Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to an oral mucosa sampling device. Background Art

[0002] When taking oral mucosal samples, the sampler wears gloves, takes out a cotton swab, inserts it into the subject's mouth, and rotates and scrapes the inner wall of the oral cheek 30 times on each side. A sample needs to be taken on each side. When sampling, the cotton swab cannot touch other parts of the mouth, otherwise it will be necessary to take a new cotton swab for sampling. If the patient accidentally opens and closes his mouth during this process, the cotton swab will be touched, and then the cotton swab will need to be taken again for sampling.

[0003] Chinese patent announcement number CN215503165U, publication date 20220114, discloses an oral mucosal sampling device for medical testing, including a drive box, a positive and negative threaded rod is rotatably connected between the top and bottom of the inner cavity of the drive box through a bearing, the upper and lower positions of the outer surface of the positive and negative threaded rod are threadedly connected with sleeves, the left side of the sleeve is fixedly connected with a drive plate, the upper and lower positions of the left side of the drive box are slidably connected with an L-shaped plate, and the left side of the drive plate passes through the drive box and is fixedly connected to the connection between the L-shaped plate.

[0004] The above-mentioned existing oral mucosa sampling device can facilitate the movement of the arc plate to support the oral cavity by providing a drive box, positive and negative threaded rods, a sleeve, a drive plate, an L-shaped plate, an arc plate and a drive disk. In the specific implementation process, the above-mentioned device can often only maintain the opening of the oral cavity. When it comes to the sampling step, the operator is still required to hold the rod body of the cotton swab with one hand and rotate the rod body with the other hand. The overall operation is relatively inconvenient. Therefore, it is urgent to propose a corresponding oral mucosa sampling device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an oral mucosa sampling device in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An oral mucosa sampling device comprises a base frame, which is a rectangular structure. Both sides of the vertical end of the base frame are fixedly connected to fixed sleeves, and the back surfaces of two groups of the fixed sleeves are fixedly installed with horizontal frames through vertical rods. The opposite surfaces of the two groups of the fixed sleeves are rotatably connected to a rotating seat through a first bearing. The inner surface wall of the rotating seat is rotatably connected to a rotating rod through a second bearing. A fixing component for fixing a cotton swab is arranged inside the rotating rod.

[0008] Preferably, the cross section of the vertical rod is a rectangular structure, the vertical groove vertically arranged on the outer wall of the vertical rod is slidably connected to the inner wall of the fixing sleeve, and the inner wall of the fixing sleeve is provided with a positioning portion for positioning the vertical rod.

[0009] Preferably, the positioning portion comprises a positioning rod, an outer wall of the positioning rod is screwed to an inner wall of the fixing sleeve, and an open end of the positioning rod abuts against an outer wall of the vertical rod.

[0010] Preferably, the interior of the rotating seat is provided with hollowing, and the outer wall of the rotating rod is provided with rough texture.

[0011] Preferably, the two groups of horizontal frames and the vertical rods are integrally formed, and the back surfaces of the two groups of horizontal frames are fixedly connected with silicone pads.

[0012] Preferably, the fixing assembly comprises a locking rod, and the outer wall of the locking rod is screwedly connected to the inner wall of the rotating rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the present application, the rod body of the cotton swab is inserted into the interior of the rotating rod, and the locking rod is rotated. The locking rod is screwed with the inner surface wall of the rotating rod until the open end of the locking rod abuts against the outer surface wall of the rod body, thereby fixing the rod body through friction. Then the two sets of cross frames are placed in the patient's mouth, and the patient's teeth are bitten on the silicone pad. At this time, the sampling device remains stable, and the operator can deflect the rotating rod, and the rotating rod rotates with bearing one as the axis until the cotton swab abuts against the inner wall of the cheek. At this time, the rotating rod one bearing two is rotated as the axis. After completing the specified number of rotations, the group of cotton swabs is replaced and the above operation is repeated, thereby ensuring the stability of the sampling process while improving the convenience of the sampling process.

[0015] 2. In the present application, the positioning rod is rotated to make its open end separate from the outer wall of the vertical rod. At this time, the vertical rod loses its restraining force. Then, the vertical rod is moved vertically until the spacing between the two sets of horizontal frames reaches the specified requirement. The positioning rod is then rotated in the opposite direction, and the positioning rod is screwed into the inner wall of the fixing sleeve until the open end of the positioning rod abuts against the outer wall of the vertical rod. In this way, the vertical rod and the fixing sleeve are re-fixed by friction, so that the spacing between the two sets of horizontal frames can be conveniently adjusted according to usage requirements.
