Brazilian Hospital Improves Care for ICU Patients

Santa Casa de Valinhos deployed an Internet of Things solution from Taggen RFID Solutions that facilitates the location of its equipment.

Taggen's localization platform consists of three components. A cloud server provides an administrative interface, dashboards, reports and an application programming interface (API). Small reader modules (known as Taggen Gateways) are installed in the rooms to be monitored. "These modules communicate with the central server via a Wi-Fi network or the client's own wiring," Prado states. Finally, active tags (called Taggen Beacons) are detected by the readers. The system collects location and telemetry information, such as battery level, ambient temperature and so forth.

The solution was integrated with the company's management system, which is the front end preferred by users—the technicians who carry out maintenance at the hospital. Readers are installed in hospital beds, and the system identifies the beacons within 100 meters (328 feet). The cloud server has the intelligence to determine each tag's exact location, even though it is being detected by multiple readers simultaneously.

The Cricket localization system was developed by Biocam, based on Taggen's RTLS platform, which utilizes readers and Taggen RFID tags. Electronic engineering is the result of a partnership with the CPqD institute, located in Campinas.

According to Prado, the project was carried out in two phases. During the first phase, equipment located in the ICU sector and considered more critical was identified with beacons. "Currently," he says, "an expansion is underway and 133 more mobile devices are being identified."

The active tags (beacons) can be reused in the event that a device is replaced. Each tag has a replaceable, long-life battery that reaches a 10-year usage period, according to the manufacturer.

Prado says there were no major challenges for the system's operation. "The main thing was a small adaptation of the hospital's Wi-Fi network coverage," he states. "With the initial deployment success, we want to increase the number of readers to extend the coverage area and the wired network deployment in the equipment."
