PPE seals reduce costs and improve patient experience

Application

New seal design for OEM of portable Haemodialysis machine used by patients at home.

Problem

The SelfCare+ machine receives water from a reverse osmosis machine, heats it to body temperature and then, using a disposable cartridge, it generates high quality bicarbonate-based dialysate on demand. Incumbent Nitrile O-rings required high forces to close the machine door, which required reinforcement. Failure to seal between door and cartridge results in leakage of acids and other transfer media.

Solution

PPE designed a new door seal using silicone materials S60A (blue) and S60H (white) which was validated using FEA and physical testing. Desired closure force was attained, allowing the OEM to design a lighter door thus improving the patient experience.

Outcome

Improved patient experience, increased life-time of seals, reduced forced maintenance periods and significant cost savings.
