Wireless communication device for implantable medical instruments

Abstract

The invention relates to a wireless communication device for implantable medical instruments and belongs to the technical field of implantable medical instruments. The wireless communication device comprises an in-vitro transceiver and implantable in-vivo transceivers, and is characterized in that a communication frequency band covers 401MHz-406MHz and 420MHz-445MHz and is capable of achieving an adaptive frequency hopping function within the frequency band, one in-vitro transceiver can be in simultaneous real-time communication with a plurality of in-vivo transceivers, body penetrating communication distance is longer than 2m, modulation modes are flexible, communication rate and transmission power can be adaptively adjusted, the maximum communication bitrate is not less than 100kbps, and wireless communication can be simultaneously performed with existing wireless charging. The wireless communication device for the implantable medical instruments has the advantages of simple implementation mode, reliable communication processes, high intelligent degree and anti-interference capability, small size, low transmission power, long distance, high speed and the like, is capable of achieving a one-to-many communication function and can be widely applied to various implantable medical instruments.

Description

technical field [0001] The invention relates to an implantable medical instrument and a two-way wireless communication device, belonging to the technical field of implantable medical instruments. Background technique [0002] There are many types of implantable medical devices, such as implantable cardiac pacemakers, brain pacemakers, nerve stimulators, muscle stimulators, ECG recorders, etc., which are composed of implantable internal transceivers and external transceivers. Information is exchanged between them through two-way wireless communication. [0003] Communication technology for implantable medical instruments, characterized by low power consumption, miniaturization, and high reliability. Implantable medical instruments are generally powered by disposable batteries, and communication consumes battery energy, so low power consumption is required, especially low power consumption per bit; implantable medical instruments generally require as small a volume and weight...

AI Technical Summary

Problems solved by technology

[0004] The existing communication methods of implantable medical instruments are often limited by low speed, short distance, one-to-one, and poor anti-interference

This low-speed, short-distance communication method has problems such as high power consumption per bit transmission, real-time monitoring and remote monitoring inconvenience.
