In some embodiments, the manner of disposing the cathode and the anode on the surface of the needle body may include the following:

mode 1: the surface of the needle body is provided with a cathode and an anode.

As shown in fig. 2, the cathode 31 and the anode 32 may each be provided with one, and in this case the cathode 31 and the anode 32 may be provided on opposite sides of the central axis of the needle 22, which is represented as a point and denoted as a in fig. 2 due to the problem of the view angle in fig. 2. Alternatively, the cathode 31 and the anode 32 may be arranged along the extending direction of the needle 22, and further may be spirally wound along the surface of the needle 22, as shown in (a) of fig. 4, the extending direction of the needle 22 being the F2 direction. Therefore, the primary cell structure can be realized by manufacturing fewer cathodes 31 and anodes 32, double stimulation to acupuncture points is realized on the basis of simplifying manufacturing difficulty and reducing manufacturing cost, and the treatment effect of the pressing needle is improved.

Alternatively, the cathode 31 and the anode 32 may each be provided in plural, and the cathode 31 and the anode 32 may be alternately provided so that adjacent cathode 31 and anode 32 form a primary cell in the vicinity. Of course, the cathodes 31 and the anodes 32 may be alternately arranged, that is, the cathodes 31 and the anodes 32 may be randomly arranged, so as to improve design flexibility. The number of the cathodes 31 and the anodes 32 may be the same or different, and may be set according to actual conditions, and is not limited herein. Further, as shown in (c) of fig. 4, the cathode 31 and the anode 32 may be arranged along the circumferential direction of the needle 22, wherein the circumferential direction is the F1 direction; or as shown in fig. 4 (a) and (b), the cathode 31 and the anode 32 may be arranged along the extending direction (i.e., the F2 direction) of the needle 22, and may be further configured to: the cathode 31 and the anode 32 are spirally wound around the surface of the needle 22 (as shown in fig. 4 (a)), or non-spirally wound around the surface of the needle 22 (as shown in fig. 4 (b)). Therefore, a plurality of primary cell structures can be obtained, the arrangement modes of the cathodes and the anodes in the primary cell structures are different, and the directions of electric fields generated between the cathodes and the anodes in the primary cell structures are different, so that the novel press needle can adapt to different subcutaneous tissues, and the application range of the press needle is widened. It should be understood that the arrangement of the cathode 31 and the anode 32 is not limited to that shown in fig. 2 and 4, and all arrangements are within the scope of the embodiments of the present invention as long as the structure of the primary battery can be realized.

And the cathode and the anode can be made of metal materials or metal alloy materials with biocompatibility, for example, but not limited to, the cathode can be made of inert metal (such as silver and the like), the anode can be made of active metal (such as magnesium and the like), and the damage to skin caused by a pressing needle in the using process can be avoided on the basis of realizing a primary cell. Wherein, the cathode and the anode can be manufactured on the surface of the needle body by adopting methods such as magnetron sputtering, vapor deposition, coating, spraying and the like.

Also, in this mode 1, the needle body 22 may be made of a biocompatible and conductive metal material or metal alloy material, for example, the snapper body may be, but not limited to, a medical snapper, in which case the snapper body has conductivity. Based on this, as shown in fig. 2, an insulating layer 40 may be provided between the needle 22 and the cathode 31 and anode 32, and the insulating layer 40 may realize insulation of the needle 22 from the cathode 31 and insulation of the needle 22 from the anode 32. Of course, the needle body 22 may be made of an insulating material with biocompatibility, so that the snap needle body is not conductive, at this time, the insulating layer 40 is not required to be disposed on the surface of the needle body 22, and the cathode 31 and the anode 32 may be directly fabricated on the surface of the needle body 22, so that insulation between the cathode 31 and the anode 32 and the needle body 22 may be achieved. The insulating layer 40 may be made of a polymer material having biocompatibility, such as, but not limited to, polyurethane, polyvinyl alcohol, polydimethylsiloxane (abbreviated as PDMS), etc.

In this mode 1, the construction principle of the primary battery includes:

the needle body can penetrate epidermis and dermis to enter subcutaneous tissue when penetrating into skin, a large amount of body fluid and cells are arranged in the subcutaneous tissue, and when the cathode 31 and the anode 32 are contacted with the body fluid, the body fluid can serve as electrolyte 50 to transfer ions for the cathode 31 and the anode 32; ions such as iron ions and potassium ions exist in the cells, and when the cathode 31 and the anode 32 are in contact with the cells, the cells can serve as the lead 60 connecting the cathode 31 and the anode 32, wherein the ions can transfer electrons to the cathode 31 and the anode 32, thereby constituting the structure of the primary cell shown in fig. 5. Taking the cathode 31 made of metallic silver and the anode 32 made of metallic magnesium as an example, the reduction reaction of the cathode 31 may include: o (O) ₂ +2H ₂ O+4e ^- →4OH ^- ，2H ⁺ +2e ^- →H ₂ The method comprises the steps of carrying out a first treatment on the surface of the The oxidation reaction occurring at anode 32 may include: mg-2e ^- →Mg ²⁺ . Thus, when the redox reaction occurs, chemical energy can be converted into electric energy, and then electric current generated in the lead 60 connecting the cathode 31 and the anode 32 can discharge cells when the cells are used as the lead 60 connecting the cathode 31 and the anode 32, thereby realizing electric stimulation, enhancing the stimulation of the channels and improving the therapeutic effect of the pressing needle.

Mode 2: the surface of the needle body is provided with an anode.

It should be understood that, in this embodiment 2, since the needle 22 has conductivity, the surface of the needle 22 is provided with the insulating layer 40, and the insulation between the needle 22 and the anode 32 is achieved by the insulating layer 40.

Wherein, as shown in fig. 3, only one anode 32 may be provided, and the anode 32 may be wrapped around the surface of the needle 22; of course, the anode 32 may not wrap around the surface of the needle 22, as long as the anode 32 is disposed on the surface of the needle 22, and the specific structure is not limited herein. Thus, the primary cell structure can be realized by manufacturing fewer anodes 32, double stimulation to acupuncture points is realized on the basis of simplifying manufacturing difficulty and reducing manufacturing cost, and the treatment effect of the pressing needle is improved.

Alternatively, the anode 32 may be provided in plurality, and the respective anodes 32 may be arranged along the circumferential direction of the needle 22 (the F1 direction as shown in fig. 6) or along the extending direction of the needle 22 (the F2 direction as shown in fig. 6); and, when arranged along the extending direction of the needle body 22, may further be configured to: spirally wound around the surface of the needle body 22 (as shown in fig. 6 (a)), or non-spirally wound around the surface of the needle body 22 (as shown in fig. 6 (b)). Therefore, a plurality of primary cell structures can be obtained, the arrangement modes of the cathodes and the anodes in the primary cell structures are different, and the directions of electric fields generated between the cathodes and the anodes in the primary cell structures are different, so that the novel press needle can adapt to different subcutaneous tissues, and the application range of the press needle is widened.

And, the anode can be made of a biocompatible, chemically active and conductive metal (such as but not limited to magnesium) or metal alloy material to avoid damage to the skin during use of the snapper. Wherein, the anode can be manufactured on the surface of the needle body by adopting methods such as magnetron sputtering, vapor deposition, coating, spraying and the like.

Mode 3: the surface of the needle body is provided with a cathode.

Only when the cathode is made of a material selected, the material may be selected according to the desired cathode effect.

In summary, the above modes 1 to 3 are three cathode and anode setting modes, and can be specifically selected according to actual needs, so as to meet the needs of different application scenarios.

In some embodiments, as shown in fig. 6 (c), the needle body 22 may include a central portion 22a and a needle head 22b connected, the central portion 22a may be connected to a needle handle (not shown) and the needle head 22b, and a cathode (not shown) and/or an anode 32 may be provided on a surface of the central portion 22 a. This exposes the needle 22b so that the needle 22b can be easily penetrated into the skin, thereby preventing the penetration effect from being affected when the cathode and/or anode 32 wraps the needle 22b, and improving the convenience of operation.

In some embodiments, the needle handle may be disposed outside the friction nano-generator, that is, the pressing needle body and the friction nano-generator are in two structures separately disposed, at this time, the needle handle may be fixed on the medical adhesive tape, the pressing needle body may be fixed by the medical adhesive tape, and the needle handle and the friction nano-generator may be connected by a wire, so as to realize electrical connection between the needle handle and the friction nano-generator, and thus, the alternating current output by the friction nano-generator is transmitted to the needle handle.

Alternatively, as shown in fig. 1, the friction nano-generator 10 may include: the skin-friendly layer 11 and the power generation structure 12 arranged above the skin-friendly layer 11, the needle handle 21 can also be arranged between the skin-friendly layer 11 and the power generation structure 12, and the needle body 22 can pass through the skin-friendly layer 11. Thus, the needle handle 21 can be fixed in the friction nano generator 10, and the pressing needle body 20 and the friction nano generator 10 are assembled into a whole structure, so that the pressing needle body 20 is fixed, and meanwhile, the pressing needle can be conveniently used.

As shown in fig. 7, the skin-friendly layer 11 may further include: the base layer 11a and the adhesive layer 11b, the base layer 11a may be made of an antibacterial, breathable, flexible material for carrying the power generation structure 12; the adhesive layer 11b may be made of medical adhesive tape for attaching to the skin.

Of course, the skin-friendly layer can also be a layer structure, no illustration is given, at the moment, the skin-friendly layer can be used as a basal layer to bear the power generation structure, and meanwhile, the skin-friendly layer can also have cohesiveness so as to be attached to the surface of the skin, so that the structure of the friction nano-generator is simplified, the number of membrane layers penetrated by a needle body is reduced, the length of the needle body penetrating out of the skin-friendly layer is prolonged, and the stimulation to acupuncture points is enhanced.

In some embodiments, the shape of the needle handle is not limited to that shown in fig. 7, and may be triangular, clip-shaped or special in practical cases, so long as the shape of the needle handle is convenient to fix, which falls within the scope of the embodiments of the present invention.

In some embodiments, the friction nano-generator may be in a single electrode mode, as shown in fig. 7, where the power generation structure 12 may include: the friction layer 12a and the electrode layer 12b are arranged in a laminated manner, the electrode layer 12b is positioned between the friction layer 12a and the skin-friendly layer 11, a needle handle (shown in a virtual loop in fig. 7) can be arranged between the electrode layer 12b and the skin-friendly layer 11, and when the pressing needle body 20 is made of conductive materials, the needle handle is in direct contact with the electrode layer 12b, so that the electrical connection between the needle handle and the friction nano-generator 10 can be realized, and the structure of the pressing needle is simplified.

Thus, when the human body part or clothes and the like rub (i.e. contact and separate) with the friction layer, electrons can be transferred on the surface of the friction layer, corresponding charges are induced on the electrode layer under the action of contact electrification and electrostatic induction, and when the electrode layer is electrically connected with the needle handle, the charges of the electrode layer can be transmitted into the needle handle so as to generate current. If a forward current (or a reverse current) is output to the needle handle when the human body part or the clothing or the like is separated from the friction layer, a reverse current (or a forward current) may be output to the needle handle when the human body part or the clothing or the like is again contacted with the friction layer, so that an alternating current may be output to the needle handle. And along with the continuous progress of friction, the alternating current is continuously output to the needle handle, thereby realizing the continuous release of the alternating current to the acupuncture points.

Wherein the friction layer can be made of antibacterial, breathable and flexible materials, such as gauze, porous polymer, textile, nanofiber layer made by electrostatic spinning, and the like; the porous polymer may include, but is not limited to, porous PDMS and porous polyvinylidene fluoride (abbreviated as PVDF) and the like, the textile may include, but is not limited to, cotton and linen textiles, and poly fiber textiles and the like, and the raw materials for electrospinning may include, but are not limited to, polyurethane, polyvinyl alcohol, nylon and the like.

In some embodiments, the friction nano-generator may be in a double-electrode mode, where the power generation structure includes two opposite friction structures, and a gap is provided between the two friction structures, where one friction structure may include a friction layer and an electrode layer that are disposed in a stacked manner, and the other friction structure may have the following two arrangements:

the first setting mode is as follows: the other friction structure can also comprise friction layers and electrode layers which are arranged in a laminated mode, the friction layers in the two friction structures are contacted and separated under the action of external force, electrons are transferred to the surfaces of the two friction layers, corresponding charges are induced in the two electrode layers under the action of contact electrification and electrostatic induction, and when one electrode layer is electrically connected with the needle handle, the charges of the electrode layers can be transmitted to the needle handle so as to generate current. Alternating current can be output to the needle handle during the continuous contact and separation of the two friction layers. And along with the continuous contact and separation, alternating current is continuously output to the needle handle, so that the alternating current is continuously released to the acupuncture points.

In the dual-electrode mode friction nano-generator, the friction layer and the electrode layer may be formed of similar materials as those of the single-electrode mode friction nano-generator, regardless of whether the first or second arrangement is adopted, and the materials for forming the friction layer and the electrode layer will not be described in detail herein.

In some embodiments, the friction nano-generator may be sized according to factors such as the location of the acupoint, the size of the electrical stimulation required, etc., such as, but not limited to, 5cm by 5cm or 5cm by 3cm, etc., wherein the larger the size, the stronger the electrical stimulation and the smaller the size, the smaller the electrical stimulation.

In summary, the technical scheme provided by the embodiment of the invention has the following advantages:

1. the Chinese medicine is used for treating the stimulation of the acupuncture points, and has long treatment course and slow effect. In order to solve the problem, the embodiment of the invention provides a novel pressing needle integrating a primary battery technology and a friction nano generator technology, the pressing needle not only relies on the stimulation of the traditional pressing needle to acupuncture points, but also integrates the electrical stimulation mode of primary battery discharge and friction nano generator discharge, and multiple stimulation interactions are realized so as to achieve a better effect.
