<p>A port cap for attachment to an inlet or an outlet port of a device, especially a medical device such as a cardiotomy reservoir, venous reservoir, blood oxygenator or blood dialyzer. The port cap comprises a hollow body member having a wall at its first end, a second end which is open, and a hollow interior. The closed end of the body member carries a hollow projection having a first end which is closed and a second end which is open, the hollow interior of this projection being in fluid communication with the hollow interior of the body member. The cap has a weakened peripheral portion near its closed end so that its closed end may be twisted off to gain access to the hollow interior of the cap. The cap may comprise thread means on the inside surface of the body member near its open end or it may have thread means on the outside surface of the aforementioned projection between the weakened peripheral portion and the end wall of the body member. The cap may be used to cover or close the port of a device. It can thereafter be completely removed from the port or, alternatively, the closed end portion thereof may be snapped off to provide a site at which auxiliary medical equipment can be connected.</p> |
