Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a novel liquid-based cell brush. Background Technology
[0002] Cervical cancer screening is an important part of women's health care. Liquid-based cytology screening requires the extensive use of cervical cell sampling brushes. Cervical cell sampling needs to be convenient, fast, and accurate. The brush needs to rotate 3-5 times around the cervical os to obtain a sufficient number of cells for testing. Currently, the sampling brushes lack indicator lines, making it difficult for doctors to determine the number of rotations. Furthermore, the outer tube of the sampling brush often becomes contaminated with secretions. After the outer tube pushes the brush head into the specimen bottle, it sometimes falls to the ground, contaminating the floor and requiring cleaning and disinfection, thus delaying the examination. Therefore, a new type of liquid-based cytology brush is needed to solve these problems. Utility Model Content
[0003] The purpose of this invention is to provide a novel liquid-based cell brush.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A novel liquid-based cell brush includes a brush head, a front rod, a rear rod, and an outer sleeve. The brush head is detachably mounted on the front rod, which is connected to the rear rod. The rear rod has an indicator line for observing the number of rotations. The outer sleeve is slidably fitted onto the front and rear rods. When in use, it is slid onto the rear rod, and after use, it is slid onto the front rod to isolate it from the outside environment.
[0006] Furthermore, the brush head is provided with a connected brush part and a sleeve part, through which cells are collected, and the front rod is provided with an insertion rod, through which the insertion rod is inserted and connected to the sleeve part.
[0007] Furthermore, the insertion rod can be a Y-shaped structure, a straight structure, a cylindrical structure, or a cross-shaped structure, and the sleeve portion is provided with an insertion hole that matches the insertion rod.
[0008] Furthermore, the indicator line is a printed, engraved, or raised mark.
[0009] Furthermore, the inner wall of the outer sleeve is provided with a slope buckle, and the rear rod is provided with multiple equally spaced slots. When the outer sleeve slides onto the rear rod, it engages with the slots through the slope buckle, thus restricting its movement.
[0010] Furthermore, the outer sleeve is made of a transparent material.
[0011] Furthermore, the front rod and the rear rod are integrally formed, and the diameter of the front rod is smaller than the diameter of the rear rod.
[0012] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0013] This invention uses an outer sleeve to protect the front rod from contact with the outside after cell collection, and an indicator line is set on the rear rod to facilitate the user's observation of the number of rotations, avoiding excessive or insufficient rotations and meeting the collection requirements.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0022] Example
[0023] Cooperate Figures 1 to 4 As shown, this utility model discloses a novel liquid-based cell brush, including a brush head 1, a front rod 2, a rear rod 3, and an outer sleeve 4. The brush head 1 is detachably mounted on the front rod 2. The front rod 2 is connected to the rear rod 3. The rear rod 3 is provided with an indicator line 5 for observing the number of rotations. The outer sleeve 4 is slidably sleeved on the front rod 2 and the rear rod 3. When in use, it is slid onto the rear rod 3. After use, it is slid onto the front rod 2 to isolate it from the outside world.
[0024] The brush head 1 is provided with a connected brush part 11 and a sleeve part 12. Cells are collected through the brush part 11. The front rod 2 is provided with an insertion rod 21, which is inserted and connected to the sleeve part 12.
[0025] The insertion rod 21 can be a Y-shaped structure, a straight structure, a cylindrical structure or a cross-shaped structure, and its structure is a cross-sectional structure. The sleeve part 12 is provided with an insertion hole that is adapted to the insertion rod 21.
[0026] The indicator line 5 is a printed, engraved, or raised mark.
[0027] The inner wall of the outer sleeve 4 is provided with a slope buckle 41, and the rear rod 3 is provided with multiple equally spaced slots 31. When the outer sleeve 4 slides onto the rear rod 3, it is engaged with the slots 31 by the slope buckle 41 to restrict its movement.
[0028] The outer sleeve 4 is made of a transparent material, such as transparent acrylic or transparent plastic. After the outer sleeve 4 is fixed to the rear rod 3, the indicator line 4 of the rear rod 3 can still be observed through its transparent structure.
[0029] The front rod 2 and the rear rod 3 are integrally formed structures, and the diameter of the front rod 2 is smaller than the diameter of the rear rod 3.
[0030] In this embodiment, the outer sleeve 4 protects the front rod 2 from contact with the outside world after cell collection, and an indicator line 5 is provided on the rear rod 3 to facilitate the user to observe the number of rotations, avoid excessive or insufficient rotations, and meet the collection requirements.
[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
