Description

Technical Field

[0001] This utility model relates to the field of medical microneedle roller technology, and more specifically, to a skin microneedle roller. Background Technology

[0002] Microneedling roller therapy uses numerous tiny needles on a microneedling roller to stimulate the skin. In a very short time, the microneedles can create more than 200,000 microchannels, allowing active ingredients to effectively penetrate the skin. When combined with special products for wrinkle reduction, whitening, repair, and scar removal, it can achieve ideal results such as reducing wrinkles, treating scars and stretch marks, whitening the skin, reducing pigmentation, improving eye wrinkles and dark circles, and tightening and lifting facial skin tissue. Its effects are comparable to laser and filler-based cosmetic surgery.

[0003] However, when using existing microneedle rollers, medical staff usually need to first puncture the skin surface to be treated with the roller, and then apply the necessary medication to the punctured skin surface with tools such as ointment brushes. In this process, the punctured skin will be exposed to the air for a long time, which poses a significant risk of infection, and the operation efficiency of medical staff is low. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing microneedle rollers require piercing the skin with the roller needle before applying medication, resulting in prolonged exposure of the pierced skin and a high risk of infection. This application provides a skin roller that, immediately after piercing the skin, uses components such as scrapers to evenly spread medication or ointment onto the skin surface. This significantly improves operational efficiency and reduces the risk of infection caused by prolonged exposure of the pierced skin to the air.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a skin roller, including a microneedle roller and a handle. The microneedle roller is mounted on the head end of the handle, and the roller surface of the microneedle roller is perpendicular to the handle. A drug delivery tube is inserted inside the handle, and the discharge end of the drug delivery tube extends from the end of the handle near the roller surface of the microneedle roller. A scraper is disposed at the end of the handle near the microneedle roller, and the scraper is located on one side of the roller surface of the microneedle roller.

[0007] Preferably, the microneedle roller is in the shape of an inverted cylinder, and a rotating shaft is inserted through the center of the microneedle roller. The rotating shaft is arranged in the same direction as the microneedle roller, and the two ends of the rotating shaft are detachably connected to the head end of the handle, so that the microneedle roller is rotatably connected to the handle.

[0008] Preferably, the discharge end of the drug delivery tube is provided with multiple discharge branch pipes, each discharge branch pipe is equipped with a discharge nozzle, the discharge nozzles are distributed on the end face of the rod handle near the microneedle roller, and the discharge nozzles are positioned directly opposite the arcuate side of the microneedle roller.

[0009] Preferably, a liquid storage chamber is embedded in the middle section of the rod handle, and the liquid storage chamber is connected to the discharge branch pipe.

[0010] Preferably, the liquid storage chamber is an elastic rubber tube, and the inner cavity of the liquid storage chamber can be pressurized.

[0011] Preferably, one side of the scraper is detachably connected to the handle, and the other opposite side of the scraper can extend to the side of the microneedle roller away from the handle.

[0012] Preferably, the scraper blade has bristles on the side away from the handle.

[0013] Preferably, the arcuate sidewall of the microneedle roller is provided with a plurality of needles.

[0014] The technical solution of this utility model has the following beneficial effects:

[0015] This invention relates to a skin roller needle, which can immediately spread medication or ointment evenly on the skin surface after the roller needle punctures the skin using components such as scrapers. This greatly improves operational efficiency and reduces the risk of infection caused by prolonged exposure of the skin to the air after puncture. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Where specific conditions are not specified in the embodiments, they are performed according to conventional conditions or conditions recommended by the manufacturer; where the manufacturers of instruments, equipment, reagents, or raw materials are not specified, they are all conventional products that can be purchased commercially. The following are specific embodiments in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, this embodiment provides a skin roller needle, including a microneedle roller 1 and a handle 2. The arc-shaped sidewall of the microneedle roller 1 is provided with a plurality of roller needles 12 for piercing the patient's skin surface. The microneedle roller 1 is mounted on the head end of the handle 2, and the roller surface of the microneedle roller 1 is perpendicular to the handle 2. A drug delivery tube 3 is inserted inside the handle 2, and the discharge end of the drug delivery tube 3 extends out from the end of the handle 2 near the roller surface of the microneedle roller 1. A scraper 4 is provided at the end of the handle 2 near the microneedle roller 1. The scraper 4 is located on one side of the roller surface of the microneedle roller 1. One side of the scraper 4 is screwed to the handle 2, and the other opposite side of the scraper 4 can extend to the side of the microneedle roller 1 away from the handle 2. The side of the scraper 4 away from the handle 2 is provided with bristles 41 for brushing out liquid medicine, ointment, etc.

[0023] In this embodiment, the microneedle roller 1 is an inverted cylinder. A rotating shaft 11 is inserted through the center of the microneedle roller 1. The rotating shaft 11 is arranged in the same direction as the microneedle roller 1. The two ends of the rotating shaft 11 are detachably connected to the head end of the handle 2, so that the microneedle roller 1 and the handle 2 are rotatably connected. The discharge end of the drug delivery tube 3 is provided with multiple discharge branch tubes 31. The discharge branch tubes 31 are equipped with discharge nozzles 32. The discharge nozzles 32 are distributed on the end face of the handle 2 near the microneedle roller 1, and the discharge nozzles 32 are arranged facing the arc side of the microneedle roller 1.

[0024] In this embodiment, a liquid storage chamber 21 is embedded in the middle section of the handle 2, and the liquid storage chamber 21 is connected to the discharge branch pipe 31. The liquid storage chamber 21 is an elastic medical silicone rubber tube, and the inner cavity of the liquid storage chamber 21 can be pressurized. When in use, the liquid is filled into the liquid storage chamber 21, and the liquid can be squeezed out from the discharge nozzle quickly and conveniently by squeezing the liquid storage chamber 21. This allows the liquid to be evenly spread on the skin surface immediately after the roller needle 12 punctures the skin through the action of components such as the scraper 4, which can greatly improve the operation efficiency and reduce the problem of infection caused by prolonged exposure of the skin to the air after puncture.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
