Description

Technical Field

[0001] The invention relates to the field of medical technology, in particular to a throat swab and sampling tube set. Background Art

[0002] The substance of nucleic acid testing is the nucleic acid of the virus. Nucleic acid testing is to find out whether the nucleic acid of the foreign invading virus is present in the patient's respiratory specimens, blood or feces to determine whether the patient is infected with the new coronavirus. Therefore, once the nucleic acid test is "positive", it can be proved that the virus exists in the patient's body.

[0003] After the new coronavirus infects the human body, it will first multiply in the respiratory system, so it is possible to determine whether the human body is infected with the virus by testing the viral nucleic acid in sputum and nasopharyngeal swabs. Therefore, a positive nucleic acid test can be used as a new standard for confirming new coronavirus infection.

[0004] All organisms contain nucleic acids, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The new coronavirus is a virus that only contains RNA. The specific RNA sequence in the virus is a marker that distinguishes the virus from other pathogens. After the emergence of the new coronavirus, Chinese scientists completed the analysis of the new coronavirus's full genome sequence in a very short time, and discovered the specific nucleic acid sequence in the new coronavirus by comparing it with the genome sequences of other species. During clinical laboratory testing, if the specific nucleic acid sequence of the new coronavirus can be detected in the patient's sample, it should indicate that the patient may be infected with the new coronavirus.

[0005] At present, when sampling nucleic acid, a throat swab and a sampling tube are needed. After sampling with the throat swab, the head of the throat swab is broken off and placed in the sampling tube for storage. However, during the nucleic acid sampling operation, medical staff wear protective clothing and gloves, which makes the operation inconvenient. In many cases, it is inconvenient to break the throat swab, and when using the lid to assist in breaking it, the throat swab is easy to stick to the side wall of the sampling tube. In addition, the current sampling tube is frequently opened and closed during the sampling process, which affects the final sealing. It is impossible to ensure good sealing only by threaded connection. Therefore, a throat swab and sampling tube set is designed. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art solutions, the present invention provides a throat swab and sampling tube set, which can effectively solve the problems raised by the background technology.

During the process of disengaging from the main body, when the groove comes into contact with the disassembly blade, the disassembly blade will break the connecting thin layer that supports the shaping, and then pull the throat swab main body, and the disassembly blade will cut off the connecting ribs. When the connecting ribs and the connecting thin layer are completely cut off, the spring pushes the disassembly blade to move toward the initial position, and at the same time pushes the cut throat swab main body head to fall toward the bottom end of the sampling tube main body. The sealing cover includes an outer cover, an inner wall of the outer cover is provided with an internal thread, and the outer cover is connected to the inner cover through the internal thread. A sealing gasket is provided at the lower end of the inner cover, and a plurality of sealing partitions are provided on the side wall of the sealing gasket. The inner thread provided on the outer cover is used to connect the sampling tube main body. After tightening, the inner cover provided inside is twisted again, and the inner cover pushes the sealing gasket connected thereto downward, and the side wall of the sealing gasket is squeezed against the inner wall of the sampling tube main body, wherein the sealing partitions enter the interior of the sampling tube main body layer by layer, forming a multi-level sealing structure.

[0009] Furthermore, a positioning recessed area is provided on the flat handheld end.

[0010] Furthermore, a silicone base is provided at the lower end of the sampling tube body.

[0026] The working principle of the present invention is as follows: during the design, a pharyngeal swab main body 1 and a sampling tube main body 2 are designed, wherein the pharyngeal swab main body 1 and the sampling tube main body 2 are packaged separately, but the combination of the two can be more convenient. Specifically, the upper end of the pharyngeal swab main body 1 is designed as a flat hand-held end 3, which can make it more stable for medical staff to hold the pharyngeal swab main body 1, and avoid rolling and falling due to the round cotton swab stick structure. The lower end is a pharyngeal swab cotton head 5 structure for sampling, which can complete nucleic acid sampling. After sampling, the sealing cover 9 at the upper end of the sampling tube main body 2 is opened, and the pharyngeal swab main body 1 is inserted into the sampling tube main body 2. The position of the disengagement groove 6 is aligned with the disassembly notch 12 on the disassembly mechanism 10, and is connected with the exposed disassembly blade 14. In the process of pulling up the throat swab body 1, when the disengagement groove 6 contacts the disassembly blade 14, the disassembly blade 14 breaks the connecting thin layer 8 that supports and shapes, and then the throat swab body 1 is pulled, and the disassembly blade 14 cuts off the connecting rib 7. When the connecting rib 7 and the connecting thin layer 8 are completely cut off, the spring 15 pushes the disassembly blade 14 to move toward the initial position, and at the same time pushes the cut head of the throat swab body 1 to fall toward the bottom of the sampling tube body 2, completing the entire throat swab storage operation.

[0027] As a preferred embodiment, a positioning recessed area 16 is provided on the flat hand-held end 3, which makes the hand-held portion more comfortable and stable and avoids falling off.

[0028] As a preferred embodiment, a silicone base 17 is provided at the lower end of the sampling tube body 2, which can be placed vertically to avoid tipping over. This structure is selectively used and can be used when vertical placement is required.

[0029] As a preferred embodiment, the knife holder 11 and the sampling tube body 2 are integrally formed.

[0030] As a preferred embodiment, the disassembly blade 14 is arranged obliquely on the inner wall of the sampling tube body 2 , and the inclined structure facilitates the cutting process of the throat swab body 1 .

[0031] As a preferred embodiment, the sealing cover 9 includes an outer cover 18, an internal thread 19 is provided on the inner wall of the outer cover 18, the outer cover 18 is connected to the inner cover 20 through the internal thread 19, a sealing rubber pad 21 is provided at the lower end of the inner cover 20, and a plurality of sealing partitions 22 are provided on the side wall of the sealing rubber pad 21. The sealing cover 9 is structurally innovated, and the internal thread 19 provided on the outer cover 18 is connected to the sampling tube body 2. After tightening, the inner cover 20 provided inside is twisted again, and the inner cover 20 pushes the sealing rubber pad 21 connected thereto downward, and the side wall of the sealing rubber pad 21 is squeezed with the inner wall of the sampling tube body 2, wherein the sealing partition 22 enters the sampling tube body 2 layer by layer, forming a multi-level sealing structure to ensure sealing. When disassembling, only the outer cover 18 needs to be unscrewed to drive the internal sealing rubber pad 21 to detach, and then the pharyngeal swab collected inside can be taken out.

[0032] As a preferred embodiment, a pre-cut dotted line segment 23 is provided in the middle of the connecting rib 7 , and the connecting rib 7 is pre-cut to facilitate cutting of the structure of the connecting rib 7 .

[0033] As a preferred embodiment, an umbrella-shaped splash-proof protrusion 24 is provided on the inner wall of the sampling tube body 2 to prevent splashing when falling, thereby improving hygiene.

[0034] In summary, the main features of the present invention are:

[0035] The present invention uses a throat swab and sampling tube set in combination, which can quickly separate the end of the throat swab during nucleic acid sampling, thereby improving the work efficiency of medical staff and making the nucleic acid sampling process simple and convenient to operate.
