Description

Technical Field

[0001] This invention relates to the field of medical testing technology, specifically to an oral mucosal scraping device. Background Technology

[0002] When performing bilateral buccal mucosal sampling, especially in cancer screening and high-risk population monitoring, it is often necessary to combine up-and-down scraping with rotating the swab or scraper to improve sampling efficiency. Because the surface of the buccal mucosa is relatively smooth, simple up-and-down scraping is insufficient to ensure adequate acquisition of deep cells. Rotation, on the other hand, allows for more even collection of cells from different areas, avoiding sample heterogeneity. This method is particularly suitable for high-quality sampling scenarios, such as early cancer screening, ensuring the acquisition of comprehensive and reliable samples.

[0003] However, during the scraping of both buccal mucosa, the prolonged operation time causes the masticatory muscles of the patient to be under tension for an extended period, easily leading to soreness and discomfort. Especially during multiple extractions, the extended mucosal exposure time causes oral muscle fatigue, consequently affecting the patient's comfort and cooperation. Therefore, reducing discomfort and improving patient acceptance during prolonged sampling has become a problem that needs to be addressed.

[0004] Secondly, the fatigue of staff due to repeated scraping actions directly affects the scraping quality and negatively impacts the amount of cell samples collected. Especially in high-frequency sampling, the accuracy and stability of manual operation are difficult to maintain, thus affecting laboratory testing results and efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an oral mucosal scraping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oral mucosa scraping device, comprising a housing, wherein the housing is provided with an operating structure capable of simultaneously scraping the buccal mucosa of both sides of the oral cavity; the operating structure comprises: two supports, respectively disposed on both sides inside the housing, each support having a pair of opposing support rods; a sleeve rod, rotatably connected to the axis of the support rods, each sleeve rod having an elastic rope, one end of the elastic rope being fixed to the support, and a connecting rope between the two sleeve rods; a rotating rod, rotatably disposed within the sleeve rod, the rotating rod having a scraping rod disposed inside; a rope adjustment mechanism, disposed within the housing, for changing the state of the elastic rope; and a transmission mechanism, disposed within the housing, for providing power to the rotating rod.

[0007] Preferably, the rope adjustment mechanism includes: a shaft passing through the housing, the shaft having a through hole for the connecting rope to pass through, and a first magnetic block and a second magnetic block on the shaft; and a pair of third magnetic blocks disposed on the housing.

[0008] Preferably, the end of the rotating rod is tapered, and the housing is provided with two opposing sliding grooves. The transmission mechanism includes: a fixed frame slidably disposed in the sliding grooves; a first pressure frame and a second pressure frame, the first pressure frame and the second pressure frame being disposed in the fixed frame, a spring being provided between the first pressure frame and the second pressure frame, and both the first pressure frame and the second pressure frame having two opposing friction surfaces; and a pair of pressure rods, respectively disposed on the first pressure frame and the second pressure frame.

[0009] Preferably, the fixed frame has sliding plates at both ends that are slidably connected to the housing.

[0010] Preferably, each of the sliding plates is provided with a push plate, and a friction rubber pad is provided between the push plate and the housing.

[0011] Preferably, the housing has an opening, and the opening has a cover to facilitate the movement of the sleeve rod.

[0012] Preferably, the cover includes: a cover body disposed at the opening, the cover body having two through holes, the through holes having an elastic movable membrane; and a fixing ring disposed on the movable membrane, the fixing ring being fixedly connected to the sleeve rod.

[0013] Preferably, the active film is made of natural latex.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By designing a double-rod structure, this device can simultaneously scrape the buccal mucosa on both sides, effectively improving sampling efficiency. Combined with an elastic rope, connecting rope, and rope adjustment mechanism, the scraping rod can flexibly extend and automatically open within the oral cavity, reducing the required mouth opening and making it more suitable for individuals with smaller mouths. Furthermore, the transmission mechanism triggers the scraping rod's rotation by pressing, replacing the traditional manual rotation method. This not only makes operation smoother but also effectively improves the comfort of the person being sampled, reducing discomfort, while also reducing the operator's workload and fatigue.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] Example Please see Figure 1-8 As shown, the present invention provides an oral mucosa scraping device, including a housing 1, and an operating structure 2 inside the housing 1 that can simultaneously scrape the buccal mucosa of both sides of the oral cavity. like Figure 2 and Figure 3 As shown, the operating structure 2 includes: two supports 201, a support rod 202, a sleeve rod 203, an elastic rope 204, a connecting rope 205, a rope adjustment mechanism 3 for changing the state of the elastic rope 204, and a power transmission mechanism 4 for providing power to the rotating rod 206.

[0022] Two supports 201 are respectively located on both sides inside the housing 1. Each support 201 is provided with a pair of opposing support rods 202. The sleeve rod 203 is rotatably connected to the axis of the support rod 202. Each sleeve rod 203 is fitted with an elastic rope 204. One end of the elastic rope 204 is fixed to the support 201. A connecting rope 205 is fitted between the two sleeve rods 203. A rotating rod 206 is rotatably located in the sleeve rod 203. A scraping rod 207 is fixed inside the rotating rod 206. The rope adjustment mechanism 3 and the transmission mechanism 4 are both installed in the housing 1.

[0023] like Figure 3 As shown, the rope adjustment mechanism 3 includes: a shaft 301, a first magnetic block 302, a second magnetic block 303, and a pair of third magnetic blocks 304.

[0024] The shaft 301 is mounted on the housing 1. The shaft 301 has a through hole for the connecting rope 205 to pass through. The connecting rope 205 passes through the hole. The shaft 301 is equipped with a first magnetic block 302 and a second magnetic block 303. A pair of third magnetic blocks 304 are mounted on the housing 1. When the first magnetic block 302 or the second magnetic block 303 is attracted by one of the third magnetic blocks 304, the other magnetic block is not restricted by the third magnetic block 304.

[0025] It should be noted that the elastic cord 204 is an elastic rope, such as a rubber band. The first magnetic block 302, the second magnetic block 303, and the third magnetic block 304 are all magnets, and their magnetic force must be able to overcome the tension exerted on the sleeve rod 203 by the two elastic cords 204 when they attract each other and maintain a stable state. In addition, the scraping stick 207 in this embodiment is a cotton swab, and the inside of the rotating rod 206 is provided with a rubber layer for fixing the scraping stick 207 after it is inserted into the rotating rod 206.

[0026] like Figure 4 , Figure 6 , Figure 7 As shown, the end of the rotating rod 206 is tapered, and two opposing sliding grooves 5 are provided on the housing 1. The transmission mechanism 4 includes: a fixed frame 401, a first pressure frame 402, a second pressure frame 403, a spring 404, a friction surface 405 provided on the first pressure frame 402 and the second pressure frame 403, and a pair of pressure rods 406.

[0027] Among them, the fixed frame 401 is slidably installed in the slide groove 5; The first pressure frame 402 and the second pressure frame 403 are disposed in the fixed frame 401 and are slidably connected to each other. The second pressure frame 403 is slidably connected to the inner wall of the fixed frame 401. A spring 404 is installed between the first pressure frame 402 and the second pressure frame 403. The first pressure frame 402 and the second pressure frame 403 each have two opposing friction surfaces 405. A pair of pressure rods 406 are respectively disposed on the first pressure frame 402 and the second pressure frame 403.

[0028] like Figure 5 and Figure 6 As shown, in this embodiment, the friction surface 405 refers to the surface that comes into contact with and generates friction with the tapered portion at the root of the rotating rod 206 during the operation of the equipment. The angles of the first pressure frame 402 and the second pressure frame 403 are designed to match the tapered angle at the root of the rotating rod 206 to ensure that the friction surface 405 can effectively fit together. In specific implementation, anti-slip rubber can be provided on the friction surface 405 to further enhance the friction.

[0029] like Figure 6 As shown, the friction surface 405 of the first pressure frame 402 is disposed on its inner side, while the friction surface 405 of the second pressure frame 403 is disposed on its side facing the friction surface 405 of the first pressure frame 402, so that it can cooperate with the first pressure frame 402.

[0030] like Figure 6 and Figure 7 As shown, the fixed frame 401 has sliding plates 6 at both ends that are slidably connected to the housing 1, which are used to provide stable support during sliding and ensure that the fixed frame 401 remains stable when moving.

[0031] Each sliding plate 6 is fixedly mounted with a push plate 7, and a friction rubber pad 8 is provided between the push plate 7 and the housing 1. This structure can generate frictional resistance after the push plate 7 is pushed to a predetermined position, thereby limiting the sliding plate 6 and keeping it in a relatively fixed position.

[0032] In this embodiment, the housing 1 has an opening 9, and a cover 10 is installed at the opening 9 to facilitate the movement of the sleeve rod 203.

[0033] like Figure 8 As shown, the cover 10 includes: a cover body 1001, two through holes 1002, a movable membrane 1003, and a retaining ring 1004.

[0034] The cover 1001 is located at the opening 9. The cover 1001 has two through holes 1002. The through holes 1002 are provided with a flexible movable membrane 1003. The fixing ring 1004 is fixed at the center of the movable membrane 1003. The inside of the fixing ring 1004 is fixedly connected to the sleeve rod 203.

[0035] This structure ensures that the sleeve rod 203 can be flexibly adjusted, while effectively isolating the inside and outside of the housing 1, preventing pollutants or impurities from entering the inside of the housing 1.

[0036] In this embodiment, the active film 1003 is preferably made of natural latex.

[0037] Combination Figure 5 The working principle of this invention is as follows: During the testing process, the operator first installs the two scraping rods 207 onto the two rotating rods 206 respectively. Then, holding the long handle of the housing 1, while keeping the two rotating rods 206 parallel, the operator inserts the scraping rods 207 into the oral cavity, aligning them with the buccal mucosa on both sides.

[0038] Next, the operator presses down on the shaft 301, causing the first magnetic block 302 and the third magnetic block 304 to attract and fix each other. At this time, the connecting rope 205 is pulled down, thereby driving the scraping rod 207 to adhere to the surface of the buccal mucosa on both sides, while the conical ends of the two rotating rods 206 move closer to each other.

[0039] In this state, the operator pushes the push plate 7 forward with their thumb, causing the conical ends of the two rotating rods 206 to enter the gaps between the friction surfaces 405 of the first pressure frame 402 and the second pressure frame 403, respectively. As the push plate 7 advances further, the friction surfaces 405 and the conical ends of the rotating rods 206 fit tightly together, while the friction force generated between the bottom of the push plate 7 and the friction rubber pad 8 limits the position of the fixed frame 401, preventing it from shifting.

[0040] Subsequently, the operator presses the pressure rods 406 on the first pressure frame 402 and the second pressure frame 403 with their index finger knuckle and thumb, respectively, causing the friction surfaces 405 to move towards each other, driving the rotating rod 206 to rotate, thereby realizing the rotation of the scraping rod 207. When the pressure rods 406 are released, the spring 404 will push the first pressure frame 402 and the second pressure frame 403 to return to their original positions in the opposite direction. During the operation, the operator can press the pressure rods 406 repeatedly to make the rotating rod 206 rotate repeatedly, and the scraping rod 207 will continue to rotate.

[0041] Simultaneously, the operator must move the housing 1 up and down, causing the scraping rod 207 to rotate while scraping, thus achieving efficient sampling of the buccal mucosa on both sides. This process can significantly improve the uniformity and efficiency of cell collection and effectively reduce operator fatigue.

[0042] After the predetermined number of scrapings is reached, the operator pushes the push plate 7 backward and pushes the shaft 301 upward, causing the second magnetic block 303 and the third magnetic block 304 to attract and fix each other. Under the action of the elastic rope 204, the two scraping rods 207 return to a parallel state. At this time, the operator can remove the scraping rods 207 from the mouth and keep them for subsequent testing. Subsequently, a new scraping rod 207 can be inserted into the rotating rod 206, and the above operation can be repeated for the next sampling.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
