Description

Technical Field

[0001] This utility model relates to medical devices, specifically an eye acupuncture rehabilitation needle. Background Technology

[0002] Currently, eye acupuncture is a type of microneedling therapy and a part of acupuncture. It is a method of treating diseases by stimulating specific acupoints around the eye socket. The procedure for eye acupuncture is relatively simple, generally using filiform needles or three-edged needles to stimulate specific acupoints around the eye socket. During acupuncture, the patient needs to close their eyes, and the doctor will select appropriate acupoints and needle depths based on the patient's condition and constitution.

[0003] Existing self-generating press needles, such as the "press needle capable of guiding self-generated chemical current" disclosed in CN205459855U, consist of a press needle, conductive medical tape, and a guidance control layer. The press needle consists of a needle tip and a needle handle, with the needle handle glued and fixed between the conductive medical tape and the guidance control layer. The needle tip protrudes from either the guidance control layer or the conductive medical tape. However, this solution has the following problems: it can only generate extremely weak electrochemical galvanic cell effects, resulting in weak electrical stimulation and a short duration, which is insufficient to meet practical needs. Utility Model Content

[0004] The purpose of this invention is to provide an eye acupuncture rehabilitation needle that fundamentally solves the above-mentioned problems. It has the advantages of simple structure, convenient use, and long stimulation time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The eye acupuncture rehabilitation needle includes a patch assembly and a needle body limited to the center of the patch assembly. The patch assembly includes an insulating film layer, a conductive layer, and an adhesive layer stacked from top to bottom. Its key technical points are:

[0006] It also includes several piezoelectric components fixed on the patch assembly. The piezoelectric component includes a plastic shell, a conductive film, a strip-shaped piezoelectric energy harvester, and a mass block disposed at the end of the piezoelectric energy harvester. A through hole is reserved in the insulating film layer, and the shell passes through the through hole and is limited between the insulating film layer and the conductive layer by the bottom flange. The conductive film is bonded and fixed to the conductive layer.

[0007] The needle body includes a needle shank that is positioned between the conductive layer and the adhesive layer, and a needle tip that protrudes from the adhesive layer.

[0008] Furthermore, the height of each piezoelectric energy harvesting element increases in a gradient.

[0009] Furthermore, the weight of each mass block increases in a gradient.

[0010] Furthermore, a flange is provided at the bottom of the piezoelectric energy harvesting device, which is then positioned between the conductive film and the conductive layer.

[0011] Furthermore, the piezoelectric energy harvesting element is cylindrical or spiral in shape.

[0012] The beneficial effects of this utility model are:

[0013] In terms of overall technical solution, without changing the original method of using the needle lifting device, an array of piezoelectric components that can continuously generate energy are added. When the needle lifting unit is attached to the skin of the acupuncture point, the piezoelectric energy harvesting component deforms under the swinging action as the body moves daily, thereby generating a stimulating current. After being collected by the conductive layer, the current is released from the needle tip to the acupuncture point, effectively prolonging the electrical stimulation time.

[0014] In terms of specific structure, for the needle body, the end of the needle handle is limited and secured by the cooperation of the conductive layer and the adhesive layer, and the needle tip penetrates the adhesive layer to contact the skin.

[0015] For piezoelectric components, by designing the height of each piezoelectric energy harvesting element to increase in a gradient, and using an array of piezoelectric circular diaphragms to harvest energy from broadband vibrations, multiple piezoelectric elements with different mass blocks or different heights can be set up to harvest energy over a wide range of frequencies.

[0016] The design, in which the weight of each mass block or the height of the piezoelectric energy harvester increases in a gradient, enables the piezoelectric energy harvester to achieve higher energy conversion efficiency within a specific frequency range. When the piezoelectric energy harvester is spiral-shaped, the energy output of the piezoelectric effect can be further improved.

[0017] Furthermore, a flange is provided at the bottom of the piezoelectric energy harvester, which is positioned between the conductive film and the conductive layer. This structural design not only ensures the stability of the piezoelectric energy harvester's position during operation but also improves conductivity, preventing signal distortion or energy loss due to poor contact. Simultaneously, the flange structure enhances the bending strength of the piezoelectric energy harvester, further improving its durability.

[0018] By setting through holes in the insulating film layer, the piezoelectric components are securely fixed between the conductive layer and the insulating film layer through the flange at the bottom of the housing. The adhesive layer prevents the energy generated by the piezoelectric energy harvesting components from being directly transferred to the skin. Instead, the energy of multiple piezoelectric components is conducted to the single "exit" needle body through the conductive layer, thereby improving the treatment effect.

[0019] In summary, this invention, through its rational structural design and material layout, significantly improves the performance of piezoelectric energy harvesting devices, enhances the therapeutic effect of eye acupuncture, and provides patients with a better treatment experience.

[0020] Figure 1This is an isometric side view of the present invention.

[0021] Figure 2 This is a structural reference diagram of the present invention. Detailed Implementation

[0022] The following combination Figures 1-2 The specific content of this utility model will be described in detail through specific embodiments. Example 1

[0023] like Figure 2 As shown, the eye acupuncture rehabilitation needle includes several matrix-arranged lifting needle units 4 (eight in this embodiment), with pre-cuts (not marked in the figure) between each lifting needle unit 4 to facilitate quick division during use.

[0024] like Figure 1 As shown, each needle lifting unit 4 includes a patch assembly 2, a needle body 3 limited to the center of the patch assembly 2, and several piezoelectric components 1 fixed on the patch assembly 2 (this embodiment takes four piezoelectric components 1 arranged in an array as an example). The patch assembly 2 adopts a multi-layer structure stacked from top to bottom, consisting of an insulating film layer 21, a conductive layer 22, and an adhesive layer 23, with each layer bonded together by an adhesive (not shown in the figure). The insulating film layer 21 has a through hole 211 for limiting the outer shell 14 of the piezoelectric component 1. The conductive layer 22 can completely cover the conductive film 13 at the bottom of each piezoelectric component 1. The adhesive layer 23 is used to adhere to the skin at the desired acupuncture site. The needle body 3 includes a needle handle 32 limited between the conductive layer 22 and the adhesive layer 23, and a needle tip 31 protruding from the adhesive layer 23.

[0025] The piezoelectric assembly 1 includes a plastic shell 14, a conductive film 13, a strip-shaped piezoelectric energy harvesting element 12, and a mass block 11 disposed at the end of the piezoelectric energy harvesting element 12; the shell 14 passes through the through hole 211 and is limited between the insulating film layer 21 and the conductive layer 22 by the bottom flange 141, and the conductive film 13 is bonded and fixed to the conductive layer 22.

[0026] In this embodiment, each piezoelectric energy harvesting element 12 adopts a hollow cylindrical structure of equal height. A mass block 11 (e.g., plastic or lead block) is bonded and fixed to its top end, and its bottom end is limited to the conductive film 13 by a flange structure (not shown in the figure). The flange structure is limited between the conductive film 13 and the conductive layer 22.

[0027] Working principle of piezoelectric energy harvester 12: When the piezoelectric energy harvester 12 is subjected to an external force along the polarization direction, due to the positive piezoelectric effect, charges are generated on the electrode surface, and the charges accumulate to generate voltage.

[0028] Existing piezoelectric energy harvesting devices include piezoelectric ceramics (such as lead zirconate titanate (PZT)), PVDF, and zinc oxide nanowires. Among them, zinc oxide nanowires are highly flexible and can generate an open-circuit voltage of 3.2V during operation. Although zinc oxide nanowires are highly flexible, they have a relatively low piezoelectric constant; PZT, although having a high piezoelectric constant, is brittle. The piezoelectric energy harvesting device 12 of this invention preferably uses a combination of a flexible PET substrate and PZT fibers, which can generate a peak current of 8μA within a bending effective area (3.5*3.5cm). Example 2

[0029] Based on Example 1, the height of each piezoelectric energy harvester 12 is increased in a gradient, for example, by 10% for each gradient, so that the piezoelectric energy harvester 12 can harvest energy over a wider vibration range. Furthermore, the weight of each mass block 11 can be increased in a gradient, for example, by 10% each time, to change the deformation of the piezoelectric energy harvester 12. Example 3

[0030] Based on Embodiment 1 or 2, the piezoelectric energy harvesting element 12 is changed to a spiral shape to increase its deformation. Example 4

[0031] Furthermore, the number of piezoelectric components 1 can be increased or their arrangement changed as needed. For example, the four piezoelectric components 1 in the array can be changed to a linear distribution; or three piezoelectric components 1 can be used, evenly distributed along the circumference.
