dcsimg Elcam Medicals Marvelous stopcock

Stopcock uses Makrolon® polycarbonate for greater patient safety

New medical technology helps “reduce” infections from IV infusions

Hospitals are viewed as places for healing. Unfortunately, this is not always the case. People are surprised to learn that infections from intravenous infusions are a growing problem for hospitals.

3 Way Stopcock
Elcam Medical‘s Marvelous™ three-way stopcock uses Makrolon® polycarbonate from Covestro to help realize its design and maximum patient safety.

Task

To enhance patient safety when fluids are administered intravenously or by other means, Elcam Medical, a world-leading medical equipment supplier, set out to develop a product to help combat infections caught when administering IV fluids.

Challenge

Elcam Medical created the Marvelous™ (MRVLS) three-way stopcock. An integrated Luer-activated valve that acts as barrier against microorganisms and a novel inner channel that ensures self-flushing and minimized residual volume make it unique. The company needed a material that could withstand microorganisms, disinfection and was biocompatible.

Solution

Makrolon® Rx1805 polycarbonate from Covestro was developed specifically for IV components. This grade was chosen for the application because it is easily molded, transparent and has good dimensional stability, making it well-suited for reliable, precision molding medical devices. Makrolon® Rx1805 polycarbonate‘s biocompatibility makes it appropriate for use in medical applications requiring contact with body fluids. Its ability to be sterilized with radiation adds to patient safety.
