A test method for determining adulteration by diuresis or the addition of a diuretic, which uses creatinine and specific gravity measurements to determine a normalized creatinine value for comparison with expected normalized creatinine values for the substantially diuretic-free population.

A bag made of two layers of film material welded together along their edges except at an aperture in which is inserted one end of a tube of the same material as the bag, the entire circumference of said tube being tightly sealed to the sides of the bag aperture by heat welding.

A urine metering and collection system is disclosed which includes a relatively stiff integral head member having a volume calibrated chamber with sidewalls continuously converging downwardly towards each other such that each horizontal section of the chamber has a smaller volume per unit of height than does the next adjacent upper horizontal section throughout a major portion of the length of the chamber, an outlet passageway adjacent the bottom of the chamber, an inlet passageway adjacent the ...

A sterile midstream urine collector having an open-ended tubular body and a cup mounted therein, the cup having its open top equipped with a cover that is formed at least in part of a water-soluble material. During use of the device, the cover initially deflects a stream of urine flowing through the collector and within seconds dissolves sufficiently to allow a subsequent uncontaminated portion of the stream to enter the cup. A sample evacuation passage extends from the cup and communicates, or ...

A patient-care system is disclosed comprising a container housing a device that delivers an agent for controlling the presence of pathogens. Also, the device and a method are disclosed using the device for preventing pathogenic infections.

A urine specimen collection system wherein a collection funnel and attached collection lid are first releasably connected to a specimen cup by structure of a first peripheral connection between the collection lid and the cup; and then after a urine specimen has been collected this first connection is released and a storage lid is releasably connected to the cup by structure of a second peripheral connection. The first connection is more easily releasable than the second one, and need not be wate...

A container, which is flat in its empty condition, of plastic, rubber or another flexible material, especially for the collection of urine and/or faeces. The container comprises two outer walls (2) joined together in a surrounding seam (6), an inlet (54) and, if desired, an outlet (58). The inlet is provided with a non-return valve formed by enveloping a tube end (76) in two intermediate layers having the same extent as the outer walls (2) in the width direction of the container, the intermediat...

A disposable urine bag having sealed cavity members where one cavity stores an extendable catheter and also acts as a urine storage reservoir. A second sealed and peel-away cavity includes a catheter advancement mechanism which provides for lubricated catheter advancement without actual contact of the catheter by the human hand. An absorption member is provided to semi-solidify urine stored in the urine storage reservoir.

A device for collecting uncontaminated urine specimens from adult females, adult uncircumcised males and pediatric males. The device includes an elongated flexible tubular conduit member having a funnel-shaped opening at one end to be in sealing relationship with a urethra or glans penis and a discharge end to be received within a sample container. The sample container includes an opening with sealing means therein to receive the discharge end of the elongated flexible tubular conduit member in ...

A method of detecting gluteraldehyde adulterant in a urine sample. An aliquot of urine is inserted into an automatic chemical analyzer and a spectrophotometric absorbance reading is taken. Thereafter, the aliquot is mixed with a reagent mixture containing a carbonyl indicator and a second spectrophotometric absorbance reading is taken and compared to the first reading.
