Abstract
Abstract A urine collection device and method for females comprising a cup-shaped receiving chamber provided with a flexible lip on the periphery thereof for sealing around the urethral orifice and a duct section leading to a section of flexible tubing. The flexible tubing which leads to a compressible collection reservoir. A two way anti-back flow mechanism is provided to prevent inadvertent flow of the collected urine out of the reservoir but which upon intentional compression by a user a specimen may be obtained by forcing fluid back through the anti-back flow valve. The receiving chamber and collection reservoir are mounted in a housing of soft absorbent material which is provided with an adhesive strip for securing the collection device to the undergarment of a female.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A urine collection device for use by females which is suitable for collecting urine specimens suitable for laboratory examination comprising: a compressible housing; a receiving chamber positioned within said housing, said receiving chamber including an inlet and an outlet, said inlet having means for sealing around the urethral orifice of a female; a compressible reservoir provided within said housing downstream of said receiving chamber outlet; and two-way valve means downstream of said receiving chamber outlet and upstream of said reservoir for passing urine from said receiving chamber to said reservoir while selectively prohibiting back flow of urine from said reservoir such that upon compression of said housing and correspondingly said reservoir said two-way valve means passes back through said receiving chamber outlet thereby allowing urine in said reservoir to be passed back through said two-way valve means so as to obtain a urine specimen for laboratory examination.
Claim 2
Dependent Claim
147 words
A urine collection device for use by females which is suitable for collecting urine specimens suitable for laboratory examination comprising: a compressible housing; a receiving chamber positioned within said housing, said receiving chamber including an inlet and an outlet, said inlet having means for sealing around the urethral orifice of a female; a compressible reservoir provided within said housing downstream of said receiving chamber outlet; and two-way valve means downstream of said receiving chamber outlet and upstream of said reservoir for passing urine from said receiving chamber to said reservoir while selectively prohibiting back flow of urine from said reservoir such that upon compression of said housing and correspondingly said reservoir said two-way valve means passes back through said receiving chamber outlet thereby allowing urine in said reservoir to be passed back through said two-way valve means so as to obtain a urine specimen for laboratory examination.
Claim 3
Dependent Claim
35 words
A urine collection device according to claim 1 wherein said receiving chamber is cup-shaped and is provided thereof with a flexible lip portion defining said inlet for sealing around the urethral orifice of a female.
Claim 4
Dependent Claim
21 words
A urine collection device according to claim 1 wherein a flexible membrane is provided within said housing for defining said reservoir.
Claim 5
Dependent Claim
21 words
A urine collection device according to claim 1 wherein said housing is formed of a soft absorbent material such as gauze.
Claim 6
Dependent Claim
36 words
A urine collection device according to claim 1 wherein said two-way valve means comprises a section of flexible tubing which seals itself as a result of capillary attraction when selectively prohibiting the back flow of urine.
Claim 7
Dependent Claim
37 words
A urine collection device according to claim 5 wherein said receiving chamber outlet comprises a duct having an outer peripheral surface wherein said section of flexible tubing is sealingly secured to said peripheral surface of said duct.
Claim 8
Dependent Claim
139 words
A process for collecting urine from a female wherein said urine collected is suitable for laboratory examination comprising: providing a housing; positioning a receiving chamber within said housing, said receiving chamber being provided with an inlet for sealing around the urethral orifice of a female and an outlet; positioning a reservoir within said housing downstream of said receiving chamber outlet for receiving urine therefrom; providing two-way urine flow control means downstream of said receiving chamber outlet and upstream of said reservoir for passing urine from said receiving chamber through said receiving chamber outlet to said reservoir while selectively prohibiting back flow of urine from said reservoir; and deforming said reservoir wherein urine in said reservoir is passed back through said two-way urine flow control means to said receiving chamber wherein a urine specimen for a laboratory examination is obtained.
Claim 9
Dependent Claim
139 words
A process for collecting urine from a female wherein said urine collected is suitable for laboratory examination comprising: providing a housing; positioning a receiving chamber within said housing, said receiving chamber being provided with an inlet for sealing around the urethral orifice of a female and an outlet; positioning a reservoir within said housing downstream of said receiving chamber outlet for receiving urine therefrom; providing two-way urine flow control means downstream of said receiving chamber outlet and upstream of said reservoir for passing urine from said receiving chamber through said receiving chamber outlet to said reservoir while selectively prohibiting back flow of urine from said reservoir; and deforming said reservoir wherein urine in said reservoir is passed back through said two-way urine flow control means to said receiving chamber wherein a urine specimen for a laboratory examination is obtained.
Claim 10
Dependent Claim
41 words
A process according to claim 7 including the step of providing a flexible tubing as said two-way urine flow control means wherein said flexible tubing passes back through said outlet for passing urine from said reservoir when said reservoir is deformed.
