ASSAY APPARATUS AND CARTRIDGE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18466099 titled 'ASSAY APPARATUS AND CARTRIDGE

Simplified Explanation

The patent application describes an assay apparatus used for an immunochromatographic assay.

  • The apparatus includes an illumination unit that emits light to illuminate an observation region, including an assay region.
  • The color development state in the assay region changes depending on whether the sample is positive or negative.
  • The illumination unit can be brought into contact with the outer shell of the cartridge in a loaded state.
  • The emission end portion of the illumination unit is separated from the opening portion on the outer surface of the outer shell.
  • The separated position guides the incident light from the emission end portion to the inner edge of the opening portion by transmitting the light through the outer shell.

Potential applications of this technology:

  • Immunochromatographic assays in medical diagnostics.
  • Point-of-care testing for rapid and accurate detection of diseases.
  • Environmental monitoring for detecting contaminants or pathogens.

Problems solved by this technology:

  • Provides a simplified and efficient assay apparatus for immunochromatographic assays.
  • Allows for easy illumination of the assay region to observe color development.
  • Prevents interference from external light sources.

Benefits of this technology:

  • Improved accuracy and reliability of immunochromatographic assays.
  • Simplified design and operation of the assay apparatus.
  • Enhanced portability and ease of use for point-of-care testing.


Original Abstract Submitted

An assay apparatus used for an immunochromatographic assay, the assay apparatus comprising an illumination unit that has an emission end portion for emitting light that illuminates an observation region including an assay region in which a color development state changes depending on whether a sample is positive or negative, where the illumination unit makes it possible to dispose at least a part of the emission end portion, in a state of being brought into contact, in a position separated from an opening portion on an outer surface of the outer shell of the cartridge in a loaded state, the position being capable of guiding a light incident into the outer shell from the emission end portion to an inner edge of the opening portion by transmitting the incident light through the outer shell.
