Check, back up, update: servicing a connected medical device via app
Starting point
Starting point
The device receives new firmware regularly and needs maintenance. Until now, an update meant a USB stick plugged directly into the device, an update program and manual input. The requirements:
- Secure update process: sign-in on the device, a backup before every change, verification before installation.
- Ease of use: service technicians and dealers should be guided through the process without needing specialist knowledge.
- Audit trail: every operation is logged.
Our solution
Solution
azena is building three components that work together:
- On-device service: runs on the device and accepts jobs.
- Service app: for mobile devices and tablets. The connection currently runs over the network, with Bluetooth Low Energy to follow; pairing is secured with a certificate.
- Guided workflow: find device → sign in → read modules → backup → transfer → verification → installation. Every step is logged.
- Service assistant: translates the device's error codes into plain language. Explanations with context from the device log are planned as the next extension.
Flow: technician app secured connection on-device service log.
Status
Outcome
As of September 2026: Sign-in, backup, transfer and verification run on the real device over the network. Installation has so far been simulated with test files.
Next: the same sequence via Bluetooth from a mobile device, followed by real installation using the manufacturer's update routine.
What we measure: update duration before and after, on-site visits avoided.
