Here’s something tangentially related that makes it difficult to find older options, the support. In the US a piece of medical device has to be supported for 7 years. My hospital has these bladder scanners that are in quite a few departments, regular fixture in hospitals (ultrasounds). Jan 1 2024 was when our came up on the 7 year mark. To do preventative maintenance calibration required logging on their server, guess what’s no longer accessible? So to stay in compliance all of us in the biomed department has to figure out how to get new ones to replace the 10 $11k each paperweights we have now.
