Description

Technical Field

[0001] The present invention relates to the technical field of biochemical detection, and in particular to a test tube rack, a transmission sampling system and a transmission sampling method thereof. Background Art

[0002] Test tubes are commonly used instruments in biological and chemical laboratories. They are used as reaction containers for small amounts of reagents. They are used at room temperature or when heated. They are easy to use and have been widely used in hospitals, testing institutions, etc., and are widely welcomed by medical personnel. The existing test tube rack for placing test tubes is usually composed of a vertical plate, a bottom plate and a hole plate. The test tube is inserted into the jack on the hole plate to fix the test tube for easy access. In this way, the existing test tube rack has a single function, which is not conducive to the operator's need to use the test tube rack in a variety of ways. The test tube can only be moved back and forth in a time-consuming and laborious manner, which is very inconvenient, and is mainly arranged in a single row. The stability of the test tube rack during front-end sampling is poor, and when performing biochemical testing, the track needs to drive the test tube rack to change direction and then perform sampling, but the track docking technology and track installation are relatively complicated, and the track change mechanism and track integrated design require relatively high docking accuracy during installation. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a test tube rack, a transmission sampling system and a transmission sampling method thereof.

[0004] The technical solution of the present invention is as follows: on the one hand, the present invention discloses a test tube rack, comprising a test tube rack body, the test tube rack body being provided with a plurality of socket units for placing test tubes, the socket units comprising outer layer sockets arranged on opposite sides and two rows of inner layer sockets arranged on the inner sides of the outer layer sockets, the outer layer sockets and the inner layer sockets being arranged at intervals along the length direction, the outer layer sockets and the inner layer sockets being arranged alternately, a first detection groove being provided on the outer circumferential surface of the outer layer sockets, a second detection groove being provided on the outer circumferential surface of the inner layer sockets, a gap being provided between adjacent outer layer sockets, the gap being connected to the second detection groove, and an elastic clamping structure being provided on the socket unit.

[0005] It can be seen from the above scheme that the test tube rack body is used for centralized storage of test tubes, the socket unit is used for inserting test tubes through the outer socket and the inner socket, the first detection slot and the second detection slot are used for external equipment to scan the barcode on the test tube to facilitate sample tracing, and the elastic clamping structure is used to limit the inserted test tube with sample solution. Compared with the single-row test tube rack, the test tube rack body disclosed in the present invention does not rely on auxiliary devices and can be placed separately without the risk of lodging, and can realize one-stop service from front-end sampling to back-end detection. There is no need to transfer the test tube rack midway, which saves working procedures and improves the overall detection process. Through the first detection slot and the second detection slot, it supports barcode scanning of all sample tubes, can detect multiple test tubes through a single transport, and improves the response speed of detection.

It can be seen that the beam detection optical coupler is used to detect incoming materials on the test tube rack body, and the identification scanning module sequentially identifies and scans along the feeding direction through the identification scanner and the first detection opening and the second detection opening on both sides of the test tube rack body, and cooperates with the fast sampling action of the sampling mechanism to speed up the sampling rate of the sample and improve the overall detection efficiency.
