We have been having a problem with our Quick Set infusion sets. We have been using Quick Sets for 4 years without issue, and ever since that whole "Lot 8" issue, and having them replaced, we have had trouble hooking back up after unhooking!! My daughter unhooks for her shower, and then is not able to hook the pump back up. So we thought maybe there was some sort of issue with the towel getting stuck on it and messing it up or something (though we never had this issue before!!) so now we have her put the cap on when she unhooks. Still the same issue. She took a shower this morning, unhooked her pump, put the cap on and showered. When she finished, she took the cap off, and the pump would not hook back up to her site!!! This is incredibly annoying since, as far as I am concerned 3 days comes around quick enough, without having to change the site even more frequently!! Wondering if anyone else out there is having this issue, and if anyone has any suggestions??
