Abstract
Abstract A device useful in medical laboratories for receiving urine and performing analyses thereof is described. In a preferred embodiment urine flows into portions on either side of a unitary housing. The two side portions are interconnected by an overflow reservoir. Urine first fills a plurality of upper compartments having preselected volume and then overflows a weir into the reservoir. In the other side portion a trough receives urine and wicks transfer a limited quantity thereof to nutrient media. A special sample tube in the second side portion collects urine for sedimentation analysis. Excess urine overflows to the reservoir. A float in the reservoir closes off the weirs when the reservoir is filled. A slide in the first side portion is then removed to permit urine to flow from the upper compartments to lower compartments each of which contains an analysis reagent. An inner housing within the second side portion with nutrient media is removable for incubation. In another embodiment, urine is collected in a compartment that can be closed off by a float. At any convenient time thereafter a wall of the compartment can be ruptured to permit the urine to flow into a second compartment where a test reagent provides a urine analysis. In still another embodiment the patient urinates into a receiving vessel having side apertures near its bottom and mounted on a float. Initially, the urine flows from one aperture to a region beneath the float. After the float rises to a certain extent, the first aperture is occulted and urine overflows through a second aperture into a sample chamber. Thus, a midstream sample is obtained in the sample chamber.
