We are confused about Basic UDI-DI and would like some input on how you're all handling this, especially if you document systems that consist of a system and dependent accessories. In our case, we have monitors and dependent accessories that record things like blood pressure, oxygen saturation, pulse, and temperature. The monitor is meaningless without the accessories, and the accessories can't work without the monitor. Getting back to Basic UDI-DI, we're confused about whether we need to create a multitude of technical files for each accessory group (intended purpose and risk classification), or whether we can follow our MDD model of a system technical file with monitor and accessories, but have multiple DoCs, one for each Basic UDI-DI that applies using the criteria of intended use and risk class. Anyone run into this situation, and if so, how have you handled it?
