Description

Technical Field

[0001] This invention demonstrates a device for the distributed use of multiple acupuncture needles, belonging to the field of medical device technology. Background Technology

[0002] During the treatment of patients, doctors often encounter the need to insert multiple needles into the patient's acupoints at the same time. However, because the existing conventional acupuncture needles are too thin (generally 0.18mm-0.3mm) and too soft, it is not possible to effectively gather and fix the acupuncture needles at the ideal spacing in actual use. The plum blossom needles available on the market have thicker needles, which will increase the surface trauma to the patient during use and also bring the patient a stronger pain. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of not being able to effectively control the spacing of acupuncture needles when using multiple needles simultaneously. To this end, a multi-needle acupuncture needle distributed use device is provided. By distributing multiple needle holes on the base, the acupuncture needles are inserted synchronously along their respective needle holes, so that the acupuncture needles can maintain a specific spacing.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A multi-needle acupuncture needle dispersive application device includes: The base has several needle holes for storing acupuncture needles. The needle holes penetrate the base along its length. A retainer is provided inside each needle hole. The retainer acts on the acupuncture needle to make the acupuncture needle parallel to the axis of the needle hole. The pressing component includes a push needle part corresponding to the needle hole. The pressing component is slidably installed on the top of the base. Each push needle part extends into the corresponding needle hole and is close to the needle tail of the acupuncture needle. The top cover is detachably installed on the top of the base and restricts the pressing member from leaving the base. The top cover is provided with a clearance hole for the pressing member to protrude from the top of the top cover. The pressing member slides towards the base under external force, and the pushing part pushes the tip of the acupuncture needle out of the needle hole; the base is provided with a reset member, and the pressing member is elastically loaded by the reset member and has a tendency to move away from the acupuncture needle.

[0005] The beneficial effects of using the present invention are: The base of this invention is provided with a plurality of needle holes, in which acupuncture needles are installed. During use, medical personnel press the pressing component, which pushes the acupuncture needles through the needle-pushing part, so that the needle tips of the acupuncture needles protrude from the needle holes. Medical personnel can directly insert all acupuncture needles into designated acupoints at the same time. The device can simultaneously insert multiple acupuncture needles into designated acupoints at one time, thereby greatly improving the efficiency of acupuncture and meeting the clinical treatment needs of simultaneous acupuncture at multiple acupoints. In addition, since the spacing between the needle holes is fixed, the spacing between all acupuncture needles after they are inserted into the acupoints is also fixed, thus keeping the acupuncture needles at a reasonable and precise spacing, which helps to improve the acupuncture effect and treatment effect. Secondly, a retainer is set in the needle hole to keep the axis of the acupuncture needle parallel to the axis of the needle hole. This design allows for precise positioning of the needle tip, ensuring a stable, straight-line ejection. This maintains accurate and reliable spacing between acupuncture needles, improving the precision and safety of the procedure and preventing needle skew or wobbling, thus reducing the likelihood of bent or stuck needles. Furthermore, the sliding mechanism of the pressing component facilitates needle ejection, making operation simpler and more effortless. Medical personnel can operate the device with one hand, simplifying the acupuncture process and enhancing its ease of use and clinical suitability. Moreover, the detachable connection between the top cover and base allows for easy removal of the acupuncture needles after use, facilitating disinfection and replacement, as well as cleaning and maintenance of the needle holes, thereby improving the device's safety.

[0006] Preferably, the retainer includes a plurality of positioning rings, all of which are spaced apart along the axial direction of the needle hole. A perforation is provided in the center of each positioning ring. The acupuncture needle includes a needle body that passes through the perforations of all the positioning rings and remains in contact with the inner wall of the perforation. By employing the aforementioned technical solution, multiple positioning rings are set within the needle hole, providing multi-point support for the acupuncture needle body. This results in more even force distribution on the needle body, reliably ensuring that the acupuncture needle remains straight within the needle hole without deviation or wobbling. It also ensures that the needle exit direction is highly consistent with the needle hole axis, thereby maintaining a specific and precise spacing between all acupuncture needles and improving the accuracy of needle insertion. Furthermore, the positioning rings significantly reduce the possibility of contact between the needle body and the inner wall of the needle hole, making the needle movement smoother and reducing the risk of scratching and wear between the needle body and the inner wall of the needle hole. Secondly, the perforation of the positioning ring maintains contact with the needle body, providing reliable radial positioning and preventing obstruction of the acupuncture needle's smooth axial extension. It also reduces the possibility of needle bending or eccentricity, further improving the consistency of needle exit and the safety of needle insertion.

[0007] Preferably, the positioning ring is an elastic element, and it is interference-fitted with the needle body. Using the aforementioned technical solution, the positioning ring can reliably pre-position the acupuncture needle, ensuring its stable retention within the needle hole and preventing it from slipping out, thus improving the storage stability of the acupuncture needle. Furthermore, the elastic structure of the positioning ring allows it to deform to accommodate diameter differences within a reasonable tolerance range, enabling it to adapt to acupuncture needles of varying thicknesses and expanding the applicability of the device.

[0008] Preferably, the inner wall of the needle hole is provided with several annular grooves spaced apart along the axial direction of the needle hole, and the outer periphery of the positioning ring extends into the annular grooves to be positioned inside the needle hole. Using the aforementioned technical solution, the positioning rings can be accurately positioned inside the needle hole through the annular grooves, ensuring that all positioning rings are precisely kept on the same axis. This allows the acupuncture needle to pass straight through all the positioning rings along the axis of the needle hole, significantly improving the accuracy and stability of the acupuncture needle positioning.

[0009] Preferably, the acupuncture needle includes a handle and a body, the outer diameter of the handle being larger than the outer diameter of the body. A limiting protrusion is provided within the needle hole. The pushing part abuts against the handle to push the acupuncture needle, and the limiting protrusion abuts against the handle to restrict further sliding of the acupuncture needle. Using the aforementioned technical solution, the limiting protrusion and the limiting action of the handle precisely restrict the formation of the acupuncture needle's extension, preventing excessive needle tip extension and potential injury to the patient. This significantly improves the safety of acupuncture treatment and ensures that the extension length of all acupuncture needles remains consistent, enhancing the acupuncture effect and therapeutic efficacy.

[0010] Preferably, the base is provided with a mounting groove for accommodating the reset member, one end of the reset member is fixed in the mounting groove, and the other end extends out of the mounting groove and abuts against the pressing member, and the pinholes are distributed on the outside of the mounting groove.

[0011] Preferably, the top of the base has a connecting part, the outer diameter of the connecting part is smaller than the outer diameter of the base, the outer surface of the connecting part is provided with external threads, the top cover is threadedly connected to the connecting part, and after the top cover is connected to the base, the outer surface of the top cover is flush with the outer surface of the base.

[0012] Preferably, the diameter of the pinhole is d, and 0.2mm≤d≤0.4mm.

[0013] Preferably, all pinholes are distributed in a ring on the base, and the diameter of the pitch circle formed by all pinholes is D, and 7mm≤D≤12mm.

[0014] Preferably, the outer surface of the base is provided with anti-slip texture.

[0021] like Figures 1 to 4 As shown in the figure, this embodiment demonstrates a multi-needle 4 distributed use device, including a base 1, a pressing member 3, and a top cover 2. The base 1 has an overall cylindrical structure to facilitate gripping by medical personnel and improve their user experience. The base 1 has several needle holes 11 for storing acupuncture needles 4, which penetrate the base 1 along its length. Each needle hole 11 has a retainer that acts on the acupuncture needle 4 to keep it parallel to the axis of the needle hole 11. The pressing member 3 includes a pressing head 32 and a needle-pushing part 31 corresponding to the needle hole 11. The pressing member 3 is slidably mounted on the top of the base 1, with each needle-pushing part 31 extending into the corresponding needle hole 11 and close to the needle tail 411 of the acupuncture needle 4. The top cover 2 is detachably mounted on the top of the base 1 and prevents the pressing member 3 from detaching from the base 1. The top cover 2 has a protrusion for the pressing member 3. Before use, multiple acupuncture needles 4 are placed into the needle holes 11 of the base 1 through the clearance hole at the top of the cover 2. The number of acupuncture needles 4 can be the same as the number of needle holes 11, or the acupuncture needles 4 can be placed into specific needle holes 11 according to treatment needs. After the acupuncture needles 4 are placed, the pressing member 3 and the cover 2 are assembled with the top of the base 1 in sequence. After assembly, the pushing part 31 of the pressing member 3 extends into the needle hole 11, and the pressing head 32 passes through the clearance hole of the cover 2 and protrudes from the top of the cover 2. During use, the medical staff applies force to the pressing head 32, and the pressing member 3 slides towards the base 1 against the elastic force. The pushing part 31 slides along the needle hole 11 and abuts against the needle tail 411 of the acupuncture needle 4, thereby pushing the acupuncture needle 4 to slide along the needle hole 11 so that the needle tip 421 of the acupuncture needle 4 is pushed out of the needle hole 11. During this process, all the acupuncture needles 4 in the needle holes 11 are pushed out simultaneously.

[0022] In this embodiment, the base 1 is provided with a plurality of needle holes 11, and acupuncture needles 4 are installed in the needle holes 11. During use, medical personnel press the pressing member 3, and the pressing member 3 pushes the acupuncture needles 4 through the needle pushing part 31 so that the needle tip 421 of the acupuncture needle 4 protrudes from the needle hole 11. Medical personnel can directly insert all acupuncture needles 4 into the designated acupoints at the same time. The device can insert multiple acupuncture needles 4 into the designated acupoints at one time, thereby greatly improving the efficiency of acupuncture and adapting to the clinical treatment needs of simultaneous acupuncture at multiple acupoints. In addition, since the spacing between the needle holes 11 is fixed, the spacing between all acupuncture needles 4 after they are inserted into the acupoints is also fixed, thereby keeping the acupuncture needles 4 at a reasonable and precise spacing, which helps to improve the acupuncture effect and treatment effect. Secondly, a retainer is set in the needle hole 11 to keep the acupuncture needles 4 and the needle hole 11 in a reasonable and precise manner. The axes are kept parallel, which allows for precise positioning of the needle tip 421, ensuring that the needle tip 421 is pushed out stably along a straight line. This maintains a precise and reliable spacing between the acupuncture needles 4, improving the accuracy and safety of acupuncture, avoiding the possibility of the acupuncture needles 4 becoming crooked or shaking, and reducing the possibility of bent or stuck needles. In addition, the sliding of the pressing element 3 is used to push out the acupuncture needles 4, making the operation of the device simpler and less strenuous. Medical staff can complete the operation with one hand, which helps to simplify the acupuncture actions of medical staff and thus improve its ease of use and clinical suitability. Furthermore, the upper cover 2 is detachably connected to the base 1. After use, the acupuncture needles 4 in the needle hole 11 can be removed by removing the upper cover 2, so as to disinfect and replace the acupuncture needles 4. At the same time, the inside of the needle hole 11 can also be cleaned and maintained, thereby improving the safety of the device.

[0023] Specifically, in this embodiment, the retainer includes several positioning rings 16, all of which are spaced apart along the axial direction of the needle hole 11. Each positioning ring 16 has a through hole 161 in its center. The acupuncture needle 4 includes a needle body 42, which passes through the through holes 161 of all the positioning rings 16 and remains in contact with the inner wall of the through holes 161. The multiple positioning rings 16 within the needle hole 11 provide multi-point support for the needle body 42, resulting in more even force distribution on the needle body 42. This ensures that the acupuncture needle 4 remains straight within the needle hole 11, without deviation or wobbling, and ensures that the needle exit direction is aligned with the axis of the needle hole 11. Consistency ensures that the spacing between all acupuncture needles 4 remains within a specific and precise range, improving the accuracy of needle insertion. Furthermore, the positioning ring 16 significantly reduces the likelihood of contact between the needle body 42 and the inner wall of the needle hole 11, making the pushing of the acupuncture needle 4 smoother and reducing the risk of scratching and wear between the needle body 42 and the inner wall of the needle hole 11. Secondly, the perforation 161 of the positioning ring 16 maintains contact with the needle body 42, providing reliable radial positioning of the needle body 42 and preventing obstruction of the smooth axial extension of the acupuncture needle 4. It also reduces the possibility of bending or eccentricity of the needle body 42, further enhancing the consistency of needle insertion and the safety of needle application.

[0024] In this embodiment, the positioning ring 16 is an elastic element. The needle body 42 passes through the through hole 161 of the positioning ring 16 and maintains an interference fit with the inner wall of the through hole 161. The inner wall of the needle hole 11 is provided with a plurality of annular grooves 111 spaced apart along the axial direction of the needle hole 11. The outer periphery of the positioning ring 16 extends into the annular grooves 111 to be positioned inside the needle hole 11. The positioning ring 16 can reliably pre-position the acupuncture needle 4, so that the acupuncture needle 4 can be stably held in the needle hole 11, preventing the acupuncture needle 4 from slipping off by itself, which helps to improve the storage stability of the acupuncture needle 4; The outer positioning ring 16 adopts an elastic structure, giving it a certain deformation capability. The positioning ring 16 can accommodate diameter differences of the needle body 42 within a reasonable tolerance range, thus adapting to acupuncture needles 4 of different thicknesses and helping to improve the applicability of this device. Secondly, the positioning ring 16 can be accurately positioned in the needle hole 11 through the annular groove 111, ensuring that all positioning rings 16 are accurately kept on the same axis. This allows the acupuncture needle 4 to pass straight through all positioning rings 16 along the axis of the needle hole 11, significantly improving the positioning accuracy and stability of the acupuncture needle 4.

[0025] Specifically, in this embodiment, the acupuncture needle 4 includes a needle handle 41 and a needle body 42. The end of the needle handle 41 away from the needle body 42 is the needle tail 411, and the end of the needle body 42 away from the needle handle 41 is the needle tip 421. After the acupuncture needle 4 is installed into the needle hole 11, the needle handle 41 is close to the pressing member 3, and the needle body 42 is away from the pressing member 3. During the process of the pressing member 3 sliding towards the base 1, the pushing part 31 first abuts against the needle tail 411, and then pushes the acupuncture needle 4 to slide along the needle hole 11 until the needle tip 421 is pushed out of the needle hole 11. In addition, the outer diameter of the needle handle 41 is larger than the outer diameter of the needle body 42. A limiting protrusion 112 is provided inside the hole 11. The limiting protrusion 112 is closer to the top of the base 1 than the retainer. The push needle part 31 abuts against the needle handle 41 to push the acupuncture needle 4. The limiting protrusion 112 abuts against the needle handle 41 to limit the acupuncture needle 4 from continuing to slide. The limiting cooperation between the limiting protrusion 112 and the needle handle 41 can accurately limit the formation of the acupuncture needle 4, avoid the needle tip 421 from being overextended and causing damage to the patient, and can significantly improve the acupuncture safety of this device. At the same time, it can also ensure that the extension length of all acupuncture needles 4 is consistent, and improve the acupuncture effect and treatment effect.

[0026] Specifically, in this embodiment, the top of the base 1 has a connecting part 13. The outer diameter of the connecting part 13 is smaller than the outer diameter of the base 1. The outer surface of the connecting part 13 is provided with an external thread. The upper cover 2 is threadedly connected to the connecting part 13. After the upper cover 2 is connected to the base 1, the outer surface of the upper cover 2 is flush with the outer surface of the base 1, making the outer surface of the device have a more complete appearance and improving the aesthetics of the device. In addition, the outer surface of the base 1 is provided with anti-slip texture. When medical staff hold the outer surface of the base 1, the anti-slip texture can increase the friction between the base 1 and the palm, reduce the possibility of slippage between the base 1 and the palm, and make the grip of the base 1 more stable and reliable, so as to apply force to the pressing part 3.

[0027] In addition, in this embodiment, the base 1 is provided with a mounting groove 12 for accommodating the reset member 15. One end of the reset member 15 is fixed in the mounting groove 12, and the other end extends out of the mounting groove 12 and abuts against the pressing member 3. The pinholes 11 are distributed on the outside of the mounting groove 12. When the top cover 2 is spliced ​​with the top of the base 1, a receiving cavity 14 is formed between the top cover 2 and the top of the base 1. The pressing member 3 is slidably installed in the receiving cavity 14. One end of the reset member 15 extends into the receiving cavity 14 and abuts against the pressing member 3. The pressing member 3 abuts against the top cover 2 under the action of the reset member 15.

[0028] Regarding the number of pinholes 11, in this embodiment, the number of pinholes 11 provided on the base 1 is in the range of 4 to 10. In order to adapt the device to more usage needs, the number of pinholes 11 configured on the base 1 can be 4, 5, 6, 8 or 10 as required. In addition, all pinholes 11 are evenly distributed in a ring on the base 1, and the diameter of the pitch circle formed by all pinholes 11 is D, and 7mm≤D≤12mm. Specifically, the diameter of the pitch circle can be 7mm, 8.5mm, 10mm or 12mm. Furthermore, in this embodiment, the diameter of pinholes 11 is d, and 0.2mm≤d≤0.4mm. Specifically, the diameter of pinholes 11 can be 0.2mm, 0.3mm, 0.35mm or 0.4mm.
