Technical Field

The invention relates to an acupuncture tool, in particular to an electric acupuncture instrument.

Background

Acupuncture is a specific Chinese means for treating diseases, and is a treatment method of treating diseases from the outside to the inside, and the diseases are treated through the action of meridians and acupoints and certain manipulations. Currently, acupuncture has gained almost worldwide acceptance. Acupuncture has been reported to be effective in treating over three hundred diseases, of which over one hundred are reported to be effective.

The traditional Chinese medicine acupuncture and moxibustion in China uses a metal fine needle to penetrate into a human body so as to stimulate acupuncture points on meridians of the human body to achieve the purpose of treatment, the acupuncture and moxibustion treatment has a history of thousands of years in China, is popularized due to simplicity and effectiveness, and has acupuncture doctors all over the world. The needle should be left for a certain time after penetrating into the acupoint to enhance the stimulation effect on the acupoint. In addition, the electric acupuncture therapeutic apparatus has certain pulse current connected to the needle penetrating into human body, so that the stimulation to acupoints is increased and the therapeutic effect is raised.

However, the current electro-acupuncture therapeutic apparatus generally adopts a battery or an external power supply to supply power. When the battery is used for supplying power, if the battery power is exhausted in the treatment process, the patient needs to stop the treatment, the treatment is carried out again after the battery is replaced, and the treatment effect is influenced due to the interruption of the treatment. If an external power supply is used for treatment, the user must perform treatment within a certain position range and cannot move freely due to the limitation of the position of the power supply and the length of the lead. Besides, the current electro-acupuncture therapeutic apparatus causes inconvenience for carrying by the user due to the influence of the power supply, and cannot treat the disease at any time and any place.

Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and effects of the invention, but the present invention is not limited thereto.

The invention provides an electric acupuncture instrument which can solve the problem that the electric acupuncture instrument in the prior art interrupts treatment due to power consumption or restricts the action range of a user due to the influence of the length of a power line when the electric acupuncture instrument supplies power through a battery or an external power supply.

Fig. 1 shows an electric acupuncture apparatus provided in an embodiment of the present invention, including: the nano generator comprises a nano generator 1, a first electric needle 2 electrically connected with a first output end of the nano generator 1, and a second electric needle 3 electrically connected with a second output end of the nano generator, wherein the nano generator 1 is used for converting mechanical energy into electric energy and providing current for the first electric needle 2 and the second electric needle 3; the first electric needle 2 and the second electric needle 3 are used for being placed at the acupuncture points of the human body for acupuncture.

When the user uses the electro-acupuncture apparatus, first, the first electro-needle 2 and the second electro-needle 3 are respectively contacted with two acupuncture points of the epidermis of the human body according to the requirements of the disease. Then, the user starts to squeeze the nano-generator 1 of the electrical acupuncture apparatus, and the nano-generator 1 is deformed due to the squeezing, so that the squeezed mechanical energy is converted into electrical energy, and current is supplied to the first electrical needle and the second electrical needle, and thus, two acupuncture points in contact with the electrical needles have the feeling of electrical stimulation, thereby achieving the effect of dual therapy of acupuncture and electrical stimulation. In the above process, the positional relationship between the electric acupuncture apparatus and the human body can be seen with reference to FIG. 2.

The structure and operation of the nano-generator will be described in detail below.

A first configuration of the nanogenerator is shown in fig. 3a and 3 b. Fig. 3a and 3b show a schematic perspective structure and a schematic cross-sectional structure of a first structure of a nanogenerator, respectively. The nano-generator includes: a first electrode 11, a first polymer insulating layer 12, and a second electrode 13 are sequentially stacked. Specifically, the first electrode 11 is disposed on a first side surface of the first high molecular polymer insulating layer 12; and the second side surface of the first high molecular polymer insulating layer 12 rubs in contact with the surface of the second electrode 13 and induces charges at the second electrode and the first electrode. Therefore, two faces of the first polymer insulating layer and the second electrode which are oppositely arranged are used as friction interfaces of the nano-generator, and the first electrode and the second electrode can also be respectively called as a first output end and a second output end of the nano-generator.

In order to improve the power generation capability of the nano-generator, a micro-nano structure 20 is further disposed on the second side surface (i.e., the surface opposite to the second electrode 13) of the first high molecular polymer insulating layer 12. Therefore, when the nano-generator is pressed, the opposite surfaces of the first polymer insulating layer 12 and the second electrode 13 can be better rubbed in contact with each other, and more charges are induced at the first electrode 11 and the second electrode 13. Since the second electrode is mainly used for rubbing with the first polymer insulating layer, the second electrode may also be referred to as a rubbing electrode.

The micro-nano structure 20 may specifically adopt the following two possible implementation manners: in a first mode, the micro-nano structure is a micro-scale or nano-scale very small concave-convex structure. The concave-convex structure can increase the frictional resistance and improve the power generation efficiency. The concave-convex structure can be directly formed during the preparation of the film, and an irregular concave-convex structure can also be formed on the surface of the first high polymer insulating layer by using a polishing method. Specifically, the concave-convex structure may be a concave-convex structure in a shape of a semicircle, a stripe, a cube, a quadrangular pyramid, a cylinder, or the like. The second mode is that the micro-nano structure is a nano-scale porous structure, the material used for the first high molecular polymer insulating layer is preferably polyvinylidene fluoride (PVDF), the thickness of the material is 0.5-1.2mm (preferably 1.0 mm), and a plurality of nano holes are arranged on the surface of the material opposite to the second electrode. Wherein, the size of each nanopore, i.e. the width and the depth, can be selected according to the needs of the application, and the preferred size of the nanopore is as follows: the width is 10-100nm and the depth is 4-50 μm. The number of the nano-holes can be adjusted according to the required output current value and voltage value, and the nano-holes are preferably uniformly distributed with the hole spacing of 2-30 μm, and more preferably uniformly distributed with the average hole spacing of 9 μm.

The operation principle of the nano-generator is described in detail below. When each layer of the nano generator bends downwards, the second electrode in the nano generator and the surface of the first high polymer insulating layer rub with each other to generate static charges, and the generation of the static charges can change the capacitance between the first electrode and the second electrode, so that a potential difference occurs between the first electrode and the second electrode. Meanwhile, the first electrode is connected with the first electric needle as the first output end of the nanometer generator, the second electrode is connected with the second electric needle as the second output end of the nanometer generator, the first electric needle and the second electric needle are respectively contacted with different acupuncture points of the epidermis of a human body, and the human body can conduct electricity as a conductor, so that the two output ends of the nanometer generator are communicated with each other equivalently by an external circuit (namely a current loop formed by the electric needle and the human body), and when an electric potential difference occurs between the first electrode and the second electrode, free electrons respectively flow from the side with low electric potential to the side with high electric potential through the first electrode and the second electrode, so that current is formed in the external circuit, and electric stimulation is generated on acupuncture points of the human body. In addition, when the layers of the nano-generator are restored to the original state, the internal potential formed between the first electrode and the second electrode disappears, and then the balanced first electrode and the balanced second electrode generate reverse potential difference again, so that the free electrons form reverse current through an external circuit. By repeated rubbing and recovery, a periodic alternating current signal can be formed in the external circuit.

According to the research of the inventor, the metal is rubbed with the high molecular polymer, and the metal is easier to lose electrons, so that the energy output can be improved by rubbing the metal electrode with the high molecular polymer. Accordingly, in the nanogenerator shown in fig. 3a and 3b, the second electrode is required to be a friction electrode (i.e., metal) to rub against the first polymer insulating layer, so that the material of the second electrode can be selected from metals or alloys, wherein the metal can be gold, silver, platinum, palladium, aluminum, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten or vanadium; the alloy may be an aluminum alloy, a titanium alloy, a magnesium alloy, a beryllium alloy, a copper alloy, a zinc alloy, a manganese alloy, a nickel alloy, a lead alloy, a tin alloy, a cadmium alloy, a bismuth alloy, an indium alloy, a gallium alloy, a tungsten alloy, a molybdenum alloy, a niobium alloy, or a tantalum alloy. The first electrode does not need to be rubbed, so other materials capable of manufacturing the electrode can be applied besides the materials of the second electrode listed above, that is, the first electrode can be selected from metals or alloys, wherein the metals can be gold, silver, platinum, palladium, aluminum, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten or vanadium; the alloy can be aluminum alloy, titanium alloy, magnesium alloy, beryllium alloy, copper alloy, zinc alloy, manganese alloy, nickel alloy, lead alloy, tin alloy, cadmium alloy, bismuth alloy, indium alloy, gallium alloy, tungsten alloy, molybdenum alloy, niobium alloy or tantalum alloy, and can also be selected from non-metallic materials such as indium tin oxide, graphene, silver nanowire films and the like.

It can be seen that the nanogenerator shown in fig. 3a and 3b generates an electric signal mainly by friction between metal (second electrode) and polymer (first polymer insulating layer), and generates voltage or current by forming an induced electric field between the second electrode and the first polymer insulating layer mainly by utilizing the characteristic that metal easily loses electrons.

A second configuration of the nanogenerator is shown in fig. 4a and 4 b. Fig. 4a and 4b show a schematic perspective structure and a schematic cross-sectional structure of a second structure of the nanogenerator, respectively. The nano-generator includes: the first electrode 11, the first polymer insulating layer 12, the second polymer insulating layer 14, and the second electrode 13 are stacked in this order. Specifically, the first electrode 11 is provided on a first side surface of the first high molecular polymer insulating layer 12; the second electrode 13 is arranged on the first side surface of the second high molecular polymer insulating layer 14; the second side surface of the first polymer insulating layer 12 and the second side surface of the second polymer insulating layer 14 are in contact friction and induce charges at the first electrode and the second electrode, so that two surfaces of the first polymer insulating layer and the second polymer insulating layer which are oppositely arranged are used as friction interfaces of the nano-generator, and the first electrode and the second electrode can also be respectively called as a first output end and a second output end of the nano-generator.

In order to improve the power generation capacity of the nano generator, a micro-nano structure 20 is arranged on at least one of two surfaces of the first high molecular polymer insulating layer 12 and the second high molecular polymer insulating layer 14 which are oppositely arranged. Therefore, when the nano-generator is pressed, the opposite surfaces of the first polymer insulating layer 12 and the second polymer insulating layer 14 can be better rubbed in contact with each other, and more charges are induced at the first electrode 11 and the second electrode 13. The micro-nano structure can refer to the description above, and is not repeated herein.

The operation principle of the nanogenerator shown in fig. 4a and 4b is similar to that of the nanogenerator shown in fig. 3a and 3 b. The only difference is that when the layers of the nanogenerator shown in fig. 4a and 4b are bent, static charges are generated by the mutual friction between the surfaces of the first high polymer insulating layer and the second high polymer insulating layer. Therefore, the operation principle of the nanogenerator shown in fig. 4a and 4b will not be described in detail herein.

The nanogenerator shown in fig. 4a and 4b mainly generates an electrical signal by friction between a polymer (a first high polymer insulating layer) and a polymer (a second high polymer insulating layer).

In the structure shown in fig. 4a and 4b, the material used for the first electrode and the second electrode may be indium tin oxide, graphene, silver nanowire film, metal or alloy, wherein the metal may be gold, silver, platinum, palladium, aluminum, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten or vanadium; the alloy may be an aluminum alloy, a titanium alloy, a magnesium alloy, a beryllium alloy, a copper alloy, a zinc alloy, a manganese alloy, a nickel alloy, a lead alloy, a tin alloy, a cadmium alloy, a bismuth alloy, an indium alloy, a gallium alloy, a tungsten alloy, a molybdenum alloy, a niobium alloy, or a tantalum alloy. It can be seen that, since the second electrode does not need to be a rubbing electrode in the structure shown in fig. 4a and 4b, the second electrode can also be implemented by using a non-metal material.

In the above two structures, the first polymer insulating layer and the second polymer insulating layer may be respectively selected from a polyimide film, an aniline formaldehyde resin film, a polyoxymethylene film, an ethylcellulose film, a polyamide film, a melamine formaldehyde film, a polyethylene glycol succinate film, a cellulose acetate film, a polyethylene glycol adipate film, a polydiallyl phthalate film, a fiber (regenerated) sponge film, a polyurethane elastomer film, a styrene-propylene copolymer film, a styrene-butadiene copolymer film, a rayon film, a polymethyl film, a methacrylate film, a polyvinyl alcohol film, a polyester film, a polyisobutylene film, a polyurethane flexible sponge film, a polyethylene terephthalate film, a polyvinyl butyral film, a polyvinyl acetate film, a polyethylene adipate film, a polydiallyl phthalate film, a cellulose (regenerated) sponge film, a polyurethane elastomer film, a styrene-propylene copolymer film, a styrene-, One of a formaldehyde phenol film, a chloroprene rubber film, a butadiene-propylene copolymer film, a natural rubber film, a polyacrylonitrile film, an acrylonitrile-vinyl chloride film and a polyethylene propylene carbonate film. In principle, the first polymer insulating layer and the second polymer insulating layer may be made of the same material or different materials. However, if the two polymer insulating layers are made of the same material, the amount of triboelectric charge is small. Therefore, the first polymer insulating layer and the second polymer insulating layer are preferably made of different materials.

In addition to the above two structures, the nanogenerator may be implemented using a third structure, as shown in fig. 5a and 5 b. Fig. 5a and 5b show a schematic perspective structure and a schematic cross-sectional structure of a third structure of the nanogenerator, respectively. As can be seen from the figure, the third structure adds an intervening thin film layer to the second structure, namely: the nano-generator with the third structure comprises a first electrode 11, a first high molecular polymer insulating layer 12, an intermediate thin film layer 10, a second high molecular polymer insulating layer 14 and a second electrode 13 which are sequentially stacked. Specifically, the first electrode 11 is disposed on a first side surface of the first high molecular polymer insulating layer 12; the second electrode 13 is disposed on a first side surface of the second high molecular polymer insulating layer 14, and the intervening thin film layer 10 is disposed between a second side surface of the first high molecular polymer insulating layer 12 and a second side surface of the second high molecular polymer insulating layer 14. Wherein, be equipped with micro-nano structure 20 on at least one of two faces that thin layer and first high molecular polymer insulating layer set up relatively between and/or be equipped with micro-nano structure 20 on at least one of two faces that thin layer and second high molecular polymer insulating layer set up relatively between, can refer to above description about micro-nano structure 20's specific setting mode, and it is no longer repeated here. Correspondingly, two surfaces of the intermediate thin film layer and the first high polymer insulating layer which are oppositely arranged and/or two surfaces of the intermediate thin film layer and the second high polymer insulating layer which are oppositely arranged are used as friction interfaces of the nano-generator.

Preferably, the first side surface of the intermediate thin film layer 10 is disposed on the second side surface of the second polymer insulation layer 14, and the second side surface of the intermediate thin film layer 10 is in contact with the second side surface of the first polymer insulation layer 12, at this time, since the intermediate thin film layer and the second polymer insulation layer are relatively fixed, only two surfaces of the intermediate thin film layer and the first polymer insulation layer which are relatively disposed serve as a friction interface of the nanogenerator. Thus, when the nanogenerator is compressed, the second side surface of the first high polymer insulating layer rubs against the second side surface of the intervening thin film layer and induces charges at the first and second electrodes. It can be seen that the first and second electrodes serve as two output terminals of the nanogenerator, respectively.

In the nanogenerator shown in fig. 5a and 5b, the first side surface (i.e., the side not provided with the micro-nano structure) of the intermediate film layer 10 is fixed on the second side surface of the second polymer insulating layer 14, and the fixing method may be that a thin uncured polymer insulating layer is used as an adhesive layer, and after curing, the intermediate film layer 10 is firmly fixed on the second polymer insulating layer 14. One side of the intermediate film layer 10 provided with the micro-nano structure is in surface contact with the second side of the first high polymer insulating layer 12, and a friction interface is formed between the micro-nano structure and the first high polymer insulating layer.

The material of the nanogenerator shown in fig. 5a and 5b may be selected with reference to the material of the nanogenerator having the second structure. The intermediate film layer may be selected from any one of transparent high polymer polyethylene terephthalate (PET), Polydimethylsiloxane (PDMS), Polystyrene (PS), polymethyl methacrylate (PMMA), Polycarbonate (PC), and Liquid Crystal Polymer (LCP). The material of the first high molecular polymer insulating layer and the material of the second high molecular polymer insulating layer are preferably transparent high polymer polyethylene terephthalate (PET); among them, the material of the intermediate thin film layer is preferably Polydimethylsiloxane (PDMS). The first polymer insulating layer, the second polymer insulating layer and the intermediate thin film layer may be made of the same material or different materials. However, if the three polymer insulating layers are made of the same material, the amount of charge for triboelectrification is small, so that in order to improve the friction effect, the material of the intermediate thin film layer is different from the material of the first polymer insulating layer and the material of the second polymer insulating layer, and the material of the first polymer insulating layer and the material of the second polymer insulating layer are preferably the same, so that the material types can be reduced, and the manufacturing of the invention is more convenient.

In the implementation shown in fig. 5a and 5b, the intermediate thin film layer 10 is a polymer film and thus is substantially similar to the implementation shown in fig. 4a and 4b, yet generates electricity by friction between the polymer (intermediate thin film layer 10) and the polymer (first high molecular polymer insulating layer). Wherein the intermediate film is easy to prepare and has stable performance.

In addition, the nanogenerator can also be realized by adopting a fourth structure, as shown in fig. 6a and 6b, comprising a first electrode 11, a first high polymer insulating layer 12, an intermediate electrode layer 80, a second high polymer insulating layer 14 and a second electrode 13 which are sequentially stacked; wherein, the first electrode 11 is arranged on the first side surface of the first high molecular polymer insulating layer 12; the second electrode 13 is disposed on the first side surface of the second high molecular polymer insulating layer 14, and the intermediate electrode layer 80 is disposed between the second side surface of the first high molecular polymer insulating layer 12 and the second side surface of the second high molecular polymer insulating layer 14. Wherein, at least one of the surface of the first polymer insulating layer 12 opposite to the intermediate electrode layer 80 and the surface of the intermediate electrode layer 80 opposite to the first polymer insulating layer 12 is provided with a micro-nano structure (not shown); a micro-nano structure (not shown) is provided on at least one of the surface of the second polymer insulating layer 14 facing the intermediate electrode layer 80 and the surface of the intermediate electrode layer 80 facing the second polymer insulating layer 14. In this way, static charge is generated by friction between the intermediate electrode layer 80 and the first and second polymer insulating layers, so that a potential difference is generated between the intermediate electrode layer 80 and the first and second electrodes, at this time, two surfaces of the first polymer insulating layer and the intermediate electrode layer which are arranged oppositely are used as one friction interface of the nanogenerator, two surfaces of the second polymer insulating layer and the intermediate electrode layer which are arranged oppositely are used as the other friction interface of the nanogenerator, and the first and second electrodes are connected in series to form one output end of the nanogenerator; the intermediate electrode layer is the other output end of the nano-generator.

In the structure shown in fig. 6a and 6b, the materials of the first polymer insulating layer, the second polymer insulating layer, the first electrode, and the second electrode may be selected with reference to the nanogenerator having the second structure. The intermediate electrode layer 80 may be selected from conductive thin films, conductive polymers, and metal materials, the metal materials include pure metals and alloys, the pure metals are selected from gold, silver, platinum, palladium, aluminum, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten, vanadium, etc., the alloys may be selected from light alloys (aluminum alloys, titanium alloys, magnesium alloys, beryllium alloys, etc.), heavy non-ferrous alloys (copper alloys, zinc alloys, manganese alloys, nickel alloys, etc.), low melting point alloys (lead, tin, cadmium, bismuth, indium, gallium and their alloys), refractory alloys (tungsten alloys, molybdenum alloys, niobium alloys, tantalum alloys, etc.). The thickness of the intermediate electrode layer 80 is preferably 100 μm to 500. mu.m, more preferably 200. mu.m.

The nano-generators described above are all triboelectric nano-generators, and in practical cases, the nano-generators may also be piezoelectric nano-generators made of piezoelectric materials (e.g. zinc oxide nanowires).

The nano generator with the structure can generate pulse current when being extruded, the pulse current is alternating current, the requirement of electric acupuncture treatment is just met, and the conversion from direct current to alternating current is not needed, so that the structure of the electric acupuncture instrument is extremely simple and the use is convenient.

Moreover, the magnitude of the current carried by the electric needle of the electric acupuncture apparatus in the embodiment of the invention depends on the pressing degree of the nano generator, so that a user can adjust the pressing degree of the nano generator according to needs to change the magnitude of the current. For example, the intensity of the current may be increased by increasing the pressing force on the nanogenerator, or the frequency of the current may be increased by increasing the pressing frequency on the nanogenerator, whereby the therapeutic effect can be further improved.

In addition, in order to increase the power generation amount, the nano-generator in the above electric acupuncture apparatus may be further provided as a plurality of nano-generators. When the number of the nano-generators is multiple, the multiple nano-generators can be connected in series or in parallel. When the nanometer generators are connected in parallel, the output intensity of current can be improved, and when the nanometer generators are connected in series, the output magnitude of the voltage can be improved, so that the problem that the current or the voltage output by a single nanometer generator cannot meet the electric acupuncture and moxibustion requirements can be solved. In order to obtain the above advantages at the same time, it is also conceivable to connect a part of the nanogenerators in parallel and another part of the nanogenerators in series. Moreover, in order to further adjust the voltage output by the nano-generator to meet the precise requirements of users, the electric acupuncture apparatus may further include a transformer, which may be either a step-up transformer or a step-down transformer. The transformer is respectively connected with the first output end and the second output end of the nano generator, so that the first electric needle is electrically connected with the first output end of the nano generator through the transformer, and the second electric needle is electrically connected with the second output end of the nano generator through the transformer.

The first electric needles and the second electric needles of the electric acupuncture instrument according to the embodiment of the present invention will be described in detail. Two kinds of electric needles are needed to be arranged, not only for stimulating two acupuncture points at the same time, but also for forming a complete current loop with the human body. Because the electric acupuncture instrument of the invention generates alternating current, when the first electric needle is positively charged, the second electric needle is negatively charged; conversely, when the first electrical pin is negatively charged, the second electrical pin is positively charged.

A first configuration of the first or second electrical needle is shown in fig. 7 a. This electricity needle includes: a conductive pin 21, and a fixing device 22 fixed at the middle part of the conductive pin 21; the fixing device 22 is used for fixing the position of the conductive needle 21, one end of the conductive needle 21 is used for being inserted into a human body acupoint, and the other end of the conductive needle 21 is used for being electrically connected with the output end of the nano-generator through a conductive clip (not shown). When in specific use, one end (usually a relatively sharp end) of the conductive needle 21 is inserted into a human acupuncture point, and the specific insertion depth can be adjusted according to the needs of the acupuncture point; then, the fixing device 22 is used to further fix the position of the conductive pin to prevent the conductive pin from coming off, specifically, the fixing device 22 may be implemented by a flexible insulating patch or other insulating device capable of fixing; finally, the other end of the conductive pin 21 is clamped by one end of a conductive clamp, and the other end of the conductive clamp is connected to one output end of the nano-generator through a wire. In this way, the first electric needle and the second electric needle are electrically connected with the first output end and the second output end of the nano generator respectively. The electrical needle of the first structure can be inserted into a human body to achieve deep electrical stimulation.

A second configuration of the first or second electrical needle is shown in fig. 7 b. This electricity needle includes: the nano generator comprises a conductive patch 31 and a conductor 32 fixedly connected with the conductive patch 31, wherein the conductive patch 31 is used for being placed at a human body acupuncture point, and the conductor 32 is used for being electrically connected with the output end of the nano generator through a conductive clip. When in specific use, one side of the conductive patch 31, which is not provided with the conductor 32, is attached to the acupuncture point of the human body, the size of the conductive patch can be set according to the size of the acupuncture point of the human body, and the conductive patch can also play a role of fixing the position; the conductor 32 is then clamped at one end by a conductive clamp, the other end of which is connected to one output of the nanogenerator by a wire. In this way, the first electric needle and the second electric needle are electrically connected with the first output end and the second output end of the nano generator respectively. The electric acupuncture needle with the second structure does not penetrate into a human body, and only carries out electric acupuncture and moxibustion on the surface layer of the skin, so that the electric acupuncture needle can meet the requirements of patients with needle sickness and reduce the pain of penetration.

A third configuration of the first or second electrical needle is shown in fig. 7 c. This electricity needle includes: a needle structure 41 capable of conducting electricity, and a wire 42 wrapped with an insulating layer 40; the needle-shaped structure 41 is internally provided with a cavity, the wire 42 is embedded in the cavity, one end of the wire 42 is electrically connected with the output end of the nano generator, the other end of the wire 42 is electrically contacted with the needle point part of the needle-shaped structure 41, and the needle point part is used for being inserted into a human body acupuncture point. The needle structure may preferably be a conical needle structure to facilitate penetration into the human body. When in specific use, the needle point part of the needle-shaped structure of the electric needle is directly punctured into an acupuncture point. Compared with the electric needles with the first two structures, the electric needle with the third structure has the following advantages: the current output from the nano generator is directly sent to the needle point part inside the needle-shaped structure 41 through the conducting wire 42 wrapped with the insulating layer, so that the strongest current at the needle point part can be ensured, namely the most obvious electric stimulation effect is achieved, thereby directly stimulating acupuncture points under the epidermis of a human body and achieving more effective micro-current treatment effect. Moreover, the electric acupuncture needle shown in fig. 7c can further prevent the waste of electric energy caused by the discharge of the portion of the electrode which is not in direct contact with the acupuncture point of the human body, compared with the electric acupuncture needle shown in fig. 7 a. Moreover, since the electrical signal usually generates a certain loss during transmission, if the electrical needle shown in fig. 7a is used, the electrical signal will be attenuated when the electrical signal is transmitted from the electrical needle portion clamped by the conductive clip to the electrical needle portion inserted into the human body, thereby weakening the stimulation of the electrical signal at the acupuncture point of the human body. However, with the electric needle shown in fig. 7c, since the electric signal can be directly transmitted to the portion where the electric needle contacts the acupuncture point of the human body, the stimulation of the electric signal to the acupuncture point can be enhanced, and the acupuncture effect can be further improved.

In actual conditions, the electric needle with any structure can be flexibly selected according to needs. In addition, in order to meet the requirement of a user for simultaneously stimulating a plurality of acupuncture points, the number of the first electric needles and the number of the second electric needles in the electric acupuncture apparatus according to the embodiment of the present invention may be respectively plural. When the number of the first electric needles and the number of the second electric needles are respectively multiple, the number of the first electric needles and the number of the second electric needles can be equal, so that each first electric needle is provided with one second electric needle; alternatively, the number of the first electric needles and the number of the second electric needles may be different, for example, the number of the first electric needles is greater than that of the second electric needles, so that one first electric needle and a plurality of second electric needles can respectively form a plurality of different current loops, thereby stimulating a plurality of acupuncture points simultaneously. In order to meet the requirements of different users, the electric acupuncture apparatus can be respectively matched with the electric acupuncture needles with the structures shown in fig. 7a to 7c, so that the use of the electric acupuncture apparatus is convenient for the users. In addition, in addition to the above-described case of simultaneously stimulating two or more acupuncture points, sometimes a user may need to individually stimulate one acupuncture point, in which case one electrical needle is required to carry current to form electrical stimulation to a human body, and the other electrical needle is grounded as an unrelated electrode to form electrical stimulation to the human body. For example, in case that the first electrical acupuncture stimulates the human body and the second electrical acupuncture does not stimulate the human body as an indifferent electrode, the first electrical acupuncture is firstly inserted into an acupuncture point (such as a jumping point of a lower limb) through which a main nerve trunk passes, and then the first electrical acupuncture is electrically connected to one output terminal of a nano-generator of the electrical acupuncture; then, gauze soaked by saline water is wrapped on the second electric acupuncture, and the second electric acupuncture is taken as an irrelevant electrode to be fixed on the skin on the same side with the channels and collaterals punctured by the first electric acupuncture, so that the second electric acupuncture is grounded through the human body. Thus, the purpose that only the first electric needle stimulates the human body and the second electric needle does not stimulate the human body can be realized. Usually, the same pair of electric needles are connected to the same side of the body, especially when the electric needles are used on the acupoints of the chest and back, it is not possible to connect the two electric needles across the two sides of the body to avoid the current loop passing through the heart. When the power is on, the current intensity is gradually increased so as not to cause sudden stimulation to the patient.

The conductive parts in the electric pins, such as conductive patches or conductive pins, can be made of metal or alloy. The material of the first electrode and the material of the second electrode may be the same or different.

In addition, in the present embodiment, in order to facilitate the user's use, the nano-generator in the electric acupuncture apparatus may be made into a cylindrical structure as shown in fig. 8a, or a balloon type structure as shown in fig. 8b, so that the user can hold the apparatus in his hand conveniently to pat or squeeze the apparatus, thereby completing the treatment. Specifically, when a cylindrical or air-bag type nano-generator is manufactured, the nano-generator can be directly used as a cylindrical or air-bag type nano-generator. For example, each layer (including electrodes and high molecular polymers) in the nanogenerator is formed in a circular shape, thereby forming a cylindrical nanogenerator. Or, two parts which rub each other in the nano generator are respectively made into an arch structure which is arched outwards, so that the two rubbing surfaces can automatically bounce without being stressed, and the air bag type nano generator is manufactured. Specifically, the arch structure can be manufactured by using an adhesive tape bonding or heat sealing method, and the specific process can be as follows: aligning the cross sections of the two contact surfaces on one side, sealing the two contact surfaces by using an adhesive tape or a heat sealing method, then arching the two contact surfaces, and aligning the cross sections of the two contact surfaces on the other side, and then adhering the two contact surfaces in the same way. For example, taking fig. 3a and 3b as an example, in a state of not being pressed, it is necessary to arch the second electrode to the upper side, arch the first high molecular polymer insulating layer together with the first electrode to the lower side, so that an elliptical gap is formed between the second electrode and the first high molecular polymer insulating layer to form a gas cell structure, thereby making the nano-generator mechanism as a gas cell type. Taking fig. 4a and 4b as an example, in a non-compressed state, it is necessary to arch the second electrode together with the second high polymer insulating layer to the upper side, and arch the first electrode together with the first high polymer insulating layer to the lower side, so that an elliptical gap is formed between the first high polymer insulating layer and the second high polymer insulating layer to form the air bag structure. Taking fig. 5a and 5b as an example, in an uncompressed state, it is necessary to arch the second electrode together with the second polymer insulating layer and the intermediate film layer to the lower side, and the first electrode together with the first polymer insulating layer to the upper side, so that an oval-like gap is formed between the first polymer insulating layer and the intermediate film layer to form the air cell structure. Taking fig. 6a and 6b as an example, in a non-pressed state, the second electrode and the second polymer insulating layer need to be arched downward, and the first electrode and the first polymer insulating layer need to be arched upward, so that gaps are formed between the intermediate electrode layer and the first polymer insulating layer, and between the intermediate electrode layer and the second polymer insulating layer, respectively, to form the air bag structure. When the air bag structure is not extruded, the two friction interfaces are separated from each other, and when the air bag structure is extruded, the two friction interfaces naturally contact and rub with each other due to the action of external force. The friction interface of the nano generator is respectively arranged into an arch structure, so that a user can conveniently hold or flap the nano generator, the power generation efficiency can be improved, because according to the working principle of the nano generator, two friction interfaces need to continuously contact friction and separation in the working process of the generator, and the generator cannot have good output performance when being in a contact state or a separation state all the time, and therefore, the arched nano generator can further improve the friction effect.

Besides the above mode, a cylindrical or air bag type casing can be manufactured for the nano-generator to facilitate the use of users. The outer sleeve can be made of a cloth bag or other flexible insulating materials so as to coat the nano generator. For example, the electric acupuncture apparatus in the embodiment of the present invention may further include an air bag-shaped packaging structure, and the nano-generator is packaged in the packaging structure, wherein the air bag-shaped packaging structure further includes two layers of packaging films, the two layers of packaging films are fused together to form a fused edge, and an accommodating cavity for accommodating the nano-generator is formed inside the fused edge. One or more nanogenerators can be placed in the accommodating cavity. Specifically, the encapsulating film is a thermoplastic plastic film or a multilayer composite film including a thermoplastic film. Any thermoplastic capable of melting may be used in the present invention, for example, the thermoplastic is polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyoxymethylene, polycarbonate, polyamide, acrylic, other polyolefins and copolymers thereof, polysulfone, polyphenylene oxide, chlorinated polyether, and the like. The multilayer film material is Preferably Polypropylene (PP) or Polyethylene (PE) with polyethylene terephthalate (PET) as a substrate. Preferably, in order to reduce the influence of the encapsulation on the performance of the generator to the maximum extent, the encapsulation film may be punched in advance to form a groove with a suitable size and shape, and the grooves of the two layers of encapsulation films form the accommodating cavity.

In addition, also from the viewpoint of facilitating the holding or flapping of the user, in the present invention, not only a single nanogenerator but also every adjacent two or more nanogenerators among a plurality of nanogenerators may be provided as an airbag structure. For example, when the number of the nanogenerators in the invention is plural, two or more adjacent nanogenerators may be stacked and arched outward without being pressed, respectively, to form an air bag structure between the two adjacent nanogenerators.

The nano generator-based electric acupuncture instrument has the following advantages:

firstly, the nano generator is adopted to carry out the electro-acupuncture treatment, the pulse electricity for the treatment is generated by pressing the nano generator to deform, so the strength and the frequency of the pulse electricity can be controlled and adjusted through the mechanical deformation of the nano generator, the strength and the frequency of the pulse electricity are required by the treatment, and the treatment effect can be improved.

Secondly, the voltage and the current generated by the nanometer friction generator are pulse waves, which just meet the treatment requirements of the electric acupuncture instrument, and the conversion from direct current to alternating current is not needed, so that the structure of the electric acupuncture instrument is extremely simple and the use is convenient.

And thirdly, as long as the user presses the nano generator, the electric quantity can be generated to provide electric energy for the electric acupuncture instrument, so that the problem that the electric quantity of the battery cannot be supplied after the electric quantity of the battery is used up is solved, the trouble caused by replacing the battery or charging the rechargeable battery is also saved, and the resources are greatly saved. The electric acupuncture instrument can be normally used by a user in any place without the limitation of the length of a power line, so that the electric acupuncture instrument is convenient to carry by the user.

In addition, the nano generator is adopted by the nano generator to carry out the electro-acupuncture treatment, and the nano generator generates electric pulses by external extrusion, friction and vibration, so that the electro-acupuncture instrument is less interfered by the outside, has low requirement on the outside environment, and has safer and more reliable performance.
