Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a reagent rack for a full-automatic blood type analyzer. Background Art

[0002] The full-automatic blood type analyzer is mainly used to complete experiments such as ABO, Rh (D) blood type and irregular antibody screening, and cross-matching. From sample scanning, reagent card loading, puncture, sample addition, dilution, reagent addition, incubation, centrifugation, to result interpretation, all are automatically completed without manual intervention.

[0003] For example, a full-automatic blood type analyzer with the patent number 202323402189.0 has a reagent rack on its workbench. The reagent rack is used to place reagent tubes. Multiple sampling needles of the sampling arm extend into each reagent tube in parallel to suck the reagent liquid and distribute the reagent liquid onto the microplate, saving the reagent distribution time and avoiding reagent cross-contamination. The test tube rack of such a full-automatic blood type analyzer usually needs to fix the reagent tubes to prevent the reagent tubes from shaking and improve the accuracy of reagent addition. The existing reagent rack fixes the reagent tubes through elastic pieces, but most of the elastic pieces are built into the test tube holes, which is not conducive to disassembly and assembly. Therefore, there is an urgent need to produce a reagent rack for a full-automatic blood type analyzer with a simple structure, easy disassembly and assembly, and can effectively prevent the reagent tubes from shaking. Summary of the Utility Model

The upper surface of the rack body is provided with an installation groove corresponding to the installation part. The installation groove communicates with the test tube hole. Installation holes corresponding to the screws are arranged in the installation groove. The installation part is horizontally arranged. The installation part symmetrically connects the two deformation parts. The deformation parts vertically extend into the test tube holes.

[0007] Preferably, the deformation part includes a vertical connection section and a V-shaped deformation section connected in sequence. The vertical connection section is perpendicular to the installation part, and the vertical connection section and the installation part are in arc transition.

[0019] See Figures 1-4, the present utility model relates to a reagent rack for a full-automatic blood type analyzer, which includes a rack body 1 and a spring piece 2. The rack body 1 is provided with a plurality of test tube holes 1.1 for accommodating reagent tubes in an array. A spring piece 2 is arranged in the test tube hole 1.1. The spring piece 2 is fixed on the upper surface of the rack body 1 by screws 3. The spring piece 2 is integrally formed by a sheet metal part. The spring piece 2 includes a mounting part 2.1 and two deformation parts 2.2. The upper surface of the rack body 1 is provided with a mounting groove 1.2 corresponding to the mounting part 2.1. The mounting groove 1.2 communicates with the test tube hole 1.1. Mounting holes 1.3 corresponding to the screws 3 are provided in the mounting groove 1.2. There are two mounting holes 1.3. The mounting part 2.1 is horizontally arranged. The mounting part 2.1 symmetrically connects the two deformation parts 2.2. The deformation part 2.2 vertically extends into the test tube hole 1.1. The deformation part 2.2 includes a vertical connection section 2.2.1 and a V-shaped deformation section 2.2.2 connected in sequence. The vertical connection section 2.2.1 is perpendicular to the mounting part 2.1, and the vertical connection section 2.2.1 and the mounting part 2.1 are in arc transition. The vertical connection section 2.2.1 fits against the inner wall of the test tube hole 1.1. The reagent tube inserted into the test tube hole 1.1 is fixed by being squeezed by the V-shaped deformation section 2.2.2.

[0020] The bottom of the V-shaped groove of the V-shaped deformation section 2.2.2 is in arc transition. When a reagent tube (not shown in the figure) is inserted into the test tube hole 1.1, the bottom of the V-shaped groove of the V-shaped deformation section 2.2.2 contacts the reagent tube. The V-shaped deformation section 2.2.2 presses the reagent tube and deforms. The angle of the V-shaped deformation section becomes larger, and the free end of the V-shaped deformation section moves downward to keep the V-shaped deformation section with appropriate elastic force. When the reagent tube is withdrawn, the V-shaped deformation section restores its deformation, and the angle of the V-shaped deformation section returns to the initial state.

[0021] The test tube hole 1.1 is non-circular, and the test tube hole 1.1 is provided with an avoidance recess 1.1.1 corresponding to the deformation part 2.2 of the spring piece 2.

[0022] As a vulnerable part, the spring piece needs to be replaced frequently. By embedding the mounting part 2.1 of the spring piece 2 in the mounting groove 1.2 on the upper surface of the rack body 1, it is convenient for the disassembly and assembly of the spring piece; and it can protect the spring piece and improve the service life of the spring piece; at the same time, the screw is lower than the upper surface of the rack body, making the test tube rack more beautiful.

[0023] There are 3×5 test tube holes arrayed on the rack body, and the spring pieces correspond to the test tube holes one by one, which is convenient for the multi-channel operation of the sampling arm of the automatic blood type analyzer.

[0024] In addition to the above embodiments, the present utility model also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present utility model.
