[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0031] As described in the background section, during electrostimulation therapy, microneedle patches are attached to corresponding locations on the body to perform the treatment. Existing devices suffer from limitations in needle hub structure and dense needle arrangement, leading to difficulties in needle shaping.
[0032] Please refer to Figure 1 The microneedle patch device 100 provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.
[0033] The microneedle patch device 100 includes a needle holder 110 and a needle body 120; wherein, the needle holder 110 is densely provided with perforated holes 111, and the needle body 120 is densely provided on the needle holder 110 and is arranged in a one-to-one correspondence with the perforated holes 111, and the extension direction of the needle body 120 is arranged at an angle to the needle holder 110.
[0034] During the manufacturing process, by densely setting hollow holes 111 on the needle holder 110 and corresponding one-to-one with the needle body 120, and setting the needle body 120 and the needle holder 110 at an angle, the activity space during the molding process can be increased when the needle body 120 is arranged densely, thereby improving the molding convenience of the needle body 120.
[0035] It is worth noting that the needle body 120 can be a separate structure from the needle base 110, and can be connected to the needle base 110 after the needle base 110 is formed; or the needle body 120 can be integrally formed with the needle base 110, and can be formed by stamping on the basis of the needle base 110, thereby combining the forming process of the needle body 120 with the forming process of the hollow hole 111, further improving the forming efficiency.
[0036] refer to Figure 1 and Figure 2 An extension plate 112 is formed between any two adjacent perforated holes 111, and the needle body 120 is connected to the extension plate 112, thereby ensuring that the needle body 120 can be provided with sufficient support so that the needle body 120 will not easily deviate when it is inserted into the human body.
[0037] In this embodiment, the perforated hole 111 is hexagonal in shape, and the multiple extension plates 112 are honeycomb mesh structures. By forming a honeycomb mesh structure, the arrangement density of the needles 120 connected to the extension plates 112 can be increased, and the overall structural strength can be improved, thereby facilitating better treatment results for patients.
[0038] Of course, in other embodiments of this utility model, the hollow hole 111 can also be a rectangle, rhombus, pentagon or other shapes, and the specific shape of the hollow hole 111 is not limited.
[0039] Furthermore, to ensure treatment effectiveness, the height of the needle body 120 can be 700um to 900um. Specifically, its height can be 700um, 750um, 800um, 850um, 900um, etc., preferably 800um. The number of needle bodies 120 can be 40 to 50, specifically 40, 42, 44, 45, 46, 48, 50, etc., preferably 43. Regarding the material of the needle body 120, SS316L medical-grade stainless steel is preferred, thus minimizing negative impacts on the patient during treatment.
[0040] Regarding the planar area of the needle holder 110, it can be specifically 0.8 cm². 2 ~1.2cm 2 Specifically, its area can be 0.8 cm². 2 0.9cm 2 1.0cm 2 1.1cm 2 1.2cm 2 Preferably, the planar area of the needle holder 110 can be 1.0 cm². 2 .
[0041] During treatment, the needle hub 110 can be attached to the inside of the patient's ankle according to the operating instructions, and the needle body 120 punctures the stratum corneum of the skin. Electrical energy is supplied to the needle body 120 through the power supply device, releasing an electrical stimulation with an intensity of 1.2mA to 5.0A, a frequency of 1Hz to 10Hz, and a pulse width of 10µs to 570µs, giving the body a reverse electrical signal, thereby eliminating damage or fatigue caused by excessive activity.
[0042] refer to Figure 1 In order to improve the forming efficiency of multiple needles 120, each needle 120 can be located on the same side of the corresponding hollow hole 111.
[0043] Because both the perforated holes 111 and the needles 120 are densely arranged, placing the needles 120 on the same side of the perforated holes 111 facilitates the simultaneous forming of multiple needles 120, thus improving forming efficiency. Furthermore, it makes the spacing between any two adjacent needles 120 more stable, and the density of needles 120 in different areas more balanced, thereby preventing uneven distribution of the needles 120.
[0044] refer to Figure 1 and Figure 2In order to improve the process performance of the needle body 120, a needle hole 121 can be opened on the needle body 120. On the one hand, this helps to reduce the weight of the needle body 120, and on the other hand, it can improve the permeability between adjacent needle bodies 120.
[0045] Furthermore, two connecting ribs 122 are formed at the bottom of the needle body 120. The connecting ribs 122 are connected to the needle seat 110, and the needle hole 121 is opened between the two connecting ribs 122.
[0046] In this embodiment, the pinhole 121 is elongated; of course, in other embodiments of this utility model, the pinhole 121 may be circular, fan-shaped, elliptical, or prismatic, etc., and the specific shape of the pinhole 121 is not limited.
[0047] In this embodiment, the number of pinholes 121 is one; of course, in other embodiments of this utility model, the number of pinholes 121 can be two, three, four, etc., and the specific number of pinholes 121 is not limited.
[0048] Furthermore, the tip of the needle body 120 has a sharp angle, and the two sides of the sharp angle are arc-shaped with the arc curving direction facing the inside of the needle body 120, which facilitates the penetration of the stratum corneum of the skin, thereby reducing the resistance encountered during the puncture process, improving the puncture efficiency, and minimizing the discomfort caused to the patient.
[0049] Specifically, the connecting rib 122 is connected to the extension plate 112. By forming two connecting ribs 122, the connection strength between the needle body 120 and the extension plate 112 can be ensured under the premise of having a needle hole 121, and the needle body 120 is prevented from easily deflecting relative to the extension plate 112.
[0050] Furthermore, to further improve connection stability, the number of connecting ribs 122 can be three, four, or five, and pinholes 121 can be formed between two adjacent connecting ribs 122. The specific number of connecting ribs 122 is not limited.
[0051] refer to Figure 2 In order to further improve the connection strength between the connecting rib 122 and the extension plate 112, the connecting rib 122 can be formed with a first arc surface 1221 and a second arc surface 1222 on the sides of the connecting rib 122 that are close to and away from the corresponding hollow hole 111, thereby improving the strength of the connection between the connecting rib 122 and the extension plate 112 and preventing the connecting rib 122 from easily deflecting towards or away from the hollow hole 111 relative to the extension plate 112.
[0052] refer to Figure 2Because the distance between the two sides of the extension plate 112 and the connecting rib 122 is not equal, the connecting rib 122 will usually be closer to its corresponding hollow hole 111. Therefore, the connecting rib 122 is more likely to deflect away from its corresponding hollow hole 111. By limiting the curvature of the second arc surface 1222 to be greater than that of the first arc surface 1221, the deflection of the connecting rib 122 away from its corresponding hollow hole 111 can be avoided as much as possible, thereby making the relative position of the needle body 120 and the needle seat 110 more stable.
[0053] refer to Figure 1 The needle holder 110 is also fixed to its corresponding fixing seat. In order to improve the relative positional stability between the needle holder 110 and the fixing seat, at least two fixing holes 113 can be opened on the needle holder 110. The at least two fixing holes 113 are close to the edge of the needle holder 110 relative to the needle body 120.
[0054] In the above technical solution, by limiting the fixing hole 113 to be closer to the edge of the needle holder 110, the negative impact of the opening of the fixing hole 113 on the arrangement of the needle body 120 can be avoided, and it helps to make a reasonable distance between the fixing hole 113 and the hollow hole 111, so as to avoid negative impact on the structural strength of the overall needle holder 110.
[0055] For the purpose of further improving the stability of the fixing, the number of fixing holes 113 can be at least three, and the at least three fixing holes 113 are arranged in a ring on the needle seat 110.
[0056] Furthermore, in order to make the distribution of the fixing force on the needle holder 110 more uniform, at least three fixing holes 113 can be evenly distributed about the center of the needle holder 110.
[0057] In this embodiment, the needle holder 110 is circular, and the center of the dense arrangement of the multiple hollow holes 111 and the multiple needles 120 coincides with the center of the needle holder 110. Of course, in other embodiments of this utility model, the needle holder 110 can also be rectangular, rhomboid, regular pentagon or other shapes, and the center of the dense arrangement of the multiple hollow holes 111 and the multiple needles 120 can also coincide with the geometric center of the needle holder 110.
[0058] In this embodiment, there are six fixing holes 113, which are evenly distributed on the needle seat 110 near the edge. Of course, in other embodiments of this utility model, the number of fixing holes 113 can be two, three, five, eight, etc., and the specific number of fixing holes 113 is not limited.
[0059] In summary, the microneedle patch device 100 provided by the embodiments of this utility model has at least the following advantages:
[0060] (1) The microneedle patch device 100 has densely arranged hollow holes 111 on the needle seat 110 and corresponds one-to-one with the needle body 120. The needle body 120 and the needle seat 110 are arranged at an angle. This can increase the activity space in the molding process when the needle body 120 is arranged densely, thereby improving the molding convenience of the needle body 120.
[0061] (2) The microneedle patch device 100 forms an extension plate 112 between any two adjacent hollow holes 111, and the needle body 120 is connected to the extension plate 112, thereby ensuring that the needle body 120 can be provided with sufficient support so that the needle body 120 will not easily deviate when inserted into the human body.
[0062] (3) The microneedle patch device 100 is in the shape of a regular hexagon with defined hollow holes 111 and multiple extension plates 112 in the shape of a honeycomb mesh. This not only makes the arrangement density of the needles 120 connected to the extension plates 112 greater, but also improves the overall structural strength, thereby facilitating better treatment effects on the human body.
[0063] (4) The microneedle patch device 100 makes each needle 120 located on the same side of the corresponding hollow hole 111, which facilitates the simultaneous molding of multiple needles 120 and can improve the molding efficiency of multiple needles 120; it can also make the spacing between any two adjacent needles 120 equal, so that the arrangement density of needles 120 in different areas is relatively balanced, thereby preventing the needles 120 from being unevenly arranged.
[0064] (5) The microneedle patch device 100 forms two connecting ribs 122 at the bottom of the needle body 120, which can ensure the connection strength between the needle body 120 and the extension plate 112 under the premise of opening the needle hole 121, and prevent the needle body 120 from easily deflecting relative to the extension plate 112.
[0065] (6) The microneedle patch device 100 forms a first arc surface 1221 and a second arc surface 1222 on both sides of the connecting rib 122, and makes the curvature of the second arc surface 1222 greater than that of the first arc surface 1221. This can prevent the connecting rib 122 from deflecting away from the corresponding hollow hole 111 as much as possible, thereby making the relative position of the needle body 120 and the needle seat 110 more stable.
[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
