Microbial fuel cell for supplying power to implantable medical device

Abstract

The invention discloses a microbial fuel cell system for supplying power to an implantable medical device. The system is arranged in a transverse colon of a human body, utilizes intestinal micro-organisms and contents for generating power, and can be taken as an implantable medical device to provide energy. The anode of a cell is made from a material with good flexibility, conductivity, stabilityand biological compatibility, and is stuck to the inner wall of the intestine spirally; and the cathode is arranged in the middle of the intestine with higher oxygen consistency, and the peristalsis of the intestine is used for realizing continuous and stable power generation. The microbial fuel cell can use the intestinal micro-organisms and contents to generate enough power so as to meet the need of the implantable medical device, and can continuously generate power in the human body and have longer service life, thus providing a new technical path for solving the energy problem of the implantable medical device.

Description

technical field [0001] The invention relates to a microbial fuel cell for supplying power to implanted medical equipment. The battery can use microorganisms and contents in human intestinal tract to generate electricity to meet the power consumption demand of implanted medical equipment. The invention belongs to the technical field of biomedical engineering and is used to solve the problem of continuous and stable energy supply of implanted medical equipment. Background technique [0002] Modern medicine has developed many implantable medical devices (Implantable Medical Devices, IMDs) that can operate in the human body to assist or replace certain organ functions. At present, implantable medical devices have been applied to various parts of the human body. According to the demand for energy, implantable medical devices can be divided into two categories: active and passive, among which active devices such as cardiac pacemakers, cochlear implants and drug pumps require a ce...

Problems solved by technology

Although the lifespan of nuclear batteries can exceed 15 years, it may cause cumulative radiation damage in the human body, and its application is not safe and perfect. Therefore, it is necessary to find a more durable and safe power supply for implantable medical devices

[0004] In the early days, it was proposed to use glucose in the human body as fuel, oxygen as oxidant, and enzyme as catalyst to power the pacemaker. Although the reaction conditions are mild and the supply of raw materials is sufficient, the life of the enzyme is short and easily The long-term stable operation of the battery is affected by the cross-linking of macromolecular substances such as proteins and the loss of activity.

Weiner and others proposed that body heat can be used to generate electricity, but due to the small temperature difference between various parts of the human body, it cannot provide enough electric energy
