Abstract

The invention relates to a device for container sealing and leak-proofing, in particular to a stopper for blocking the opening of a test tube and a test tube assembly using the stopper. The stopper provided by the invention comprises a sealing part and a hanging part; the hanging part is integrated with the sealing part, the hanging part is provided with a horizontal opening, and the horizontal opening is used for cooperating with the outer side wall of the test tube. The test tube assembly provided by the invention has the advantages of good airtightness, not easy leakage during transportation and collection process, and quick and convenient disassembly and assembly.

Description

technical field [0001] The invention relates to a device for sealing and leak-proofing a container, in particular to a stopper for blocking the opening of a test tube and a test tube assembly using the stopper. Background technique [0002] The body fluid of the tester needs to be sent for inspection, and a storage device is required and can be sent to the testing equipment for testing. Most of the existing technologies use test tubes as devices for storing body fluids and testing them on testing equipment. However, during the process of collecting body fluid and transportation, the liquid in the test tube will flow out, causing pollution. [0003] The test tube stopper of prior art has the following methods: [0004] It is integrated with the test tube, but this kind of processing is difficult and expensive. [0005] It is separated from the test tube. When there is no liquid or other substances in the test tube, first fit the stopper with the opening of the test tube. ...
