Description

Technical Field

[0001] This utility model relates to the field of cell brushes, and more particularly to an adjustable disposable cell brush. Background Technology

[0002] A disposable cell brush is a medical or research tool specifically designed for cell sampling. It typically consists of a handle and a brush head and is discarded after a single cell collection operation, making it non-reusable. Currently, most disposable cell brushes use simple plug-in or adhesive connections between the brush head and handle. During sampling, when scraping or agitating cells is required, the brush head is prone to loosening due to external forces.

[0003] Secondly, some disposable cell brushes have a one-piece brush head and handle structure, which makes it impossible to flexibly replace the brush head according to different sampling needs. For example, existing brush heads may not be well adapted when collecting samples from sampling tubes with different aperture sizes or for sampling sites of different shapes. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable disposable cell brush that facilitates the replacement and disassembly of the brush head and the adjustment of the brush handle length.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An adjustable disposable cell brush includes a brush handle and a brush head. The brush handle is a long strip structure. One end of the brush handle is provided with a connector. An embedding groove is opened on the surface of the connector. The other end of the brush handle is used for operation and force application. One end of the brush handle is provided with a brush head. The end of the brush head is provided with an embedding head. The shape of the embedding head matches the embedding groove, and the embedding head is engaged in the embedding groove.

[0006] Preferably, the shape of the insert head gradually widens from the brush head to the brush handle, which enhances the locking stability between the insert head and the insert groove, prevents the brush head from loosening or falling off due to external force during the sampling process, and ensures the smooth progress of the sampling operation.

[0007] Preferably, the outer surface of the brush handle has strip-shaped grooves distributed in an equidistant ring array, which increases the contact area and friction between the fingers and the brush handle, allowing the operator to hold the brush handle more firmly, reducing errors caused by hand slippage during operation, and improving the stability and accuracy of operation.

[0008] Preferably, the outer side of the brush handle is provided with annular break grooves at equal intervals, which provides a clear break position, making it easy for the operator to accurately break the brush handle. At the same time, the design of the annular break grooves makes the breaking process easier and smoother, reducing burrs and debris generated during the breaking process.

[0009] Preferably, the brush handle includes a wide diameter section and a narrow diameter section. The wide diameter section provides a gripping area, and the narrow diameter section is used to connect the brush head. A soft sleeve is slidably fitted on the outside of the narrow diameter section. The wide diameter section is easy for the operator to grip, and the narrow diameter section is connected to the brush head. The sliding design of the soft sleeve further enhances the firmness of the connection between the brush head and the brush handle, preventing the brush head from loosening.

[0010] Preferably, the wide diameter section and the narrow diameter section are integrally molded, which eliminates the connection gap between the wide diameter section and the narrow diameter section, and improves the overall strength and stability of the brush handle.

[0011] Preferably, the cross-section of the annular fracture groove is V-shaped. The V-shaped cross-section of the annular fracture groove can more effectively guide the fracture process, making the fracture easier and more accurate.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This utility model enables easy replacement of the brush head in a short time by engaging the insertion head at the end of the brush head with the insertion groove of the brush handle connector. When facing cell sampling at different locations, different sample types, or when it is necessary to replace worn brush heads, no complicated tools are needed, which improves sampling efficiency. External force can be applied along the annular break groove to break the brush handle at the break groove, thereby adjusting the effective length of the brush handle. By adjusting the length of the brush handle, the cell brush can adapt to the sampling needs at different depths.

[0014] 2. The soft sleeve of this utility model can cover the snap-fit ​​part between the brush head and the brush handle by sliding, which further enhances the firmness of the connection. During the sampling operation, the soft sleeve can play a buffering and reinforcing role, improve the reliability and durability of the product, and reduce the risk of sampling failure due to connection problems.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 3 This embodiment provides an adjustable disposable cell brush, including a brush handle 1 and a brush head 4. The brush handle 1 has a long strip structure. One end of the brush handle 1 is provided with a connector 2. The surface of the connector 2 is provided with an embedding groove 3. The other end of the brush handle 1 is used for operation and force application. One end of the brush handle 1 is provided with a brush head 4. The end of the brush head 4 is provided with an embedding head 5. The shape of the embedding head 5 matches the embedding groove 3, and the embedding head 5 is snapped into the embedding groove 3.

[0021] By pressing, the insert head 5 can be snapped into the insert groove 3, enabling quick connection and disassembly of the brush head 4 and the brush handle 1. The brush head 4 is a disposable component, while the brush handle 1 is a reusable component. The cell brush can be used multiple times by replacing the brush head 4, ensuring hygiene and safety for each use. It also facilitates the replacement of different shaped brush heads 4 to meet different examination needs, such as broom-shaped brush head 4 and pagoda-shaped brush head 4. The broom-shaped brush head 4 has bristles distributed in a broom shape and is suitable for cervical liquid-based cytology examination; the pagoda-shaped brush head 4 has bristles distributed in a cone or pagoda shape and is suitable for HPV virus detection.

[0022] The shape of the insert head 5 gradually widens from the brush head 4 toward the brush handle 1. The insert head 5 is first inserted into the entrance of the insert groove 3. By pressing, the insert head 5 is pushed into the insert groove 3. Its gradually widening shape can form a tighter fit with the insert groove 3.

[0023] The outer surface of the brush handle 1 is provided with strip-shaped grooves 6 arranged in an equidistant ring. When the operator holds the brush handle 1, the embedded strip-shaped grooves 6 increase the contact area and friction between the fingers and the brush handle 1, allowing the operator to hold the brush handle 1 more firmly.

[0024] The outer side of the brush handle 1 is provided with annular break grooves 7 at equal intervals. When it is necessary to break the brush handle 1 to adapt to different usage scenarios or to facilitate sample processing, the operator can apply external force along the annular break grooves 7 to break the brush handle 1 at the break groove, thereby adjusting the effective length of the brush handle 1. By adjusting the length of the brush handle 1, the cell brush can adapt to the sampling needs of different depths, such as sampling of the cervix, vagina or oral cavity, improving the flexibility and applicability of the operation.

[0025] The brush handle 1 includes a wide diameter portion 11 and a narrow diameter portion 12. The wide diameter portion 11 provides a gripping area, and the narrow diameter portion 12 is used to connect the brush head 4. A soft sleeve 8 is slidably fitted on the outer side of the narrow diameter portion 12. When the embedding groove 3 on the connector 2 is engaged with the embedding head 5 of the brush head 4, the operator can drag the soft sleeve 8 along the narrow diameter portion 12 to make it fit the position where the embedding groove 3 and the embedding head 5 are engaged. After the soft sleeve 8 fits the engagement position, it applies a certain pressure to the connection between the embedding groove 3 and the embedding head 5 through its elasticity, thereby enhancing the connection between the brush head 4 and the brush handle 1 and preventing the brush head 4 from loosening or falling off due to external force during the sampling process.

[0026] The wide diameter section 11 and the narrow diameter section 12 are integrally formed. They are molded in one step during the production process, making the wide diameter section 11 and the narrow diameter section 12 a whole. This facilitates processing and reduces the failure of the brush handle 1 caused by loosening or breakage of the connection parts.

[0027] The cross-section of the annular break groove 7 is V-shaped. When an external force is applied to break the brush handle 1, the V-shaped break groove can concentrate the stress at the bottom of the groove. As the external force increases, the stress gradually increases, eventually causing the brush handle 1 to break at the break groove.

[0028] 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.
