  • Patent number: 11131662
    Abstract: A detection device for detecting analytes in liquid specimen is provided. The detection device comprises: a specimen chamber for collecting or storing a liquid specimen; a detecting chamber for containing a detecting element; and a through hole for transferring the liquid specimen between the specimen chamber and the detecting chamber. The through hole can be opened or self-sealed. The sealing or opening of the through hole controls whether or not the liquid specimen in the specimen chamber enters the detecting chamber via the through hole. Furthermore, a detection method is provided.

  • Publication number: 20130242308
    Abstract: A device for reading an assay test result on a test carrier comprises: a light-emitting element (5) for emitting and irradiating light onto corresponding one or more zones of the test carrier (3); a light-blocking element (12) for blocking the light mirror-reflected by the test carrier (3) from being irradiated on a photodetector (7); and a window (10), through which the light emitted from the light-emitting element (5) is irradiated onto the corresponding zones of the test carrier (3). In one preferred embodiment, the positions of the light-emitting element (5), the light-blocking element and the window (10) meet the function of S3?>2*S7?S7*S2/S1, where S1 represents the vertical distance between the light-emitting element and the window; S2 represents the vertical height of the light-blocking element; S3 represents the vertical distance between the light-blocking element and the light-emitting element; and S7 represents the length of the window.
