Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a skin scraper. Background Technology

[0002] In related technologies, skin scraping is a method for collecting shed keratinocytes from the surface of human or animal skin. It typically uses a device called a skin scraper to collect samples. This device contains a sharp scraper or a brush-like head that can easily collect cells from the skin surface and transport them to a laboratory for analysis. Skin scraping is very common and is used in research on skin diseases, drug effects, genetic studies, and more.

[0003] However, during the actual research and development process, the inventors discovered that existing skin flake sampling techniques all use metal scrapers, which are very sharp. During sampling, if an error occurs, the scraper can easily cut the skin of the person being sampled, making it very inconvenient and unsafe to use. In addition, the scraper is not disposable. When it is used for different people, the blade needs to be sterilized at high temperature by burning it with an alcohol lamp. After high temperature sterilization, the blade needs to be further sterilized by soaking it in alcohol. This seriously affects the efficiency of skin flake sampling and also poses a risk of incomplete sterilization.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a dandruff scraper, which effectively solves the technical defects of the scraper used for dandruff sampling in the prior art, such as inconvenience in use, unsafe use, and incomplete disinfection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dander scraper, comprising a handle and a scraping part, wherein the handle and the scraping part are integrally formed by injection molding of plastic material; the upper and / or lower sides of the scraping part are provided with a blade, and the end of the blade has a rounded portion.

[0007] The beneficial effect of the dandruff scraper provided in this application is that, compared with the prior art;

[0008] Firstly, by injection molding the handle and scraping part into one piece from plastic material, the cost is low and it can be destroyed after one skin flake sampling, achieving the function of single use and saving the tedious work of disinfecting the scraper; it can not only improve the efficiency of skin flake sampling, but also prevent the risk of infection due to incomplete disinfection and poor shaping.

[0009] Secondly, the scraping part is made of plastic material, and the blade of the scraping part has a rounded end. When sampling skin flakes, the blade can only scrape away the skin flakes on the surface of the person being sampled, and the rounded end can prevent the blade from cutting the skin of the person being sampled, thereby improving the convenience and safety of skin flake sampling.

[0010] As a preferred embodiment, the handle and scraping part are made of polycarbonate or acrylonitrile-butadiene-styrene copolymer or polyvinyl chloride or polypropylene.

[0011] As a preferred embodiment, the scraping part is integrally formed on the front end of the handle part, and the blade part includes an upper blade part located at the upper end of the scraping part and a lower blade part located at the lower end of the scraping part.

[0012] As a preferred embodiment, the upper end of the upper blade portion is provided with an inwardly concave arc shape, so that the upper blade portion forms a concave arc-shaped blade portion;

[0013] The bottom of the lower blade has an outward convex arc, making the lower blade a convex arc-shaped blade.

[0014] Compared with existing technologies, the design of concave and convex arc-shaped blades allows for the use of different blade shapes to adhere to the skin during dandruff sampling, thereby further improving the reliability and convenience of dandruff sampling.

[0015] As a preferred option, the curvature of the concave arc-shaped cutting edge is smaller than that of the convex arc-shaped cutting edge.

[0016] As a preferred embodiment, the rounded portion includes a first rounded portion located at the upper end of the upper blade portion and a second rounded portion located at the lower end of the lower blade portion, wherein the first rounded portion and the second rounded portion have the same diameter.

[0017] As a preferred embodiment, the front ends of the upper and lower cutting edges are connected, while the rear ends of the upper and lower cutting edges are not connected, and a spherical portion is provided at the junction of the front ends of the upper and lower cutting edges.

[0018] Compared with existing technologies, by providing a spherical part at the junction of the upper and lower blades, this scraper can extend into the gaps of the nail to allow the upper and lower blades to scrape away skin flakes from inside the nail, while preventing skin puncture. Therefore, the scraper can achieve multiple methods of skin flake sampling, further improving the reliability and convenience of skin flake sampling.

[0019] As a preferred embodiment, a break line, a break groove, or an intermittent break hole is provided between the handle and the scraping part.

[0020] Compared with existing technologies, by setting a break line, break groove, or intermittent break hole, the handle and scraping part of the scraper can be broken after the scraper has completed one dander sampling. On the one hand, this can indicate that the scraper has been used and cannot be used again. On the other hand, it can facilitate subsequent dander detection by only detecting the dander attached to the scraping part.

[0021] As a preferred embodiment, the center position of the handle in the vertical direction is taken as the first center point, and the height of the handle in the vertical direction gradually decreases from front to back towards the first center point.

[0022] As a preferred embodiment, the thickness of the handle and the scraping part is the same in the left and right directions. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] Please refer to the following: Figures 1 to 6 The dandruff scraper 100 provided in the embodiments of this application will now be described. The dandruff scraper 100 includes: a handle portion 10 and a scraping portion 20.

[0041] The handle 10 and the scraping part 20 are integrally injection molded from plastic material. The upper and / or lower sides of the scraping part 20 are provided with a blade, the end of which has a rounded portion. Specifically, compared with the prior art; firstly, by using a handle 10 and scraping part 20 integrally injection molded from plastic material, the cost is low, and it can be destroyed after one skin flake sampling, achieving a single-use function and eliminating the tedious work of disinfecting the scraper; this not only improves the efficiency of skin flake sampling but also prevents the risk of infection due to incomplete disinfection and poor shaping; secondly, the scraping part 20, made of plastic material, has a rounded end to its blade; when sampling skin flakes, the blade can only scrape away skin flakes from the surface of the sampled person's skin, and the rounded portion can prevent the blade from cutting the skin of the sampled person, thereby improving the convenience and safety of skin flake sampling.

[0042] In some embodiments, the handle portion 10 and the scraping portion 20 are made of any one of the following plastic materials: polycarbonate, acrylonitrile-butadiene-styrene copolymer, polyvinyl chloride, or polypropylene. The process of producing the shaving scraper 100 is as follows: an injection mold is provided, the plastic material is melted into a hot melt slurry and injected into the cavity of the injection mold; the cavity of the injection mold is cooled and the mold is opened to form the shaving scraper 100. After polishing and grinding, the shaving scraper 100 can be packaged to complete the production of one shaving scraper 100.

[0043] Specifically, the shaving scraper 100, which is injection molded from plastic material, has lower manufacturing costs and is less difficult to manufacture than the scraper structure made of metal in traditional technology, making it particularly suitable for mass production operations; even the disposable shaving scraper 100 has a much lower usage cost than the scraper structure made of metal.

[0044] In other embodiments, the scraping part 20 is integrally formed on the front end of the handle part 10, and the blade part includes an upper blade part located at the upper end of the scraping part 20 and a lower blade part located at the lower end of the scraping part 20. During the skin flake sampling process, different sides of the blade part can be selected for skin flake sampling according to actual needs.

[0045] Preferably, the upper end of the upper blade portion has an inwardly concave arc shape, forming a concave arc-shaped blade portion 21; the bottom of the lower blade portion has an outwardly convex arc shape, forming a convex arc-shaped blade portion 22. The curvature of the concave arc-shaped blade portion 21 is smaller than that of the convex arc-shaped blade portion 22. By providing the concave arc-shaped blade portion 21 and the convex arc-shaped blade portion 22, blade portions of different shapes can be adapted to different areas of skin shape on the sampled person, improving the reliability and convenience of skin flake sampling.

[0046] Furthermore, the rounded portion includes a first rounded portion 23 located at the upper end of the upper cutting edge and a second rounded portion 24 located at the lower end of the lower cutting edge, wherein the first rounded portion 23 and the second rounded portion 24 have the same diameter. The front ends of the upper and lower cutting edges are connected, while the rear ends of the upper and lower cutting edges are not connected. A spherical portion 25 is provided at the junction of the front ends of the upper and lower cutting edges.

[0047] Specifically, a spherical portion 25 is provided at the junction of the upper and lower blades. This spherical portion can extend into the gaps of the nail to allow the upper and lower blades to scrape the skin flakes inside the nail, while preventing skin puncture. Therefore, the skin scraper 100 can perform skin flake sampling in multiple ways, further improving the reliability and convenience of skin flake sampling.

[0048] Preferably, both the upper and lower blade portions include cutting angles 26 on the left and right sides, and the cutting angles 26 are asymmetrically inclined. The distance by which the cutting angles 26 are inclined in the first direction x1 is less than the distance by which they are inclined in the second direction y1, and the rounded portions are located at the intersection of the ends of each pair of cutting angles 26. With this structure, the problem of skin abrasion can be avoided when extracting skin flakes.

[0049] Understandably, the handle 10 has chamfered edges on both the upper and lower ends and the left and right sides to prevent skin scratches when holding the handle 10.

[0050] In some embodiments, the handle portion 10 has its center position in the vertical direction as the first center point, and the height of the handle portion 10 in the vertical direction gradually decreases towards the first center point from front to back. The handle portion 10 and the scraping portion 20 have the same thickness in the horizontal direction. A break line or break groove 11 or an intermittent break hole 12 is provided between the handle portion 10 and the scraping portion 20.

[0051] Specifically, by setting a break line, a break groove 11, or an intermittent break hole 12, the handle 10 and the scraping part 20 can be broken after the dandruff scraper 100 completes one dandruff sampling. On the one hand, this can indicate that the dandruff scraper 100 is in a used state and cannot be used again. On the other hand, it can facilitate subsequent dandruff detection by only detecting the dandruff attached to the scraping part 20.

[0052] Preferably, when the scraper 100 is provided with a break line, a break groove 11, or an intermittent break hole 12, the break line is set by stamping or directly formed during injection molding using the mold's movement. When the break groove 11 is provided, it can be located on the left and / or right sides of the scraper 100, extending upwards through the upper and lower surfaces of the scraper 100. When the intermittent break holes 12 are provided, they are evenly spaced along the vertical direction of the scraper 100, extending through both sides of the scraper 100; simultaneously, the uppermost break hole needs to extend through the upper surface of the scraper 100, and the lowermost break hole needs to extend through the lower surface of the scraper 100, making it easier to break the handle 10 and the scraping part 20.

[0053] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
