Inventor(s): Dunn; William J. (Libertyville, IL)
Assignee: The Kendall Company (Boston, MA)
Application Number:06/139,320
Patent Claims: 1. A liquid receptor, comprising:

a receptacle having a chamber to receive body liquids; and

means for selectively emptying the receptacle chamber comprising, a valve assembly attached to the receptacle having a hollow housing with a channel and a front opening communicating with the channel, an elongated tube of elastic material having one end communicating with the receptacle chamber and extending through the housing channel, with the other end of the tube being open adjacent the housing and communicating with the atmosphere, a valve element slidably received in the housing opening, said valve element having an outer portion located outside the housing, an inner portion defining an aperture extending through the valve element to receive said tube, and a rear portion adjacent a rear part of the aperture, said valve element being movable between a first position with the rear portion of the valve element spaced from a forward wall portion of the housing such that said tube is open between the valve element rear portion and the housing forward wall portion to permit passage of liquid through the tube, and a second position with the rear portion of the valve element located adjacent an inner part of the forward wall portion to reduce the size of the valve element aperture in the channel and close said tube by squeezing the tube between the valve element rear portion and the housing forward wall portion to prevent passage of liquid through the tube, and means for biasing the valve element from said first position to said second position, the biasing means comprising a helical spring extending between the rear portion of the valve element and a rear wall of the housing.

2. The receptor of claim 1 including a pair of pins extending from the rear wall and rear portion, said pins being received in opposed ends of said spring.

3. The receptor of claim 1 wherein the forward wall portion of the housing comprises a pair of generally aligned spaced plates extending inwardly from a front wall of the housing and defining an inner portion of said opening communicating with the channel.

4. The receptor of claim 1 including a hollow retaining member attached to an upper portion of the housing, said retaining member having a lower tubular section received inside an upper portion of said tube, and said retaining member communicating with the receptacle chamber.

5. The receptor of claim 4 wherein said tubular section is elongated in lateral cross-section.

6. The receptor of claim 1 wherein said housing includes a pair of spaced lower inner plates engaging opposed sides of said tube.
