The present invention relates to an automatic in vitro diagnostic apparatus capable of automatically performing a series of examination processes including a pretreatment process for specific components included in a biological sample such as blood and urine. The apparatus of the present invention comprises a base frame 104; a cuvette tray 110 movable back and forth on the base frame 104, for mounting cuvette holders 10 accommodating a plurality of cuvettes arranged thereon alongside each other; a tube tray 120 movable back and forth on the base frame, for mounting tube holders 20 accommodating a plurality of sample tubes containing samples thereon; and a sampling operation unit 500 movable left and right on the base frame 104, for mixing a sample contained in the sample tube with a reagent, and dropping the mixed solution onto an analysis strip provided in the cuvette.

The present invention provides a detection device comprises a testing element and a transparent area, wherein the testing element comprises a detection area which is configured to detect a presence of an analyte in a liquid sample; the transparent area is configured to read the test result on the detection area through the transparent area; a part of the transparent area contacts a part of the detection area, or the detection area and the transparent area are arranged in one sealed space, thus to make the air in the sealed space not exchange with the air outside the sealed space; the scheme can reduce the mist to ensure the test result is displayed clearly.

Various systems, devices, components, and methods are disclosed for measuring the concentration of an analyte, such as acetone, in a breath sample. The disclosed devices include a breath sample analysis device having a mouthpiece configured to facilitate engagement with a user's mouth to receive a breath sample. The disclosed devices also include a breath sample capture cartridge containing an interactant that extracts the analyte from a breath sample passed through the cartridge. Also disclosed are devices for routing the breath sample through the cartridge during exhalation, and for analyzing a reaction in the cartridge to measure a concentration of the analyte.

The present invention relates to a method of capturing and stabilising volatile thiol malodour generated on the human skin, comprising steps of: i) contacting the human skin with a substrate, ii) absorbing said thiol into the substrate, and iii) reacting said thiol with a thiol-capture agent. The invention also relates to a method of quantifying said thiol, a method of assessing the deodorizing performance of a cosmetic composition on the human skin.

A test strip system having containers and suitable carriers therefor. The test strip assembly is suitable for carrying out different types of chemical, biological or biochemical tests and evaluating them using a suitable analysis device. The test strip assembly has a first region having at least one container and a second region also having at least one container. The container of the first region has a flat transparent bottom, and the container of the second region has a V-shaped or U-shaped bottom.

A toilet for administering a product to a user is disclosed. The toilet includes a bowl, a mechanism for administering the product to the user, a storage structure for storing the product, a sensor that detects a property of the product, and a processor. The bowl is adapted to receiving excreta from the user. The processor compares the detected property with a range of values indicating the suitability of the product for being applied to a user. The processor generates an alert when the detected property falls outside the range of values.

A sensor system includes an electrical circuit having plural leads coupled with one or more sensing regions. The sensing regions include gaps having sensing materials that detect an analyte of interest. The gaps close responsive to the sensing material corresponding to the gaps detecting the analyte of interest. One or more processors communicatively coupled with the electrical circuit receive electrical signals from the electrical circuit indicative of the gaps closing responsive to the sensing material of the corresponding gaps detecting the analyte of interest. The electrical circuit is in a closed position in the presence of the analyte of interest. The sensor system is configured to consume an increased amount of power when the electrical circuit is in the closed position relative to the electrical circuit in an open position responsive to the one or more of the gaps closing. A responsive action is determined based on the electrical signals.

In certain aspects, provided herein are methods and kits for detecting the presence of C. difficile in a biological sample. Also provided herein are methods of selecting of identifying a subject that would benefit from C. difficile treatment.

Disclosed is a sample collection and detection card. A lower cover of the card is provided with a sample loading chamber capable of accommodating a sampling part of a sampling end, an outlet is arranged at a bottom of the sample loading chamber, and a sample loading area of a test strip is located at the outlet; a fixing structure for fixing a sampling rod to a box is further arranged between the box and the sampling rod, and the sampling part is deformable when the sampling rod is fixed to the box. In embodiments of the present disclosure, the sample loading chamber is arranged on the lower cover, and the sample loading area of the test strip is arranged at the outlet of the sample loading chamber.

A device to detect pathogens and/or analytes in a test sample is designed to include a core, which may have first and second chambers. The first chamber is designed to accept a combination of a test specimen and a buffer liquid. A piston is designed to slideably engage into the first chamber of the core, wherein the end of the piston may engage with the bottom of the first chamber and be capable of grinding the test specimen. A plunger is designed to slideably engage with the second chamber of the core, and is in fluid communication with the first chamber. An assay section is attached to the core, and is in fluid communication with the second chamber. The assay device is designed to include a test strip that is capable of detecting and indicating the presence of pathogens and/or analytes in the combination of the test sample and buffer liquid.
