IoT Network Puts Defibrillator Management in Hands of Suppliers

With CardiLink's Medtech AED device-monitoring system, using Asavie IoT Connect, makers and suppliers of life-saving equipment can help customers manage the location and condition of each item automatically.

CardiLink provides an application programming interface (API) for manufacturers, which can then build the technology into their own branded applications to manage and display the data. To use the system, a manufacturer or supplier first scans in the unique ID number of a particular CardiLink device, then links it to the serial number of the specific AED, which is deployed by the company's customer. The sensor identifies any movement or the opening of the device, as well as its battery level. It beacons an alert via a cellular connection to the CardiLink server, using the private Asavie network, according to Hugh Carroll, Asavie's VP of marketing.

With the CardiLink service, users can access the cloud-based server and view a list of their AEDs, as well as their service status and history. The system displays those items that require servicing immediately, or in the near future, highlighted in either orange or red. Users can also view the locations of those AEDs as icons on a map of their deployment area. The CardiLink unit comes with a battery with a two-year lifespan. However, that lifespan can be adjusted based on the service cycle, or on the timed frequency of transmissions.

In the long run, CardiLink hopes its solution will lead to more AED deployments in public areas. Traditionally, Wassermann says, some companies or organizations have been reluctant to put many AEDs in public places, simply because they are vulnerable to theft or damage—and ensuring they are properly maintained poses a challenge. With the CardiLink and Asavie service, he says, both problems could be alleviated. "The challenge has been in creating the awareness around the need for AEDs" in public places, he adds.

For wireless IoT connectivity, Carroll reports, manufacturers have shown a preference for solutions using cellular networks. "Trust is at the heart of the solution," he says, and they want to be sure that transmission will always be possible. Wi-Fi or other low-power technologies could potentially go down, creating transmission gaps or bandwidth constraints. "There are always issues around connecting to a corporation's Wi-Fi—and in this case, human lives are at stake."

Asavie's technology operates on private networks for each customer, based on relationships with local cellular service operators. While the technology allows manufacturers and distributors to offer value-added services, Wassermann says, the ultimate goal is to ensure lives can be saved. "Our priority is patient safety," he states.
