I'm not fully abreast on all the in's and out's of his care, but I know that he does put a new catheter (I think thats whats its called, the long plastic tubing with the adhesive and the needle) in, I think it's generally around the same spot (maybe a couple inches difference), on one of the sides of his abdomen, because thats where it works the best for him. He tried the legs, but it was more bothersome for him, so to the abdomen it went. He's usually pretty private about it, but sometimes he's cool and shows me how it works. He's shown me all the pieces before, as well as how they all work together and how to use them. He's taken my blood sugar before to show me what it's like- and I can say that I definitely don't like getting the poke in the finger!! (His pump has a blood sugar monitor, but it's too difficult for him to read it think, so he does it the old fashioned way with large print numbers) He's also showed me how he can tell when he needs to add insulin to his pump and how to do it. It's pretty awesome, because it's very automated. The only problem he realy encounters (re: the blindness) is getting the pump correctly calibrated to his body. He recently had to get a new one when a piece broke, and that was a bit difficult, getting all the settings correct. (because it was shipped right to his house, not to the dr) but his roommate took the course along with him and was able to help him out.
Best advice I can give you, is to always make sure you have extra supplies with you, whether it be a couple extra catheters or what not. My brother has had to learn the hard way that occasionally, the catheters dont always go in like theyre supposed to (not sure if this is catheter error, or due to his blindness) and he's gone through a couple of them at a time and been woried that he would run out earlier than expected if he was spending a few days at our house. Now we make sure that we stock supplies at our house too, just in case.
Another thing thats always been helpful for him, is that he has a tiny fridge (similar to those that kids have in dorm rooms) that he keeps in his room so that the insulin (and a few sugared drinks in case he does get low) can be kept separate and accessable. (Most helpful when living with a roommate, or if the kitchen is on another floor).
Other than that, he just hooks the little pump to his belt buckle or in his pocket, just as anyone would with a cell phone.
o, now that I've probably bored the rest of the forum...lol... but seriously, ask any questions you want. I may not have the answer, but then again, I might surprise ya!
