[0040] Specifically, the needle fixing rotating plate 2 includes a rotating ring 21 and a fixed ring 22 connected as a whole from top to bottom. The rotating ring 21 is in a circular ring shape. A plurality of friction teeth 211 are provided on the outer side of the rotating ring 21 for manually rotating and driving the rotating ring 21. The top plane of the rotating ring 21 has a plurality of second positioning lines 212 evenly distributed along the circumference and corresponding to the positions of the plurality of first positioning lines 112 respectively, which are used for precise rotation positioning of the micro needle 3. The top plane of the rotating ring 21 has a plurality of impact holes 213 evenly distributed along the circumference and corresponding to the positions of the plurality of second positioning lines 212 respectively. The opening diameter of the impact hole 213 is slightly smaller than the diameter of the needle holder 31. , which is a force application channel for the external mechanical structure; the inner side surface of the rotating ring 21 has a plurality of circumferentially evenly distributed snap-in grooves 214 and respectively correspond to the positions of the plurality of second positioning lines 212, and is slightly raised in annular shape; the side surface of the boss has a positioning groove 114 corresponding to the position of the snap-in groove 214, and a positioning member 7 is installed in the positioning groove 114 for precise rotation positioning of the micro needle 3; the fixed ring 22 is embedded in the rotating groove 111, and the bottom plane of the fixed ring 22 has a plurality of needle bins 221 evenly distributed along the circumferential direction and respectively correspond to and are connected to the positions of the plurality of impact holes 213, and the plurality of micro needles 3 are respectively installed in the plurality of needle bins 221.

[0041] Specifically, the needle fixing rotating plate 2 is formed by integrally processing with insulating materials.

[0042] Of course, the present invention can arrange more micro-needles 3 by increasing the diameter of the needle bin 221 or reducing the angle between the micro-needles 3 to meet the use needs of a large number of needles. Therefore, the number of micro-needles 3 on a single needle bin can be flexibly adjusted according to actual needs.

[0043] Specifically, the needle holder 31 is cylindrical, the diameter of the needle rod 32 is smaller than that of the needle holder 31 , and the top of the needle rod 32 is a sharp needle head. External force acts on the side of the needle holder 31 away from the needle rod 32 , and can pierce the needle head 33 into the acupuncture point.

[0044] Specifically, the micro needle 3 is made of stainless steel as a whole, which is easy to disinfect, has high strength, strong toughness, is conductive and has a good insertion effect. The micro needle 3 can penetrate into the acupuncture points through an external mechanical structure, solving the problem that existing large-size acupuncture needles can only be inserted into the acupuncture points manually by professional doctors, and can prevent falling off, reducing the probability of infection caused by acupuncture.

[0045] Specifically, the needle ejection mechanism 4 includes a pressing member 41, a needle ejection assembly 42 and a reset spring 43. The pressing member 41, the electric stimulation generating mechanism 51 of the electric stimulation mechanism 5, the needle ejection assembly 42 and the reset spring 43 are connected as a whole from top to bottom. The electric stimulation generating mechanism 51 and the reset spring 43 are located in the electric stimulation mechanism placement groove 121, and the bottom end surface of the reset spring 43 abuts against the top plane of the boss; the pressing member 41 extends out of the top end of the electric stimulation mechanism placement groove 121; the needle ejection assembly 42 extends out of the window 122 and corresponds to the position of the impact hole 213. Pressing the pressing member 41 downward can realize the ejection of the micro needle 3 and generate voltage at the same time as the electric stimulation mechanism 5. The pressing member 41 includes a pressing head 411 in contact with the force-applying finger and a pressing rod 412 that transmits force. The cross-sectional area of ​​the pressing rod 412 is smaller than that of the pressing head 411.

[0046] Specifically, the electrical stimulation mechanism 5 also includes an external wire 52 and a negative wire 53. The electrical stimulation generating mechanism 51 is electrically connected to the needle assembly 42 via the external wire 52; the top end of the negative wire 53 is connected to the electrical stimulation generating mechanism 51, and the bottom end of the negative wire 53 passes through the reset spring 43 and extends out of the wire through hole 113.

[0047] Specifically, the needle ejection assembly 42 includes a guide rod 421, a conductive rod 422 and a needle ejection rod 423. The guide rod 421 is made of insulating material, and one end of the guide rod 421 has an extension hole 4211 for the negative electrode wire to pass through; the conductive rod 422 is embedded and fixed in the guide rod 421, and is used to conduct the current of the electric stimulation mechanism 5, and is made of conductive material; the needle ejection rod 423 is located at the end of the guide rod 421 away from the extension hole 4211 and is connected to the conductive rod 422. The needle ejection rod 423 corresponds to the position of the impact hole 213, and is used to eject the micro needle 3 and conduct electricity at the same time. When the second positioning line 212 coincides with the first positioning line 112, the needle ejection rod 423 is located directly above the center of the micro needle 3, and the micro needle 3 can be ejected out of the needle hole 1111.

[0048] In this embodiment, the acupuncture device can store multiple micro needles 3 at one time, and adopts the ejection method of the reset spring 43 and the self-positioning method of the positioning groove 214 and the positioning groove 114, so that the needles can be ejected continuously during treatment, ensuring the convenience of the entire equipment and the hygiene of the needles in special working environments. The method of continuously ejecting needles is specifically as follows: the needle fixing rotating plate 2 fixed with multiple micro needles 3 is placed on the base 11, and can be rotated 360 degrees around the central axis of the base 11, and the micro needle 3 can be pushed out by the external force applied by the needle rod 423. After the ejection of the micro needle 3 is completed, the compressed reset spring 43 will return the needle rod 423 to its original position, and the needle fixing rotating plate 2 is rotated again so that the next micro needle 3 is aligned with the needle rod 423, and the ejection of the micro needle 3 in the next use cycle can be completed.

[0049] Specifically, the electric stimulation generating mechanism 51 includes a shell 511 and a force storage spring 512, a knocking hammer 513, an electric stimulation reset spring 514, a piezoelectric ceramic protection cap 515, a first piezoelectric ceramic 516, a phosphor bronze sheet 517 and a second piezoelectric ceramic 518, which are connected in sequence from top to bottom inside the shell 511. The pressing piece 41 is fixedly connected to the force storage spring 512 at its bottom; the phosphor bronze sheet 517 is connected to the external wire 52 through a wire 519, a metal cap 54 is fixed to the bottom of the shell 511, and the guide rod 421 is fixed on the metal cap 54; the top of the negative electrode wire 53 is connected to the negative electrode of the second piezoelectric ceramic 518.

[0050] The working principle of the electric stimulation mechanism 5 is as follows: by pressing the pressing piece 41, the electric stimulation mechanism 5 can convert mechanical energy into electrical energy. Specifically, when the pressing piece 41 is pressed downward, the force storage spring 512 increases the elastic potential energy while pushing the knocking hammer 513 downward. The electric stimulation reset spring 514 directly below the knocking hammer 513 increases the elastic potential energy and squeezes the piezoelectric ceramic protection cap 515. The piezoelectric ceramic protection cap 515 transmits the squeezing force to two piezoelectric ceramics with the same poles facing each other, and the piezoelectric ceramics are electrostatically polarized. When the squeezing force reaches a certain level, the piezoelectric ceramics emit a radio frequency current. At this time, the two piezoelectric ceramics The phosphor copper sheet 517 will generate an instantaneous positive potential through the wire 519 to export it to the electrical stimulation generating mechanism 51, and conduct it to the micro needle 3 through the needle assembly 42. The negative potential is connected to the metal cap 54 through the wire 519, and contacts the human skin through the reset spring 43 and the negative wire 53. At the moment the micro needle 3 is ejected, it is energized. The instantaneous electrical stimulation technology enhances the therapeutic effect by enhancing the stimulation, and the safety of the electrical stimulation is guaranteed due to the small current (the current does not exceed the human safety range of 20-60mA, and the pulse width range is 2-50 microseconds. Studies have shown that less than 50 microseconds can easily excite thick nerve fibers).

[0051] Specifically, piezoelectric ceramics have a compact structure, small size, light weight, and their potential changes very quickly when stimulated by external stimuli. They can convert mechanical energy into electrical energy, have high working efficiency, low noise, and are not prone to medium changes. The line connection is simple and not prone to failure. The energy transfer efficiency is high and stable, and the characteristics are constant. They have high adaptability to ambient temperature and humidity and have moisture-proof and heat-resistant properties. Since piezoelectric ceramic technology is used to convert mechanical energy into electrical energy, no additional power supply is required, and in theory, unlimited power generation can be achieved, which greatly increases the feasibility of the portability of the acupuncture device of the present invention and facilitates use in special working environments.

[0052] In order to further optimize the technical solution of the present invention, a passive portable electroacupuncture device also includes a fixed block 8, which is fixed on the top of the T-shaped column 12 and is located directly above the electric stimulation mechanism placement slot 121; the fixed block 8 has a shell clamping slot 81, and the fixed block 8 is provided with a through hole 82 for the pressing piece 41 to pass through.

[0053] Specifically, the positioning member 7 includes a positioning spring 71 and a positioning ball 72 which are connected as one body. The positioning spring 71 and the positioning ball 72 are sequentially installed in the positioning groove 114 from the inside to the outside, and rotate to drive the needle to fix the rotating plate 2. When the locking groove 214 is located on the same radius line as the positioning groove 114, the positioning spring 71 releases the elastic force, and the positioning ball 72 is embedded in the locking groove 214, emitting a positioning mechanical sound, thereby realizing the mechanical positioning of the needle fixing rotating plate 2.

[0054] The working process of the present invention is as follows: the first step is to rotate the needle to fix the rotating plate 2 so that the second positioning line 212 and the first positioning line 112 are on a radius extension line, and the positioning member 7 in the positioning groove 114 just achieves mechanical positioning with the positioning groove 214; the second step is to select the acupuncture point to be acupunctured, and align and close the position of the needle hole 1111; the third step is to support the hand rest with the fingers and press the pressing member 41, and the needle assembly 42 pushes the micro needle 3 out of the needle bin 221, and at the same time the electrical stimulation generating mechanism 51 generates a pulse voltage and transmits it to the micro needle 3, realizing synchronous acupuncture and electrical stimulation. Then repeat steps 1-3.

The same or similar parts between the embodiments can be referred to each other.
