What are the applications of wireless sensor networks in medical services?

Wireless sensors are used in medical services.

A wireless sensor network is usually a large-scale spatially distributed network, with hundreds of nodes distributed randomly or with a certain geographical location, and the purpose is to detect or perceive some specific parameters in the environment. The initial application of wireless sensor network is to detect some parameters in an open environment. Initially, it was used by the military for monitoring on the battlefield and some scientists and environmental researchers used it to detect climate change and forest environment and groundwater. However, when the wireless sensor network became a hot field, its application range also began to expand. In the field of medical services, we can see that wireless sensor networks are extended to wireless body area networks (WBAN) or wireless human sensor networks (WBSN). With the development of smaller and more powerful sensors, standards have been born to replace or redraft the management of these devices, for example, IEEE802.11 and IEEE802.15 standards organizations, wireless sensor networks, these changes are all achievable. The other is to introduce the wireless topology network WMN. Some companies or service providers will expand an access range to the wired network. This field will challenge the conventional wired network architecture. This kind of wireless topology network integrates the wireless human sensor network, creating a wireless human sensor topology network. This network mentioned applies to medical service monitoring. In the monitoring, the patient can measure his physical condition, such as blood pressure, body temperature, and pulse, as long as he wears a wearable sensor node. In this way, the information is uploaded to the router or gateway and finally transmitted to the central server to form the patient's medical record database. Wireless sensor networks can also be used for remote patient detection. In this case, you only need to install wireless sensor nodes at home, and these nodes can be connected to the Internet or other communication networks, and can also transmit data to Medical service equipment. This provides very convenient medical services for the ever-expanding elderly population, and at the same time it also increases the business of medical equipment entering the home and elderly medical equipment. In the case of increased demand, most of the applications of wireless sensor networks appear in remote patient monitoring examples, which notify the alarm system when the patient's condition exceeds a certain threshold. When the patient's information is recorded in the medical service equipment, the wireless sensor network can also notify and send important patient information through the emergency alarm device, so that medical workers can be fully prepared for the emergency. These sensor networks have potential advantages to improve the quality of medical services in the service area.
