Abstract

The invention discloses an in-vivo MEMS micro-vibration energy collection based cardiac pacemaker energy system. The cardiac pacemaker energy system comprises an MEMS human body micro-vibration energy collection module used for collecting micro-vibration energy and converting the vibrational energy into electric energy to be stored, an MEMS power supply magnetic shielding packaging part, an information collection module used for collecting an electrocardiosignal of a human heart to generate a pace-making operation instruction, and a pulse electric control module used for generating a pulse voltage to perform pace-making stimulation on the human heart. According to the cardiac pacemaker provided by the embodiment of the invention, the cardiac pacemaker can collect the vibrational energy generated by the micro-vibration of the human body and can convert the vibrational energy into electric energy, so that the service life of the cardiac pacemaker is prolonged, the use cost is lowered, the adaptation of the cardiac pacemaker is improved, and reliability of the cardiac pacemaker can be well guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cardiac pacemaker energy system based on MEMS (Micro ElectroMechanical System, Micro Electro Mechanical System) micro-vibration energy collection in the body. Background technique [0002] In related technologies, most implantable cardiac pacemakers use disposable lithium batteries as the main energy source. Once the battery energy is exhausted, a new battery needs to be replaced through surgery, which not only increases the patient's physical and psychological pain, but also increases the cost of medical treatment. cost. [0003] According to research, patients have the highest demand for pacemakers in DDDR (dual chambers paces, dual chambers sensed, dual response to this, and rate modifiable, atrioventricular omnipotent pacing frequency adjustment) mode, which is 59%. However, the imported lithium batteries used in high-end imported pacemaker devices currently on the...
