Semi-automatic microcolumn gelatin card detection system and detection method

Abstract

The invention discloses a semi-automatic microcolumn gelatin card detection system and detection method. The semi-automatic microcolumn gelatin card detection system comprises a computer provided with a background software system and a host, wherein the computer is connected with the host through a USB, a network port or series port; a master control unit, an incubation unit, a centrifugal unit, a code scanning unit, an image collection unit and a card holder are arranged in the host; the master control unit is connected with the incubation unit and the centrifugal unit through an industrial control bus; the master control unit is connected with the code scanning unit and the image collection unit through the USB; and the card holder comprises a gelatin card holder for storing a gelatin card for detection and a sample adding position carrier for placing the gelatin card during sample adding. Hybrid detection of multiple gelatin cards is supported. Compared with a full-automatic detection system, the time of the whole operation process is shortened, and the requirements of emergency priority are met; the detection result is permanently stored, sharing and tracing are facilitated and the comprehensive electronic information requirements of medical institutions are met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a semi-automatic micro-column gel card detection system and detection method. Background technique [0002] Microcolumn gel card detection is a method commonly used in clinical blood testing in medical institutions. The essence of the technology is the hemagglutination experiment, that is, the visible immunoagglutination reaction of the red blood cell antigen antibody in the gel medium in the microcolumn cavity. When the antigen-antibody reaction causes red blood cells to agglutinate, after the micro-column gel card is centrifuged by a centrifuge, the agglutination cannot pass through the gap of the gel and remains on the upper layer of the gel in the micro-column cavity, showing a positive reaction; when the antigen-antibody If there is no reaction, the red blood cells will not agglutinate. After being centrifuged by the centrifuge, the red blood cells can reach the bot...

Problems solved by technology

At present, there are fully automatic detection systems on the market that can automatically complete such operations and result interpretation, but the existing automatic detection systems mainly have the following technical problems: (1) Since the gel card is opened by mechanical puncture, it is also limited by the fixation method. The size of the mechanical gripper cannot support the mixed detection process of gel cards of different sizes; (2) It is necessary for the operator to add the prepared sample to be tested into a specific container matching the automatic detection system. The automatic detection system only realizes the The function of adding samples from a specific container to the micro-column gel card does not save the operator's work process of adding samples, but instead increases the time of the entire operation process due to the secondary addition of samples; (3) The automatic detection system does An experiment cannot be interrupted once it starts, and it takes a long time to process a batch of micro-column gel cards, which cannot meet the requirements of clinical emergency patients for follow-up inspection; (4) After the test is completed, the gel cards are automatically discarded to the garbage barrel, does not support manual proofreading of test results in the later stage of testing; (5) The design and structure of the fully automatic testing system is complex and expensive, and it is not suitable for clinical use in small and medium-sized medical institutions
