Abstract

Provided in the present invention is a reference cassette for a fluorescence immunoassay diagnostic device, the cassette having, arranged in a case, fluorescent glass capable of maintaining fluorescence characteristics to be constant without causing degeneration, so as to accurately provide reference measurement information about the fluorescence detection amount during testing of the measurement accuracy of the fluorescence detection of the immunoassay diagnostic device, so that testing accuracy can improve, preventing decrease in measurement accuracy and being semi-permanently usable since the denaturation or deterioration of the fluorescent glass does not occur even if the cassette is used continuously, and providing a mask having a slit so as to limit the area of the fluorescent glass to be externally exposed to a specific area, thereby generating the type of fluorescence that is the same as that of a reaction area of a sample strip to be actually used, and thus more accurate reference measurement information can be provided.

Core Innovation

A reference cassette for a fluorescence immunoassay diagnostic apparatus is configured to be inserted into the apparatus, and the apparatus diagnoses a disease from a biopsy specimen using fluorescence. The reference cassette generates fluorescence by a test light of an optical module and includes a case configured to be insertable into the fluorescence immunoassay diagnostic apparatus. An opening is formed at at least a part of an upper side of the case so that an inner space of the case is exposed to an outside of the case, and fluorescence glass is disposed in the inner space of the case so that the fluorescence glass is exposed to the outside of the case through the opening of the case.

The fluorescence glass is configured to generate the fluorescence by the test light of the optical module and constantly maintain fluorescence characteristics. A mask is disposed on an upper surface of the fluorescence glass inside the case so that an area of the fluorescence glass exposed to the outside of the case is limited to a specific area of the fluorescence glass. The mask has one or more slits, and the fluorescence glass is exposed through the slits, so that the slit areas define an outside exposure area of the fluorescence glass.

A separate fixing guide having a plurality of insertion coupling holes is coupled to the inside of the case, and the fluorescence glass includes a plurality of pieces of the fluorescence glass. Each piece of the fluorescence glass is insertedly coupled to a respective insertion coupling hole of the fixing guide, and the mask is coupled to the fixing guide so that each of the slits limits an outside exposure area of the fluorescence glass to a slit area. The upper surface of the fluorescence glass and an upper surface of the fixing guide are in a same plane as each other, and the mask is coupled to the fixing guide to contact the upper surface of the fluorescence glass and the upper surface of the fixing guide.

Claims Coverage

The document contains one independent claim, with additional refinements in dependent claims. The independent claim covers a structured reference cassette with four inventive features.

Overall, the claim coverage centers on a reference cassette in which fluorescence glass exposed through a case opening generates fluorescence while constantly maintaining fluorescence characteristics, a mask with slits limits the exposed area to a slit-based outside exposure area, and a fixing guide with insertion coupling holes positions multiple pieces while maintaining co-planar upper surfaces and mask contact.
