Apparatus (2) for testing a liquid specimen, which apparatus (2) comprises: (i) a container (4) for the liquid specimen; (ii) a lid (6) for closing the container (4) after the liquid specimen has been provided in the container (4); (iii) first securing means (8) by which the lid (6) is secured to the container (4); (iv) a test capsule (10) for securing to the lid (6) when the lid (6) is on the container (4); (v) second securing means (12) by which the test capsule (10) is secured to the lid (6); and (vi) a response chart (14) which is operable in response to contact with the liquid specimen, and the apparatus (2) being such that: (vii) the lid has an openable portion (18) which when opened permits a liquid specimen in the container (4) to enter the test capsule (10); (viii) the test capsule (10) has opener means (20) for opening the openable portion on the lid (6) when the test capsule (10) is secured to the lid (6); and (ix) the response chart (14) is inside the test capsule (10) and is contacted by the liquid specimen when the liquid specimen enters the test capsule (10).

A flushable apparatus (10) for testing a liquid specimen such as urine for a condition such as pregnancy. The apparatus includes a pliable sheet (11) that can be secured to the rim of a toilet bowl. The sheet is shaped and dimensioned to cause a flow of urine to impact a testing unit (30) such as a pH indicator patch, a biodegradable immunoassay, a metal organic framework composite containing assay, or a removable, non-flushable chromatographic strip, and to dram excess urine away from the testing unit. The apparatus can be disposed of in a convenient, environmentally responsible way. The testing unit can provide results in a color-coded manner that can be easier to read by inexperienced users.

A sampling device (2220F, 2620, 2720) is provided for concentrating a liquid specimen sample (22), including a filtration assembly (2224F, 2624, 2724) which includes a tubular container (1630, 2030), a filter (60), a filter support (1662, 2362), and an inflatable chamber (2700). The filter support (1662, 2362) defines a support surface on which the filter (60) is removably disposed. The inflatable chamber (2700) includes a flexible wall (2702). An interior of the inflatable chamber (2700) is shaped so as to define a space (2733) having an initial volume. A source of gas (2204) is configured to provide gas (2208) into the space (2733). The filtration assembly (2224F, 2624, 2724) is configured such that providing of the gas (2208) into the space (2733), when the liquid specimen sample (22) is contained in the tubular container (1630, 2030) and the filter (60) is disposed on the support surface, increases the initial volume to an inflated volume, so as to push at least a portion of the liquid specimen sample (22) through the filter (60). Other embodiments are also described.

The design points of the design product: in the shape of the product. 4. The picture or photo that best shows the design points: perspective view.

The invention discloses a helicobacter pylori detector. The helicobacter pylori detector comprises at least one detection structure, the detection structure comprises a detection shell, an adsorption ball, an inner pipe, an outer pipe, a liquid release cavity, an extrusion part and a discharge pipe; one end of the inner tube is fixedly connected with the adsorption ball and is movably accommodated in the outer tube; the adsorption ball is used for adsorbing a liquid specimen, and the extrusion part is used for extruding liquid adsorbed by the adsorption ball; a groove matched with the extrusion part is formed in the liquid release cavity, a discharge part is arranged at the bottom of the groove, and the discharge part is communicated with the discharge pipe; one end of the discharge pipe is fixedly connected with the liquid release cavity; an insertion groove for insertion of the discharge pipe is formed in the detection shell; the insertion groove is communicated with the inclined groove; and helicobacter pylori detection test paper is arranged in the inclined groove.

A drainage bag capable of quantitatively collecting liquid specimens belongs to the technical field of medical instruments, is used for collecting specimens and can quantitatively and automatically stop. According to the technical scheme, a liquid leading-in cylinder is placed in a drainage bag, the upper end of the liquid leading-in cylinder is connected with the periphery of a liquid inlet hole of the drainage bag, the lower end of the liquid leading-in cylinder is closed, small communicating holes are evenly distributed in the bottom face of the liquid leading-in cylinder, positioning scales are arranged on the outer wall of the liquid leading-in cylinder, and the lower portion of a quantitative adjusting pull tube is placed in the liquid leading-in cylinder. The upper portion of the quantitative adjusting pull tube is connected with the lower end of the drainage hose, the hollow piston is installed at the lower end of the quantitative adjusting pull tube, the outer wall of the hollow piston is in tight sliding fit with the inner hole wall of the liquid introduction cylinder, the closed floating ball is placed below the hollow piston, and the diameter of the closed floating ball is larger than that of a center through hole of the hollow piston. The quantitative liquid sample collector is simple in structure and convenient to use, liquid samples can be quantitatively collected, the work of staring and controlling the drainage amount is relieved, and the risk of excessive drainage easily caused is avoided.
