Provisional Patent Application Filed

Prevents touch contamination

This technology is a new peritoneal dialysis (PD) connection interface that simplifies the process of connecting and disconnecting a peritoneal dialysis cycler or solution bag. It is expected to reduce rates of PD-associated peritonitis. The technology features a redesigned transfer set and transfer set caps. The patient inserts a capped transfer set and capped disposable tubing (patient line) into corresponding entry ports at either side of an enclosure, where an embedded magnet uncaps both the transfer set and the patient line. Once both caps are removed, the patient can slide the tubes further in until the two connect magnetically, allowing flow of dialysis fluid to begin.

Easier and safer connection of peritoneal catheters

Peritonitis poses a serious risk for peritoneal dialysis (PD) patients. Touch contamination of the peritoneal tubing is to blame in nearly one-third of peritonitis cases. Current devices and aseptic methods require thorough hand washing, several steps and very careful handling of the transfer set and caps. These steps can be complicated and overwhelming for patients, especially frail, arthritic, disabled, distracted or visually impaired patients. This new device is a connection interface that eliminates the risk of touch contamination. It reduces the number of steps to connect and disconnect from their cycler or solution bags.
