ABSTRACT:
A seal for limiting access of bacteria through a side arm of a stopcock such as that used in apparatus for monitoring pressure in a human blood vessel. The seal has a generally cylindrical body, an open end of which slides over the side arm. A portion of the body seals against the side arm exterior wall. The other end of the seal forms a cap through which a syringe nose may penetrate to establish fluid communication between the syringe and the side arm lumen. The interior of the seal body includes a recess for a Luer lock fitting which may exist on the end of the side arm, and an annular spacer projecting from the inside of the body to provide a surface against which the end of the side arm can abut to prevent the inserted syringe nose from bottoming on the end of the stopcock arm during use. A slit in the capped end of the seal facilitates insertion of the syringe nose. The slit is surrounded by a recess to guide the syringe nose into the slit. The inside of the cap is provided with an additional dome of material to increase the sealing contact between the cap and the syringe nose and so that line pressure in the side arm will help keep the slit closed tight around the end of the syringe nose. A further recess is provided in the seal body adjacent the inside of the cap to receive the material displaced when the syringe nose penetrates the cap.
