Swallowable-type electronic capsule energy management module

Abstract

The invention discloses a swallowable-type electronic capsule energy management module, and the module mainly comprises a button cell, a non-contact type switch, a main controller, a condition gating type step-up circuit, a power router, a threshold voltage detection circuit, a reference voltage chip, and a negative charge pump. The module employs the main controller for monitoring the output voltage of the button cell, and carries out the high-efficiency, low-power-consumption and intelligent management of the energy of an electronic capsule under the condition that the space and resource are limited. The module avoids the useless consumption of energy to maximum degree, and prolongs the service life of the cell.

Description

technical field [0001] The invention relates to medical equipment, in particular to an energy management module of a swallowable electronic capsule. Background technique [0002] Swallowable electronic capsules can be taken orally into the digestive tract, and the images in the digestive tract can be transmitted wirelessly to the outside of the body through the micro-camera system carried by it, or the multiple sensors in the capsule can be used to detect and collect multiple information in the gastrointestinal tract. The institution takes a sample biopsy of the local tissue. Since the electronic capsule is located in the digestive tract, the cable-type energy supply method cannot be used, and the electronic capsule works for a long time in the digestive tract, and the space in the capsule is limited, thereby restricting the volume of the energy supply device. How to ensure the reliability and stability of the electronic capsule's energy supply is a key technology that need...
