Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology. More specifically, it relates to a plum blossom needle. Background Technology
[0002] Plum blossom needles are a commonly used acupuncture tool in clinical practice. The practitioner holds the needle handle and taps the acupoints or specific areas of the body, causing the skin at the tapped site to become congested and red, or to ooze a small amount of blood, thereby achieving the purpose of preventing and treating diseases. Electroacupuncture, based on the acupuncture point of obtaining qi, uses an electroacupuncture device to output a micro-current close to the body's bioelectricity, which is then applied to specific areas of the body through the acupuncture needles to prevent and treat diseases. Electroacupuncture organically combines acupuncture needles with electrical stimulation, improving the efficacy of acupuncture. Inspired by electroacupuncture, the plum blossom needle has been combined with an electroacupuncture device to successfully assemble an electro-plum blossom needle for clinical application, improving the efficacy of treatment for many diseases. Electro-plum blossom needle therapy has a promising application prospect and is worthy of widespread clinical application.
[0003] A placebo-controlled trial is a scientific research method primarily used in fields such as medicine, psychology, and social sciences. In this type of trial, researchers randomly assign participants to two groups: one group receives the experimental intervention, and the other receives a placebo. The purpose of the placebo is to simulate the conditions of the experimental intervention but does not have the actual effect, allowing for comparison with the experimental intervention. A rigorously established placebo is essential for objectively evaluating the efficacy of plum blossom needle therapy. However, for a long time, setting up a placebo in randomized controlled clinical trials of plum blossom needle therapy has been difficult. Utility Model Content
[0004] To address the aforementioned issues, this invention provides a plum blossom needle that can be used in both clinical trials and placebo-controlled trials, facilitating the evaluation of the efficacy of the plum blossom needle.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a plum blossom needle, comprising:
[0007] Needle hub;
[0008] Needle assembly configured on needle hub; and
[0009] A needle handle detachably connected to a needle hub; the needle handle includes a conductive element.
[0010] The needle hub includes a first cavity and a second cavity that are interconnected; the needle assembly is radially floating in the second cavity and extends out of the second cavity.
[0011] The first cavity includes a first limiting position and a second limiting position that are spaced apart along the axial direction of the needle seat;
[0012] The needle handle can be inserted into the first cavity along the needle seat axis and fixed at the first limiting position or the second limiting position;
[0013] The needle assembly can be fixed in contact with the head end of the needle handle fixed at the first limiting position and the conductive component, or it can be fixed without contact with the needle handle fixed at the second limiting position.
[0014] In a preferred embodiment, the needle assembly is disposed within the second cavity via an elastic element; the elastic element is arranged radially along the needle seat; one end of the elastic element abuts against the side wall of the second cavity, and the other end abuts against the needle assembly.
[0015] A preferred embodiment is that the first cavity includes three protrusions formed by the inward protrusion of the inner wall portion of the first cavity; the three protrusions are arranged at intervals along the axial direction of the needle seat;
[0016] Each boss includes a break that makes it a discontinuous annular structure.
[0017] A preferred embodiment is that the end of the needle handle has a protrusion; the protrusion is configured to allow entry into the first cavity through the break.
[0018] The relative rotation of the needle hub and the needle handle can cause the protrusion located in the first cavity to be in a non-corresponding state with the fracture, so that the protrusion on the needle handle is fixed between two adjacent protrusions.
[0019] A preferred embodiment is that the needle assembly includes a movable block located in the second cavity and a plurality of needles fixed on the movable block; the needle handle end fixed at the first limiting position abuts and is fixed on the movable block.
[0020] A preferred embodiment is that an inwardly recessed groove is formed on the bottom surface of the movable block; the head end of the needle handle fixed at the first limiting position is abutted and fixed in the groove.
[0021] In a preferred embodiment, one end of the conductive element is exposed at the tip of the needle handle, and a connector is provided at the other end; an opening is formed at the bottom end of the needle handle; and the connector is exposed through the opening at the bottom end of the needle handle.
[0022] A preferred embodiment is that the conductive element is a conductive spring; the direction of the force of the conductive spring is set along the axial direction of the needle handle.
[0023] A preferred embodiment is that the connector has a through hole formed along the radial direction of the needle handle; the through hole is configured to be connected and fixed to the output end of the electroacupuncture device.
[0024] In a preferred embodiment, the extension direction of the first cavity is perpendicular to the extension direction of the second cavity.
[0025] The beneficial effects of this utility model are as follows:
[0026] This invention, through the cooperation of the needle assembly, needle base, and needle handle, allows for treatment when the needle assembly is fixed to the needle handle at the first limiting position on the needle base. This stimulation can be achieved by tapping with a plum blossom needle combined with electroacupuncture. When the needle assembly is not in contact with the needle handle at the second limiting position on the needle base, the plum blossom needle can be used as a placebo to minimize stimulation of the treatment site, thus enabling the evaluation of the efficacy of the plum blossom needle therapy. This invention can form both clinical trials and placebo-controlled trials of the plum blossom needle therapy by changing the fixed positions of the needle base and needle handle. Furthermore, the appearance and installation method of the two trials are consistent before and during acupuncture, making them convenient to use and reducing production costs.

[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0035] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0036] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.
[0037] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0039] To address the difficulty in implementing a placebo control in existing randomized controlled clinical trials using plum blossom needles, this invention provides a plum blossom needle that combines... Figures 1 to 5 As shown, the plum blossom needle specifically includes: a needle base 1; a needle assembly 2 disposed on the needle base 1; and a needle handle 3 detachably connected to the needle base 1; the needle handle 3 includes a conductive element 31; the conductive element 31 is arranged along the axial direction of the needle handle 3. The conductive element 31 is used to electrically connect the needle tip 22 of the plum blossom needle to the electroacupuncture device. When the two ends of the conductive element 31 are respectively connected to the needle assembly 2 and the electroacupuncture device, electrical connection between the two can be achieved.
[0040] In the above embodiment, the needle holder 1 includes a first cavity 11 and a second cavity 12 that are interconnected. The extension direction of the first cavity 11 is perpendicular to the extension direction of the second cavity 12, that is, the first cavity 11 extends axially along the needle holder 1, while the second cavity 12 extends radially along the needle holder 1. A first opening for inserting the needle handle 3 into the first cavity 11 is provided on the lower end face of the needle holder 1, and a second opening for the needle tip 22 to extend out is provided on the right side of the second cavity 12. The needle assembly 2 is radially floating within the second cavity 12, with the needle tip 22 extending outside the second cavity 12. The floating arrangement of the needle assembly 2 allows it to retract inward when in contact with the skin during the tapping of the treatment site with a plum blossom needle, and pop out after leaving the skin, which can greatly buffer the force on the skin and reduce stimulation to the treatment site. The first cavity 11 includes a first limiting position and a second limiting position spaced apart along the axial direction of the needle holder 1; the needle handle 3 can be inserted into the first cavity 11 along the axial direction of the needle holder 1 and fixed at the first limiting position or the second limiting position; the needle assembly 2 can be fixed by contact with the head end of the needle handle 3 and the conductive element 31 fixed at the first limiting position, or it can be fixed without contact with the head end of the needle handle 3 and the conductive element 31 fixed at the second limiting position. Figure 2As shown, when the needle handle 3 is fixed in the second limiting position of the needle base 1, the needle assembly 2 and the tip of the needle handle 3, as well as the conductive element 31 exposed from the tip of the needle handle 3, are not in contact. That is, the conductive element 31 will not contact the needle assembly 2, and there is no current after the needle tip 22 contacts the skin. By cooperating with the elastically retractable needle assembly 2, the electrical stimulation to the treatment site can be further reduced while reducing acupuncture stimulation. At this time, the plum blossom needle is used as a comfort needle. Figure 1 As shown, when the needle handle 3 is fixed in the first limiting position of the needle base 1, the head end of the needle handle 3 abuts and is fixed to the needle assembly 2. Because the head end of the needle handle 3 is relatively fixed to the needle assembly 2, the needle assembly 2 no longer has the ability to elastically extend or retract. Furthermore, the needle assembly 2 and the electroacupuncture device can be electrically connected through the conductive element 31 inside the needle handle 3. At this time, the plum blossom needle is used as a therapeutic needle. Since the appearance and installation method of the comfort needle and the therapeutic needle are similar, an accurate evaluation of the efficacy of the plum blossom needle can be achieved through comparison between the two. The operation is convenient and quick. It should be noted that... Figure 1 In the diagram, the Y direction represents the axial direction of the needle hub and needle shank, and the X direction represents the radial direction of the needle hub and needle shank.
[0041] In one specific embodiment, reference is made to Figure 3 As shown, the needle assembly 2 is disposed in the second cavity 12 via an elastic element 13; the elastic element 13 is arranged radially along the needle seat 1, and the elastic element 13 may be a spring; one end of the elastic element 13 abuts against the side wall of the second cavity 12, and the other end abuts against the needle assembly 2. During the tapping of the treatment site, after the needle tip 22 contacts the skin, the spring is compressed, and the needle assembly 2 retracts into the second cavity 12. After the needle tip 22 leaves the skin, the needle assembly 2 returns to its original position under the action of the spring's elastic restoring force.
[0042] In one specific embodiment, reference is made to Figure 4 As shown, the first cavity 11 includes three protrusions formed by the inward protrusion of the inner wall surface of the first cavity 11; the three protrusions are arranged axially along the needle holder 1; the protrusion 34 on the needle handle 3 can be rotatably locked between adjacent protrusions, and the three protrusions from bottom to top are the first protrusion 14, the second protrusion 15, and the third protrusion 16. The first limiting position is located between the second protrusion 15 and the third protrusion 16, and the second limiting position is located between the first protrusion 14 and the second protrusion 15. Through the cooperation of adjacent protrusions, the protrusion 34 at the end of the needle handle 3 can be limited and fixed at the first limiting position or the second limiting position. In the first cavity 11, the first limiting position corresponds to the first limiting cavity 17, and the second limiting position corresponds to the second limiting cavity 18.
[0043] Furthermore, each of the protrusions includes a break that forms a discontinuous annular structure; a protrusion 34 is formed at the end of the needle handle 3; the protrusion 34 is configured to enter the first cavity 11 through the break; the relative rotation of the needle seat 1 and the needle handle 3 allows the protrusion 34 located in the first cavity 11 to be in a non-corresponding state with the break. It can be understood that the protrusion 34 can be inserted into the first cavity 11 along with the needle handle 3; the non-corresponding state means that the protrusion 34 can no longer be pulled out through the break.
[0044] In one specific embodiment, the needle assembly 2 includes a movable block 21 located within the second cavity 12 and a plurality of needles 22 fixed to the movable block 21; the needle handle 3, fixed at the first limiting position, abuts and is fixed to the movable block 21, at which time the conductive element 31 and the needles 22 are electrically connected and the movable block 21 will no longer be displaced. It should be noted that a limiting part is provided at the edge of the second opening to restrict the movable block 21 and prevent it from coming out of the second opening.
[0045] Furthermore, in order to better fix the movable block 21 and prevent it from moving and affecting the efficacy evaluation results, an inwardly recessed groove 23 is formed on the bottom surface of the movable block 21; the head end of the needle handle 3, which is fixed at the first limiting position, abuts and is fixed in the groove 23. Through the above settings, the conductive element 31 in the needle handle 3 can be made to contact and conduct with the needle group 2 while the movable block 21 is stably fixed.
[0046] In one specific embodiment, reference is made to Figure 5 As shown, one end of the conductive element 31 is exposed at the tip of the needle handle 3, and the other end is provided with a connector 32; an opening is formed at the bottom end of the needle handle 3; the connector 32 is exposed through the opening at the bottom end of the needle handle 3; the connector 32 is configured to connect to the output end of the electroacupuncture device. When the tip of the needle handle 3 abuts against the needle assembly 2, the conductive element 31 exposed at the tip of the needle handle 3 also makes stable contact with the needle assembly 2, thereby realizing electrical conduction between the electroacupuncture device and the needle tip 22. It can be understood that the connector 32 is made of a conductive material, and the current output by the electroacupuncture device will be conducted to the needle tip 22 through the connector 32 and the conductive element 31, thereby realizing the combination of the tapping stimulation of the plum blossom needle and the electrical stimulation of the electroacupuncture device.
[0047] In one specific embodiment, the conductive element 31 is a conductive spring; one end of the conductive spring protrudes from the top of the needle handle 3, and the other end is connected to a fixed connector 32; the direction of the force of the conductive spring is set along the axial direction of the needle handle 3; a through hole 33 is formed on the connector 32 along the radial direction of the needle handle 3; the through hole 33 is configured to be connected and fixed to the output end of the electroacupuncture device.
[0048] In summary, this invention, through the cooperation of the needle assembly, needle base, and needle handle, allows for treatment when the needle assembly is fixed to the needle handle at the first limiting position on the needle base. This enables treatment by combining plum blossom needle tapping stimulation with electroacupuncture. When the needle assembly is not in contact with the needle handle at the second limiting position on the needle base, the plum blossom needle can be used as a placebo to minimize stimulation of the treatment site, thus allowing for the evaluation of the efficacy of the plum blossom needle therapy. This invention can form both plum blossom needle clinical trials and placebo-controlled trials by changing the fixed positions of the needle base and needle handle. Furthermore, the appearance and installation methods of the resulting plum blossom needle clinical trials and placebo-controlled trials are consistent before and during acupuncture, and the invention is convenient to use, reducing production costs.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
