WHAT IS BLUETOOTH?

Bluetooth is a radio technology that supports short-distance communication (generally within 10m) of devices. It can exchange information wirelessly among many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The use of Bluetooth technology can effectively simplify the communication between mobile communication terminal devices, and also successfully simplify the communication between the device and the Internet, so that data transmission becomes faster and more efficient, and broadens the way for wireless communication.
As a small-range wireless connection technology, Bluetooth can realize convenient, fast, flexible, safe, low-cost, low-power data communication and voice communication between devices, so it is one of the mainstream technologies for wireless personal area network communication. Connecting with other networks can bring a wider range of applications. It is a cutting-edge open wireless communication that allows various digital devices to communicate wirelessly. It is a type of wireless network transmission technology that was originally used to replace infrared communication.
Bluetooth technology is an open global specification for wireless data and voice communication. It is based on low-cost short-range wireless connections to establish a special connection for the communication environment of fixed and mobile devices. Its essence is to establish a universal radio air interface (Radio Air Interface) for the communication environment between fixed devices or mobile devices, and further combine communication technology with computer technology, so that various 3C devices can be connected to each other without wires or cables. In this case, mutual communication or operation can be achieved within a short range. Simply put, Bluetooth technology is a technology that uses low-power radios to transmit data between various 3C devices. Bluetooth works in the universal 2.4GHz ISM (industrial, scientific, and medical) frequency band and uses the IEEE802.15 protocol. As an emerging short-range wireless communication technology, it is strongly promoting the development of low-rate wireless personal area networks.

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.
