The present disclosure relates to a method of manufacturing a microfluidic device, which may precisely form a channel having a desired shape within one substrate using a wax regardless of a shape of a hydrophilic porous substrate, and more specifically, to a method of manufacturing a microfluidic device in which a microchannel is formed by a wax within one hydrophilic porous substrate, the method including: an operation of stacking and then heat-treating a transfer film on which a mirror image of a wax pattern is formed to form a microchannel and the substrate.

In one configuration, a handheld compound tester to process and detect presence of a compound in a tablet is disclosed. The handheld compound tester may include a sampling chamber configured to receive a tablet and a lid couplable with the sampling chamber. The coupling of the lid with the sampling chamber may cause cutting of the tablet. A liquid may be added inside the sampling chamber to create a mixture with segments of the tablet. The mixture may be then received by a housing adjoining the sampling chamber. A test strip disposed within the housing, upon contacting the mixture, may be configured to indicate a presence of the compound in the mixture.

A hand-held applicator (10) for collecting, mixing, diluting and discharging a sample liquid, comprising a main body (20) having an inlet-aperture (24), an outlet-aperture (26) and a chamber (22) for storing a liquid solution, wherein the chamber is connected to the inlet-aperture and the outlet-aperture, a lid (12) for covering the inlet-aperture and a tube (40), moveably supported in the inlet-aperture when the lid is covering the upper portion of the main body, wherein the tube (40) is moveable between a predetermined position outside the chamber and a position, in which the tube is at least partly located in the chamber.

The present invention relates to a transfer platform for a biological sample analyzer, comprising a movable carrier plate and an object stage which is placed on the carrier plate and separable from the carrier plate. The side of the carrier plate facing the object stage is an upper surface, and the reverse side is a lower surface. The side of the object stage facing the carrier plate is a lower surface, and the reverse side is an upper surface. The object stage and the carrier plate are respectively provided with magnetic blocks that magnetically attract each other. When the object stage is placed in a predetermined area on the carrier plate, the suction of the magnetic blocks automatically positions the object stage relative to the carrier plate, thereby achieving the technical effect of blind positioning. The present invention can be applied to test analyzers for specific proteins, cholesterol, heme, routine urine test, dry biochemical test, etc. The present invention has the advantages of convenient operation, time and effort saving, high efficiency and the like. Meanwhile, the present invention is simple in structure and low in cost, and is suitable for wide promotion.

A device for processing a sample comprises a blister defined by first and second walls. The first wall is flexible allowing the blister to be divided into one or more sealed regions by an external pressure applied to a portion of the first wall. The external pressure is applied in the form of a 2-dimensional shape to form a sealed region having that shape.

A moisture-tight, re-sealable container is disclosed having a lid and body. The lid and body have a non-round seal that is substantially moisture tight when the lid is seated on the body, admitting less than 1000 micrograms per day of water to a package. A reinforcement stiffens or reinforces at least a portion of the seal against inward deflection along an axis defined by the minor diameter when the lid is seated on the body. Optionally the reinforcement is at least one spline subdividing the reservoir. A method of making dispensers for objects of varying length to customize particular dispensers to dispense such objects of a particular length is also disclosed.

The present invention provides an apparatus for detecting the presence or absence of an analyte in liquid sample, including: a collection chamber, including an opening for collecting a liquid sample; a testing element for testing the analyte in liquid sample; and a cover for covering the opening of the collection chamber; wherein the apparatus further includes a prompting device for prompting if the cover is covered to a specified location, and the prompting device shall at least includes a first element and a second element, the first element is in contact with the second element, wherein one element vibrates to produce a sound. In some preferred ways, the second element produces friction with the first element, to cause one of the elements to generate vibrations. The apparatus in the present invention can allow the prompting sound to be clear and loud.

A method of determining concentration of an analyte in a body fluid uses a mobile device having a camera and an ambient light detector. The ambient light detector has an ambient light sensor and/or an additional camera. An ambient light check is performed. In the ambient light check, ambient light is used to determine an item of ambient light information. If a validity criterion is determined to be met, the concentration of the analyte is determined by evaluating an image of at least a part of a reagent test region of an optical test strip having a sample of body fluid applied thereto. The image is captured by the camera. A mobile device, a kit, a computer program and a computer-readable storage medium are also disclosed.

A device for performing an assay comprises a tube, a cap, an insert, and a reaction container. The tube includes a lateral flow strip disposed therein. The cap is coupled to the tube and includes a hollow interior defined at least partially therethrough. The insert is configured to be at least partially received within the hollow interior of the cap. The reaction container includes a cavity configured to store one or more fluids therein, and is rotatably coupled to the cap such that rotation of the cap relative to the reaction container causes (i) mixing of the one or more fluids and (ii) at least a portion of the mixed fluids to be delivered from the reaction container to the lateral flow strip via the insert.

It is an object of the present invention to provide improved lateral flow test devices that can provide sensitive and accurate quantitative test results, and methods for the manufacture thereof.
