US 6,632,203 B2 · Sampling port for a drainage device

Abstract

A sampling port having a mechanical valve for a drainage apparatus is disclosed which permits a practitioner to directly access a collection chamber of the drainage apparatus using a needle-less syringe for withdrawing a sample of fluid therefrom. The sampling port comprises a port in direct communication with the collection chamber and a mechanical valve partially disposed inside the port. The mechanical valve comprises a generally tubular body containing a spring loaded valve that is normally closed to fluid flow communication and operable using a needle-less tip syringe to actuate the valve. In operation, a practitioner engages the needle-less tip syringe to the valve which places the valve in an open position and permits fluid flow into the syringe as the practitioner draws back on the plunger of the syringe.
