Application of Bluetooth technology in the field of medicine

With the vigorous development of modern medical undertakings, the emergence of hospital monitoring systems and medical consultation systems has made outstanding contributions to the development of modern medical undertakings. However, there are also some problems in the actual application process, such as the current monitoring equipment for critically ill patients The wired connection will inevitably affect the normal operation of the monitoring instrument when the patient has activity needs, but the emergence of Bluetooth technology can effectively improve the above situation. Not only that, Bluetooth technology also plays an important role in the transmission of diagnosis results and ward monitoring.

Delivery of diagnosis results.

Relying on Bluetooth transmission equipment, the hospital’s diagnosis results are delivered to the memory in time. The application of the Bluetooth stethoscope and the Bluetooth transmission itself consume less power and the transmission speed is faster. Therefore, the electronic device is used to transmit the diagnosis results in a timely manner to improve the diagnosis efficiency of the hospital and ensure the accuracy of the diagnosis result data.

Ward monitoring

The application of Bluetooth technology in hospital ward monitoring is mainly reflected in the bed terminal equipment and ward controller. The main control computer is used to upload the bed terminal equipment number and the basic hospitalization information of the patient, and the hospital bed terminal equipment is equipped for the inpatient. Once the patient has an emergency Status, use the terminal equipment of the hospital bed to send a signal, and the Bluetooth technology transmits it to the ward controller in the way of wireless transmission. If there is a lot of transmission information, it will automatically divide the transmission registration according to the signal mode, which provides great convenience for hospital ward management.
