Description

Technical Field

[0001] The utility model relates to the technical field of medical detection equipment, in particular to a sampling tube. Background Art

[0002] The sampling tube is a tool for collecting and storing samples, and has a wide range of application prospects in medical testing. The existing sampling tube is filled with a preservation solution. During the test, the tester first takes a sample with a cotton swab, then soaks the cotton swab in the sampling tube, and dissolves the test substance with the preservation solution, and then performs the test operation with the test card. The existing sampling tube adopts a method of separate packaging of the cotton swab and the collection tube. During the specific operation, the collection operation will be affected due to the loss of the cotton swab and other reasons, and there is also the problem of inconvenience in squeezing out the collection solution, which in turn causes inconvenience to the collection. Utility Model Content

[0003] The utility model provides a sampling tube to solve the deficiencies of the above-mentioned prior art. Through the integrated design of the cotton swab and the collection tube, it is convenient to collect the specimen, and it is also convenient to dissolve and squeeze out the specimen for detection, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A sampling tube comprises an extrusion hose, one end of which is closed, and the other end of which is connected to a connecting tube, an inner ring is provided at the end of the connecting tube, a connecting ring is provided at the end of the connecting tube, a dropper is provided on the connecting ring, a plurality of air holes are provided between the dropper and the connecting ring to facilitate the extrusion of the solution, an end cap is provided at the end of the dropper, a plug is threadedly connected to the connecting tube, a connecting rod is provided on the plug, a defatted collection cotton ball is provided at the other end of the connecting rod, an inner disk is provided on the connecting rod, an outer ring is provided on the inner disk, the outer ring is threadedly connected to the inner ring, and a plurality of holes are opened on the inner disk. Before sampling, the dissolved solution is stored in an extrusion hose. During the collection process, the dropper is first removed from the extrusion hose, and then sampling is performed through a defatted collection cotton ball. Before collection, the defatted collection cotton ball is located in the dropper to prevent the defatted collection cotton ball from being contaminated. After the collection is completed, the outer ring is connected to the inner ring through a thread, and the dropper is connected to the extrusion hose. The extrusion hose is then squeezed to allow the solution inside to enter the dropper, and the defatted collection cotton ball is immersed in the solution. After waiting for a period of time to dissolve, the end cap can be removed, and then the solution is squeezed out of the extrusion hose onto the test card for testing.

[0006] Furthermore, in order to facilitate the extrusion of the solution, a conical tube is formed at the other end of the dropper, an end tube is provided at the outer end of the conical tube, and an end cap is connected to the end tube through threads.

[0007] Furthermore, in order to improve the sealing effect of the end cap, an inner column is provided in the end cap, and the inner column is provided in the end tube.

[0008] The advantages of the above technical solution are:

[0009] The utility model facilitates the collection operation of the collector by integrating the cotton swab and the collection tube, and facilitates the dissolution and extrusion detection operations of the specimen. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
