DEVELOPMENT OF A LOCAL BIOMEDICAL SIGNAL COLLECTION NETWORK BASED ON ZIGBEE TECHNOLOGY

The article describes a methodology for developing a local network for remote monitoring of patient biomedical signals based on low-speed energy-saving ZigBee technology. The local network is based on two transmitters and one receiving module connected to the server. Transmitters transmit information from sensors about the condition of two patients (temperature, pulse, blood flow) to the on-site server. Information is displayed in a specially designed interface that is easy to visualize. In addition, audio elements are connected to the transmitting equipment to alert medical personnel if biomedical signal thresholds are exceeded. Thus, it is possible to monitor the condition of two or more patients (in one department, the number of transmitters can be in the dozens, thanks to the branched ZigBee topology).
In the future, it is planned to increase the number of transmitting modules to create a large local monitoring network in a single medical institution. In addition, there is the prospect of collecting more biosignals, including ECG, body position, oxygen saturation of the patient’s blood, etc.
