Talking about the practical application of Bluetooth technology in medical electronic equipment

The working frequency band of Bluetooth wireless communication technology is in the global 2.4GHz ISM (ie science, medicine, industry). The early Bluetooth data rate 1 Mb/s. frequency hopping technology divides the frequency band into several frequency hopping channels. In a complete connection, the radio transceiver continuously transmits from one channel to another according to a certain pseudo random code. The data of the transmitting and receiving parties in the Bluetooth wireless technology system communicates according to this rule, and other radio devices cannot work according to the same law. So Bluetooth wireless technology has largely suppressed the radio.

Bluetooth wireless technology has the advantages of stable transmission signal, no easy interference and no object obstruction. Under normal circumstances, Bluetooth technology can effectively replace medical monitoring sensors and analyzers, computers and PDAs on patients in traditional ward monitoring systems. Analyze the open cable between the devices.

The “wireless” real-time monitoring of the human life index is the common aspiration of doctors and patients, but there are inevitable defects based on traditional wired electronic technology. Bluetooth wireless technology can not only replace the data cable around the PC, but also meet the needs of patients around the care ward. The Bluetooth gateway in the hospital's intensive care unit can realize the seamless connection between the Bluetooth monitoring network and the wired LAN, so that the advantages of many different networks can be combined, so that the patient can provide a comfortable and simple environment.

The use of any medical equipment must first ensure the safety of the doctors and patients, and then it is possible to put them into clinical use so that they can be accepted by both doctors and patients. Often the safety of medical devices includes information security and ecological security.

Vaccine For Rabies Prophylaxis

Travelers to areas where rabies is endemic may be at risk, especially if they are likely to come in contact with animals in areas where dog or other animal rabies is enzootic and immediate access to appropriate medical care is unlikely. Canine rabies remains highly endemic in certain areas of the world. Need for rabies preexposure vaccination depends on the nature of risk and associated level of potential exposure. preexposure vaccination based on local incidence of rabies in the country to be visited, availability of appropriate agents for rabies postexposure prophylaxis in that country, and intended activity and duration of stay
