Description

Technical Field

[0001] This utility model relates to the field of medical sampling technology, and in particular to a medical sampling cell brush. Background Technology

[0002] Cell sampling brushes are primarily used in clinical settings. Healthcare professionals can use the brush to probe inside the affected area or on the surface of tissue, and gently brush to collect cell samples for subsequent pathological examinations, cell analysis, or other laboratory tests to help doctors diagnose or assess the patient's condition.

[0003] Most existing cell brushes consist of a handheld handle and a sampling section at the end of the handle. During use, the sampling section is inserted into the affected area to collect a sample. However, the diameter and roughness of the sampling section are much larger than the handheld handle. If the sampling location is sensitive or the depth is deep, the sampling section can irritate the affected area. Furthermore, the sampling section is exposed throughout the insertion and removal process, and may be contaminated by cells from other locations before and after sampling, leading to decreased accuracy of subsequent test results. There is also a possibility that the sampled cells may detach and be replaced by cells from other locations during the removal process. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a medical sampling cell brush that solves the problem of sample contamination caused by cells from other locations when the brush is pulled out after sampling.

[0005] The technical solution of this utility model is as follows: a medical sampling cell brush, including an outer tube body, the inner tube body having a cavity through both ends, an inner rod with a length greater than the outer tube body and a diameter smaller than the inner diameter of the outer tube body inserted inside the outer tube body, a rubber ring provided at the top of the outer tube body, a ball head provided at the top of the inner rod extending through the rubber ring, the diameter of the ball head being greater than the inner diameter of the rubber ring, a plurality of sampling plates distributed in a ring on the top surface of the inner rod, and a handheld plate provided at the bottom of the inner rod.

[0006] Furthermore, both the outer tube and the inner rod are made of medical-grade rubber material. The inner rod, located inside the outer tube, forms an internal support within the outer tube. The inner rod supports the outer tube and keeps it vertical without bending, ensuring that the outer tube has sufficient support force to prevent its structure from deforming as it wraps around the inner rod and approaches the affected area.

[0007] Furthermore, both the rubber ring and the ball head are made of flexible medical rubber material. The inner diameter of the rubber ring is smaller than the inner diameter of the outer tube, and the diameter of the ball head is adapted to the inner diameter of the outer tube, ensuring that the ball head will not pass through the rubber ring and that the ball head can be used to seal the outer tube by engaging with it.

[0008] Furthermore, the sampling piece is V-shaped with both ends connected to the inner rod, and the bent part of the sampling piece abuts against the inner wall of the outer tube. Several sampling pieces form a spindle-shaped sampling area on the surface of the inner rod.

[0009] Furthermore, the sampling sheet includes an internal support core and a sampling layer wrapped around the support core. The support core is made of flexible plastic, and the sampling layer is made of non-woven fabric with fine protrusions on its surface. This provides the sampling sheet with a certain degree of support while ensuring that the sampling sheet can be deformed and has sufficient sampling effect.

[0010] Furthermore, the length of the spindle-shaped sampling area formed by the sampling piece is adapted to the inner rod being longer than the outer tube.

[0011] Furthermore, the surface of the handheld piece is provided with a rough texture.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model firstly wraps the inner rod with the outer tube, and at the same time, the ball head at the top of the inner rod covers the end of the outer tube, making the end of the outer tube smooth as a whole. This ensures that the overall structure is smooth and non-irritating when close to the affected area, improving the patient's comfort. At the same time, the ball head seals the outer tube, ensuring that the sampling piece inside the outer tube will not be contaminated when close to the affected area.

[0014] 2. When using this utility model, after the outer tube is close to the affected area, the inner rod can be pushed by the handpiece. After the other end of the inner rod is pushed out of the outer tube, the sampling piece is exposed outside the outer tube and thus close to the affected area. At this time, the operator can control the inner rod by the handpiece to make the sampling piece contact the affected area for sampling. After sampling is completed, the inner rod can be pulled by the handpiece to make the sampling piece return to the outer tube and restore the closed state of the outer tube. Then, the outer tube is pulled out of the affected area along with the inner rod. During this process, the sampling piece will not come into contact with other parts, thus avoiding contamination of the sampling piece. Attached Figure Description

[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] like Figure 1-3 As shown, a medical sampling cell brush includes an outer tube 1 with a cavity extending through both ends. An inner rod 2, longer than the outer tube 1, is inserted inside the outer tube 1. Both the outer tube 1 and the inner rod 2 are made of medical rubber material. The inner rod 2, located inside the outer tube 1, forms an internal support within the outer tube 1. The inner rod 2 supports the outer tube 1 to always remain vertical and prevent bending, ensuring that the outer tube 1 has sufficient support force to prevent its own structure from deforming as it wraps around the inner rod 2 and approaches the affected area. The diameter of the inner rod 2 is smaller than the inner diameter of the outer tube 1.

[0021] A rubber ring 3 is provided at the top of the outer tube 1, and a ball head 4 is provided at the top of the inner rod 2 that extends through the rubber ring 3. Both the rubber ring 3 and the ball head 4 are made of flexible medical rubber material. The inner diameter of the rubber ring 3 is smaller than the inner diameter of the outer tube 1, and the diameter of the ball head 4 is adapted to the inner diameter of the outer tube 1 to ensure that the ball head 4 will not pass through the rubber ring 3. This ensures that the ball head 4 can block the outer tube 1 by cooperating with it. The diameter of the ball head 4 is larger than the inner diameter of the rubber ring 3. Several sampling pieces 5 are distributed in a ring on the top surface of the inner rod 2.

[0022] The sampling piece 5 is V-shaped and connected to the inner rod 2 at both ends. The bent part of the sampling piece 5 abuts against the inner wall of the outer tube 1. Several sampling pieces 5 form a spindle-shaped sampling area on the surface of the inner rod 2. The sampling piece 5 includes an inner support core and a sampling layer wrapped around the support core. The support core is made of flexible plastic, and the sampling layer is made of non-woven fabric with fine protrusions on the surface. This gives the sampling piece 5 a certain degree of support while ensuring that the sampling piece 5 can be deformed and has sufficient sampling effect. The length of the spindle-shaped sampling area formed by the sampling pieces 5 is adapted to the inner rod 2 being longer than the outer tube 1. A handheld piece 6 is provided at the bottom of the inner rod 2, and the surface of the handheld piece 6 is provided with rough texture.

[0023] The working principle of this utility model is as follows: First, when using it, the operator pulls the handpiece 6 outward to move the inner rod 2 and the ball head 4 at the end of the inner rod 2, ensuring that the ball head 4 fits with the rubber ring 3 to seal the outer tube 1. Then, the operator holds the outer tube 1 and inserts the end close to the affected area. At this time, the operator pushes the inner rod 2 with the handpiece 6. During the movement of the inner rod 2, the sampling piece 5 moves away from the outer tube 1. After the sampling piece 5 on the surface of the inner rod 2 leaves the outer tube 1, the operator can move the inner rod 2 with the handpiece 6 to bring the sampling piece 5 to the affected area for sampling. After the sampling is completed, the operator pulls the inner rod 2 again with the handpiece 6 to bring the sampling piece 5 back into the outer tube 1, ensuring that the ball head 4 at the end of the inner rod 2 fits with the rubber ring 3, and the outer tube 1 is sealed by the ball head 4. Then, the entire structure is taken out outward. During the removal process, the sampling piece 5 will not come into contact with the external environment, thus avoiding contamination of the sampling piece 5.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
