Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of reagent detection, and in particular relates to a detection card shell device. Background Art
[0002] Cross-linked antibody blockers are mainly used for immunoassays in in vitro diagnosis. Methodologies include enzyme immunoassay, chemiluminescence, colloidal gold, fluorescence chromatography, etc., among which colloidal gold and fluorescence chromatography both use chromatography test strips. Conventional operations are to fix the test strips in the cartridge after preparation to make a test card, dry and seal it for storage, take out the test card when in use, and complete the sample addition test through the sample addition hole on the cartridge. However, since the sample addition port and the result observation port are open, the cartridge sealing effect is poor and it is easy to get damp. External pollutants can easily enter the cartridge of the test paper and cause contamination. Often, only after adding the sample, when the result observation port shows that the test strip is invalid, can it be found that the test strip has been damp, and it is necessary to resample and test, which brings great inconvenience in actual work, causes waste of raw materials, and increases the cost of testing. In addition, when handling the used test strip, the open sample addition port may cause the sample to spill, causing leakage and polluting the environment. In view of this, it is necessary to study a test card cartridge device. Summary of the invention

DETAILED DESCRIPTION
[0016] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] See also Figures 1 to 3 The utility model discloses a detection card shell device, comprising a main body 1, a dropper 2, a transparent protective cover 3 and a flip cover 4. A test strip is arranged inside the main body 1, and a sample addition port 1.1 and an observation port 1.2 corresponding to the test strip are arranged on the upper part of the main body 1. The transparent protective cover 3 is arranged above the sample addition port 1.1 and the observation port 1.2, and the sample addition port and the observation port 1.2 are bucket-shaped structures.
[0018] The outer periphery of the transparent protective cover 3 is provided with a fixing assembly fixed to the main body 1, and the fixing assembly includes side fixing strips 5 respectively provided on both sides of the transparent protective cover 3 and a rear fixing strip 6 connecting the tail ends of the two side fixing strips 5. Turning strips 3.1 are vertically provided on both sides and below the rear end of the transparent protective cover 3. The bottom inner sides of the side fixing strips 5 and the rear fixing strips 6 are provided with a slide groove 5.1 matching the turning strip 3.1. The turning strip 3.1 is correspondingly inserted into the slide groove 5.1 and moves in the slide groove 5.1 until the transparent protective cover 3 is fixed. Samples can be added by pulling out a part of the transparent protective cover 3 to prevent the reagent from dripping onto the observation port 1.2. After the sample addition is completed, the transparent protective cover 3 can be pushed back to avoid contamination during the process of waiting for the observation results.
