Description

Technical Field

[0001] This utility model relates to the field of medical cell sampling and preservation technology, specifically to a cervical exfoliated cell preserver. Background Technology

[0002] Cervical cancer, caused by the human papillomavirus (HPV), is currently the only cancer with a clearly defined cause and poses a serious threat to women's lives. Large-scale population screening, as the primary preventative measure, faces significant challenges due to high costs and insufficient medical resources, severely limiting its coverage, especially in impoverished areas with limited medical resources. We explored new cervical cancer screening technologies and established a "self-collected cervical vaginal cell sample testing for high-risk HPV as initial cervical cancer screening" protocol, successfully implementing it in 10,000 cases. This novel screening model is not only suitable for cervical cancer screening in remote, impoverished areas with limited medical resources, but also, due to its convenience, affordability, high quality, efficiency, and the ability to participate through information networks, is equally suitable for urban populations with abundant medical resources and affluent economies. This new screening model is simple, efficient, and inexpensive, and can effectively solve the "bottleneck" problems faced by large-scale cervical cancer screening, such as high cost, low sensitivity, low participation rate, and high loss to follow-up rate. Its implementation will reduce the cost of disease prevention, maximize coverage of susceptible populations, and promote the implementation of cervical cancer prevention, a major national public health project.

[0003] Currently, in clinical practice, when examining patients for cervical cancer, it is often necessary to collect secretions from the external os of the cervix for further diagnosis. Existing technology mainly involves using a retractor to open the vagina and fully expose the external os of the cervix, then using a cervical brush to collect the secretions, and then inserting the cervical brush into a cell preservation solution to allow the sample to fall into the preservation solution for subsequent testing.

[0004] Chinese patent CN216455111U discloses a disposable cervical exfoliated cell collector. The positioning part is supported by a material capable of elastic deformation. After sampling, the broken part is broken off, separating the handle from the brush head. One end of the brush head is installed in the positioning hole. The squeezing member is rotated, squeezing the positioning part and deforming it, thereby causing the inner wall of the positioning hole to squeeze the brush head. Then, the bottle cap is closed with the collector, and the brush head is housed in the collector, fixing the broken brush head inside. The brush head is immersed in the preservation solution. During testing, the broken brush head can be removed from the preservation solution by twisting the bottle cap, which facilitates the removal of the brush head, prevents the brush head from interfering with the detection of the preservation solution, and facilitates the dissolution of the sample from the brush head in the preservation solution.

[0005] The aforementioned cervical cell collection and preservation instruments are difficult to detach from the cell brush head during use, increasing the workload and intensity for medical staff. Furthermore, the cervical brush being immersed in the cell preservation solution prevents the cap from closing properly, and the cap separating from the bottle body can easily lead to infection of the cell preservation solution. Additionally, the excessively long handle of the cervical brush prevents the cap from closing properly, further increasing the risk of cell infection and affecting subsequent testing results and efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a cervical exfoliated cell preserver, which overcomes the problems of existing technology where the instruments used in the collection and preservation of cervical exfoliated cells are difficult to remove cervical cells attached to the cervical brush head, increasing the difficulty and intensity of medical staff's work. At the same time, the cervical brush is soaked in the cell preservation solution, making it difficult to close the cap, and the cap separates from the bottle, which can easily lead to infection of the cell preservation solution. Furthermore, the handle of the cervical brush is too long, making it impossible to close the cap, which can easily lead to cell infection and affect the subsequent test results and efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0008] A cervical exfoliated cell preserver was designed. The bottom and side walls of the bottle are equipped with staggered bottom scrapers and vertically distributed side scrapers. During the detachment of cervical cells from the cervical brush, the cervical cells are effectively scraped off and placed into the cell preservation solution for preservation. A break-through groove is provided on the handle of the cervical brush to effectively prevent it from being difficult to break, thus avoiding the cap not being able to close properly and affecting subsequent testing. Furthermore, the cap is connected to the bottle body by a connecting strap, preventing the risk of infection from improper cap placement. The specific design is as follows:

[0009] A cervical exfoliated cell preserver includes a bottle for holding cell preservation solution and a cervical brush for collecting cells. The bottle opening is provided with a cap, and a connecting strap is provided between the cap and the bottle.

[0010] A bottom scraper is provided on the bottom surface inside the bottle, and a side scraper is provided on the side wall inside the bottle. The cervical brush is placed inside the bottle and abuts against the bottom scraper and the side cover plate.

[0011] Preferably, the bottle body has a frustum-shaped structure that is larger at the top and smaller at the bottom. The bottle cap is threaded to the opening of the bottle body. A connecting post is provided at the center of the top of the bottle cap. One end of the connecting strip is rotatably connected to the connecting post, and the other end of the connecting strip is connected to the side wall of the bottle body.

[0012] Preferably, the cervical brush includes a handle and a brush head, the brush head being connected to the lower end of the handle, and a break-off groove being provided in the middle of the handle.

[0013] Preferably, there are at least two bottom scrapers, which are distributed alternately on the bottom surface inside the bottle, and the height of the bottom scraper is 4mm.

[0014] Preferably, there are at least two side scrapers, which are vertically distributed at equal intervals on the inner sidewall of the bottle, and the height of the side scrapers is 4mm.

[0015] Preferably, anti-slip strips are evenly spaced on the outer surface of the bottle cap.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model has interlaced bottom scrapers and vertically distributed side scrapers on the bottom and side walls of the bottle, which can assist in the process of brushing cervical cells off the cervix, so that the cervical cells can be scraped more smoothly into the cell preservation solution contained in the bottle, reducing the difficulty and intensity of medical staff's work, saving a lot of trouble for the preservation of cervical cells, and improving work efficiency.

[0018] 2. In this utility model, the cervical brush can be broken off inside the bottle to prevent cell infection and avoid inconvenience to subsequent testing. The bottle cap is sealed at the opening of the bottle to prevent infection of the cell preservation solution. At the same time, the bottle cap is connected to the bottle by a connecting strap to prevent the bottle cap from being placed randomly and contaminated with bacteria, which could lead to infection of the cell preservation solution. It is very safe, reliable and convenient to use. Attached Figure Description

[0029] like Figure 1-5As shown, this utility model provides a cervical exfoliated cell preserver, including a bottle 1 for holding cell preservation solution and a cervical brush 6 for brushing cells. A bottle cap 2 is provided at the opening of the bottle 1, which seals the opening of the bottle 1 during the preservation of cervical cells to prevent infection of the cell preservation solution. A connecting strap 3 is provided between the bottle cap 2 and the bottle 1 to prevent the bottle cap 3 from falling off or coming into contact with other objects after being opened, which could cause infection and ultimately lead to infection of the cell preservation solution. A fixing seat 22 is provided at the center of the inside of the bottle cap 2. The handle 61 of the cervical brush 6 is broken off inside the bottle 1 through a breaking groove 611, which is conducive to immersing the brush head 62 of the cervical brush 6 in the cell preservation solution without affecting subsequent testing.

[0030] A bottom scraper 5 is provided on the bottom surface inside the bottle body 1, and a side scraper 4 is provided on the side wall inside the bottle body 1. The bottom scraper 5 and the side scraper 4 can help the cervical cells on the cervical brush 6 to detach and fall into the cell preservation solution, so that the cervical cells can be better preserved in the cell preservation solution.

[0031] In the above scheme, the bottle body 1 has a frustum-shaped structure that is larger at the top and smaller at the bottom. The bottle cap 2 is threaded to the opening of the bottle body 1. A connecting post 21 is provided at the center of the top of the bottle cap 2. One end of the connecting band 3 is rotatably connected to the connecting post 21, and the other end of the connecting band 3 is connected to the side wall of the bottle body 1.

[0032] As an optimized technical solution of this utility model, the bottle cap 2 is threadedly connected to the opening of the bottle body 1, which helps to seal the opening of the bottle body 1 and prevent infection of the cell preservation fluid inside. The rotational connection between the connecting post 21 and one end of the connecting band 3 facilitates the connection of the connecting band 3, so that the opening and closing of the bottle cap 2 will not be affected during the rotation of the bottle cap 2.

[0033] In the above scheme, the cervical brush 6 includes a handle 61 and a brush head 62. The brush head 62 is connected to the lower end of the handle 61, and a break-off groove 611 is provided in the middle of the handle 61.

[0034] As an optimized technical solution of this utility model, the handle 61 is designed to facilitate hand gripping by medical personnel, the brush head 62 is made of soft bristles to facilitate brushing cervical cells, and the breakage groove 611 facilitates breaking the handle 61 so that the broken cervical brush 6 can be soaked in cell preservation solution.

[0035] In the above scheme, there are at least two bottom scrapers 5, which are distributed alternately on the bottom surface inside the bottle body 1, and the height of the bottom scraper 5 is 4mm.

[0036] As an optimized technical solution of this utility model, the bottom scraper 5 protrudes from the bottom surface of the bottle body 1, which can scrape the cervical cells from the head of the cervical brush 6 into the cell preservation solution inside the bottle body 1 for preservation. The interleaved distribution of the scraper 5 can more effectively scrape off the cervical cells.

[0037] In the above scheme, there are at least two side scrapers 4, which are vertically distributed at equal intervals on the inner side wall of the bottle body 1, and the height of the side scrapers is 4mm.

[0038] As an optimized technical solution of this utility model, the side scraper 4 protrudes from the inner side wall of the bottle body 1, which can scrape the cervical cells on the side of the cervical brush 6 into the cell preservation solution inside the bottle body 1 for preservation, so that the cervical cells on the side of the cervical brush 6 can be scraped off more smoothly.

[0039] In the above scheme, anti-slip strips 23 are equidistantly arranged on the outer surface of the bottle cap 2.

[0040] As an optimized technical solution of this utility model, an anti-slip strip 23 is provided on the outer surface of the bottle cap 2, which can play an anti-slip role when rotating to open or close the opening of the bottle body 1, so as to facilitate the opening and closing of the bottle cap 2.

[0041] Specific implementation examples:

[0042] When examining gynecological diseases, it is usually necessary to first take a sample using a cervical brush 6, then rotate to open the cap 2 at the opening of the bottle 1, hold the handle 61 of the cervical brush 6 with one hand and the bottle 1 with the other hand, and insert the brush head 62 of the cervical brush 6 into the cell preservation solution inside the bottle 1.

[0043] To facilitate the cervical cells on the cervical brush 6 falling more smoothly into the cell preservation solution, the head and sides of the brush head 62 can be placed against the bottom scraper 5 and the side scraper 4. By rotating the brush head 62 back and forth with the handle 61, the bottom scraper 5 and the side scraper 4 can be used to quickly and smoothly scrape off the cervical cells from the head and sides of the brush head 62, allowing the cervical cells to fall into the cell preservation solution.

[0044] Finally, to avoid infection of the cell preservation solution inside the bottle 1, the bottle cap 2 was tightened in time, and the handle 61 was broken through the break groove 611. The broken handle 61 with the brush head 62 was then immersed in the cell preservation solution to reduce the difficulty and intensity of the work for medical staff and to ensure that it does not affect the subsequent test results.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
