Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to overcome the problem that the common photosensitive components in the prior art cannot obtain the complete detection area image within the short-distance focus range, and the instrument structure is too large to be hand-held and portable, a portable Immunochromatography analyzer, through two mirror reflections, the direct distance between the imaging sensor and the detection card is 2-6cm, and finally the imaging sensor can obtain effective image information of the entire detection area, so that the thickness of the entire instrument is reduced, which truly reflects the POCT detection Handheld and portable features

Abstract

The invention relates to the technical field of immunologic diagnosis instruments, and particularly relates to a portable immune-chromatography analysis meter. The portable immune-chromatography analysis meter comprises a detection card fixing device, a large reflective mirror used for reflecting a detection area, a small reflective mirror used for reflecting a detection area image formed in the large reflective mirror, and an imaging sensor used for capturing the detection area image reflected by the small reflective mirror. According to the portable immune-chromatography analysis meter disclosed by the invention, effective image information of the overall detection area can be finally captured by the imaging sensor through two times of mirror reflection under a condition that the direct distance between the imaging sensor and the detection card is 2-6 cm, so that the thickness of the overall instrument is reduced, and the characteristic that POCT (Point Of Care Testing) detection is handheld and portable is reflected; an LED (Light-Emitting Diode) light source unit is arranged inside a shell of the diagnosis instrument, and the light emitted from the LED light source unit can be uniformly distributed on a detection card arranged in the fixing device, thus an effective image of the detection area can be rapidly captured by the imaging sensor.

Description

technical field [0001] The invention relates to the technical field of immunodiagnostic instruments, in particular to a portable immunochromatography analyzer. Background technique [0002] Immunochromatography test card detection technology is widely used in various fields of POCT rapid detection. The reagents to be detected are colloidal gold, latex, immunofluorescence reagents, etc. During the detection, the sample detection information is obtained by taking the image or color of the collected sample after detection. The samples to be tested are extensive, and can be human or animal body fluids, such as blood, urine, etc., or cell or tissue samples. It is characterized by immobilizing a specific antibody on a certain zone of the nitrocellulose membrane of the chromatographic card. When the zone touches the reaction sample (urine, or serum), the antibody will specifically bind, and the zone will display a certain color. , the depth of the color is proportional to the conc...
