Health service network based on human body communication system

Abstract

Provided is a human body communication system, comprising a plurality of nodes capable of being distributed at parts inside and outside a human body. The nodes communicate with each other by using the human body as a medium, and form a corresponding network topology structure as required. Each node comprises a wearable or implantable medical device, a communication interface, a human body communication transceiver and an electrode using human body as a communication medium. The wearable or implantable device is connected to the human body communication transceiver via the communication interface; the human body communication transceiver is connected to the electrode, and transmits data to other human body communication transceivers via the electrode. The working frequency of the human body communication transceiver is less than 100 MHz. Further provided is a health service network based on the human body communication system.

Description

technical field [0001] The invention relates to a health service network, in particular to a health service network based on a human body communication system. Background technique [0002] At present, the concept of early disease prevention, early intervention and early treatment has been gradually accepted by everyone, which proposes a possible solution to alleviate the problems of ordinary people's difficulty in seeing a doctor and the cost of seeing a doctor. The key technology for the realization of the above-mentioned "three mornings" concept is to continuously and real-time monitor various physiological parameters of the human body, and possibly intervene. The development of electronic communication technology makes the above scheme possible, and its design must meet the following conditions: (1) The transmission method has no negative impact on the user's physical health; (2) The data transmission must be stable and not affected by the human body; (3) ) Low working ...

Problems solved by technology

[0003] However, in the existing communication technologies, the communication distance between Bluetooth and Zigbee is relatively long, and it is easy to cause overlapping coverage areas between different human bodies, which reduces system security and system throughput; the power consumption of Bluetooth and WiFi is high, The data rate of Zigbee is too low; the data rate of RFID and NFC is also too low, and the networking is not easy

In addition, the above-mentioned RF wireless technologies are all faced with the influence of the "shadow effect" in wireless communication, which leads to large-scale fading of communication in relevant parts of the human body, and affects the real-time and robustness of the system.

Therefore, the use of the above-mentioned communication technology has caused the most important performance in the monitoring of human physiological parameters, such as power consumption, security, and communication robustness, to be greatly reduced.

At the same time, traditional monitoring focuses on individuals, and exchanges between individuals (such as face-to-face communication between doctors and patients, etc.) must be routed through different networks or directly operate terminal devices, etc., resulting in cumbersome communication between individuals and making it popular and operability are affected
