US Patent:

7195602, Mar 27, 2007

Filed:

Apr 29, 2004

Appl. No.:

10/834405

Inventors:

Peter A. K. Yong - Torrance CA, US
Mark J. Rispler - Manhattan Beach CA, US

International Classification:

A61B 5/00
B65D 81/00

US Classification:

600573

Abstract:

A dual-chamber device for receiving and containing a liquid, particularly urine, employs a generally cylindrical body having a detachable top cover and an internal, transverse, funnel-shaped wall. The transverse wall has a central circular orifice and divides the body into lower and upper chambers for respectively receiving and retaining fore-stream and mid-stream urine liquid samples. A floatable orifice stopper in the lower chamber is responsive to fore-stream liquid filling the lower chamber to a predetermined level for closing the orifice, so that subsequent, mid-stream urine liquid is received into the upper chamber. An annular float beneath the orifice stopper assures proper stopper closing of the orifice. A bottom cover has an upstanding stopper pushing column and a flexible, spring-like, annular web adjacent the cover periphery. When the urine liquid has been collected in the device and the device is pushed downwardly onto the bottom cover, the web flexes, causing the bottom cover column to force the stopper tightly into the orifice, and locks over center to positively lock the stopper into the orifice to prevent leakage between the two chambers.

Abstract:

A dual-chamber device for receiving and containing a liquid, particularly urine, employs a generally cylindrical body having a detachable top cover and an internal, transverse, funnel-shaped wall. The transverse wall has a central circular orifice and divides the body into lower and upper chambers for respectively receiving and retaining fore-stream and mid-stream urine liquid samples. A floatable orifice stopper in the lower chamber is responsive to fore-stream liquid filling the lower chamber to a predetermined level for closing the orifice, so that subsequent, mid-stream urine liquid is received into the upper chamber. A bottom cover has an upstanding stopper pushing column and a flexible, spring-like, annular web around a bottom cover pedestal region. When the urine liquid has been collected in the device and the device is pushed downwardly onto the bottom cover pedestal region, the web flexes, causing the bottom cover column to force the stopper tightly into the orifice, and locks over center to positively lock the stopper into the orifice to prevent leakage between the two chambers. A microscopic hole in the device body wall substantially above the predetermined urine level in the lower chamber vents air pressure from the lower chamber when the bottom cover is flexed to force the stopper into the orifice.
