Description

Technical Field

[0001] This utility model belongs to the field of cervical sampling, specifically relating to a multi-range gynecological cell sampler and sample box. Background Technology

[0002] Cervical cytology is the most basic method for screening for cervical lesions. It's a thin-layer liquid-based cytology test (TCT) performed during a gynecological exam. The doctor uses a small brush to collect cells from the cervix, which are then analyzed using images and computer-aided methods to detect abnormal cervical cells at an early stage. HPV testing is similar to cytology; it also uses a small brush to collect samples of cervical tissue and secretions to detect the presence of the HPV virus.

[0003] Existing gynecological sampling brushes used for TCT and HPV pathology testing can only sample one location at a time. If multiple locations need to be screened, different sampling brushes must be used to sample each location individually. This method is not only wasteful of materials, but also cumbersome for both doctors and patients. In addition, the area around the cervix is ​​dome-shaped, and existing single-brush sampling brushes have difficulty reaching this dome, leading to missed detections during cervical screening. Furthermore, the small sampling point on the vaginal wall can also result in missed detections. Therefore, a multi-range gynecological cell sampler and sample box are proposed to solve the above-mentioned problems. Utility Model Content

[0006] The base plate is located at the end of the grip.

[0007] A plug rod is mounted on the base plate; the outer wall of the top end of the plug rod has two insertion shafts.

[0008] The side sampling component and the top sampling component are detachably mounted on the insertion rod;

[0009] The upper sampling component includes an upper brush head, which is crown-shaped with two wings protruding to the sides and the bristles in the middle being longer than the wings.

[0010] Furthermore, the side sampling component includes a sleeve fitted onto the outer wall of the insertion rod; and side brush heads disposed on both sides of the sleeve.

[0011] Furthermore, the upper sampling component also includes a connecting sleeve fitted on the upper part of the insertion rod. The upper end of the connecting sleeve is hinged to the upper brush head, and the lower end extends outward to form a skirt. The outer wall of the connecting sleeve is provided with a guide groove for the insertion shaft to slide. The guide groove is L-shaped and the inner wall of the horizontal part has a triangular protrusion.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This embodiment provides a multi-range gynecological cell sampler, including a handle 1;

[0028] Base plate 2 is located at the end of handle bar 1;

[0029] Insert rod 3 is mounted on base plate 2; the outer wall of the top end of insert rod 3 has two insertion shafts 4;

[0030] The side sampling component 5 and the top sampling component 6 are detachably mounted on the insertion rod 3;

[0031] The upper sampling component 6 includes an upper brush head 61, which is crown-shaped with two wings protruding to the sides and the bristles in the middle being longer than the wings.

[0032] In this embodiment, before use, the side sampling component 5 and the upper sampling component 6 need to be assembled onto the insertion rod 3. When sampling is required, the vagina can be dilated by opening the speculum. Then, the sampling head is inserted into the patient's vagina by holding the insertion rod 3. When the upper brush head 61 contacts the cervix, the middle protruding part can sample the cervical opening, while the two wings can sample the fornix near the cervical opening at the same time. After sampling the cervix, the speculum is withdrawn, and the side sampling component 5 is rotated several times in the vagina to collect the vaginal sample. After taking a sample from the vagina, the entire sampler can be removed. With the side sampling component 5 and the upper brush head 61, samples can be taken from the cervix, the fornix of the cervix, and the vagina at the same time. Compared with the existing technology, this not only reduces material consumption but also greatly simplifies the sampling process. At the same time, since the two wings of the upper brush head 61 protrude to both sides and the middle bristles are longer than the two wings, the protruding wings can reduce the probability of the middle bristles (cervical sample) contacting the vaginal wall, thus improving the positive rate of TCT to a certain extent.

[0033] Specifically, refer to Figure 2 and Figure 4 The side sampling component 5 includes a sleeve 51 fitted onto the outer wall of the insertion rod 3; and side brush heads 52 disposed on both sides of the sleeve 51.

[0034] In this embodiment, before use, the sleeve 51 can be placed on the outer wall of the insertion rod 3, the bottom plate 2 can limit the bottom of the sleeve 51, and the side brush heads 52 provided on both sides can sample the vaginal wall.

[0035] Specifically, refer to Figure 2-3 The upper sampling component 6 also includes a connecting sleeve 62 sleeved on the upper part of the insertion rod 3. The upper end of the connecting sleeve 62 is hinged to the upper brush head 61, and the lower end extends outward to form a skirt 63. The outer wall of the connecting sleeve 62 is provided with a guide groove 64 for the insertion shaft 4 to slide. The guide groove 64 is L-shaped and the inner wall of the horizontal part has a triangular protrusion 65.

[0036] In this embodiment, after assembling the sleeve 51, the connecting sleeve 62 can be fitted onto the end of the insert rod 3 and the insert shaft 4 can be placed in the guide groove 64. When the insert shaft 4 slides to the maximum position, the connecting sleeve 62 is rotated so that the insert shaft 4 slides in the horizontal part on the guide groove 64. When the insert shaft 4 passes the triangular protrusion 65, it will squeeze the triangular protrusion 65 and deform it. After passing through the triangular protrusion 65, the triangular protrusion 65 rebounds and limits the return direction of the insert shaft 4, thereby fixing the connecting sleeve 62 on the insert rod 3 and completing the assembly of the upper brush head 61. At this time, the skirt 63 will limit the top of the sleeve 51, thereby fixing the sleeve 51 and the side brush head 52.

[0037] Specifically, the bristles on both the side brush head 52 and the top brush head 61 have barbs.

[0038] In this embodiment, the bristles on the side brush head 52 and the upper brush head 61 have a barb design. Through the resulting capillary effect, the adhesion between the sample and the bristles can be improved, thereby increasing the success rate of sample extraction.

[0039] Specifically, refer to Figure 4 The inner wall of the sleeve 51 is provided with a limiting strip 7; the insert rod 3 is provided with a limiting groove 8 for the limiting strip 7 to slide.

[0040] In this embodiment, when the sleeve 51 is fitted over the insert rod 3, the limiting strip 7 is inside the limiting groove 8. Through the slot cooperation between the two, the sleeve 51 and the side brush head 52 can be prevented from rotating or loosening during sampling, thereby improving the stability of use.

[0041] Specifically, refer to Figure 6-7 The outer wall of the upper brush head 61 is fitted with an umbrella-shaped film 9 for isolation.

[0042] In this embodiment, the umbrella-shaped film 9 on the outer wall of the upper brush head 61 will adhere to the vaginal cavity at its edges during the insertion of the sampler into the vagina. When the sampler is inserted into the vagina, the umbrella-shaped film 9 will expose the upper brush head 61 under the traction of the upper brush head 61 for sampling. Conversely, when the sampler is pulled out, the umbrella-shaped film 9 will invert and cover the upper brush head 61, thereby protecting the upper brush head 61 and further avoiding the possibility of sample contamination.

[0043] On the other hand, refer to Figure 5 The present invention also provides a box body 101 and a box cover 102, wherein the box body 101 and the box cover 102 are hinged together; the box body 101 has two cavities 103 inside.

[0044] In this embodiment, after sampling is completed, the sleeve 51 and the upper brush head 61 can be disassembled and the sleeve 51 together with the side brush head 52 and the upper brush head 61 can be placed into the two cavities 103 respectively and the box cover 102 can be closed. By storing the samples in isolation, the possibility of cross-contamination of the samples can be avoided.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
