Stereotaxic turntable multi-item dry fluorescence detector

Abstract

The invention discloses a three-dimensional positioning turntable multi-item dry-type fluorescence detector, which includes a mounting plate, a test card carrying plate, a card dial device, a card feeding device, a card reading detection device, a card taking device, a card pressing device and Card clamping device; the mounting plate is fixedly set, the test card carrying plate is fixed under the mounting plate, the card dialing device is rotated and stacked on the test card carrying plate, and a card slot for preventing the test card from sliding is formed on the test card carrying plate; The card feeding device radially transports the test card to the card slot; the card reading detection device moves radially to detect the test card; the test card carrying plate is provided with a baffle for preventing the test card from slipping out of the card slot; The test card is pressed down; the card clamping device clamps and straightens the test card from both sides of the test card before the card reading detection device detects; the card taking device sends the test card out of the card slot along the radial direction. The detector can avoid detection errors and improve the reliability and stability of the detector.

Description

technical field [0001] The invention relates to the field of medical detection instruments, in particular to a stereotaxic turntable multi-item dry fluorescence detector. Background technique [0002] Dry fluorescence detection technology is a rapid medical detection technology that has emerged in recent years. This technology is based on a dry fluorescence test card as a carrier, and is used for rapid medical detection through the combination of measurement optical path, barcode reader and test platform. a detection technique. [0003] Dry fluorescence detection technology is an analytical technique developed based on the principle of fluorescent immunoassay for quantitative or qualitative analysis of the substances contained in the test sample. Reaction to form a conjugate, which emits a specific spectrum of emission fluorescence under the excitation of a specific wavelength of excitation light. The emission light is proportional to the analyte. By testing the fluorescenc...

Problems solved by technology

When the card reading detection device scans and detects the test card in the radial direction, due to the slight bending deformation of the test card, the incident angle of the test light source of the card reading detection device is the same, and it is irradiated on the plane with different angles, which will cause its The angle of reflected fluorescence is shifted. If the measured surface of the test card is not level, the finally collected reflected light intensity value will not meet the test requirements.
