AI Technical Summary
Existing cervical sampling devices are prone to slipping when the sampling swab brush is broken, making it difficult to break and affecting sampling efficiency.
A sample bottle with a triangular brush head and a folding bar tooth was designed. The brush bar has an annular folding bar groove, and the bottle cap has an internal thread and an annular pressing bevel. Combined with the external thread and anti-slip texture, the brush bar can be positioned and broken quickly.
Through improved design, stable breakage of the brush rod was achieved, improving sampling efficiency and sampling effect while reducing operational difficulty.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of gynecological sampling tools, specifically to a cervical sampling device. Background Technology
[0002] Currently, when diagnosing cervical diseases, it is usually necessary to collect cervical secretions for testing. This requires the use of cervical sampling swabs. After the cervical sampling swab is collected, it needs to be placed in a sample bottle. The upper part of the cervical sampling swab is broken off and left in the sample bottle. The breaking method usually involves pressing the bottle cap tightly against the sampling swab brush rod, and then flipping the brush rod up and down to break it. However, because the mouth of the existing sample bottle is smooth, it is easy to slip when flipping the brush rod, making it difficult to break. Utility Model Content
[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a cervical sampling device.
[0004] This utility model includes a cervical brush and a sample bottle. After sampling, the cervical brush is placed in the sample bottle, and the broken cervical brush head is left in the sample bottle. The cervical brush includes a brush handle and a brush head. The brush head is triangular and has bristles at the top. The brush head is mounted on the brush handle. The sample bottle includes a bottle body and a bottle cap. A set of folding teeth is arranged in a ring at the mouth of the bottle body.
[0005] The upper part of the brush handle has a set of annular folding grooves.
[0006] The bristles bulge upwards in the middle, forming a cervical-like shape.
[0007] The brush head has a triangular weight-reducing hole in the middle.
[0008] The upper outer wall of the bottle body is provided with external threads, and the inner wall of the bottle cap is provided with internal threads. The bottle cap is threadedly installed on the bottle body.
[0009] A limit ring is provided below the external thread of the bottle.
[0010] The bottom of the bottle cap has a ring-shaped pressing bevel.
[0011] The outer wall of the bottle cap has a grid-like anti-slip texture.
[0012] The bristles are made of silicone.
[0013] The outer wall of the brush handle is textured with anti-slip patterns.
[0014] The advantages of this invention are: the bottle mouth is equipped with serrated teeth, which can position the brush rod when it is broken, preventing it from slipping and allowing for fast breaking. The brush head is triangular, matching the shape of the bristles, resulting in a moderate length of bristles in the middle and better sampling effect. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0022] In the description of the embodiments of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0023] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0024] As shown in the attached figure, this utility model includes a cervical brush and a sample bottle. After sampling, the cervical brush is placed in the sample bottle, and the broken head of the cervical brush is left in the sample bottle. The cervical brush includes a brush handle 1 and a brush head 2. The brush head 2 is triangular and has bristles 3 on the top. The brush head 2 is mounted on the brush handle 1. The sample bottle includes a bottle body 4 and a bottle cap 5. A set of folding teeth 6 is arranged in a ring at the mouth of the bottle body 4.
[0025] The brush handle 1 has a set of annular folding grooves 7 on its upper part. Multiple annular folding grooves 7 can increase the area of the breakable area, so there is no need to deliberately align the folds during use.
[0026] The middle of the bristles 3 bulges upwards, forming a cervical-like shape.
[0027] A triangular weight-reducing hole 8 is opened in the middle of the brush head 2. This reduces the weight of the brush head 2.
[0028] The upper outer wall of the bottle body 4 is provided with external threads, and the inner wall of the bottle cap 5 is provided with internal threads. The bottle cap 5 is threadedly installed on the bottle body 4.
[0029] A limit ring 9 is provided below the external thread of bottle body 4 to limit the maximum knob position of bottle body 4.
[0030] The bottom of the bottle cap 5 is provided with a ring-shaped pressing bevel 10.
[0031] The outer wall of the bottle cap 5 is provided with a grid-like anti-slip texture 11.
[0032] The bristles 3 are made of silicone. The silicone material reduces pain during sampling.
[0033] The outer wall of brush handle 1 is provided with anti-slip texture. The brush handle has a better grip and is easier to rotate.
[0034] Example 1: Medical staff hold the brush handle 1 and insert the brush head 2 into the vagina, rotating it at the cervix to collect samples. After sampling, the brush head 2 is placed into the bottle body 4, with the brush handle 1 located in the groove of the folding rod tooth 6. Then, the bottle cap 5 is placed on top of the bottle body 4, and the bottle cap 5 is pressed down. The annular pressing bevel 10 is pressed tightly onto the annular folding rod groove 7 of the brush handle 1. Then, the brush handle 1 is folded up and down to break it off, and the brush head 2 is stored inside the bottle body 4. The bottle cap 5 is then screwed on to seal the upper part of the bottle body 4.
