Description

Technical Field

[0001] This utility model belongs to the field of acupuncture needle technology, specifically relating to an acupuncture needle connection device for electroacupuncture. Background Technology

[0002] Electroacupuncture is an acupuncture method that, based on the acupuncture technique of obtaining qi (deqi), uses an electroacupuncture device to output pulsed current, which is then applied to specific points on the body through filiform needles to prevent and treat diseases. The operation of electroacupuncture includes steps such as selecting acupoints, needling, obtaining qi, connecting the electroacupuncture device, adjusting the current intensity and frequency, and setting the treatment time. The electroacupuncture device can output different waveforms, such as sparse-dense waves, intermittent waves, and continuous waves.

[0003] The connection device for the acupuncture needles used in electroacupuncture is an important component of the electroacupuncture device. Acupuncture treatment usually involves stimulating multiple acupoints on the body simultaneously. Therefore, during electroacupuncture treatment, the electroacupuncture device needs to be able to connect multiple wires at the same time and apply specific electrical signals to the acupuncture needles connected to each wire.

[0004] Currently, there are many connection devices for electroacupuncture needles. The most common method is to use conductive clips to fix the needles. However, because the conductive clips themselves are quite heavy, while the needles are thin and light, the needles may bend due to the weight of the conductive clips, or cause medical accidents. At the same time, it is inconvenient for doctors to clamp or remove the needles. Utility Model Content

[0005] This invention provides a connecting device for acupuncture needles used in electroacupuncture, which aims to replace the method of using conductive clips to hold acupuncture needles in place, thereby preventing the needles from bending during use and making them easier for doctors to handle.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A needle connection device for electroacupuncture includes an inverted frustum-shaped rubber sleeve and a tubular metal elastic element, both of which are fitted along the circumferential direction of the needle. A conductive ring is provided on the inner sidewall of the tubular metal elastic element along the circumferential direction of the needle, and the conductive ring contacts a threaded section on the needle. A deformable limiting sleeve structure is provided on the outside of the inverted frustum-shaped rubber sleeve and the tubular metal elastic element for fitting the inverted frustum-shaped rubber sleeve and the tubular metal elastic element. Through its deformation, the inverted frustum-shaped rubber sleeve and the tubular metal elastic element can be tightened or loosened to clamp or release the needle.

[0008] Preferably, the frustum-shaped rubber sleeve is fitted onto the needle handle; multiple conductive rings are arranged along the circumference of the needle, and the multiple conductive rings are in contact with the threaded section on the needle.

[0009] Preferably, the deformable limiting sleeve structure includes a first rubber sleeve and a second rubber sleeve, the first rubber sleeve being fitted over the outside of the second rubber sleeve, the second rubber sleeve being fitted over the outside of the frustum-shaped rubber sleeve, and the first rubber sleeve being fitted over the outside of the tubular metal elastic element.

[0010] Preferably, the first rubber sleeve and the second rubber sleeve are independent, but the second rubber sleeve is integrally formed with the inverted frustum-shaped rubber sleeve.

[0011] Preferably, the end of the tubular metal elastic element is fitted with a flange, the flange having a contact step, the end of the second rubber block is in surface contact with the contact step along the axial direction of the needle, and the second rubber block is engaged with the flange.

[0012] Preferably, the flange has through holes sequentially opened along the circumference of the needle, and the second rubber block is fixed with a plastic buckle along the circumference of the needle, the plastic buckle being engaged in the through holes.

[0013] Preferably, the end of the plastic buckle has an umbrella-shaped structure, and after the plastic buckle is engaged in the through hole, the umbrella-shaped structure contacts the circumferential surface of the flange.

[0014] Preferably, the first rubber sleeve, the second rubber sleeve, and the inverted frustum-shaped rubber sleeve are integrally formed.

[0015] Preferably, the end of the tubular metal elastic element is fitted with a flange, and the flange has a contact step, and the end of the second rubber block is in surface contact with the contact step along the axial direction of the needle.

[0016] Preferably, the first rubber sleeve is further provided with a guide groove along the circumference of the needle, and the guide groove corresponds to the flange.

[0017] Preferably, the first rubber sleeve, the second rubber sleeve, the tubular metal elastic element, and the inverted frustum-shaped rubber sleeve are all provided with notches; the first rubber sleeve is provided with a fixing structure near its notch, which is used to tighten and fix the acupuncture needle through the fixing structure.

[0018] The beneficial effects of this utility model are:

[0019] This invention primarily relies on the channel formed by multiple limiting pieces on an inverted frustum-shaped rubber sleeve and a tubular metal elastic element to fix the acupuncture needle. A second fixing sleeve is fitted over the inverted frustum-shaped rubber sleeve, and then a first fixing sleeve is fitted over the second fixing sleeve and the tubular metal elastic element. The fixing mechanism is then tightened. With the assistance of various notches, the first rubber sleeve is tightened due to the integral molding of the second and inverted frustum-shaped rubber sleeves, or the integral molding of the first, second, and inverted frustum-shaped rubber sleeves. This tightens the second rubber sleeve, the inverted frustum-shaped rubber sleeve, and the tubular metal elastic element, causing the conductive ring to contact the threaded section on the acupuncture needle, thus fixing the acupuncture needle to the device. Except for the tubular metal elastic element and the conductive ring, which are made of metal, all other components are made of rubber. Therefore, this device has the following advantages:

[0020] The device is lightweight, preventing excessive bending of the needle handle and thus avoiding medical accidents, while also facilitating physician handling. It is easy to operate, allowing physicians to easily connect and remove the needle from any part of the handle, increasing treatment flexibility. It offers high safety, with the tubular metal elastic element reducing damage to the needle body and preventing the risk of breakage at the needle handle-needle connection. It saves materials, as the tubular metal elastic element and conductive ring are only located inside the lower rubber sleeve, reducing the use of metal materials and lowering costs. It is widely adaptable, with a flexible design that can accommodate acupuncture needles of various lengths and thicknesses. Suitable for various treatment needs; cost-effective: due to its simple structure and readily available materials, the production cost is low, which is conducive to the widespread promotion and application of the device; good fixation effect: through the design of the first and second rubber sleeves, tubular metal elastic element, inverted frustum-shaped rubber sleeve and internal notch, the device is not easy to fall off the needle handle, improving the reliability of use; enhances patient experience: the device adopts a snap-on design, eliminating the need to push the connecting device, avoiding changes in needle depth and patient pain caused by pushing and squeezing; superior insulation performance: the rubber sleeve completely wraps the tubular metal elastic element, effectively isolating current and ensuring the safety of the treatment process.

[0029] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0030] Example 1

[0031] like Figure 1-6 As shown, an acupuncture needle connection device for electroacupuncture includes an inverted frustum-shaped rubber sleeve 2 and a tubular metal elastic element 4. Both the inverted frustum-shaped rubber sleeve 2 and the tubular metal elastic element 4 are sleeved along the circumferential direction of the acupuncture needle 5. The inner sidewall of the tubular metal elastic element 4 is provided with a conductive ring 7 made of metal material along the circumferential direction of the acupuncture needle 5. The conductive ring 7 is in contact with the needle handle. The outside of the inverted frustum-shaped rubber sleeve 2 and the tubular metal elastic element 4 is provided with a deformable limiting sleeve structure for sleeved on the inverted frustum-shaped rubber sleeve 2 and the tubular metal elastic element 4. Through its deformation, the inverted frustum-shaped rubber sleeve 2 and the tubular metal elastic element 4 are tightened or loosened so as to clamp or loosen the acupuncture needle 5.

[0032] A frustum-shaped rubber sleeve 2 is fitted onto the needle handle (it should be noted that the needle handle has a threaded section); multiple conductive ring platforms 7 are arranged along the circumference of the needle 5, and multiple conductive ring platforms 7 are in contact with the needle handle, preferably the conductive ring platforms 7 abut against the needle handle.

[0033] The deformable limiting sleeve structure includes a first rubber sleeve 1 and a second rubber sleeve 3. The first rubber sleeve 1 is fitted outside the second rubber sleeve 3, the second rubber sleeve 3 is fitted outside the frustum-shaped rubber sleeve 2, and the first rubber sleeve 1 is fitted outside the tubular metal elastic element 4.

[0034] The first rubber sleeve 1 and the second rubber sleeve 3 are independent, but the second rubber sleeve 3 is integrally formed with the inverted frustum-shaped rubber sleeve 2; the end of the tubular metal elastic element 4 is equipped with a flange 8, and the flange 8 has a contact step 9. The end of the second rubber block 3 is in surface contact with the contact step 9 along the axial direction of the needle 5. The second rubber block 3 is engaged with the flange 8. Specifically, the flange 8 is provided with through holes 11 in sequence along the circumference of the needle 5. The second rubber block 3 is fixed with a plastic buckle 10 along the circumference of the needle 5. The plastic buckle 10 is engaged in the through hole 11. More specifically, the end of the plastic buckle 10 has an umbrella-shaped structure. After the plastic buckle 10 is engaged in the through hole 11, the umbrella-shaped structure is in contact with the circumferential surface of the flange 8.

[0035] The first rubber sleeve 1, the second rubber sleeve 3, the tubular metal elastic element 4, and the inverted frustum-shaped rubber sleeve 2 are all provided with notches; the first rubber sleeve 1 is provided with a fixing structure near its notch, which is used to tighten and fix the acupuncture needle 5 through the fixing structure; specifically, the two ends of the first rubber sleeve 1 are provided with fixing ropes 6, which are used to tighten and fix the first rubber sleeve 1 by connecting the two fixing ropes 6 together.

[0036] The first rubber sleeve 1 is also provided with a guide groove 12 along the circumference of the needle 5, and the guide groove 12 corresponds to the flange 8.

[0037] The connecting device secures the acupuncture needle 5 in the following manner:

[0038] First, insert the acupuncture needle 5 vertically into the channel formed between the multiple limiting sleeves 7 (preferably 4, 5, or 6) on the inverted frustum-shaped rubber sleeve 2 and the tubular metal elastic element 4, so that the inverted frustum-shaped rubber sleeve 2 and the tubular metal elastic element 4 are respectively fitted onto the acupuncture needle 5.

[0039] Next, the second rubber sleeve 3 is fitted onto the inverted frustum-shaped rubber sleeve 2, and the end of the second rubber sleeve 3 contacts the contact step 9, and the plastic buckle 10 is locked in the through hole 11.

[0040] Furthermore, the first rubber sleeve 1 is fitted onto the outside of the second rubber sleeve 3, and the flange 8 is embedded in the guide groove 12.

[0041] Next, hold the two fixing ropes 6 and, with the assistance of the notches, tighten the first rubber sleeve 1. (To better achieve the tightening function, each fixing rope 6 should be rotated at least once around the circumference of the first rubber sleeve 1, so that the fixing rope 6 originally located on the left side of the notch is moved to the right side, and the fixing rope 6 originally located on the right side of the notch is moved to the left side. Then, tie the two fixing ropes 6 tightly. Furthermore, to make the first rubber sleeve 1 tighten even better, a loop similar to a pair of pants can be set around the circumference of the first rubber sleeve 1, called a loop. Then, following the above scheme, pass the fixing rope 6 located on the left side of the notch through the loop and rotate it around the circumference of the first rubber sleeve 1 to the right side of the notch. Similarly, pass the fixing rope 6 located on the right side of the notch through the loop and rotate it around the circumference of the first rubber sleeve 1.) To the left of the notch, tighten the two fixing ropes 6, thereby tightening the second rubber sleeve 3 and the tubular metal elastic element 4 (the tubular metal elastic element 4 is made of copper). This tightens the inverted frustum rubber sleeve 2 and the tubular metal elastic element 4, thus fixing the needle handle and fixing the acupuncture needle 5. The matching of the flange 8 and the guide groove 12 strengthens the radial force on the acupuncture needle 5 when the fixing rope 6 is tightened, thus fixing the acupuncture needle 5 tightly on the device. In addition, since the second rubber sleeve 3 and the inverted frustum rubber sleeve 2 are integrally formed, under the premise that the second rubber sleeve 3 is connected to the tubular metal elastic element 4, when the fixing rope is tightened, the inverted frustum rubber sleeve 2 only holds the acupuncture needle 5 and there is no axial force relative to the acupuncture needle 5.

[0042] Finally, a wire 13 is installed on the tubular metal elastic element 4. The wire 13 is electrically connected to the electroacupuncture device. Through the wire 13, the tubular metal elastic element 4, the conductive ring platform 7 and the acupuncture needle 5 conduct electricity in sequence, and finally, acupuncture is performed on the acupoints of the human body.

[0043] Example 2

[0044] like Figure 7 As shown, this embodiment is basically the same as embodiment 1, except that the first rubber sleeve 1, the second rubber sleeve 3, and the inverted frustum-shaped rubber sleeve 2 are integrally formed.

[0045] The end of the tubular metal elastic element 4 is fitted with a flange 8, and the flange 8 has a contact step 9. The end of the second rubber block 3 is in surface contact with the contact step 9 along the axial direction of the needle 5.

[0046] The working principle of this utility model is basically the same as that of Embodiment 1, except that it does not require a plastic clip to be inserted into the through hole. Therefore, it will not be described in detail here.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
