    摘要： The liquid sample capture apparatus captures a sample of a liquid and holds the sample for optical analysis. The apparatus may include a mount which is traversed by a sample conduit. The mount may have an elongated shape and two ferrules may be placed within the mount along the longitudinal axis of the mount. An end of each of the ferrules may extend into the sample conduit forming a narrowing of the sample conduit which holds the liquid and prevents it from escaping prior to analysis. The opposite ends of the ferrules may each be connected to an optical cable. The optical cables may be connected to an analytical device, for example, a spectrometer. The apparatus may be mounted within a toilet bowl where it may capture and analyze a urine sample.

    摘要： A specimen collection receptacle formed by a channel disposed within the wall of a toilet bowl. The receptacle is located above the weir water line. The receptacle comprises a channel open to the interior of the bowl having opposed non-parallel side walls. The side walls may be joined opposite the opening. The side walls may be joined by a bottom wall. The bottom wall may be arcuate. The side walls may be non-planar. The walls may exhibit a roughened surface. The receptacle may comprise an optical window. The receptacle may comprise a cuvette. The receptacle may be in communication with one or more light emitting probes. The receptacle may be self-cleaning. The receptacle may comprise a replaceable module disposed in the wall of the toilet bowl. The receptacle may be located at the front of the toilet bowl. The receptacle may be disposed in a toilet bowl liner or insert.

    摘要： A urinalysis cassette and system that includes a toilet, into which a urinalysis cassette is inserted. The cassette is comprised of a roll of color-change-reagent strips. Each strip includes a plurality of strip sections wherein an absorbent material is imbued with color-change reagent, or onto which one or more color-change reagents are dispensed. The color-change-reagent strips are consecutive and contiguous on the roll. A cassette includes two spools arranged such that when the spools turn, the reagent strip moves from a first (source spool) to a second (waste spool). The section of the reagent strip that is between the two spools may be exposed to a urine specimen. The absorbent-material strips that have been exposed to both a urine specimen and a color-change reagent may undergo a chemical reaction. Selective-lighting illumination may be applied to absorbent-material strips that have undergone such chemical reactions to measure reflectivity of certain color wavelengths. This measurement may be expressed in terms of a digital readout, which may be displayed on a user interface.

    摘要： A helical drain for a toilet is disclosed. The present invention relates to a novel toilet drain configuration. Specifically, the novel toilet drain configuration comprises a helical loop trapway. The drain of the present invention exits the toilet bowl and forms a substantially vertical tubular loop running generally parallel to the width of the bowl or stool, or perpendicular to the longitudinal axis of the bowl or stool, before being connected to a sewer. The drain of the present invention functions like a P-trap syphon in removing the contents of the bowl. The diameter of the looped tubular portion of the drain may vary by approximately 20 percent or less in the direction of the sewer connection. Sensors may be placed on the drain to monitor drain contents, fluid levels, and drain performance. The drain may be fitted with valves to control the flow of fluids and gases through the drain.
