Description

Technical Field

[0001] This utility model relates to the field of throat sampling technology, and in particular to a curved swab with a sleeve for precise brushing. Background Technology

[0002] Precise, curved brush swabs play a crucial role in the diagnosis of nasopharyngeal carcinoma. These swabs, with their unique design, can flexibly bend in the complex nasopharyngeal region, reaching hard-to-reach areas for brushing. This allows for more accurate acquisition of cell samples from lesions, improving the detection rate of nasopharyngeal carcinoma. Compared to traditional swabs, curved brush swabs are more convenient to use, reducing patient discomfort. Their high-quality sample collection provides strong support for accurate pathological analysis by doctors, facilitating early detection of nasopharyngeal carcinoma, securing the best treatment opportunity for patients, and improving treatment outcomes and patient survival rates. In practical applications, curved brush swabs typically require the following techniques:

[0003] 1. For precise turning, some swabs adopt a special joint structure design, which enables turning through flexible connection parts. Others utilize special material properties, such as shape memory metal or highly elastic plastic, so that they can turn naturally under a certain external force.

[0004] 2. In terms of cell collection, the swab head usually adopts a bristle-like structure. The material, length and density of the bristles are carefully designed to improve cell collection efficiency and ensure collection results even when turning corners.

[0005] 3. In terms of material selection, medical-grade plastics and nylon are mostly used. These materials have good biocompatibility and chemical stability, and some materials also have good flexibility, making them suitable for bending operations.

[0006] 4. To prevent contamination, some swabs are equipped with sealed packaging, which can effectively isolate them from the external environment before use; some swabs also have a protective structure on the head to prevent the sample from being contaminated during the collection process.

[0007] Currently, various equipment and methods are used for corner-swab testing. Cotton swabs are relatively soft and cause less irritation to tissues, while polyester fiber swabs are more resilient, less prone to breakage, and can collect a sufficient amount of sample.

[0008] However, the above method has a significant hardware structural problem: to ensure that the curved swab can enter the testing area, the brush head is usually designed to be relatively long and thin. Therefore, the curved swab may break during movement after sampling. A broken swab may result in insufficient sample volume or damaged sample quality, affecting subsequent test results and reducing diagnostic accuracy. This application proposes a solution to this problem: a protective sleeve for the swab brush head is designed to wrap and protect the brush head, preventing breakage. Utility Model Content

[0009] (a) Technical problems to be solved

[0010] To address the shortcomings of existing technologies, this invention provides a curved brush swab with a sleeve for precise brushing, which solves the technical problem that a broken brush swab may lead to insufficient sample volume or damaged sample quality, affecting subsequent test results and reducing diagnostic accuracy.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] A precision brushing swab with a sleeve for corner inspection includes a handle and a brush head. The brush head is located at the upper end of the handle. The precision brushing swab with a sleeve for corner inspection is also provided with a head protection mechanism, including a lifting cylinder. A fixed plate is fixedly connected to the upper surface of the handle, and a rotating cylinder is rotatably connected to the upper surface of the fixed plate. The brush head is located inside the rotating cylinder, and the lower surface of the brush head is fixedly connected to the upper surface of the fixed plate.

[0014] Preferably, the inner wall of the rotating cylinder has a threaded ring with only one thread, and the rotating cylinder is fitted with a limit sleeve inside.

[0015] Preferably, the lower surface of the limiting cylinder is fixedly connected to the upper surface of the fixed plate, and a lifting cylinder is movably sleeved inside the limiting cylinder.

[0016] Preferably, a limiting groove is formed through the side surface of the limiting cylinder, and grooves are formed at both the upper and lower ends of the limiting cylinder. Both grooves are located at the left and right ends of the limiting groove, and the two grooves are also located at the upper and lower ends of the limiting groove.

[0017] Preferably, a movable ball is provided inside the limiting groove.

[0018] Preferably, one end of the moving ball is fixedly connected to the lifting cylinder, and the other end of the moving ball is located inside the threaded ring.

[0019] (III) Beneficial Effects

[0020] 1. After the swab collects a sample at a bend, the rotating cylinder is rotated. As the cylinder rotates, the moving ball is limited by the limiting groove and does not rotate with the cylinder. Therefore, as the cylinder rotates, the moving ball will rise along the trajectory of the limiting groove. The moving ball drives the lifting cylinder to rise. When the lifting cylinder rises to a certain position, it will wrap around the brush head to protect it. This prevents the brush head from breaking when the swab moves at a bend, thus ensuring that the sample quality is not compromised and the accuracy of the diagnosis remains unaffected.

[0021] 2. The two ends of the limiting groove are provided with grooves. After the lifting cylinder wraps the brush head, the moving ball is placed into the groove at the top, so that the lifting cylinder will not fall due to gravity, thus achieving the purpose of stabilizing the lifting cylinder.

[0028] This application provides a precision brushing swab with a sleeve, which effectively solves the technical problem that a broken brush swab may lead to insufficient sample volume or damaged sample quality, affecting subsequent test results and reducing diagnostic accuracy. After the brush swab collects a sample, the rotating cylinder is rotated. During the rotation of the rotating cylinder, the moving ball is limited by the limiting groove and does not rotate with the rotating cylinder. Therefore, when the rotating cylinder rotates, the moving ball will rise along the trajectory of the limiting groove. The moving ball drives the lifting cylinder to rise. When the lifting cylinder rises to a certain position, the lifting cylinder will wrap around the brush head to achieve the purpose of protecting the brush head. This prevents the brush head from breaking during the movement of the brush swab, so the sample quality will not be damaged due to breakage, and the diagnostic accuracy will not be affected.

[0029] Example

[0030] The technical solution in this application embodiment effectively solves the technical problem that a broken swab may lead to insufficient sample volume or damaged sample quality, affecting subsequent test results and reducing diagnostic accuracy. The overall approach is as follows:

[0031] To address the problems existing in the prior art, this utility model provides a precision brushing swab with a sleeve for corner inspection, including a handle 11 and a brush head 12. The brush head 12 is located at the upper end of the handle 11. This precision brushing swab with a sleeve for corner inspection also includes a head protection mechanism, including a lifting cylinder 19. A fixing plate 13 is fixedly connected to the upper surface of the handle 11, and a rotating cylinder 14 is rotatably connected to the upper surface of the fixing plate 13. The brush head 12 is located inside the rotating cylinder 14, and the lower surface of the brush head 12 is flush with the upper surface of the rotating cylinder 14. The upper surface of the fixed plate 13 is fixedly connected, and the inner wall of the rotating cylinder 14 has a threaded ring 15 with only one thread. The rotating cylinder 14 is movably fitted with a limiting cylinder 16. When the swab is used to collect a sample, the rotating cylinder 14 is rotated. When the rotating cylinder 14 rotates, the moving ball 18 is limited by the limiting groove 17 and does not rotate with the rotating cylinder 14. Therefore, when the rotating cylinder 14 rotates, the moving ball 18 will rise along the trajectory of the limiting groove 17. The moving ball 18 drives the lifting cylinder 19 to rise.

[0032] The lower surface of the limiting cylinder 16 is fixedly connected to the upper surface of the fixed plate 13. The lifting cylinder 19 is movably sleeved inside the limiting cylinder 16. A limiting groove 17 is opened through the side surface of the limiting cylinder 16. Grooves are opened at both the upper and lower ends of the limiting cylinder 16. The two grooves are located at the left and right ends of the limiting groove 17, and the two grooves are also located at the upper and lower ends of the limiting groove 17. When the lifting cylinder 19 rises to a certain position, the lifting cylinder 19 will wrap around the brush head 12 to protect the brush head 12. This prevents the brush head 12 from breaking when the swab moves around a bend. Therefore, the sample quality will not be damaged due to breakage, and the accuracy of the diagnosis will not be affected.

[0033] The limiting groove 17 is provided with a movable ball 18. One end of the movable ball 18 is fixedly connected to the lifting cylinder 19, and the other end of the movable ball 18 is located inside the threaded ring 15. The two ends of the limiting groove 17 are provided with grooves. When the lifting cylinder 19 wraps the brush head 12, the movable ball 18 is placed in the upper groove so that the lifting cylinder 19 will not fall due to gravity, thus achieving the purpose of stabilizing the lifting cylinder 19.

[0034] Working principle:

[0035] After the swab collects a sample at a bend, the rotating cylinder 14 is rotated. As the rotating cylinder 14 rotates, the moving ball 18 is limited by the limiting groove 17 and does not rotate with the rotating cylinder 14. Therefore, as the rotating cylinder 14 rotates, the moving ball 18 will rise along the trajectory of the limiting groove 17. The moving ball 18 drives the lifting cylinder 19 to rise. When the lifting cylinder 19 rises to a certain position, it will wrap around the brush head 12 to protect it. This prevents the brush head 12 from breaking when the swab moves at a bend, thus ensuring that the sample quality is not damaged by breakage and that the accuracy of the diagnosis is not affected. The limiting groove 17 has grooves at both ends. After the lifting cylinder 19 wraps around the brush head 12, the moving ball 18 is placed in the upper groove, preventing the lifting cylinder 19 from falling due to gravity and ensuring its stable placement.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
