Bluetooth Low Energy Technology In Health Care Industry

- Nov 20, 2019-

In recent years, with the low power consumption of Bluetooth technology and the high penetration rate around the world, as well as its signal transmission and the ability to create large equipment networks, various Bluetooth innovations are used in commercial applications such as retail, hospitality, tourism and medical. Bluetooth technology is now an important technology to enhance the experience of patients and healthcare professionals.


All-Round Connection

From fitness trackers to smart watches to blood glucose monitors and pulse oximeters, Bluetooth wearables have taken over the connected device market. In the wave of wearable device innovation, the market needs more and more monitoring equipment that can support medical diagnosis and care. As a result, Bluetooth technology is increasingly being used to replace wired products in recovery rooms, operating rooms, and intensive care units (ICUs).

Bluetooth technology has greatly improved security and signal range after several new extensions, and enhanced asset tracking and navigation capabilities, which expands the application of Bluetooth technology in medical institutions. For example, patients and visitors in large hospitals or medical parks can easily find routes via Bluetooth, and health care providers can quickly find locations for hospital assets such as critical medical devices, as well as patients who need urgent care.

Frequency Hopping

Healthcare organizations are often not comfortable with adding RF technology to a wireless signal-saturated environment, which may discourage Bluetooth technology. If there are too many devices transmitting on a channel with high usage, RF interference and distortion will occur. But Bluetooth technology uses adaptive frequency hopping (AFH) technology to minimize the effects of environments that are full of wireless signals.

With adaptive frequency hopping technology, Bluetooth devices can detect which channels are in use and avoid them by skipping, thus reducing the RF impedance and preventing the transmission of Bluetooth data packets getting interfered by the largest sources of interference. Bluetooth technology is therefore ideal for adding to any wireless infrastructure.


Low Power Consumption

Since the adoption of low-power Bluetooth in 2010, Bluetooth has been helping to optimize the energy consumption of battery-powered devices that are used to transfer small amounts of data to local user interfaces such as tablets and smartphones.

There are many medical devices that use this technology to improve patient condition monitoring and care devices such as blood glucose monitors, asthma inhalers, and implantable cardiac defibrillators (ICDs). Because of the high energy efficiency of Bluetooth low energy, these devices can run for years with a small button battery. Low-power Bluetooth also helps medical institutions’ environmental sensors and ward monitoring devices meet compliance requirements.

Large Equipment Network

There is a growing need for a comprehensive and secure network of wireless devices in the commercial and industrial sectors, and the medical environment benefits from the increased security, reliability and scalability offered by such networks that span the entire organization.

Bluetooth mesh networks can help create large device networks and are ideal for control, monitoring, and automation systems that enable tens, hundreds, or thousands of devices to communicate reliably and securely. Through the Bluetooth mesh network, healthcare professionals can see patients in real time and accelerate the response of emergency services, helping healthcare organizations reduce costs, optimize patient care and improve operational efficiency.
