Description

Technical Field

[0001] The present invention relates to the technical field of medical cosmetic equipment, and in particular to a microneedle operation device. Background Art

[0002] Skin aging is related to the collagen content in the dermis of the epidermis. When the collagen content in the dermis decreases, it will cause dry skin and wrinkles. In order to delay skin aging and improve skin wrinkles, it is necessary to continuously supplement collagen or inject new collagen into the skin. At present, collagen is mostly supplemented by applying or spraying nutrient solutions containing vitamin C, peptides, etc. that help collagen production on the surface of the skin. Through the rolling of the microneedle operation device, the nutrient solution enters the skin along with the microneedles. However, most of the nutrients in the nutrient solution cannot enter the dermis on the surface of the skin, and most of the nutrient solution remains in the epidermis, resulting in unsatisfactory actual effects.

[0004] However, the device needs to output the drug solution through an external fluid driving mechanism, and the roller-type microneedles are connected to each other through an external delivery pipe. When the user uses it, the external delivery pipe may hinder the user's operation, making it inconvenient for the user to use. Summary of the invention

[0005] The first object of the present invention is to provide a microneedle manipulation device with a simple structure and convenient user operation.

[0007] It can be seen from the above scheme that the microneedle operation device of the utility model is provided with a first flow channel and a second flow channel through a first wheel frame. The medicine flows out from the first liquid outlet of the liquid storage pipe, passes through the first flow channel, the second flow channel, and the fourth flow channel, reaches the inside of the hollow microneedle, and flows out from the inside of the hollow microneedle. When the user is in use, through the setting of the flow channel, the medicine can flow from the liquid storage pipe through the wheel frame to the hollow shaft, so that the medicine can flow out of the hollow microneedle. As the roller rolls, the microneedle penetrates into the dermis, and the medicine enters the dermis along with the microneedle. Since the medicine is stored in the liquid storage pipe inside the operating handle, the microneedle operation device of the utility model does not need to be provided with an external fluid driving mechanism, so that the structure of the device is simple and convenient for users to use.

[0033] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0034] See also Figure 1 and Figure 2 The microneedle operation device 1 of the utility model includes an operating handle 3, a wheel frame 2 and a roller 1. The operating handle 3 includes an inner cavity 33. A liquid storage pipe 331 is arranged at the front end of the inner cavity. The liquid storage pipe 331 stores liquid medicine inside.

The inner cylinder 341 is sleeved on the liquid storage pipe 331, and the inner cylinder 341 moves above the liquid storage pipe 331. The spring 351 is sleeved outside the inner cylinder 341. The spring 351 can push the inner cylinder to move toward the direction of the operating handle 3 close to the liquid storage pipe under the action of elastic force.

[0036] The inner cavity of the operating handle 3 also includes a rotating ring 342, a rotating rod 344, a piston 343 and a limiting plate 345; the first end of the liquid storage pipe 331 is provided with a first liquid outlet 333, the second end of the liquid storage pipe 331 is provided with a rotating ring mounting position 346, and the rotating ring 342 is arranged in the rotating ring mounting position 346; the piston 343 is arranged inside the liquid storage pipe 331, and the first end of the rotating rod 344 is rotatably connected to the piston 343; the rotating rod 344 passes through the rotating ring 342, the second end of the rotating rod 344 is fixedly connected to the inner cylinder 341, and the rotating rod 344 is threadedly connected to the rotating ring 342; the limiting plate 345 is arranged above the rotating wheel 342, and the limiting plate 345 is clamped on the rotating ring mounting position 346 of the liquid storage pipe 331.

[0037] The operating handle 3 further includes a speed regulating rod 361, which penetrates the inner cavity 33 from the end of the handle body 31 in the first axial direction, passes through the inner cylinder 341, and then abuts against the limit plate 345. The speed regulating rod 361 is threadedly connected to the handle body 31. The speed regulating rod 361 can adjust the rotation speed of the rotating ring 342 by adjusting the pressure between the limit ring 3411 and the rotating ring 342, thereby controlling the speed at which the piston 343 moves toward the direction of the liquid storage pipe 331 in the operating handle, so as to adjust the movement speed of the liquid medicine.

[0038] By configuring the rotating ring 342, the rotating rod 344, the piston 343 and the limiting plate 345, the inner cylinder 341 can slowly push the piston 343 toward the liquid storage pipe 331 through the cooperation of the rotating rod 344 and the rotating ring 342 under the action of the spring 351, and due to the configuration of the rotating ring 342, the rotating ring 342 can move toward the liquid storage pipe 331 at a uniform speed and slowly, thereby achieving uniform supply of the medicine liquid and avoiding excessive supply of the medicine liquid per unit time, which would lead to loss and waste of nutrient solution.

[0039] The handle body 31 of the operating handle 3 is provided with a guide component 317, and the guide component 317 is provided with at least one guide groove 316 and a limit groove 314, the limit groove 314 extends along the circumference of the handle body 31, and the guide groove 316 extends along the axial direction of the operating handle 3, and the guide groove 316 and the limit groove 314 pass through the handle body 31; the guide groove 316 is connected to the limit groove 314.

A guide rod 321 is fixedly arranged outside the limit ring 3411, and the guide rod 321 passes through the guide component 317 and protrudes from the handle of the operating handle 3. Since the inner cylinder 341 moves forward under the action of the spring 351, the guide rod 321 moves forward with the inner cylinder 341, and the guide rod 321 is arranged in the guide component 317, so the guide component can limit the inner cylinder from moving forward.

[0041] Furthermore, the number of the guide components 317 can be set to two, and the guide components 317 are centrally symmetrically arranged; correspondingly, the number of the guide rods 321 is two, and one guide rod 321 corresponds to one guide component 317 .
