Description

Technical Field

[0002] In the laboratory of a hospital, it is necessary to test various patient samples. There are many types of test items and various forms. Among them, in the process of testing various liquids such as blood and urine, it is often necessary to take out part of the liquid from the storage container (usually a test tube) and transfer it to the container for testing (such as a test tube). Before the transfer, the container for testing is pre-stored with reagents for testing. Different test items use different reagents, and the amount of reagents and the amount of sampling may also be different. Therefore, after collecting a batch of liquid samples, they will be classified according to the information stickers pasted on the liquid sample tubes (pasted when sampling, containing the patient's name, gender, test time, test items and other information), and then determine the reagents for testing one by one, put the reagents into the reagent tubes one by one, and then use the sampler to sample the liquid samples in turn, and then inject them into the corresponding reagent tubes. This process mainly relies on manual operation, so it is time-consuming and labor-intensive, and the inspection efficiency is low. Summary of the invention

In this embodiment, the scanning gun 7.1 is used for scanning, and it can move within the range of the test tube rack 2 to collect information from all sample test tubes 2.1 on the test tube rack 2. Therefore, the information sampling component 7 of the present invention also includes a scanning transverse moving structure and a scanning horizontal telescopic structure 7.2; the scanning transverse moving structure is used to drive the scanning horizontal telescopic structure 7.2 and the scanning gun 7.1 installed thereon to move along the width direction of the test tube rack 2; the fixed section of the scanning horizontal telescopic structure 7.2 is installed on the scanning transverse moving structure, and the scanning gun 7 is installed at its telescopic end. .1, the scanning horizontal telescopic structure 7.2 is used to drive the scanning gun 7.1 to move above the test tube rack 2 along the length direction of the test tube rack 2, and the scanning gun 7.1 is located on the outside of the test tube rack 2 when the scanning horizontal telescopic structure 7.2 is at the maximum contraction, that is, the scanning gun 7.1 and the test tube rack 2 do not interfere with each other, and the test tube rack 2 can be freely disassembled and assembled from the sample placement seat 1.1.

[0073] In the present invention, the sample adding component 8 realizes the addition of reagents to realize the chemical analysis of samples. In this embodiment, the sample adding component 8 includes a sample adding lateral moving structure, a sample adding horizontal telescopic structure 8.2 and a plurality of sample adding tubes 8.1; the sample adding lateral moving structure is used to drive the sample adding horizontal telescopic structure 8.2 and the plurality of sample adding tubes 8.1 installed thereon to move along the width direction of the reagent rack 3; the fixed section of the sample adding horizontal telescopic structure 8.2 is installed on the sample adding lateral moving structure, and a plurality of sample adding tubes 8.1 are installed at its telescopic end, and the plurality of sample adding tubes 8.1 are located above the reagent rack 3, and they move along the length direction of the reagent rack 3 under the action of the sample adding horizontal telescopic structure 8.2, and each sample adding tube 8.1 moves along the length direction of the reagent rack 3. .1 is located outside the reagent rack 3 when the sample loading horizontal telescopic structure 8.2 is in the maximum contraction state, that is, it is not located directly above the reagent rack 3, so that the reagent rack 3 can be detachably placed on the reagent tube placement seat 1.2; one end of each sample loading tube 8.1 is a sample loading port, and the sample loading ports of multiple sample loading tubes 8.1 are staggered, and the sample loading port of each sample loading tube 8.1 is moved directly above the sample test tube 2.1 of the reagent rack 3 through the sample loading lateral moving structure and the sample loading horizontal telescopic structure 8.2; the other end of each sample loading tube 8.1 is connected to a sample loading pump through a sample loading connecting tube, and each sample loading pump is connected to a reagent bottle 8.3. That is, through the cooperation of the sample loading lateral moving structure and the sample loading horizontal telescopic structure 8.2, the sample loading tube 8.1 can be moved directly above each reagent test tube 3.1, thereby achieving accurate addition of reagents. For the arrangement of the above-mentioned multiple sample tubes 8.1, the sample ports of the multiple sample tubes 8.1 can be arranged at intervals along the length direction of the reagent rack 3 to achieve the correspondence of the sample ports to the reagent test tube 3.1, which is not shown in the drawings of the present invention.

In the present invention, the sample loading lateral moving structure is similar to the above-mentioned moving structure, and its form is also various. The attached figure of this embodiment shows a motor-screw assembly; the same is true for the sample loading horizontal telescopic structure 8.2, which shows a telescopic rod structure; the sample loading rotating part 8.4 is a rotating motor structure.In addition, it should be noted that, considering that the sample addition port is located directly above the reagent test tube 3.1 when the reagent is added, the added reagent may splash and contaminate other reagent test tubes 3.1.
