Description

Technical Field

[0001] The utility model relates to the field of electric needle connectors, in particular to a flat-push type electric needle connector. Background Art

[0002] Electroacupuncture therapy is to treat diseases by passing (sensing) a small amount of current waves of human bioelectricity through the needle after the acupuncture needle is inserted into the acupoint to obtain qi. In electroacupuncture therapy, after the needle is inserted into the patient's body, a connector is needed to connect the needle body and the electroacupuncture treatment instrument to achieve power supply. The above connector is currently commonly used as an alligator clip connected to the electroacupuncture treatment instrument. The alligator clip is usually used to clamp the tail of the acupuncture needle to connect the acupuncture needle. However, the use of an alligator clip as an electroacupuncture connector has the following problems: ① Inconvenient operation: For example, the operation needs to be very delicate, and the serrated part of the alligator clip needs to be controlled to bite the tail of the needle. If the clip is slightly bitten too deep, it will not bite the tail of the needle, which may easily cause the needle body to fall off; for another example, the clip itself is relatively small, but it is operated by two fingers, and sometimes it is difficult to control the force of the fingers to pinch it open; ② The clip has its own weight. After the needle is left in, it is easy to cause the needle body to bend and deform, and even when the acupuncture is shallow, it is easy to cause the needle body to be pulled out from the acupoint. Therefore, it is necessary to improve the existing technology and provide an electroacupuncture connector that is more convenient to operate and can reduce the effect of the connector's own weight on acupuncture of the needle body. Summary of the invention

[0003] Therefore, based on the above background, the utility model provides a push-type electroacupuncture connector, which is simple and convenient to operate. After the needle is left in place, the base shell is placed on the skin, which can reduce the pressure on the needle body caused by the connector's own weight, and avoid problems such as bending and deformation of the needle body or needle body falling out due to the connector's own weight.

[0004] The technical solution provided by the utility model is:

[0005] A flat push type electric needle connector:

[0006] The base shell comprises a sector-shaped shell head with an angle greater than 300°, wherein the shell head has a first limiting hole at a position corresponding to the center of the circle, and the first limiting hole is penetrated by a sector-shaped first needle inlet hole;

[0008] The driving mechanism drives the limit adjustment plate to rotate through the driving gear to control the opening and closing of the first needle entry hole.

[0009] Further, a handle portion extends from a position of the shell head portion directly opposite to the needle insertion hole.

[0010] Further, the driving mechanism includes an L-shaped control board which can move horizontally.

[0014] Further, a first guiding groove is provided on the shell head portion around the circumference of the first limiting hole. A first guiding limiting groove is provided on the inner wall of the first guiding groove. One end of the first guiding groove and the first guiding limiting groove penetrates the first needle insertion hole.

[0015] A first guiding block corresponding to the first guiding groove is provided at the lower part of the gear. A first guiding limiting plate corresponding to the first guiding limiting groove is provided on the side wall of the first guiding block.

[0016] Further, a second guiding groove is provided on the shell head portion, and one end of the second guiding groove penetrates the first needle insertion hole.

[0047] The gear is rotatably mounted on the base shell 100. The implementation structure of this embodiment can be seen as follows:

[0048] Specifically, as Figure 3 and Figure 4 shown, a first guiding groove 16 is provided on the circumference of the shell head 12 located at the first limiting hole 13. A first guiding and limiting groove 17 is provided on the inner wall of the first groove 16. One end of the first guiding groove 16 penetrates through the first needle insertion hole 14. A first guiding block 26 corresponding to the first guiding groove 16 is provided at the lower part of the gear 21.

The first guiding block 26 can rotate along the first guiding groove 16, and the first guiding and limiting plate 27 can rotate along the first guiding and limiting groove 17. Of course, the structure for rotatably mounting the gear on the base shell 100 is not limited to the above. For example, it can also be rotatably mounted through a bearing, which is prior art and will not be elaborated here.

[0049] A second guiding groove 15 is provided on the shell head 12. One end of the second guiding groove 15 penetrates through the first needle insertion hole 14. A second guiding block 28 corresponding to the second guiding groove 15 is provided at the lower part of the limiting and adjusting plate 24.

The third guiding block 34 can slide in the left - right direction along the third guiding groove 18, and the second guiding and limiting plate 27 can slide in the left - right direction along the second limiting and guiding groove 19. In this embodiment, the length of the third guiding groove 18 in the left - right direction is 4.0 - 5 mm.

[0051] In this embodiment, the first guiding block 26, the first guiding and limiting plate 27, the second guiding block 28, the third guiding block 34, the second guiding and limiting plate 27, etc. are all made of insulating materials, such as made of polymer plastics. More specifically, an anti - slip structure is provided on the surface of the base shell 100 facing away from the gear, such as a silica gel strip or a frosted surface, to play an anti - slip role.

[0052] An electric wire 400 is connected to the gear 21, and the other end of the electric wire 400 is connected to an electro - acupuncture treatment instrument.

[0053] As Figure 1 shown, a handle part 11 extends out at the position of the shell head 12 directly opposite to the needle insertion hole 14. Preferably, the vertical center line of the handle part is consistent with the center line of the needle insertion hole 14.

[0054] Specifically, as Figure 2 shown, in this embodiment, a second relief hole 110 through which a power supply wire 400 passes is provided at the top of the housing wall 112 of the handle portion 11 away from the housing head portion, thereby avoiding the influence of the compression or rebound of the spring 29 in this embodiment on the electric wire 400. There may also be other embodiments. The electric conductive wire 400 may also pass through the housing wall 112 of the housing head portion. The position where the electric wire passes through the housing wall 112 is not limited to the above position, but its setting needs to not affect the rotation of the gear and the compression and rebound actions of the spring. This is conventional technology and will not be elaborated here.

[0055] Specifically, a conductive substrate 251 is provided on the inner wall of the gear 200. The conductive brush bristles are connected to the conductive substrate 251. The conductive substrate 251 is connected to an electric wire. When the acupuncture needle is inserted, the conductive brush bristles on the conductive substrate transfer the current transmitted by the electric wire to the needle tool. More specifically, there may be an embodiment in which the electric wire passes through the gear 21 and then through the second relief hole 110, that is, a third relief hole (not shown in the drawings) through which the electric wire can pass is provided on the gear.

[0056] More specifically, the conductive substrate can be installed on the inner wall of the gear through insulating glue.

[0057] The conductive brush bristles of this embodiment can play a role in conducting electricity for the acupuncture needle, and a joint with bristles of corresponding density and length can be selected according to the needle diameter adaptively, so as to also play a role in limiting and fixing the acupuncture needle. Specifically, the diameter of the limiting hole formed by the conductive brush bristles along the inner wall of the gear is equal to or smaller than the diameter of the applicable acupuncture needle.

[0058] The driving mechanism 300 includes an L-shaped control board, and the control board can move horizontally;

[0059] In this embodiment, as Figure 1 and Figure 6 shown, a spring 29 is provided on the driving board 32, and the other end of the spring 29 is connected to the housing wall 112 of the handle portion 11. The spring in this embodiment can play a role in limiting the control board. Specifically, the rebound action of the spring causes the driving board to move to the right, so that the first needle insertion hole is in a closed state to insert and limit the acupuncture needle.

[0060] When this embodiment is specifically applied, as Figure 1As shown, when the first needle insertion hole 14 is in the closed state, at this time, one hand (for example, the left hand) gently pinches the needle body of the acupuncture needle that has been inserted into the skin to stabilize it, and with the other hand, uses a finger to press the pressing plate 31. The spring 400 is in a compressed state, and the driving plate 31 is biased to the left side of the handle part. Then, place the base shell on the skin near the acupuncture needle, close to or adjacent to the skin, and push the first needle insertion hole 14 flatly towards the direction of the acupuncture needle 500 until the needle body of the acupuncture needle 500 is located within the second limiting hole 22. After releasing the pressing plate 31, the driving plate 31 moves to the right under the resilience of the spring 400. The gear bar 33 on the driving plate meshes with the gear teeth, driving the gear to rotate counterclockwise, and then driving the limit adjustment plate 24 to rotate until the side surface of the limit adjustment plate 24 is in contact with the shell wall 112 of the first needle insertion hole 14, until Figure 6 the state of the first needle insertion hole shown. Figure 7 This is the state of retaining the needle after releasing the pressing plate 31. At this time, the connector is placed on the skin, which is simple and convenient to operate, and can reduce the pressure exerted by the self-weight of the connector on the needle body, avoiding deformation or bending of the needle body or the needle body coming out due to the self-weight of the connector.

[0061] When changing from Figures 6 to 1 this state, only need to use a finger to press the pressing plate 31, then the force can be applied to move the driving plate 31 to the left, the spring 400 is compressed, the gear bar on the driving plate meshes with the gear teeth, driving the gear to rotate clockwise, and then driving the limit adjustment plate to rotate until the first needle insertion hole 23 is in a fully open state, and then it can change from Figure 6 this state to Figure 1 this state.

[0062] The base shell 100, the driving mechanism 300, the limit adjustment plate 24, and the gear 21 are all made of insulating materials. More specifically, they can be made of organic plastic materials, such as PLA materials. More specifically, they can be made by 3D printing with PLA materials. Of course, the method is not limited to the above. For example, PMMA materials or polyethylene materials can also be used, which are light in weight and have strength; the conductive substrate 251 and the conductive bristles 25 are made of conductive materials, such as conductive carbon fibers or copper materials.

[0063] Example 2: Refer to Figure 8 a push-type electroacupuncture connector shown. Compared with Example 1, this embodiment does not have a spring. A first magnet 210 is provided on the shell wall 112 of the first needle insertion hole 14 opposite to the limit adjustment plate 24, and a second magnet 211 is provided on the side surface of the limit adjustment plate 24 opposite to the first magnet 210. The first magnet 210 and the second magnet 211 cooperate for magnetic attraction. More specifically, anti-slip strips are provided on the outer surface of the pressing plate 31 located on the shell wall;

[0064] In this embodiment, during the specific process, when the anti-slip strip of the pressing plate 31 is pressed to pull the pressing plate 31 to the right, the gear on the driving plate 32 drives the gear to rotate counterclockwise through the gear rack 33, so that when the first needle insertion hole 14 is in the closed state, the first magnet 210 and the second magnet 211 are fixed by magnetic attraction; when it is necessary to insert the acupuncture needle, that is, when the first needle insertion hole 14 is opened, the pressing plate 31 is pressed forcefully, and the pressing plate moves to the left, then the gear on the driving plate drives the gear to rotate clockwise. After applying force to separate the first magnet 210 and the second magnet 211, the limit adjustment plate 24 rotates clockwise until the first needle insertion hole 14 is in the fully opened state.

[0065] Embodiment 3: Refer to Figure 9 As shown in a flat-push type electro-acupuncture connector, compared with Embodiment 1 in this embodiment, a strip-shaped slot 36 is formed on the side wall of the driving plate 22 facing away from the pressing plate 21. One end of the spring is installed on the bottom wall of the slot 36, and the other end is installed on the shell wall 112. A guiding column 41 passing through the spring is provided on the slot wall 112. The other end of the guiding column 41 is not connected to the bottom wall of the slot and has a spacing. When the first needle insertion hole 14 is in the opened state, the spacing is not less than the stroke distance when the control plate moves to the left until the first needle insertion hole 14 is in the closed state, so as to increase the stability of the spring.

[0066] Embodiment 4: Refer to Figure 10 As shown in a flat-push type electro-acupuncture connector, compared with any one of the flat-push type electro-acupuncture connectors in Embodiments 1 to 3 in this embodiment, a conductive foam 29 is provided on the inner wall of the second limiting hole 22 in this embodiment; wherein the conductive foam 29 includes sponge and conductive cloth, and the conductive cloth is connected to the electric wire 400. More specifically, in an embodiment, the electric wire passes through the gear 21 and then passes through the second relief hole 110, that is, a third relief hole (not shown in the drawing) through which the electric wire can pass is provided on the gear. When the acupuncture needle is inserted, the conductive cloth in contact with the acupuncture needle transfers the current transmitted by the electric wire to the needle tool.

[0067] More specifically, the conductive foam 29 in this embodiment can be bonded to the inner wall of the gear by insulating glue. The conductive foam bonded to the inner wall of the gear encloses to form a limiting hole, and the limiting hole is in interference fit with the applicable acupuncture needle, that is, the diameter of the limiting hole is smaller than the diameter of the applicable acupuncture needle, so as to better limit and fix the acupuncture needle through the deformation of the foam cotton.

[0068] The utility model is more suitable for acupuncture at a certain planar skin position, such as the belly, such as the arm or leg, etc. When in use, the skin to be punctured faces upward.

[0069] The above description is about the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
