What is an Ash Cath?

The first day I ever dialyzed, the needle that carried to blood back to my body somehow shifted and I was infiltrated. That means it went back in under my skin and not into a vein. That resulted in a fast trip to the hospital where they put in an Ash Catheter. I hated this thing because I couldn't raise my hands over my head. I couldn't wash my hair and I couldn't take a shower. The path of the catheter is into your chest, up through the jugular vein and into your heart. It is easy to get infected, so it must stay covered at all times and sterilized and cleaned before and after every treatment.
