I‘vehad my t Slim device for several months now and things seemed to be going ok. Lately though, I seem to be having a lot of leaking around my cannula which is very frustrating. Initially, I thought it might be a bad batch but had them changed. Still getting leaks! Seems to be after larger bolus doses but my pump is already set to give a bolus slowly. Any other tips? I’m using Autosoft 90 currently - would changing the angle or switching to a metal cannula help? Anybody have experience of metal cannulas? My fear is that they might be less comfortable - I’m already getting a bit of a rash with my G6 sensor so less irritation would be preferable.
