[0029] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] In order to solve the technical problem of how to avoid excessive cell damage during oral cell collection, the present utility model provides an oral cell collection device, which can directly contact the oral cavity with a collection paper to collect cells, avoiding excessive cell damage during collection.

[0031] Please refer to Figure 1 , Figure 1Schematic diagram of the structure of an oral cell collection device in an embodiment of the present utility model. The oral cell collection device includes a sampling rod 1 and a sampling paper 2. The sampling rod 1 includes a rod body 11, a clip 12, and a positioning clip 13. The positioning clip 13 is fixed at the end of the rod body 11. The two clips 12 are symmetrically arranged on both sides of the end of the rod body 11, forming an inverted triangle arrangement with the positioning clip 13. The sampling paper 2 is bendably inserted between the inner sides of the clip 12 and the positioning clip 13. Under the inverted triangle arrangement, the sampling paper 2 is bent to form a U-shaped sampling groove 201 at the positioning clip 13 and sampling convex edges 202 that turn outwards in an arc shape from both ends of the U shape at the clip 12. Supported by the bottom of the clip 12, the sampling convex edges 202 can scrape oral cells from the inner wall of the oral cavity, and the sampling groove 201 beside it can serve as a receiving space for the scraped oral cells to collect oral cells. The entire sampling paper 2 is in a U-shaped bent state and is slender, facilitating insertion into the oral cavity and the relatively narrow areas on both sides of the teeth, enabling collection of more sample cells, and directly adhering to the sampling paper 2 without secondary transfer, avoiding excessive damage to the collected cells during the transfer process.

[0032] It can be understood that the sampling paper 2 is inserted in the sampling rod 1 in an inserted installation manner, located at the end of sampling, and directly inserted into the oral cavity for cell collection. During collection, the clip 12 serves as the bottom support for the position where cells are scraped, enabling the flexible sampling paper 2 to have a rigid support part, having the function of scraping cells like a traditional swab. And the number of sampling convex edges 202 is two, and both sides can use a tilted position to scrape cells, mainly scraping cells by moving, so as to facilitate the scraping of cells into the sampling groove 201.

[0033] It should be noted that the sampling paper 2 is the collection card in oral cell collection. The collection card is designed in the form of a thin paper, which is usually called filter paper or cellulose paper. Such thin paper collection cards are very common in the field of biomedical science, especially in blood sample collection and DNA extraction, which are prior arts and will not be elaborated here.

[0034] In one of the embodiments, please refer to Figure 2 and Figure 3 , in order to insert the sampling paper 2 at the positioning clip 13, the positioning clip 13 includes an upper clip 131 and a lower clip 132. The upper clip 131 and the lower clip 132 are connected to the end of the rod body 11 in an up-and-down distribution and form a first gap 101 for inserting and clamping the sampling paper 2. The first gap 101 matches the thickness of the sampling paper 2, and the sampling paper 2 can be inserted into the first gap 101. The position of the first gap 101 mainly serves as the positioning of the bottom of the sampling groove 201, pulling the sampling paper 2 downwards to form the sampling groove 201.

[0035] Furthermore, in order to insert the sampling paper 2 at the clamp 12, the clamp 12 includes an extension rod 121, a first clamp rod 122 and a second clamp rod 123. One end of the extension rod 121 is connected to the rod body 11, and the extension rod 121 is inclined upward. The other end of the extension rod 121 is connected to the first clamp rod 122 and the second clamp rod 123, and a second gap 102 is formed between the first clamp rod 122 and the second clamp rod 123 for inserting and clamping the sampling paper 2. The second gap 102 matches the thickness of the sampling paper 2, and the sampling paper 2 can be inserted into the second gap 102. The second clamp rod 123 is in the shape of a cylindrical rod. At this time, the outer arc surface of the second clamp rod 123 fits with the sampling paper 2 to form a sampling convex edge 202 with an arc-shaped outer surface, so as to avoid damage to the oral cavity when scraping oral cells.

[0036] Furthermore, in order to prevent the positioning clip 13 from blocking too much area of ​​the sampling paper 2, the length of the positioning clip 13 is smaller than the length of the clamp 12, reducing the area covered by the sampling paper 2, and only needs to play a basic pulling and positioning role.

[0037] Furthermore, in order to prevent the second clamping rod 123 from interfering with the scraping action of the sampling protrusion 202 on the oral cells, the second clamping rod 123 is located below the side of the first clamping rod 122, and the diameter of the second clamping rod 123 is smaller than the diameter of the first clamping rod 122, so that the second clamping rod 123 is covered below the first clamping rod 122, thereby preventing the sampling protrusion 202 from interfering with the scraping action of the oral cells.

[0038] Furthermore, in order to quickly position the sampling paper 2 when inserting it and avoid the sampling paper 2 from slipping when scraping left and right, thick layers 203 are provided on both sides of the sampling paper 2, and the thickness of the thick layer 203 is greater than the width of the second gap 102, so that after insertion, the thick layer 203 forms a limit on the left and right ends, thereby avoiding the slipping of the sampling paper 2.

[0039] In one embodiment, see Figure 4 , Figure 5 and Figure 6 In order to facilitate the contactless removal and storage of the sampling paper 2, a splitting piece 3 is also included, and the splitting piece 3 includes a bottom plate 31 and a convex rod 32. A plurality of the convex rods 32 are arranged on the bottom plate 31, and are used to push the side of the sampling paper 2, wherein the convex rod 32 is inserted in the gap between the sampling paper 2 and the extension rod 121, and abuts against the side of the sampling paper 2. Then, the sampling rod 1 is pulled to separate the sampling rod 1 from the sampling paper 2, and the sampling paper 2 is retained on the bottom plate 31. Due to the loss of the limit of the clamp 12 and the positioning clamp 13, the sampling paper 2 automatically tends to be flattened.

[0040] Understandably, when splitting the sampling paper 2, the sampling groove 201 is oriented towards the bottom plate 31. At this time, it is easy to abut the convex rod 32 against the side of the sampling paper 2, thus facilitating the splitting action.

[0041] It should be noted that both the first gap 101 and the second gap 102 have openings away from the rod body 11. Therefore, when splitting, the convex rod 32 abuts against the side of the sampling paper 2 close to the rod body 11 and pushes the sampling paper 2 away towards the opening.

[0042] Furthermore, in order to cover and position the sampling paper 2 during storage, the splitting member 3 further includes a cover plate 33. The cover plate 33 is hinged to the bottom plate 31. After the sampling paper 2 is separated from the sampling rod member 1, closing the cover plate 33 can further flatten the sampling paper 2 and protect it during storage.

[0043] Furthermore, a buckle 301 is provided on the convex rod 32, and a slot 302 matching the buckle 301 is opened on the cover plate 33. When closing, the buckle 301 is engaged with the slot 302 to make the closing press more stable.

[0044] Furthermore, a sealing strip 303 is provided on the side of the cover plate 33 close to the bottom plate 31 to make the closing storage have a sealing effect.

[0045] For a better understanding of the present utility model, the following is a detailed description of the technical solution of the present utility model in conjunction with Figures 1 to 6 Insert the sampling paper 2 into the first gap 101 and the second gap 102 to form a U shape, and turn the two ends downward and inwardly to form a sampling groove 201 in the middle and sampling convex edges 202 at both ends. It is preferably in a flat and slender shape, which is convenient for inserting into the oral cavity for sampling. Among them, the sampling convex edge 202 is used to scrape off oral cells, and the sampling groove 201 is used to accommodate oral cells; after sampling, cooperate with the splitting member 3, abut the convex rod 32 against the side of the sampling paper 2, and pull the sampling rod member 1, so as to push the sampling paper 2 away from the sampling rod member 1 by abutting and spread it flat on the bottom plate 31. Finally, just close the cover plate 33. If it needs to be dried, wait for the sampling paper 2 to dry and then close the cover plate 33.

[0046] The above specific embodiments of the present utility model do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
