Abstract
A device for detecting an analyte in a sample is provided, which comprises: a collecting chamber containing an opening for collecting a liquid sample; a detecting element for detecting an analyte in the liquid sample; and a lid for covering the opening of the collecting chamber. The device further comprises an indicating device thereon to indicate whether or not the lid covers at an appointed position. The operation of the device is very simple.
Core Innovation
The invention relates to a device for detecting an analyte in a liquid sample. The device includes a collecting chamber having an opening for collecting the liquid sample and external screw threads proximate the opening, and a detecting chamber having a detecting element for detecting the analyte in the liquid sample. A lid covers the opening of the collecting chamber and includes internal screw threads rotationally engaging the external screw threads to close the collecting chamber.
The device further includes an indicating device configured to indicate whether the lid covers the opening at an appointed position at which a liquid tight seal of the opening is formed when the lid and the collecting chamber are rotated relative to each other. The indicating device generates a knocking sound when the lid covers the opening at the appointed position, and the knocking sound results from elastic deformation and rebound of an elastic element disposed on the collecting chamber upon interaction with a non-elastic element disposed on the outer surface of the lid edge.
The knocking sound indicates formation of the liquid tight seal of the opening and the start of a detection assay by the detecting element when in use. A detection result is displayed on the detecting element after an allotted time starting from the generation of the sound. The disclosed arrangement includes elastic and non-elastic elements in rotatable engagement with the internal and external screw threads.
Claims Coverage
Independent claim 1 provides the main inventive concept and contains 4 inventive features: a lid-closure mechanism, a knocking-sound indicating device, a timed assay initiation and display, and rotatable screw-thread engagement with elastic deformation geometry.
Knocking-sound indicating liquid-tight sealing at an appointed position
An indicating device indicates whether the lid covers the opening at an appointed position at which a liquid tight seal of the opening is formed when the lid and the collecting chamber are rotated relative to each other, and generates a knocking sound when the lid covers the opening at the appointed position.
Elastic and non-elastic interaction producing knocking sound during lid rotation
The indicating device comprises an elastic element disposed on the collecting chamber and a non-elastic element disposed on the outer surface of the lid edge; the knocking sound results from elastic deformation and rebound of the elastic element upon interaction with the non-elastic element during rotation.
Timed assay initiation and display tied to sound generation
The knocking sound indicates formation of the liquid tight seal of the opening and the start of a detection assay by the detecting element when in use, and a detection result is displayed on the detecting element after an allotted time starting from the generation of the sound.
Rotatable screw-thread engagement with elastic deformation geometry
The lid includes internal screw threads rotationally engaging the external screw threads, and the elastic element and the non-elastic element are in rotatable engagement with the internal and external screw threads.
Overall, the independent claim ties together a lid-closure mechanism using internal and external screw threads, an indicating device that produces a knocking sound via elastic deformation and rebound of an elastic element interacting with a non-elastic element, and assay timing where the sound indicates seal formation and assay start and the detection result is displayed after an allotted time.
Stated Advantages
Generates a knocking sound to indicate formation of a liquid tight seal of the opening and the start of a detection assay.
Enables displaying a detection result on the detecting element after an allotted time starting from the generation of the sound.
Documented Applications
Use as an analyte-detection device for liquid samples, including bodily fluids such as urine and saliva, where a collecting chamber and detecting element are used for analyte detection.
