Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a splash-proof virus sampling tube. Background Art

[0002] With the decline of virus and antibiotic resistance in recent years, the variability of pathogens has increased, and high-throughput nucleic acid testing is receiving more and more attention. Sample collection is an important part of nucleic acid testing. Secretions are collected from the patient's pharynx or tonsils through pharyngeal swabs. After sampling, the sampling stick is broken and the pharyngeal swab containing the specimen is placed in the sampling tube. However, in actual use, in the process of breaking the sampling stick, the sampling stick is often difficult to break and the virus preservation solution splashes, leading to infectious occupational exposure. At the same time, during transportation, the sampling tube will experience bumps and other phenomena, and the consequences of leakage of the virus preservation solution are more serious. Therefore, the current sampling tube has insufficient sealing performance and needs to be improved to further improve the sealing performance. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a sampling tube which has good sealing performance and can effectively prevent viruses from splashing.

A splash-proof plate is arranged at the tube mouth of the sampling tube body, an operating port is opened on the splash-proof plate, and a sampling rod buckle is arranged at the edge of the operating port; the operating port is formed as an arc or a straight line, the sampling rod buckle is formed as a concave arc or straight line edge, and the junction between the sampling rod buckle and the arc or straight line edge is a buckle shrinkage tightening portion; the operating port is in the shape of a sector, the sampling rod buckle is arranged at the center of the sector, a sealing gasket is arranged in the sampling tube cover, the top of the sealing gasket is a gasket, and a spike structure is arranged on the gasket.

[0005] Preferably, the angle of the sector is 15-45°.

[0006] Preferably, the radius of the sector is 1-1.5 times the radius of the pipe mouth.

[0007] Preferably, a sealing gasket is provided in the sampling tube cover, the top of the sealing gasket is a gasket, and a spike structure is provided on the gasket.

[0008] Preferably, the spike structure on the sealing gasket is arranged around the inner side of the sampling tube cover.

[0009] Preferably, the peak structure of the sealing gasket is a flexible body.

[0010] The utility model is provided with a splash plate, an operation port, and a sampling rod buckle, which can effectively prevent splashing during operation; the utility model preferably adopts a fan-shaped operation port, and the sampling rod buckle is arranged at the center of the fan-shaped circle, so that the sampling rod can be more conveniently slid into the sampling rod buckle during operation. The utility model adopts a sealing gasket with a spike structure as a sealing layer, which can obtain a better sealing effect than a traditional sealing layer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4 As shown, the splash-proof virus sampling tube of the utility model includes a sampling tube cover 1 and a sampling tube body 2. A sealing thread 21 is provided on the upper outer surface of the sampling tube body 2, and a corresponding thread is provided on the side wall of the sampling tube cover 1. The sampling tube body and the sampling tube cover are tightened and sealed by the sealing thread. A sealing gasket 11 is provided in the sampling tube cover 1, and the top of the sealing gasket is a gasket 12 that matches and fits the sampling tube cover 1, and a spike structure 13 is provided on the gasket. In a further embodiment, the spike structure 13 on the sealing gasket 11 is arranged around the inner side of the sampling tube cover 1. When the sampling tube cover 1 is tightened on the sampling tube body 2, the peak part of the spike structure of the sealing gasket 11 will be at the inner edge of the tube mouth. The tighter the sampling tube cover 1 is screwed, the better the sealing effect. The spike structure of the sealing gasket 11 is a flexible body. When the sampling tube cover 1 and the sampling tube body 2 are screwed together, the flexible body will have a certain extrusion deformation to effectively improve the sealing of the sampling tube. The material of the spike structure is silicone, PET, etc.

[0018] The tube mouth of the sampling tube body 2 is provided with a splash plate 3, which is fixed on the sampling tube body 2. The splash plate 3 is provided with an operation port 32, and a sampling rod buckle 31 is provided at the edge of the operation port 32. Preferably, the operation port 32 is formed as an arc or a straight line, and the sampling rod buckle 31 is formed by the arc or the straight line edge being concave in the direction of the splash plate, and the connection between the sampling rod buckle 31 and the arc or the straight line edge is a buckle shrinking tightening part 33. As a preferred technical solution, the shape of the operation port 32 is a fan or an arc, and the sampling rod buckle 31 is arranged at the center of the fan. If the operation port 32 is set too large, it will cause splashing during operation, but if the operation port 32 is set too small, the sample carrier, such as a cotton swab, will be inconvenient to operate when it is put into the sampling tube body and it is easy to contaminate the outside or the opening of the sampling tube body. Therefore, the angle of the fan is 15-45°, and the radius of the fan is 1-1.5 times the tube mouth radius, which is a better value range. For the convenience of manufacturing, the sector shape mentioned in the utility model is not a strict mathematical sector shape, but a figure formed by taking a section of an arc on the circular edge of the pipe mouth, taking a point on the center line of the arc, and connecting this point with the two ends of the arc, and this point is the center of the sector shape mentioned in the utility model. Here, the angle of the sector shape refers to the degree of this section of the arc, and the radius of the sector shape refers to the distance between the center of the sector shape and the midpoint of this section of the arc.

[0019] During use, the sampling tube body 2 is filled with virus preservation liquid 4. After the sampling rod is sampled, it is inserted from the operation port 32 and then stuck on the sampling rod buckle 31. The sampling stick is then broken and the sampling tube cover 1 is screwed onto the sampling tube body 2 through threads. During the tightening process, the peak part of the spike structure of the sealing gasket 11 will be at the inner edge of the tube mouth. The tighter the sampling tube cover 1 is screwed, the better the sealing effect will be.

[0020] The above contents are merely examples and explanations of the present invention. Those skilled in the art may replace the specific embodiments described in a similar manner. As long as they do not deviate from the structure of the present invention or exceed the scope defined in the claims, they shall fall within the protection scope of the present invention.
