US Patent:

43668160, Jan 4, 1983

Filed:

Dec 22, 1980

Appl. No.:

6/219016

Inventors:

Michael A. Bayard - Chicago IL
James A. Turnbull - Grayslake IL

Assignee:

Abbott Laboratories - North Chicago IL

International Classification:

A61J 700
A61M 100

US Classification:

128213A

Abstract:

A combination quick disconnect coupling and fluid cutoff valve particularly adapted for use in continuous ambulatory peritoneal dialysis comprises a first tubular member connected to a length of flexible tubing and having a fluid passageway therethrough, and a second tubular member connected to a second length of flexible tubing and constructed for telescopic reception of the first tubular member. A rotatable sleeve is disposed within the first tubular member (partially closed at a first end). By rotating the sleeve the fluid passageway may be selectively opened or closed. A coupling mechanism, such as a bayonet lock is used for retaining the first and second tubular members together. A series of lugs extend inwardly from the second tubular member and are arranged to engage the rotatable sleeve as the first tubular member is inserted into the second tubular member, so as to advance the movable sleeve to an open position during coupling thereby opening the fluid passageway. Finally, a resilient sealing mechanism is used for hermetically sealing the connection between the first and second members.

Abstract:

A combination quick disconnect coupling and liquid cutoff valve comprises a first tubular member, and a second tubular member having a cylindrical sheath slidably disposed about and extending therefrom, sized for telescopic insertion into the first tubular member. The first and second tubular members may be coupled together and retained in that position as required. Two fluid passageways extend through the second tubular member. A third tubular member is concentrically positioned within the second tubular member and has a resilient, releasable, penetrable diaphragm at one end. A piercing pin is disposed within the movable cylindrical sheath so that when the piercing pin is exterior to the diaphragm, a first liquid passes through the connector, but when the piercing pin is inserted through the penetrable diaphragm, a second liquid passes through the connector and the flow of the first liquid is shut off.
