Description

technical field [0001] The invention relates to a conversion device and a conversion method for wireless ECG signal transmission, belonging to the related technical field of medical ECG monitoring. Background technique [0002] At present, the known medical ECG monitor picks up the ECG signal of the human body through the lead wire, and monitors the respiratory frequency and amplitude by collecting the change of the thoracic body resistance when the human body breathes, and alarms when the lead falls off. If you want to transmit data wirelessly on the ECG monitor you are using, the ECG monitor needs to disconnect the original ECG acquisition circuit and install a wireless receiving circuit, and rewrite the program to analyze the wirelessly received ECG information before it can be displayed on the screen. on display. In actual implementation, there are many brands and models of ECG monitors in use in hospitals. It is very difficult to transform the ECG monitors in use, and ...
