transmission module 2, a micro control chip (MCU2), a power acquisition and battery life estimation module, and a measured cardiac pacemaker lithium-ion battery. A user sends a power acquisition request by pressing the button 1, and a sent command wakes up the wireless digital transmission module 2 of the in-vivo circuit. When receiving the data, the wireless data transmission module 2 wakes up the micro control chip (MCU2) through a pin level change interrupt, receives power information and transmits the power information to the in-vitro circuit. The system can view the power of the pacemaker and the battery life estimated information at any time, and each module is in a sleep state when being in an idle state, which greatly reduces power consumption.

Description

technical field [0001] The invention relates to the field of data acquisition, in particular to a low-power wireless power acquisition and transmission system for cardiac pacemakers and an implementation method. Background technique [0002] For patients with heart disease such as severe bradycardia and atrioventricular block, implanting a cardiac pacemaker is a reliable means of treatment. After the pacemaker is implanted in the human body, its working status and battery power need to be monitored at any time. Failure to do so could result in life-threatening pacemaker disturbances, incompatibility with the spontaneous heart rhythm, or depleted batteries. Existing monitoring methods, such as 24-hour Holter inspection and remote monitoring methods based on the telephone network, etc., but these methods have problems such as high power consumption, poor real-time performance, data transmission distortion, and limited range of activities of patients.
