Digital Medical's platform streamlines inventory managment and tracking of hospital equipment.
The founders wanted to build a comprehensive system that would perform indoor location tracking of surgical equipment in hospitals. A service like this has many potential pitfalls; Bluetooth signals in active spaces, operating restrictions within hospitals, an industry that's slow to change, and large and well-funded competitors, just to name a few. We wanted to bring a novel solution to market that would undercut the cost of other product offerings and perform more reliably.
What We Did
Process & Technology
We built a highly distributed system of Raspberry Pi receivers running a customized Linux environment. These receivers listen for Bluetooth signals from beacons attached to devices throughout hospitals, and send them to a centralized system via WebSockets, which runs in AWS Elastic Container Service as Fargate instances. The system in AWS decides which beacon is in what room. We developed an algorithm to make this determination efficiently across thousands of devices in an instant. This entire part of the system is written Go, and it pushes beacon positions to a Ruby on Rails application over a WebSocket, which records each position in a Postgres databse. Users can watch the positions change live in their browsers in a floor map view, with no need to referesh the page, thanks to WebSockets' push capabilities.
We took a deep dive into a new set of technologies and set out to solve very difficult technical challenges. We developed a novel, scalable, and efficient solution, which has been successfully deployed in hospitals across the country.
Goji Labs has done an exceptional job at building our products and getting them to where they need to be today. Their knowledge, timeliness, and thoroughness set them apart.
