Description

Technical Field

[0001] This application relates to the field of physiotherapy equipment technology, specifically to a microneedle structure. Background Technology

[0002] In recent years, the permeation enhancement method has frequently appeared in the field of beauty and skincare. By using microneedles to puncture the skin, a large number of micropores are created in the stratum corneum and epidermis. After applying drugs or skincare products to the skin punctured by the microneedles, the skin's absorption efficiency of the drugs or skincare products can be improved, thereby enhancing the effect of use.

[0003] However, microneedle components cannot be reused. In related technologies, the microneedle structure includes a support and a microneedle component fixedly mounted on the support. The microneedle component is a disposable item and cannot be replaced individually. The entire microneedle structure needs to be replaced after each use, which results in high production costs. Utility Model Content

[0004] This application provides a microneedle structure that optimizes the mounting structure of the microneedle assembly to reduce the cost of using the microneedle structure.

[0005] On one hand, embodiments of this application provide a microneedle structure, including: a scaffold;

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Additionally, the use of "based on" implies openness and inclusivity, because processes, steps, calculations, or other actions "based on" one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0036] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0037] On the one hand, such as Figures 1 to 6 As shown, this application provides a microneedle structure, including a support 10, a connecting shaft 20, and a microneedle assembly 30; the connecting shaft 20 is fixed to the support 10; the microneedle assembly 30 includes a sleeve 31 and a microneedle 32, the microneedle 32 protruding from the outer peripheral wall of the sleeve 31, the sleeve 31 being detachably sleeved on the connecting shaft 20, and the sleeve 31 being rotatably disposed relative to the connecting shaft 20.

[0038] In this embodiment, the microneedle assembly 30 includes a sleeve 31 and microneedles 32 disposed on the outer peripheral wall of the sleeve 31. Before using the microneedle structure, the sleeve 31 is fitted onto the connecting shaft 20, allowing the sleeve 31 to rotate relative to the connecting shaft 20. The support 10 pushes the sleeve 31 to roll on the user's skin, enabling the microneedles 32 on the sleeve 31 to puncture the skin. After use, the microneedle assembly 30 will be contaminated with the user's bodily fluids and skin flakes. After use, the sleeve 31 can be removed from the connecting shaft 20 for disinfection and cleaning or directly replaced. This design facilitates the disassembly of the microneedle assembly 30, allowing for the replacement of disposable microneedle assemblies for continued use without the need to replace the entire microneedle structure, thereby reducing the cost of each use.

[0039] The sleeve 31 has multiple microneedles 32 on its surface. Each microneedle 32 is annular, with multiple microneedles distributed along the circumference of the annulus. The multiple microneedles 32 are arranged together on the sleeve 31, with the microneedles protruding from the outer circumferential wall of the sleeve 31. Furthermore, the sleeve 31 is composed of multiple fixing rings 311 and fixing bushings 312. The fixing rings 311 are hollow rings, and multiple fixing rings 311 are sleeved on the fixing bushings 312. A microneedle 32 is clamped between any two adjacent fixing rings 311. Multiple fixing rings 311 and microneedles 32 are placed sequentially along the axial direction of the fixing bushings 312. At the tail end of the fixing bushings 312, a fixing ring 311 presses the microneedle 32 against the flange 62 of the fixing bushings 312. Adhesive can also be added to the contact surface between the fixing rings 311 and the microneedles 32 to further fix the fixing rings 311 and the microneedles 32.

[0040] In some embodiments, such as Figure 4 As shown, the bracket 10 has a protruding mounting arm 11, which is set at an angle to the bracket 10, and the connecting shaft 20 protrudes from the mounting arm 11.

[0041] Specifically, a mounting arm 11 protrudes from the top of the bracket 10, extending in an L-shape. The short side of the mounting arm 11 connects to the bracket 10, and the long side extends upward. A connecting shaft 20 protrudes from the long side of the mounting arm 11, with the short and long sides forming a 90-degree angle. The connecting shaft 20 is perpendicular to the long side of the mounting arm 11. A space for mounting the microneedle assembly 30 is formed between the mounting arm 11 and the bracket 10. The sleeve 31 in the microneedle assembly 30 is fitted onto the connecting shaft 20. This configuration allows the sleeve 31 to be removed and replaced from the side without the mounting arm 11. In embodiments where the connecting shaft 20 is clamped between the two arms, this improves the ease of assembly and disassembly of the sleeve 31. In other embodiments, the bracket 10 has a U-shaped groove, and the two ends of the connecting shaft 20 are respectively inserted into the two opposite sidewalls of the U-shaped groove, with the sleeve 31 fitted onto the connecting shaft 20.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the microneedle structure also includes a limiting end plate 40, which is disposed at the end of the connecting shaft 20 away from the mounting arm 11. The limiting end plate 40 is used to limit the movement of the sleeve 31 in the axial direction of the connecting shaft 20.

[0043] Specifically, the limiting end plate 40 is located at the end of the connecting shaft 20 away from the mounting arm 11. Both ends of the sleeve 31 are spaced apart from the mounting arm 11 and the limiting end plate 40. The mounting arm 11 and the limiting end plate 40 are mainly used to limit the axial movement of the sleeve 31. Under the combined limiting effect of the two, the sleeve 31 will not fall off the connecting shaft 20. This arrangement increases the installation stability of the sleeve 31 and prevents the sleeve 31 from falling off the connecting shaft 20 during rolling.

[0044] Furthermore, there are several ways to replace the sleeve 31. The sleeve 31 can be removed by removing the connecting shaft 20, or the sleeve 31 can be removed by removing the limiting end plate 40. Alternatively, the sleeve 31 can be made into a spliced ​​form, and the sleeve 31 can be directly disassembled for replacement.

[0045] In some embodiments, the limiting end plate 40 is detachably fixed to the end of the connecting shaft 20 away from the mounting arm 11.

[0046] Specifically, the limiting end plate 40 is detachable from the connecting shaft 20. Before using the microneedle structure, the limiting end plate 40 is removed, the sleeve 31 is fitted onto the connecting shaft 20, and then the limiting end plate 40 is installed. This arrangement facilitates the assembly and disassembly of the microneedle assembly 30 and prevents it from coming into contact with other structures during the assembly and disassembly process. In some other embodiments, the end of the connecting shaft 20 away from the limiting end plate 40 is detachably fixed to the mounting arm 11.

[0047] In some embodiments, the limiting end plate 40 is provided with a protrusion 41 on the side facing the connecting shaft 20. The protrusion 41 is provided with an external thread, and the free end of the connecting shaft 20 is provided with a threaded hole 21. The protrusion 41 is screwed into the threaded hole 21 to fix the limiting end plate 40. The free end of the connecting shaft 20 is the end of the connecting shaft 20 away from the mounting arm 11.

[0048] Specifically, a protruding post 41 is provided on the side of the limiting end plate 40 facing the connecting shaft 20. The outer peripheral wall of the protruding post 41 is threaded. A concave threaded hole 21 is provided at the end of the connecting shaft 20 that connects to the limiting end plate 40. The protruding post 41 is screwed into the threaded hole 21 to fix the limiting end plate 40 and the connecting shaft 20. This threaded connection is simple and makes it easier to assemble and disassemble the limiting end plate 40. In some other embodiments, a magnetic suction component is provided on the limiting end plate 40, and a corresponding magnetic suction component is provided at the end of the connecting shaft 20. The magnetic suction components at both ends attract each other to realize the installation of the limiting end plate 40. Alternatively, a threaded hole 21 can be opened on the limiting end plate 40, and a partial thread can be provided on the outer peripheral wall of the connecting shaft 20 to connect the limiting end plate 40 and the connecting shaft 20 by screwing. Alternatively, multiple fixing rubber rings can be sleeved on the outer peripheral wall of the protruding post 41, and an installation hole can be opened on the connecting shaft 20. The protruding post 41 is inserted into the installation hole with an interference fit.

[0049] Furthermore, such as Figure 8The limiting end plate 40 shown is also provided with a plurality of reinforcing ribs 42 on the side facing the sleeve 31. The reinforcing ribs 42 extend from the edge of the limiting end plate 40 toward the center. The height of the reinforcing ribs 42 is slightly lower than that of the protruding column 41. Since the limiting end plate 40 needs to be frequently disassembled and assembled, the reinforcing ribs 42 are used to enhance the structural strength and prevent damage during use.

[0050] In some embodiments, such as Figure 3 , Figure 4 and Figure 8 As shown, the microneedle structure includes a lamp plate 50, which is fixed to the connecting shaft 20. The sleeve 31 is made of a light-transmitting material, and the light emitted by the lamp plate 50 is transmitted through the sleeve 31.

[0051] Specifically, a light panel 50 is mounted on the connecting shaft 20. The light panel 50 emits light outward, which passes through the transparent sleeve 31 and shines onto the user's skin. This also illuminates the entire microneedle assembly 30. The LEDs on the light panel 50 emit different wavelengths of red, yellow, or blue light, allowing the light emitted to be adjusted according to user needs. In this embodiment, the LEDs emit red light. During microneedling treatment, skincare products are applied to the sleeve 31. When needles are inserted into the skin, the skincare products penetrate the subcutaneous tissue. The red light enhances the efficacy of the skincare products and accelerates skin repair, promoting epidermal cell renewal. This configuration improves the effectiveness of the microneedle structure and enhances the user experience. In other embodiments, the microneedle structure includes a light panel 50 and a lens. The light panel 50 is mounted on the bracket 10, and a lens is positioned on the front of the light panel 50. The lens refracts the light emitted from the light panel 50 onto the microneedle assembly 30.

[0052] In some embodiments, such as Figure 3 and Figure 4 The connecting shaft 20 shown is a hollow shaft. The lamp plate 50 is installed inside the connecting shaft 20. The connecting shaft 20 is provided with multiple light-transmitting holes 22. The light-transmitting holes 22 are set one-to-one with the lamp beads on the lamp plate 50, and the lamp beads are exposed through the light-transmitting holes 22.

[0053] Specifically, a blind hole is drilled at one end of the connecting shaft 20 that connects to the mounting arm 11. This blind hole extends towards the limiting end plate 40 and is not connected to the threaded hole 21 at the other end of the connecting shaft 20. A lamp plate 50 and a battery 51 supplying power to the lamp plate 50 are disposed within the blind hole. Light-transmitting holes 22 are provided on the outer peripheral wall of the connecting shaft 20, with each light-transmitting hole corresponding to a specific LED. This arrangement allows the lamp plate 50 used for phototherapy to be housed within the connecting shaft 20, improving space utilization and reducing the overall size. Furthermore, the light-transmitting holes 22 ensure that each LED does not interfere with the others, allowing light to be emitted evenly, thus ensuring stable phototherapy effects. In some other embodiments…

[0054] Furthermore, a circuit board 17 for controlling the microneedle structure is provided inside the bracket 10. A button 16 is electrically connected to the circuit board 17. The button 16 is used to control the switch of the microneedle structure, and a spring pin is provided on the button 16 for charging the microneedle structure. That is, when the microneedle structure is not in use, the charger can be magnetically connected to the spring pin for charging. The circuit board 17 is electrically connected to the battery 51 and the lamp board 50.

[0055] In another embodiment, the connecting shaft 20 is a hollow shaft, the lamp plate 50 is installed inside the connecting shaft 20, the connecting shaft 20 is made of a light-transmitting material, and the light emitted by the lamp plate 50 can pass through the hollow shaft and the sleeve 31 before being emitted.

[0056] Specifically, the connecting shaft 20 is made of transparent material, and the lamp board 50 is installed inside the connecting shaft 20. When the lamp bead emits light, it can emit light outward through the connecting shaft 20. This setting can also achieve the purpose of illuminating the light outward.

[0057] In some embodiments, multiple lamp panels 50 are provided, and the multiple lamp panels 50 are evenly spaced along the circumference of the connecting shaft 20.

[0058] Specifically, in this embodiment, at least two light panels 50 are provided, spaced apart from each other and arranged at an angle. During use, they emit light simultaneously, resulting in a larger light emission range. This arrangement ensures that the skincare product on the sleeve 31 is illuminated by light as much as possible, while also increasing the phototherapy area on the skin, thereby improving the user experience. In other embodiments, the light panels 50 are flexible, spirally arranged within the connecting shaft 20 to irradiate in the circumferential direction of the connecting shaft 20.

[0059] Furthermore, the light panel 50 can be installed at various points on the bracket 10, either inside the mounting arm 11 or at the lower end of the mounting arm 11. The bracket 10 can be configured as a light-transmitting structure so that the light panel 50 can illuminate more areas, thereby improving the aesthetics of the product. It can also be used alone for phototherapy, enhancing the user experience.

[0060] In some embodiments, such as Figure 6 As shown, the microneedle structure includes a bushing 60, which is fixedly sleeved on the connecting shaft 20. The microneedle assembly 30 is movably sleeved on the bushing 60. The outer peripheral wall of the bushing 60 is provided with an abutting protrusion 61, which extends in a ring shape along the circumference of the connecting shaft 20. The outer wall surface of the abutting protrusion 61 is used to abut against the inner peripheral wall of the sleeve 31.

[0061] Specifically, a bushing 60 is fixedly fitted onto the connecting shaft 20. The outer peripheral wall of the bushing 60 is provided with two abutting protrusions 61. The abutting protrusions 61 extend in a ring shape along the circumference of the bushing 60. The sleeve 31 is fitted onto the bushing 60. The outer wall of the abutting protrusion 61 is used to abut against the inner wall of the sleeve 31. There are at least two abutting protrusions 61. The two abutting protrusions 61 are respectively located at two far apart ends on the bushing 60. One abutting protrusion 61 is close to the flange 62 of the bushing 60, and the other abutting protrusion 61 is close to the end of the bushing 60. This arrangement can reduce the radial vibration of the sleeve 31 when it rotates, thereby ensuring the rolling stability of the sleeve 31.

[0062] In some embodiments, such as Figure 4 and Figure 7 As shown, the support 10 is provided with a liquid outlet 12 spaced apart from the sleeve 31. The liquid outlet 12 is connected to the liquid storage container 70 and is used to discharge the liquid in the liquid storage container 70 to the surface of the sleeve 31.

[0063] Specifically, the support 10 is mounted on the liquid reservoir 70, which contains medication or skincare products. When using the microneedle structure, the liquid in the reservoir 70 flows onto the microneedle assembly 30. When the sleeve 31 rolls, the liquid flows across its surface. When the microneedle 32 punctures the skin, the liquid flows from the microneedle 32 into the skin for microneedle treatment. Compared to traditional microneedle treatment, this setup eliminates the need for prior skin puncture and application of medication or skincare products, reducing operational steps and improving the efficiency of microneedle treatment. In other embodiments, the connecting shaft 20 has a liquid outlet channel, and the sleeve 31 has multiple capillaries connected to the liquid outlet channel. The liquid outlet channel guides the liquid from the reservoir 70 into the capillaries, which are located on the surface of the sleeve 31 and output the liquid to the outer surface of the sleeve 31.

[0064] In some embodiments, such as Figure 2 and Figure 8 As shown, the support 10 is provided with an air inlet 13 spaced apart from the liquid outlet 12. The support 10 includes an air guide pipe 14, which connects the air inlet 13 and the liquid storage container 70. The air inlet 13 is used to introduce air into the liquid storage container 70.

[0065] Specifically, the support 10 is provided with an air inlet 13, and an air guide pipe 14 is connected to the air inlet 13. The air guide pipe 14 extends into the liquid storage container 70. The support 10 is also provided with a liquid outlet 12. The two liquid outlets 12 and the air inlet 13 are arranged side by side on a nozzle assembly 15. The nozzle assembly 15 includes three conical nozzles protruding from the support 10. The three nozzles correspond to the three outlets respectively. The air inlet 13 is sandwiched between the two liquid outlets 12. With this arrangement, air can enter the liquid storage container 70 through the air inlet 13 to balance the pressure difference inside and outside, thereby ensuring that the liquid outlet 12 can output liquid normally.

[0066] In some embodiments, at least a portion of the microneedle assembly 30 is made of a conductive material, enabling physical therapy on human skin when the microneedle assembly 30 is energized.

[0067] Specifically, at least one of the sleeve 31 and the microneedle 32 in the microneedle assembly 30 is made of a conductive material, or both can be made of conductive materials. The conductive materials used to fabricate the sleeve 31 and the microneedle 32 in this application can be conductive materials known in the art. For example, conductive materials can include metallic conductive materials such as copper, iron, aluminum, gold, silver, or stainless steel, as well as non-metallic conductive materials such as conductive plastics, conductive rubber, or conductive silicone. The microneedle structure also includes a conductive element. When the sleeve 31 or the microneedle 32 is made of a conductive material, the conductive element is electrically connected to one of the conductive structures, thereby enabling the microneedle assembly 30 to be energized. When both the sleeve 31 and the microneedle 32 are conductive materials... During manufacturing, the conductive component can be arbitrarily connected to either the connecting shaft 20 or the support 10. One end of the conductive component is electrically connected to the circuit board. When positioned on the connecting shaft 20, the conductive component is configured as a conductive ball bearing protruding from the outer peripheral wall of the connecting shaft 20. A conductive groove is provided on the inner peripheral wall of the sleeve 31. When the sleeve 31 is fitted onto the connecting shaft 20, the conductive ball bearing is embedded in the conductive groove, enabling energization of the sleeve 31 and the microneedle 32. Alternatively, the conductive component can be positioned on the side of the mounting arm 11 where the connecting shaft 20 is located. When the sleeve 31 is fitted onto the connecting shaft 20, the end of the sleeve 31 can contact the conductive component on the side wall of the mounting arm 11, thereby achieving energization. When energized, the microneedle 32 contacts the human skin, enabling microcurrent therapy and radiofrequency therapy. This configuration increases the functionality of the microneedle structure of this application, thereby meeting the needs of more users and improving the user experience.

[0068] On the other hand, reference Figure 7 and Figure 8 This application provides a physiotherapy component, including a microneedle structure as described above and a liquid reservoir 70 for storing liquid, with a support 10 detachably mounted on the liquid reservoir 70.

[0069] Specifically, the support 10 is screwed to the liquid storage container 70. Before use, the medicine or skin care product to be introduced into the skin can be put into the liquid storage container 70. The microneedle component 30 is rolled on the skin to achieve skin puncture. While rolling, the medicine or skin care product can also be introduced into the skin, making the operation convenient for users and improving the user experience.

[0070] The microneedle structure provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
