Description

Technical Field

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

[0002] Human papillomavirus (HPV) is a spherical DNA virus that is widely present in nature. It has humans as its only host and is very resistant to drying and can be stored for a long time. The main transmission routes include contact transmission, sexual transmission, and mother-to-child transmission.

[0003] At present, a Chinese patent has disclosed a portable HPV detection stick (publication number CN216417232U). The structural design of the utility model is reasonable and ingenious. When in use, the bottom plate is supported, and the stick is inserted into the human body and the cervix is ​​scraped with the brush head to obtain a sample. After the brush head is removed, the tank body is covered and the sample is stored in the tank body for easy transportation and carrying.

[0004] Since the above-mentioned brush head needs to be manually placed back into the tank by the operator after use, the operator needs to avoid contact between the brush head and the opening of the tank during this process, otherwise the opening of the tank will easily scratch the sample taken by the brush head, which will pose a safety hazard of contact transmission. However, this also increases the difficulty of placement for the operator and has a high threshold for use.

[0005] Therefore, a portable HPV detection stick is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a portable HPV detection stick in order to solve the above problems, thereby improving the problem that the portable HPV detection stick is difficult to place and seal after detection, which is inconvenient for operators to use.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions, a portable HPV detection stick, comprising: a stick body, one end of which is fixedly connected to a brush head; a protective device, the protective device is threadedly connected to the surface of the stick body, and the brush head is arranged on the inner side of the protective device;

[0008] Preferably, the surface of the rod body is provided with a first external thread, and the protective device includes a threaded sleeve sleeved on the surface of the rod body, the first external thread is threadedly connected to the inner side of the threaded sleeve, the brush head is arranged on the inner side of the threaded sleeve, and one end of the threaded sleeve is threadedly connected to a threaded sealing cap. The operator only needs to slide the threaded sleeve along the surface of the rod body to completely cover the brush head with the threaded sleeve, and confine the brush head inside the threaded sleeve by the threaded sealing cap. During this process, the threaded sleeve and the brush head always remain parallel, so that the threaded sleeve does not contact the brush head, which effectively reduces the probability of the brush head sample being scratched and retained outside the threaded sleeve, thereby reducing the probability of contact transmission.

[0009] Preferably, a sealing gasket is provided inside the threaded sealing cap, and one end of the sealing gasket contacts the threaded sleeve, which can improve the sealing performance between the threaded sealing cap and the threaded sleeve, thereby reducing the probability of sample leakage.

[0010] Preferably, a limiting ring sleeve disposed inside the threaded sleeve is fixedly connected to the surface of the rod body. One end of the limiting ring sleeve contacts the inner wall of the threaded sleeve, and the diameter of the limiting ring sleeve is larger than the diameter of the first external thread. This can prevent the threaded sleeve from directly contacting the brush head, further avoiding the probability of the threaded sleeve scratching the brush head. At the same time, it can also function to prompt the operator that the threaded sleeve has been adjusted in place, preventing the operator from over-rotating.

[0011] Preferably, a sealing ring that contacts the threaded sleeve is sleeved on the surface of the limiting ring sleeve, and the inner diameter of the sealing ring is larger than the diameter of the first external thread. This can block the gap between the limiting ring sleeve and the threaded sleeve, further reducing the probability of sample leakage.

[0012] Preferably, a second external thread matching the first external thread is provided on the surface of the rod body, and the second external thread is disposed outside the threaded sleeve. The operator can thread-connect the threaded sleeve separated from the first external thread to the second external thread, which can prevent the threaded sleeve from sliding along the rod body during the sampling process of the operator, thereby reducing the interference with the operator's sampling.

[0013] Preferably, two bending grooves are provided on the surface of the rod body, and the two bending grooves are symmetrically distributed on both sides of the axis of the rod body. The bending grooves are disposed outside the threaded sleeve. The operator can easily break the rod body through the bending grooves according to needs. At this time, the overall volume of the HPV detection rod is reduced, making it more convenient to carry, thereby improving the portability of the HPV detection rod. At the same time, it can also reduce the probability of the sample remaining on the surface of the rod body, further reducing the safety hazard of HPV virus transmission through contact.

[0014] Preferably, the protection device further includes a protection cylinder, which is fixedly connected to the other end of the threaded sleeve, and the bending groove is disposed inside the protection cylinder. This can cover the fracture of the rod body after breaking, so as to reduce the fracture from contacting or scratching surrounding objects, and further improve the safety factor when carrying the broken HPV detection rod.

[0015] Preferably, an adjusting piece is fixedly connected to the other end of the rod body, and uniformly distributed anti-slip grooves are provided at both ends of the adjusting piece. This can enable the operator to hold the rod body more stably, making the sampling and adjusting operations more stable.

[0016] The beneficial effects of the present utility model are:

[0017] 1. The operator only needs to completely cover the brush head by sliding the threaded sleeve along the surface of the rod body, and limit the brush head inside the threaded sleeve through the threaded sealing cover. During this process, the threaded sleeve and the brush head always remain parallel, so that the threaded sleeve will not contact the brush head, which effectively reduces the probability that the brush head sample is scratched and remains outside the threaded sleeve, and further reduces the probability of contact transmission.

[0018] 2. The operator can easily break the rod body through the bending groove according to needs. At this time, the overall volume of the HPV detection rod is reduced, making it more convenient to carry, so as to improve the portability of the HPV detection rod. At the same time, this can also reduce the probability that the sample remains on the surface of the rod body, and further reduce the safety hazard of the HPV virus being transmitted through contact.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] During specific implementation: As Figures 1 - 5As shown in the figure, a portable HPV detection stick includes: a stick body 1, with a brush head 2 fixedly connected to one end of the stick body 1; a protection device 3, which is threadedly connected to the surface of the stick body 1, and the brush head 2 is arranged inside the protection device 3; a regulating piece 6 is fixedly connected to the other end of the stick body 1, and evenly distributed resistance-increasing grooves 61 are formed at both ends of the regulating piece 6.

[0027] As Figure 3 , Figure 4 and Figure 5 As shown in the figure, a first external thread 11 is formed on the surface of the stick body 1. The protection device 3 includes a threaded sleeve 31 sleeved on the surface of the stick body 1. The first external thread 11 is threadedly connected to the inside of the threaded sleeve 31. The brush head 2 is arranged inside the threaded sleeve 31. One end of the threaded sleeve 31 is threadedly connected with a threaded sealing cover 32; a sealing gasket 33 is arranged inside the threaded sealing cover 32, and one end of the sealing gasket 33 contacts the threaded sleeve 31; a limiting ring sleeve 4 arranged inside the threaded sleeve 31 is fixedly connected to the surface of the stick body 1. One end of the limiting ring sleeve 4 contacts the inner wall of the threaded sleeve 31. The diameter of the limiting ring sleeve 4 is larger than that of the first external thread 11; a sealing ring 5 contacting the threaded sleeve 31 is sleeved on the surface of the limiting ring sleeve 4, and the inner diameter of the sealing ring 5 is larger than that of the first external thread 11; a second external thread 12 matching the first external thread 11 is formed on the surface of the stick body 1, and the second external thread 12 is arranged outside the threaded sleeve 31.

[0028] As Figure 3 , Figure 4 and Figure 5 As shown in the figure, two bending grooves 13 are formed on the surface of the stick body 1. The two bending grooves 13 are symmetrically distributed on both sides of the axis of the stick body 1. The bending grooves 13 are arranged outside the threaded sleeve 31. When the operator needs to carry the brush head 2 after collection for inspection when going out, the operator can break the stick body 1 by repeatedly bending the stick body 1 near the bending grooves 13. At this time, the overall volume of the HPV detection stick is reduced, making it more convenient to carry. At the same time, this can also reduce the probability of the sample remaining on the surface of the stick body 1, further reducing the safety hazard of HPV virus transmission through contact; the protection device 3 further includes a protection cylinder 34, and the protection cylinder 34 is fixedly connected to the other end of the threaded sleeve 31. The bending grooves 13 are arranged inside the protection cylinder 34.

[0029] When the utility model is in use, first unscrew the threaded sealing cap 32 so that the larger opening of the threaded sleeve 31 is exposed. Then slide the threaded sleeve 31 along the first external thread 11 in the direction away from the limit ring sleeve 4. At this time, the threaded sleeve 31 and the brush head 2 move relative to each other, and the brush head 2 gradually moves towards the outside of the threaded sleeve 31. After the threaded sleeve 31 is separated from the first external thread 11, the position of the threaded sleeve 31 can be adjusted by sliding. At this time, the brush head 2 is completely exposed. Then, the brush head 2 can be placed at the vagina or cervix of the subject to extract samples through the rod body 1;

[0030] After the sample extraction is completed, push the threaded sleeve 31 towards the brush head 2. At this time, the threaded sleeve 31 slides along the rod body 1 and gradually covers the brush head 2 until the brush head 2 is completely hidden inside the threaded sleeve 31. During this process, the threaded sleeve 31 and the brush head 2 always remain parallel, so that the threaded sleeve 31 does not contact the brush head 2. This effectively reduces the probability that the sample of the brush head 2 is scratched and stays outside the threaded sleeve 31, thereby reducing the probability of contact transmission. After the threaded sleeve 31 is docked with the first external thread 11, screw the threaded sleeve 31 onto the surface of the first external thread 11 until the threaded sleeve 31 abuts against the limit ring sleeve 4. Finally, screw the threaded sealing cap 32 back onto the end of the threaded sleeve 31 and tighten it. Then it can be sent for inspection.

[0031] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
