Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of skin inspection, in particular to a scraper for thin-layer sampling of skin fungi. Background Art
[0002] A dermatophyte scraper is a medical tool used to collect samples from the skin surface for fungal testing. It is usually a small, handheld instrument with a blade or head for scraping samples. When using a dermatophyte scraper, medical staff will first clean the skin surface and then gently scrape the scraper to the area on the patient's skin that may be infected with fungi. Usually, this area will be selected where there are suspicious lesions or symptoms on the skin surface, such as redness, scaling or itching. The scraped sample is usually very small, only a few millimeters in size. After sampling, the medical staff places the sample in an appropriate container or slide and then sends it to the laboratory for fungal testing. This sampling method is often used to diagnose fungal infections such as Candida albicans infection, cutaneous Candida infection, etc. By detecting fungi in skin samples, doctors can determine whether there is a fungal infection and formulate a corresponding treatment plan. When using a dermatophyte scraper, medical staff need to follow strict hygiene standards to ensure the safety and accuracy of the sampling process while avoiding cross infection.
[0003] Since the blade is in direct contact with the human body when scraping human skin tissue, the blade needs to be cleaned and disinfected after sampling. The existing skin fungus thin layer sampling scraper is generally one-piece, and the blade cannot be disassembled, which is inconvenient to clean and disinfect the blade. Therefore, we proposed a skin fungus thin layer sampling scraper to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0028] Reference Figure 1-Figure 4 The utility model provides a technical solution: a skin fungus thin layer sampling scraper, comprising a handle body 1 and a blade 4, a disassembly mechanism 2 is arranged between the handle body 1 and the blade 4, the disassembly mechanism 2 comprises a mounting groove 201, a first wedge block 202, a limiting groove 203, a fixing block 204 and a second wedge block 205, the mounting groove 201 is arranged at one end of the handle body 1; the first wedge block 202 is fixedly connected to the blade 4, and the first wedge block 202 is plugged into the inner wall of the mounting groove 201; the limiting groove 203 is arranged on the outer wall of the first wedge block 202; the fixing block 204 is fixedly connected to the outer wall of the handle body 1; the second wedge block 205 and the fixing block 204 are all slidably connected to the handle body 1, the second wedge block 205 is plugged into the inner wall of the limiting groove 203, and a sliding groove 206 is arranged between the handle body 1 and the fixing block 204.
[0029] The second wedge block 205 is slidably connected to the inner wall of the slide groove 206, and the outer wall of the second wedge block 205 is fixedly connected with a connecting rod 208, and the connecting rod 208 is slidably connected to the fixed block 204. The other end of the connecting rod 208 is fixedly connected with a handle 209. By pulling the handle 209 outward, the handle 209 drives the second wedge block 205 to slide into the slide groove 206 through the connecting rod 208 until the second wedge block 205 is pulled out of the limiting groove 203, and the blade 4 can be pulled to pull the first wedge block 202 out of the mounting groove 201, so as to facilitate the disassembly of the blade 4 for disassembly and disinfection.
[0030] In a preferred embodiment, a spring 207 is fixedly connected between the second wedge block 205 and the inner wall of the slide groove 206, and the inclined surface of the second wedge block 205 is slidably connected to the inclined surface of the first wedge block 202. During installation, the first wedge block 202 is inserted into the installation groove 201, and the inclined surface of the first wedge block 202 contacts the inclined surface of the second wedge block 205, thereby pushing the second wedge block 205 into the slide groove 206. The second wedge block 205 compresses the spring 207 until the first wedge block 202 is completely inserted into the installation groove 201, and the spring 207 is reset, so that the second wedge block 205 returns to the initial position and is inserted into the limit groove 203 to complete the installation.
[0031] In a preferred embodiment, the handle body 1 includes a first handle 101 and a second handle 102, and an angle adjustment mechanism 3 is arranged between the first handle 101 and the second handle 102. The angle adjustment mechanism 3 includes a universal ball 301, a connecting rod 302 and a positioning bolt 303. The universal ball 301 is rotatably connected to the second handle 102, the positioning bolt 303 is threadedly connected to the second handle 102, and the connecting rod 302 is fixedly connected between the universal ball 301 and the first handle 101. By loosening the positioning bolt 303 and then holding the first handle 101, the universal ball 301 is rotated through the connecting rod 302, and the angle of the blade 4 can be adjusted. After the adjustment is completed, the positioning bolt 303 is tightened to facilitate the adjustment of the angle of the blade 4 as needed.
[0032] In a preferred embodiment, the outer wall of the second handle 102 is sleeved with an anti-slip cover 5, which is used to increase the friction between the palm and the second handle 102, so that the second handle 102 is not easy to slide from the palm.
[0033] Specifically, the working process or working principle of the skin fungus thin layer sampling scraper is as follows: the staff holds the anti-slip cover 5 on the second handle 102 and uses the blade 4 to scrape the fungal thin layer on the patient's skin, and then collects the fungal thin layer. During this process, the positioning bolt 303 can be loosened, and then the first handle 101 is held, and the universal ball 301 is rotated through the connecting rod 302 to adjust the angle of the blade 4. After the adjustment is completed, the positioning bolt 303 is tightened to facilitate the adjustment of the angle of the blade 4 as needed.
[0034] After sampling is completed, when the blade 4 needs to be cleaned, the handle 209 is pulled outward, and the handle 209 drives the second wedge block 205 to slide into the slide groove 206 through the connecting rod 208 until the second wedge block 205 is pulled out of the limiting groove 203, and the blade 4 can be pulled to pull the first wedge block 202 out of the installation groove 201, which is convenient for disassembling the blade 4 for disassembly and disinfection. During installation, the first wedge block 202 is inserted into the installation groove 201, and the inclined surface of the first wedge block 202 contacts the inclined surface of the second wedge block 205, thereby pushing the second wedge block 205 into the slide groove 206. The second wedge block 205 compresses the spring 207 until the first wedge block 202 is completely inserted into the installation groove 201, and the spring 207 is reset, so that the second wedge block 205 returns to the initial position and is inserted into the limiting groove 203 to complete the installation.
