摘要： 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.

摘要： A drainage device comprising an improved vacuum regulator assembly is disclosed which includes an adjustable knob for indicating the degree of vacuum being applied to the device from a number of incident viewing angles. Similarly, a vacuum indicator assembly is provided for indicating the presence or absence of vacuum being applied to drainage device. The indicator assembly provides an indication of vacuum inside drainage device from many viewing angles and includes a base defining a recess having a slanted surface with a vacuum symbol which is selectively masked by a collapsible thimble when vacuum is applied or removed from the drainage device.

摘要： The present invention provides for a dual port arrangement for a water seal chamber of a drainage device for channeling and restricting fluid flow through the water seal during normal operation of the device when the patient is breathing normally, while preventing the breach of the water seal during reverse flow conditions when the patient takes a sudden and deep inhalation. The dual port arrangement comprises a narrow side port and a low profile tunnel port defining an elongated conduit interposed between and in communication with both arms of the water seal chamber. The side port has a thin slot configuration that restricts fluid flow communication through the side port, and the back tunnel port defines a low profile, elongated conduit with openings that channel fluid flow between both arms of the water seal chamber. The elongated configuration of the conduit prevents a steep water gradient from falling below the upper portion of the conduit opening during reverse flow conditions.
