[0027] Combined with appendix Figures 1-6 The image shows a disposable dermatological fungal microscopy sampling file, which includes a handle 10 and a blade 13 fixed to the handle 10. The blade 13 has a scraping part and a filing part 30.

[0028] Temporary storage strip 19, which is installed on the blade 13;

[0029] Protective shell 12, which is rotatably mounted on the tool holder 10;

[0030] A locking component is provided to restrict the rotation of the protective shell 12.

[0031] Specifically, the handle 10 and the blade 13 are connected in a firm manner, such as by injection molding or by bonding with high-strength medical adhesive, to ensure that there will be no loosening or breakage during use. The connection should be smooth and natural, avoiding sharp edges to prevent scratching the user. Physical performance tests should also be conducted on the handle 10 and the blade 13, including a test on the firmness of the connection between the handle and the file. A tensile testing machine is used to apply a certain tensile force to the connection to observe whether there is any loosening or breakage, ensuring that the connection between the blade 13 and the handle 10 is firm.

[0032] The handle 10 can be made of a bright and easily distinguishable color, such as light blue or light green, for quick identification in a medical environment.

[0033] The protective shell 12 is rotatably mounted on the handle 10. The protective shell 12 can protect the blade 13 and prevent medical personnel from being accidentally injured by the blade 13 when handling the file. The locking component can lock the protective shell 12. When needed, the locking component can be opened and the protective shell 12 can be rotated to expose the blade 13. When not in use, the protective shell 12 can be flipped over to cover the blade 13.

[0034] The blade 13 can be used for both filing and scraping, and its one-piece design saves materials.

[0035] In one embodiment, a temporary storage groove 18 is provided on the blade 13, an insert shaft 24 is provided on the side wall of the temporary storage groove 18, a thin shaft 21 is fixed on the temporary storage strip 19, the thin shaft 21 is rotatably installed in the insert shaft 24, and the temporary storage strip 19 is installed in the temporary storage groove 18.

[0036] Specifically, the temporary storage tank 18 has a certain depth and is used to collect skin surface material samples (skin tissue and fungi, etc.). The scraped skin surface material samples can be temporarily stored in the temporary storage tank 18 for easy transfer to test slides or test tubes. The temporary storage strip 19 can be rotatably set in the temporary storage tank 18, and the scraped skin surface material samples can be stored in the temporary storage tank 18. When the skin surface material sample is to be taken out, the temporary storage tank 18 is pulled out, and the temporary storage tank 18 takes out the skin surface material sample, which is convenient for medical staff to take out the skin surface material sample.

[0037] In one embodiment, an iron sheet 20 is fixed on the temporary storage strip 19, and a magnetic pad 23 is fixed on the bottom surface of one end of the temporary storage groove 18. The magnetic pad 23 can attract the iron sheet 20.

[0038] Specifically, the magnetic pad 23 is magnetic, and the iron sheet 20 on the temporary storage strip 19 is made of iron material that can be attracted by a magnet, so that the temporary storage strip 19 can be fixed in the temporary storage groove 18.

[0039] In one embodiment, a lifting block 22 is fixed on the temporary storage strip 19.

[0040] Specifically, when it is necessary to retrieve a skin surface substance sample from the temporary storage tank 18, medical staff only need to use tweezers to hold the lifting block 22 and pull up the temporary storage strip 19 to retrieve the skin surface substance sample.

[0041] In one embodiment, the difference between this embodiment and the previous embodiment is that iron plates 20 are fixed at both ends of the temporary storage strip 19, and two magnetic pads 23 are fixed on the bottom surface of the temporary storage groove 18. The two magnetic pads 23 can attract the temporary storage strip 19, and the entire temporary storage strip 19 can be removed when it is used.

[0042] In one embodiment, the temporary storage strip 19 is arc-shaped, so that when the temporary storage strip 19 is removed, the skin surface substance sample will not slide out from both sides of the temporary storage strip 19.

[0043] In one embodiment, the file portion 30 is provided on one side of the blade 13, and the scraper portion is the sharp side of the blade 13.

[0044] Specifically, the blade 13 is long and thin, tapering towards the tip, making it easy to sample from deep within skin folds, nail edges, and other areas. When a file is needed to break down the surface material of the skin, the file 30 is used for filing. After the surface material of the skin is broken down, the scraper is used to scrape it off. The scraped surface material is stored in the temporary storage tank 18.

[0045] The surface of the file head 30 is designed with a specific texture, with a moderate depth, which can effectively scrape away skin surface cells and fungi without causing excessive damage to the skin. For example, a cross-grid pattern or a fine serrated pattern can be used.

[0046] Although the file is disposable, the blade 13 can be made of stainless steel, such as 304 or 316 stainless steel. Stainless steel has high hardness and wear resistance, making it easy to scrape skin samples, while also having good corrosion resistance.

[0047] Furthermore, the sharpness of the blade 13 needs to be tested. Using a rubber sheet or medical silicone block that simulates skin, a scratch test is conducted under specified pressure and angle to observe the scratching effect and the degree of damage to the test material, ensuring that sampling can be carried out effectively without excessively damaging the skin.

[0048] In one embodiment, the blade 13 is provided with scale lines 17.

[0049] Specifically, the precision of graduation line 17 is in millimeters, facilitating medical personnel to control the sampling depth, such as insertion sampling in skin folds, ensuring that the sample volume obtained meets the requirements for fungal microscopy. The graduation marks can be made by laser etching or printing to ensure clarity.

[0050] Verify the accuracy of the file's graduations by using a precision measuring instrument to measure the deviation between the actual sampling depth and the depth indicated by the graduations. The deviation should be controlled within ±0.2 mm.

[0051] In one embodiment, the locking assembly includes a fixed shaft 16 fixed to the handle 10, a resilient pin 14 fixed to the fixed shaft 16, and a rotating plate 15 slidably mounted on the resilient pin 14. The rotating plate 15 can be inserted into the protective shell 12 to restrict the rotation of the protective shell 12.

[0052] Specifically, the protective shell 12 protects the blade 13, preventing it from being exposed and causing injury during disposal. The locking mechanism is simple to operate and easy to open and close.

[0053] In one embodiment, anti-slip parts 11 are fixed on both sides of the handle 10.

[0054] Specifically, the anti-slip part 11 adopts an ergonomic design, with a shape suitable for medical personnel to hold, and has appropriate anti-slip texture or rubber coating to increase friction and prevent slippage during operation. The handle 10 is made of medical-grade plastic material, such as polypropylene (PP) or polyethylene (PE), which has good chemical stability, is non-toxic, odorless, wear-resistant, and easy to process and mold. This material also has a certain degree of flexibility, which can reduce hand fatigue to some extent.

[0055] The following are the instructions for using a disposable dermatological fungal microscopy sampling file;

[0056] Medical staff pull up the rotating plate 15 so that it is no longer inserted into the protective shell 12. They rotate the protective shell 12, which folds together with the handle 10, exposing the file part 30. The medical staff holds the handle 10 and aligns the file part 30 with the patient's area to file and grind, breaking down the skin material. Then, they use the scraping part of the blade 13 to scrape the sample. During scraping, the skin surface sample enters the temporary storage strip 19 in the temporary storage tank 18 and is then transferred to the microscopic examination area. The sample is removed by taking off the temporary storage strip 19 for microscopic examination.

[0057] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand and implement the content of this utility model. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
