Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a gold microneedle needle structure. Background Art

[0002] Microneedle therapy, also known as microneedling, is a medical technology that uses tiny needle-like instruments to implement mechanical or physical, minimally invasive stimulation on the skin soft tissue in order to achieve therapeutic or cosmetic effects. It can be accompanied by the simultaneous or step-by-step administration of drugs or effective ingredients, with the help of microneedles to improve their transdermal / absorption efficiency, thereby enhancing the therapeutic or cosmetic effects.

[0003] Microneedle needles are key instruments for microneedle therapy and are disposable consumables. During cosmetic treatments, the microneedles need to be fixed on the skin to prevent them from shaking. Currently, all microneedles on the market are fixed by negative pressure adsorption. However, due to the need to facilitate the connection of a negative pressure source, currently available needles are provided with a negative pressure tube on the outer wall that is connected to the negative pressure cavity on the needle (such as the technical solution of application number CN202223329213.8). However, in actual use, operators have found that the external negative pressure tube and the trachea thereon will hinder the treatment operation, which will hinder the rotation of the handle and block the operator's line of sight. Therefore, based on this problem, it is necessary to improve the existing microneedles. Utility Model Content

Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0024] The gold microneedle needle structure of the preferred embodiment of the utility model is as follows Figure 1-2As shown, the needle head includes a shell 10, and a microneedle module 20 arranged inside the shell 10. It should be explained that the microneedle module 20 is a conventional accessory in this field and is a well-known technology, which will not be described in detail herein. Furthermore, a needle exit area 11 is provided on the top outer surface of the shell corresponding to the needle head 21 of the microneedle module 20, and a negative pressure groove 30 is also provided around the needle exit area 11. A needle hole 40 for the needle head 21 of the microneedle module to enter and exit is provided on the needle exit area 11. A channel 50 connected to the inner cavity of the shell is provided on the inner wall of the negative pressure groove 30, and a pipe fitting 60 connected to the channel 50 is provided inside the shell 10. The overall structure of the utility model is simple, and the structural layout is compact and reasonable. The pipe fitting 60 can not only realize the internal connection of the trachea of ​​the treatment device, but also make the outer surface of the shell 10 more neat and beautiful, and will not block the line of sight or hinder the operation during the use of the operator.

[0025] In this embodiment, the entrance of the channel 50 is located at the lower end of the inner wall of the negative pressure groove 30 away from the needle hole 40, so as to facilitate the setting position of the outlet of the channel 50 away from the microneedle module 20 to avoid position conflict between the tube 60 and the microneedle module 20 during installation.

[0026] In this embodiment, a first positioning groove 70 is provided on the inner wall of the shell corresponding to the upper end of the tube 60, and a first annular seal 80 is provided in the first positioning groove 70 corresponding to the tube 60 to prevent air leakage, so as to ensure the airtightness between the upper end of the tube 60 and the channel 50, so as to avoid air leakage at the connection of the tube 60 after connecting the treatment device, thereby causing the needle to fall off the skin.

[0027] In this embodiment, the needle also includes a filter 90 that is arranged corresponding to the tube 60 and is used for filtering skin debris and drug droplets on the skin surface to prevent the debris and droplets from entering the treatment device.

[0028] In this embodiment, the filter element 90 is disposed below the pipe element 60 to intercept debris and liquid droplets and temporarily store them inside the pipe element 60 .

[0029] In this embodiment, the shell 10 includes an upper half shell 101 and a lower half shell 102 detachably connected thereto, and the pipe fitting 60 is arranged between the upper half shell 101 and the lower half shell 102. When assembled in place, the lower half shell 102 presses the pipe fitting 60 against the upper half shell 101 to ensure the stability of the pipe fitting 60. At the same time, it is also convenient to disassemble and replace the pipe fitting 60, reduce the fixed connection structure, and reduce the cost.

[0030] In this embodiment, an abutment position is provided at the lower end of the corresponding tube fitting 60 on the lower half shell 102, and an airway 100 is provided on the abutment position corresponding to the tube fitting 60. The airway 100 runs through the lower half shell 102, and an air nozzle 110 is provided at the bottom of the lower half shell 102 corresponding to the airway 100 to facilitate connection to the airway on the handle of the treatment device.

[0031] In this embodiment, a second positioning groove 120 is provided at the lower end of the corresponding pipe fitting 60 at the abutting position, and a second annular seal 130 is provided in the second positioning groove 120 corresponding to the pipe fitting 60 to prevent air leakage, so as to ensure the sealing of the connection of the pipe fitting 60 and prevent air leakage during use.

[0032] In this embodiment, a countersunk hole 130 coaxial with the airway 100 is provided on the bottom surface of the second positioning groove 120, and the filter element 90 is arranged in the countersunk hole 130 to prevent it from being squeezed by the pipe fitting 60. At the same time, the inner cavity of the pipe fitting 60 can be fully utilized to temporarily intercept debris and droplets inside the pipe fitting 60, so as to facilitate the discharge of debris and droplets when replacing the pipe fitting 60.

[0033] In this embodiment, the lower end of the pipe 60 is interference fit with the second positioning groove 120, so that the pipe 60 can still stand upright on the lower half shell 102 after the upper half shell 101 is disassembled, thereby preventing the pipe 60 from tipping over and causing debris to be scattered to other locations.

[0034] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
