Problems solved by technology

It is only suitable for tubes of a single height size, there is no solution for tubes of different heights
As far as the current functional requirements are concerned, it is necessary to open the test tube cap and cover the test tube cap after sampling. The above-mentioned solution is difficult to achieve this functional requirement.

Abstract

The invention provides an uncapping method of a test tube. The uncapping method is used for achieving the two work processes of test tube cap removal and test tube capping. The uncapping method is achieved through a test tube uncapping mechanism. The uncapping method of the test tube is used for solving the clamping problem of a test tube cap, and the test tube cap is clamped under the condition of reducing external force applied to the test tube cap. Meanwhile, in the test tube cap removal process, the functions that the test tube cup rotates while ascending and the test tube is capped with the test tube cap again can be achieved, and the uncapping method can be compatible with test tubes and test tube caps different in height.

Description

technical field [0001] The invention relates to a test tube cap removal method, which belongs to the field of medical instruments. Background technique [0002] At present, medical blood collection tubes are usually vacuum blood collection tubes, which realize the blood collection function through negative pressure. In the process of analyzing blood samples by clinical laboratory instruments, the following two methods are generally used: [0003] 1. Remove the test tube cap in advance, and use a disposable plastic needle for blood sample extraction; [0004] 2. Use hard needles such as steel needles to penetrate the test tube cap to realize the extraction of blood samples. [0005] In the second solution, the sampling needle needs to be used multiple times, and in order to avoid cross-contamination between samples, it is necessary to provide an additional cleaning mechanism for the sampling needle. Therefore, the first method is adopted, that is, the cap of the test tube ...
