Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an oral swab and a sampling set for gene detection. Background Art

[0002] The samples for gene detection can be oral exfoliated cells or whole blood. When collecting oral exfoliated cells with an oral swab, in order to ensure the accuracy of sampling, generally, two oral swabs and two sampling tubes containing preservation liquid are configured for one subject. One oral swab samples the inner wall of the left oral cavity, and the other oral swab samples the inner wall of the right oral cavity. After sampling, they are respectively placed in different sampling tubes for preservation and sample submission.

[0003] In the prior art, the oral swab is stored in a packaging bag. During sampling, the sampler needs to tear open the packaging bag, and then break off the swab head of the oral swab after sampling. The whole process is time-consuming and inconvenient to operate. In the case of a large number of samples, the sampling efficiency will be very low, and it is easy to confuse the sampled and unsampled inner walls of the oral cavity.

[0004] The Chinese utility model patent with the authorization announcement number CN219374724U discloses a composite swab sampling device, which includes a grasping rod. The lower end of the grasping rod branches into several connecting parts, and the lower end of the connecting part is provided with a swab rod. The lower end of the swab rod is connected with a swab head. The number of swab rods is two, and the two swab rods are arranged in parallel. Although this patent reduces the number of times the sampler needs to tear open the packaging bag and is not easy to confuse the sampled and unsampled inner walls of the oral cavity, it is still relatively inconvenient to break off the swab rod. Content of the Utility Model

[0005] The purpose of the utility model is to provide an oral swab and a sampling set for gene detection to solve the above technical problems.

[0006] The technical solution provided by the utility model is: an oral swab for gene detection, which includes a swab rod and two swab heads. The swab head is provided with a bent-back part; a swab sleeve is sleeved at the connection between the swab rod and the swab head; the swab sleeve is divided into a main sleeve sleeved outside the swab rod and a sub-sleeve sleeved on the swab head; the swab head is provided with a second breaking point, and the second breaking point is arranged perpendicular to the center line of the swab head; a pressing opening is formed near the free end of the sub-sleeve, and a spiked part corresponding to the position of the pressing opening is arranged inside the sub-sleeve. The pressing opening is located on the outer side wall of the sub-sleeve, and the spiked part is located on the inner side wall of the sub-sleeve; the positions of the pressing opening, the spiked part and the second breaking point are matched.

[0007] Preferably, a wedge surface for preventing the swab head from moving inside the sub-sleeve is provided at the free end of the swab sleeve where it is connected to the swab head, and the shape of the side surface of the swab head matches that of the wedge surface. The setting of the wedge surface helps to prevent the swab head from moving relative to the swab sleeve when pulling the swab head, causing the second breaking point to break.

[0008] Preferably, two symmetrically arranged pull rings are connected to the secondary sleeve. The arrangement of the pull rings further facilitates the sampler to pull the swab head, enabling the swab head to fit against the oral cavity side wall of the subject.

[0009] Preferably, a first folding point is provided at the connection between the swab rod and the two swab heads, and the first folding point is arranged along the center line of the swab rod. When the two swab heads are separated, the first folding point provides a margin for the separation of the two swab heads.

Detailed Description of the Preferred Embodiments

[0023] The following is a further detailed description through specific embodiments:

[0024] Embodiment 1

[0025] As Figure 1 and Figure 2 shown, this embodiment provides an oral swab for gene detection, including a swab rod 1 and a swab head 2 which are integrally connected. The number of swab heads 2 is two, and the connection part between the swab rod 1 and the swab head 2 is in a Y - like shape. The swab head 2 is provided with a bent - back part.

[0026] A swab sleeve 5 is sleeved on the connection part between the swab rod 1 and the swab head 2, and the swab sleeve 5 is in a Y - like shape. The swab sleeve 5 is divided into a main sleeve 6 sleeved on the swab rod 1 and a sub - sleeve 7 sleeved on the swab head 2.

[0027] The swab head 2 is provided with a second folding point 4, and the second folding point 4 is arranged along the center line perpendicular to the swab head 2. When the sub - sleeve 7 is sleeved on the swab head 2, the second folding point 4 is inside the sub - sleeve 7.

[0028] It has that the swab sleeve 5 is slidably connected to both the swab rod 1 and the swab head 2. In order to ensure that the swab sleeve 5 is tightly sleeved outside the swab head 2 and prevent the situation that when pulling the swab head 2, the swab head 2 moves relative to the swab sleeve 5 and causes the second folding point 4 to break, a wedge surface 10 ( Figure 2 ) for preventing the swab head 2 from moving inside the sub - sleeve 7 is provided at the free end of the connection between the swab sleeve 5 and the swab head 2, and the shape of the side surface of the swab head 2 matches that of the wedge surface 10.

[0029] An arc - shaped pressing opening 8 is opened near the free end of the sub - sleeve 7, and the pressing opening 8 is used to prompt the sampler that this position is the pressing operation position. An integrally - connected spike part 9 corresponding to the position of the pressing opening 8 is arranged inside the sub - sleeve 7. The pressing opening 8 is on the outer side wall of the sub - sleeve 7, and the spike part 9 is on the inner side wall of the sub - sleeve 7. The positions of the pressing opening 8, the spike part 9 and the second folding point 4 match.

[0030] In addition, a gap 11 for arranging the spike part 9 is left between the sub - sleeve 7 and the swab head 2. Preferably, two pairs of pressing openings 8 arranged opposite to each other, and two pairs of spike parts 9 arranged opposite to each other can be provided on the sub - sleeve 7. Or the pressing openings 8 and the spike parts 9 are both arranged in a ring around the second folding point 4.

[0031] As Figure 1As shown, in order to facilitate pulling the swab head 2 and make the swab head 2 fit better with the inner wall of the oral cavity, two symmetrically arranged pull rings 12 are integrally connected to the auxiliary sleeve 7.

[0032] A first fold point 3 is provided at the connection of the swab rod 1 and the two swab heads 2, and the first fold point 3 is arranged along the center line of the swab rod 1. In the natural state, the free ends of the two swab heads 2 are close to each other. When the pull ring 12 is pulled and the auxiliary sleeve 7 drives the two swab heads 2 to move away, the first fold point 3 can provide a margin for the two swab heads to move away.

[0033] In order to further facilitate the sampler to control the separation of the two swab heads 2, a pressing edge 13 is integrally connected to the free end of the main sleeve 6.

[0034] The oral swab provided by the present utility model is wrapped with an outer package.

[0035] During sampling, tear off the outer package, carefully take out the oral swab provided by the present utility model, insert the two swab heads 2 into the sampler's oral cavity. The sampler pinches the pressing edge 13 with the fingers of one hand and pulls a pull ring 12 with the other hand. The pull ring 12 drives the pull ring 12 and the unilateral swab head 2, so that one side of the swab rod 1 fits with the inner wall of the oral cavity of the subject, facilitating the swab head 2 to sample one side of the oral cavity. After sampling one side of the oral cavity, then pull the other pull ring 12 to make the other side of the swab rod 1 fit with the inner wall of the oral cavity of the subject for sampling. Since a first fold point 3 is provided at the connection of the swab rod 1 and the two swab heads 2, during the pulling process, the first fold point 3 will crack as the two swab heads 2 separate, thus facilitating the separation of the two swab heads 2.

[0036] After sampling, after sampling, the sampler presses the swab head 2 against the pressing opening 8 ( Figure 2 ), and the spiked portion 9 pierces into the second fold point 4 to achieve the purpose of quickly and accurately breaking off the swab head 2.

[0037] Embodiment 2

[0038] As Figure 3 and Figure 4 shown, the present embodiment provides a sampling set including the oral swab for gene detection described above, specifically including a storage tube 14, a sampling box 15, and the oral swab provided in Embodiment 1. The sampling box 15 is open upward, and a tube slot 16 for placing the storage tube 14 and a swab slot 17 for placing the packaged oral swab are provided on the sampling box 15. The storage tube 14 contains a preservation solution. The tube slot 16 is used in matching with the storage tube 14.

[0039] During sampling, the storage tube 14 is placed in the tube slot 16 to play a role in fixing and preventing it from tipping over. After sampling, after sampling, the sampler inserts the swab head 2 into the storage tube 14, presses the pressing opening 8, and the spiked portion 9 pierces into the second fold point 4 to achieve the purpose of quickly and accurately breaking off the swab head 2.

[0040] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
