Sample frame

Abstract

The invention provides a sample frame, which can adapt to test tubes and centrifuge tubes with different specifications, and aims at providing the sample frame which is simple in structure, high in practicability and suitable for full-automatic inspection equipment. The sample frame comprises two parts, namely a main carrier body and a baffle plate; the baffle plate is arranged on the side surface of the main carrier body; a plurality of round holes for arranging the test tubes are formed in the main carrier body; a spring sheet is arranged at the lower end of the baffle plate; and a seal cover fixing structure is arranged at the upper end of the baffle plate. The sample frame is simple in structure, relatively low in cost and high in practicability; the problem that an existing sample frame cannot hold the test tubes or centrifuge tubes with various specifications is solved; and the automatic degree of an instrument is improved.

Description

technical field [0001] The invention relates to the technical field of medical testing equipment, in particular to a sample rack capable of adapting to test tubes and centrifuge tubes of different specifications. Background technique [0002] With the advancement of science and technology, the degree of automation in the laboratory is getting higher and higher, and the requirements for automated instruments are also getting higher and higher. Fully automatic inspection equipment can not only liberate the labor force, improve work efficiency, but also avoid the possibility of personnel and samples. Direct contact with items that are harmful to health, thereby ensuring the safety of experimenters. Therefore, more and more automatic inspection instruments are used in the medical field. [0003] Fully automatic testing instruments need to pre-place the sample on a sample rack at a specific position, and most of the existing sample racks are only suitable for test tubes of the s...

AI Technical Summary

Problems solved by technology

[0003] Fully automatic testing instruments need to pre-place the sample on a sample rack at a specific position, and most of the existing sample racks are only suitable for test tubes of the same specific specification, but there are many specifications for test tubes used in laboratories, and the sizes are different First, the existing single-size sample rack cannot place these test tubes. When the diameter of the test tube is smaller than the diameter of the sample rack hole, the test tube will be tilted when placed, so that the position of the sample will be skewed, and the sample needle cannot find an accurate position to draw the sample

Therefore, before the sample is tested, the experimenter must first transfer the sample to a test tube of a specific specification, which not only increases the workload of the experimenter, but also inevitably increases the probability of direct or indirect contact between the experimenter and the sample. Thereby increasing the risk of experimental personnel being infected

[0004] In addition, some foreign samples or samples that need to be stored and transported are generally stored in centrifuge tubes with sealed caps. When testing samples, the sealed caps of the centrifuge tubes need to be opened, while traditional sample racks do not have a structure to fix the sealed caps. After the cover is opened, it will cover the nozzle of itself or the surrounding centrifuge tubes, and it is easy to cross-contaminate between centrifuge tubes, and it will affect the sampling of the sampling needle

To avoid this situation, the interval between the centrifuge tubes must be increased, which takes up a lot of space, while the fully automatic inspection equipment has limited space and cannot provide enough space for the sealing cap
