Description

Reaction plate for automatic biochemical analyzer

Technical Field The utility model relates to medical equipment, in particular to a reaction plate used in a fully automatic biochemical analyzer.

Background technology The reaction plate of the prior art fully automatic biochemical analyzer is uniformly processed with fan-shaped positioning grooves in the circumferential direction of the reaction plate, and the corresponding reaction cup chain is placed in the fan-shaped positioning groove, and the front of the reaction cup chain port is used to 1. The lower plane of the rear side flange cooperates with the reaction disc to be positioned in the vertical direction, and is positioned in the radial and circumferential directions by matching the shape of the reaction cup chain with the fan-shaped positioning groove. The fan-shaped positioning groove needs to be matched with an elastic element, which is used to fasten the reaction cup chain to prevent the reaction cup chain from shaking during the test. The disadvantages of such a reaction tray are: 1. The processing of the fan-shaped positioning groove and the assembly of the elastic element are relatively complicated; 2. When manually replacing the cuvette chain, the entire cuvette chain must be taken out from the fan-shaped positioning groove and then inserted into another One reaction cup chain, the distance of taking out and inserting is longer, it is inconvenient to replace the reaction cup chain; 3. The vertical direction of the reaction cup chain is positioned by the contact between the lower plane of the flange and the reaction plate, due to the flatness of the lower plane of the flange It is difficult to ensure that the longer the cup chain is, the more prominent the problem is, so the vertical positioning of the reaction cup chain is not ideal; Inaccurate positioning may easily cause the center of the beam to deviate from the center of the optical surface of the cuvette, resulting in measurement errors.

The content of the utility model The technical problem to be solved by this utility model is to avoid the shortcomings of the above-mentioned prior art and propose a reaction plate for a fully automatic biochemical analyzer that is simple to manufacture, accurate in positioning and convenient to replace the reaction cup chain.

The utility model solves the technical problem and can realize by adopting the following technical solutions:

Designing and manufacturing a reaction disk for a fully automatic biochemical analyzer, including a disk connected to the rotating mechanism of the analyzer, on the upper surface of the disk, on the circumference near the edge of the disk, uniformly At least two pairs of dowel pins. When in use, it is enough to fit the two matching mounting and positioning post sleeves on the correspondingly designed cuvette chain onto the corresponding positioning pins.

The positioning pin is cylindrical or conical.

On the circumference of the disc near the edge, each pair is uniformly provided with round holes or round pits, and the roots of the cylindrical or conical positioning pins are embedded in the round holes or pits according to the requirements of interference fit. in the circular pit.

There are eight pairs of positioning pins, and each pair is evenly distributed on the disc as a group.

The eight pairs of positioning pins are located on the same circle with the same center as the disc.

Compared with the prior art, the technical effects of the utility model for the reaction tray of the automatic biochemical analyzer are: 1. Simple manufacture and low cost; 2. Accurate positioning of the reaction cup chain: the vertical direction of the reaction cup chain, Use the lower end surface of the installation and positioning column sleeve on the reaction cup chain to contact the reaction plate. Due to the small contact surface, accurate positioning is easy to achieve; the radial and tangential directions of the reaction cup chain use circular or conical mounting holes to contact the reaction plate. The matching positioning pins cooperate to ensure accurate positioning; 3. It is convenient to manually replace the cuvette chain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Below in conjunction with the preferred embodiments shown in the drawings, further details will be given.

A reaction disc for a fully automatic biochemical analyzer, as shown in Figure 1 and Figure 2, includes a disc 1 connected to the analyzer rotating mechanism, on the upper surface of the disc 1, close to the disc On the same circumference of the edge, eight pairs of cylindrical or conical positioning pins 11 are evenly arranged in a group, and the eight pairs of positioning pins 11 are located on the same circumference with the same center of circle as the disc 1 . The eight pairs of locating pins 11 are fixed on the disk 1 in the following manner: on the same circumference of the disk 1 near the edge, each pair is evenly opened with round holes or circular pits as a group. , the root of the cylindrical or conical positioning pin 11 is embedded in the circular hole or circular recess according to the requirement of interference fit. Shown in Fig. 3 is the cuvette chain 2 that is used in conjunction with the reaction disc of the utility model for the automatic biochemical analyzer. The inner surface of the cuvette chain 2 is provided with two mounting and positioning post sleeves 21, and the two positioning post sleeves Mounting holes 22 matching the positioning pins 11 are respectively provided in the center of the mounting holes 21 . When in use, as shown in FIG. 4 , it is enough to install the two positioning post sleeves 21 on the cuvette chain 2 on the corresponding positioning pins 11, and each pair of positioning pins 11 is correspondingly installed with a cuvette chain. 2. Figure 4 shows that two reaction cup chains 2 are installed on the reaction tray, and eight reaction cup chains can be installed on the reaction tray of the present invention.
