Cateter cable insulin

This morning I put the breakfast bolus and when I had already happened to me the entire insulin I saw how there was something in the cable that I think was insulin, I still have that in the cable anyone know what it is?

Hello, I don't know if you explain yourself very well.If you are referring to the infusion set tube, what happens quite frequently is that they appear as short whitish areas.At first I thought they were air bubbles, but it turns out that they don't move as you consume the insulin.In the Reddit forum about the 780G system (which is what I use) I read that the tube actually has a complex internal structure, with an inner tube through which the insulin passes and the outer plastic.The white areas are spots where the inner duct has become detached from the outside or something like that.And what is important, this does NOT affect the insulin infusion.
