Bi-directional digital wireless pressure monitoring system for biology implantation joint

Abstract

Implanting organism in knuckle bidirectional digital wireless pressure surveillance system, referring design of low-power consumption circuit, piezoelectric ceramic intermittent power supply circuit and data radio transmission circuit, belonging to medical implanted knuckle pressure surveillance system technical area which containing internal part : piezoelectric ceramic equipment, energy storage equipment, hybrid modulus chip, antenna; exterior part: exterior wireless data transfers source and sink equipment, computer-controlled and disposal equipment; there are three working in the system: piezoelectric ceramic equipment, energy storage equipment and hybrid modulus chip united working, system dormancy manner. This invention used to check the working status of organism implanting knuckle early. The power consumption is low; first realizing the communication between organism implanting knuckles and exterior, making the exterior computer can obtain press data by wireless manner in order to carry through the reasonable diagnose for implanting knuckles.

Description

technical field [0001] The invention relates to a bidirectional digital wireless pressure monitoring system for biological implant joints, in particular to low power consumption circuit design, piezoelectric ceramic intermittent power supply circuit design and data wireless transmission circuit design, and belongs to the technical field of medical implant joint pressure monitoring system. Background technique [0002] Physical disability is one of the important diseases that affect the quality of life of the disabled. Artificial joints and prosthetics are an important means of re-establishing motor function for people with joint damage. After the artificial joint is implanted in the human body, it is in a long-term working state. Integrated circuit technology is used to establish a physical channel for signal transmission between the human implanted joint and the outside world, and early monitoring of the working conditions, pressure, and dislocation of the implanted joint. ...

AI Technical Summary

Problems solved by technology

However, this model is only limited to the experimental stage, without considering the actual application environment, and many parameters are not set according to the actual situation, and there are the following three problems: 1. It is only a functional application of the experimental environment, and does not consider the low power consumption that can be applied in practice 1. Low voltage and low noise circuit design; 2. The design of the in vitro circuit is not considered, that is, how to wirelessly transmit the data in the joint to the outside of the body; 3. The design of the power circuit is lacking

[0004] At present, there is no research on the detection of implanted joints using microelectronics technology
