Aha, "in the mob"!
Well back in those days I sometimes got roped in to carry out what was known as "the investigation of defects". And, if I remember correctly, in many cases there was no "defect" at all ... and the root of the equipments' tendency to disappoint was often what we might call "operator error" ("finger trouble", failure to follow laid down drills or procedures, or what-have-you).
Then, as now, I always tried to proceed in a methodical manner. For instance, I would start with a series of questions, in order to establish - identify - the problem.
So, in the case being considered ... what is the actual problem? And how does it manifest itself? "Low battery", "End battery" ... or some other indication?
These devices are not new; they have been in common use for a number of years now. Has this battery problem always been an issue with these little pumps, or have they (somewhat mysteriously) only recently started to occur?
Are the correct (recommended) batteries always being used? In other words 6LR61 (or whatever type MHRA or whomever are now suggesting)?
When examining the battery compartment of failed devices ... is any obvious damage evident? Misshapen (or tarnished) battery contacts ... worn or damaged plastic runners at the far end?
Maybe someone can remind us how many full deliveries each battery is normally expected to provide.
Yes, of course "it's important to ensure drug infusion therapy is not interrupted". But remind us ... when failure occurs, is it OK to just swap in a fresh battery and carry on? Not so easy to do quickly when on a patient, perhaps (with Lockbox etc
