Description

Technical Field

[0001] The utility model relates to the technical field of medical sample tubes, and more specifically, to a sample tube for microbiological testing. Background Art

[0002] Sample tubes for microbial testing are mainly used for the collection and transportation of infectious disease specimens. They mainly consist of sampling swabs, sampling preservation fluid and plastic tubes. Generally, samples are obtained by sampling the patient's nasopharynx, placed in the preservation fluid of the plastic tube for storage and transported to the laboratory for testing.

[0003] During use, existing virus sampling tubes are usually sealed with screw caps, which have poor sealing effects. As a result, the screw caps of the sampling tubes are easily loosened due to vibration and collision during transportation after collection, causing leakage of microbial samples and posing certain safety hazards.

[0004] In view of this, research and improvement are conducted on the existing problems, and a sample tube for microbiological testing is provided, aiming to solve the problems and improve the practical value through this technology. Utility Model Content

[0008] As a further optimization of the technical solution, the upper tooth portion of the sample tube for microbiological testing of the utility model is a right-angled triangle protrusion, and the hypotenuse of the right-angled triangle protrusion faces the tightening direction of the sealing cover.

[0009] As a further optimization of the technical solution, the elastic ring of the sample tube for microbiological testing of the utility model is a circular ring structure made of elastic material, and the elastic ring is provided in multiple locations.

[0011] As a further optimization of the technical solution, the movable ring of the sample tube for microbiological testing of the utility model is a circular ring structure.

[0012] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0013] 1. The upper teeth of the utility model are right-angled triangle protrusions, and the hypotenuse of the right-angled triangle protrusions faces the tightening direction of the sealing cover. The lower end array of the sealing cover is provided with an upper teeth portion, and the lower teeth portion array is arranged on the top surface of the moving circle, and the lower teeth portion is meshed with the upper teeth portion. When the sealing cover is tightened, the lower teeth portion slides relative to the upper teeth portion, which is the same as the use of ordinary sample tubes. When the sealing cover is sealed, the lower teeth portion is meshed with the upper teeth portion, which reduces the problem of loosening of the sealing cover due to vibration and collision during transportation, resulting in sampling leakage.

When the sealing cover 2 is tightened, the upper tooth portion 3 and the lower tooth portion 7 slide relative to each other, thereby improving the convenience of use; the fixed ring 4 is fixedly arranged on the outer wall of one end of the sample tube body 1 close to the sealing cover 2; the moving ring 6 is a circular ring structure; the moving ring 6 is movably arranged above the fixed ring 4, and the moving ring 6 is connected to the fixed ring by the elastic ring 5 4 connection; the lower teeth 7 are arranged in an array on the top surface of the moving circle 6, and the lower teeth 7 are meshed with the upper teeth 3; the elastic ring 5 is a circular ring structure made of elastic material, and the elastic ring 5 is arranged in multiple places. The elastic force of the elastic ring 5 makes the moving circle 6 close to the sealing cover 2, and the rebound force generated by the elastic ring 5 when the moving circle 6 rotates makes the lower teeth 7 generate a thrust on the upper teeth 3, thereby improving the sealing firmness of the sealing cover 2; when the sealing cover 2 is sealed, the lower teeth 7 are meshed with the upper teeth 3, thereby reducing the problem of loosening of the sealing cover 2 caused by vibration and collision during transportation, thereby causing sampling leakage; the pulling column 8 is fixedly arranged at four places on the outer wall of the moving circle 6; the pulling column 8 is a circular columnar structure, and the movement and rotation of the moving circle 6 are controlled by the pulling column 8.

[0024] Specific implementation steps:

[0025] After sampling is completed, the sealing cover 2 is screwed onto the sample tube body 1. During the screwing process, the upper tooth portion 3 and the lower tooth portion 7 produce relative sliding, which is the same as the use of common sample tubes. After the sealing cover 2 is tightened, the pulling column 8 is pulled to compress the elastic ring 5, so that the moving ring 6 rotates downward and in the opposite direction of the tightening direction, and the pulling column 8 is loosened to make the upper tooth portion 3 and the lower tooth portion 7 engage. The lower tooth portion 7 is acted on by the rebound force of the elastic ring 5, which produces a thrust on the upper tooth portion 3 to prevent the sealing cover 2 from loosening; when the sealing cover 2 needs to be opened, the pulling column 8 is pulled downward, the moving circle 6 moves downward, the lower tooth portion 7 is separated from the upper tooth portion 3, and the sealing cover 2 can be opened by rotating it.

The lower end array of the sealing cover is provided with an upper tooth portion, and the lower tooth portion array is arranged on the top surface of the moving circle, and the lower tooth portion is meshed with the upper tooth portion. When the sealing cover is tightened, the lower tooth portion slides relative to the upper tooth portion, which is the same as the use of an ordinary sample tube. When the sealing cover is sealed, the lower tooth portion is meshed with the upper tooth portion, thereby reducing the problem of loosening of the sealing cover caused by vibration and collision during transportation, resulting in sampling leakage; the elastic ring is a circular ring structure made of elastic material, and the elastic ring is arranged in multiple places. The moving circle is connected to the fixed ring through the elastic ring, and the lever column is in Four settings are fixedly arranged on the outer wall of the moving ring. When the sealing cover needs to be opened, the lever column is pulled downward, the elastic ring is compressed, the moving ring moves downward, the upper tooth portion is separated from the lower tooth portion, and the sealing cover can be opened. The use is simple and convenient. After the sealing cover is tightened, the moving ring is rotated in the opposite direction, the elastic ring is deformed to generate a rebound force, and after the upper tooth portion is meshed with the lower tooth portion, the lower tooth portion generates a thrust in the opposite direction to the upper tooth portion. The sealing cover is firmly and reliably sealed and has a simple structure.
