Abstract

The invention relates to an automatic wake-up circuit applicable to a cardiac pacemaker. A port level detection circuit and a high and low level judgment circuit are provided. The output end of the port level detection circuit is connected with the input end of the high and low level judgment circuit; the high level output end of the high and low level judgment circuit is connected to the port level detection circuit; the low level output end of the high and low level judgment circuit is connected to the cardiac pacemaker. Therefore, whether or not the cardiac pacemaker is connected to the heart can be judged through the port level detection circuit, the cardiac pacemaker is automatically controlled to switch to a running mode, no manual intervention is required, and operating is simple; meanwhile, the circuit is simple in structure and low in power consumption, a wake-up signal is sent out to activate the cardiac pacemaker only when the fact that the cardiac pacemaker is implanted in the human body is detected, management efficiency of pacemaker power consumption is effectively improved, battery power of the cardiac pacemaker is saved, and cost is lowered.

Description

technical field [0001] The invention belongs to the field of integrated circuits, and in particular relates to an automatic wake-up circuit applied to cardiac pacemakers. Background technique [0002] A cardiac pacemaker is powered by a single non-replaceable battery, which is generally required to work for 10 years or more, and the power consumption requirements are extremely demanding. For a pacemaker, it takes a long time to wait from the completion of production to implantation into the human body. During this period, the pacemaker should be in a dormant state to ensure that most of its internal modules do not work, so that the entire chip consumes power Minimal, reducing pacemaker battery energy waste. At present, the main method for changing the working state of the pacemaker is: after the pacemaker is implanted into the human body, the pacemaker is programmed to enter the normal working mode through an external program controller. This method requires manual interve...
