Description

Technical Field

[0001] The present invention belongs to the technical field of acupuncture needles, and particularly relates to an acupuncture device for blind method. Background Art

[0002] In medical research and clinical practice, the double-blind experiment, as a rigorous clinical trial research method, is widely used to evaluate the effects of drugs, therapies, or interventions. The core feature of the double-blind experiment is that neither the experimenter nor the participants know which participants receive the real treatment (experimental group) or placebo (control group), thus minimizing the impact of subjective bias and placebo effect on the clinical research results to the greatest extent.

[0003] However, in the double-blind experiment, achieving the "blind method" of acupuncture is a challenge. Traditional acupuncture treatment relies on inserting the needle into specific acupoints of the human body and generating therapeutic effects through manipulative techniques. During this process, both the experimenter and the participants can intuitively feel the presence and stimulation of the needle, so it is difficult to achieve true double-blindness.

[0004] Existing therapeutic acupuncture devices have problems with uncontrollable acupuncture depth, and existing placebo acupuncture devices have problems such as poor concealment and large differences in the sense of prick, and these differences may lead to changes in the psychological expectations, reactions, and subjective evaluations of experimental participants, thus affecting the accuracy of research results.

[0005] Therefore, developing a therapeutic acupuncture device that can achieve adjustable control of acupuncture depth, better simulate the real acupuncture feeling, and achieve a higher degree of concealment for the placebo acupuncture device, and at the same time can set the acupuncture depth, is of great significance for improving the accuracy of the evaluation of acupuncture therapy in double-blind experiments.

[0088] The bottom of the first spring sleeve 23 is located in the first connecting tube 12 . The first spring 21 is disposed in the first spring sleeve 23 . The top of the first spring 21 contacts the bottom of the blind hole 26 . The bottom of the first spring 21 contacts the first chassis 27 .

[0089] like Figure 1 and Figure 4As shown, for example, a syringe cap 28 is provided at the top opening of the first syringe 3. The syringe cap 28 confines the first color-identifying body 22 inside the first syringe 3. The first color-identifying body 22 includes a first cylindrical portion 29 and a second cylindrical portion 30 connected in sequence from top to bottom. An annular positioning step 31 is provided at the connection between the first cylindrical portion 29 and the second cylindrical portion 30. The first cylindrical portion 29 passes through the syringe cap 28, and the second cylindrical portion 30 is rotatably connected to the first syringe 3. A blind hole 26 is provided at the bottom of the second cylindrical portion 30, and an annular limiting step 32 matching the annular positioning step 31 is provided at the bottom of the syringe cap 28.

[0090] As Figure 7 shown, for example, the first resistance-dropping component 6 includes an arc-shaped resistance-dropping portion 33. The outer wall surface of the arc-shaped resistance-dropping portion 33 fits against the inner wall surface of the first syringe 3. A plurality of stepped surfaces 331 with different heights are provided on the arc-shaped resistance-dropping portion 33 in the circumferential direction, and the position of each stepped surface 331 corresponds to the position of a color area on the first color-identifying portion 20.

[0091] As Figure 8 shown, an arc-shaped first stopper 34 is provided on the outer side surface of the first chassis 27. The arc length of the cross-section of the arc-shaped first stopper 34 is equal to the arc length of the stepped surface 331, and each stepped surface 331 completely coincides with the first stopper 34 in the vertical direction.

[0092] In the above technical solution, when not in use, the first return tube 11 is also in a fixed state under the action of the limiting rings 13 at both ends of the connecting cylinder, and the first spring 21 is in a compressed state. When in use, rotate the first color-identifying portion 20 to align the color area corresponding to the required acupuncture depth with the color-identifying opening 19. Different color areas represent different descending amplitudes of the treatment needle 7, that is, different acupuncture depths. For example, red means that the first stopper 34 can be blocked by the highest stepped surface 331 of the arc-shaped resistance-dropping portion 33, so it can only descend 0.5 cun, that is, the acupuncture depth is also 0.5 cun. Green means that the treatment needle 7 can descend 1 cun, that is, the acupuncture depth is also 1 cun. Purple means that the treatment needle 7 can descend 1.5 cun, that is, the acupuncture depth is also 1.5 cun.

[0093] When the first color recognition part 20 rotates under the action of the first outer gear 25 and the first inner gear 24, the first chassis 27 can be driven to rotate. At this time, the corresponding first stopper 34 will just be located above the step surface 331 of the arc-shaped descent resistance part 33 corresponding to this color. Press the elastic pressing part 9 to disengage the second convex block 16 from the bayonet 8. The first return tube 11 loses support. Under the action of the first spring 21, the first connecting cylinder 12 and the first chassis 27 will move downward, driving the first stopper 34 to move downward. When the first stopper 34 descends, it will contact the step surface 331 corresponding to the arc-shaped descent resistance part 33. Since the height of the step surface 331 on the arc-shaped descent resistance part 33 is different, the first stopper 34 will stop descending after contacting the corresponding step surface 331, thereby driving the treatment needle 7 to descend to the corresponding depth, and further meeting the needs of different acupuncture depths. The return tube can be reset through the reset rod.

[0094] As Figure 9 shown, for example, the placebo needle set 2 has the same outer shape as the treatment needle set 1. The placebo needle set 2 includes a second needle tube 35, a second descent assembly 36, a second depth adjustment assembly 37, a second descent resistance assembly 38, and a placebo needle 39.

[0095] Among them, the second depth adjustment assembly 37, the second descent assembly 36, and the placebo needle 39 are arranged in the second needle tube 35 from top to bottom in sequence. The second descent resistance assembly 38 is arranged in the second needle tube 35 and is located below the second descent assembly 36.

[0096] The second depth adjustment assembly 37 is connected to the second descent assembly 36. The placebo needle 39 is slidably connected to the second descent assembly 36. The second descent resistance assembly 38 is arranged in the second needle tube 35 and is located below the second descent assembly 36. The second descent resistance assembly 38 is configured to adjust the position of the second descent assembly 36 in the second needle tube 35. The second descent assembly 36 is configured to control the descending distance of the placebo needle 39 to a set value when moving downward in the second needle tube 35. Generally, the descending distance of the placebo needle 39 is 1 - 3 mm, that is, only leaving a needle hole on the patient's skin.

[0097] For example, the second needle tube 35 has the same structure as the first needle tube 3, and the second descent resistance assembly 38 has the same structure as the first descent resistance assembly 6, which will not be elaborated here.

[0098] As Figure 10 shown, for example, the second descent assembly 36 includes a second return tube 40, a second connecting cylinder 41, an inner spring sleeve 42, a first acupuncture fixing rod 43, and a second spring 44. Among them, the second return tube 40 has the same structure as the first return tube 11, and the second connecting cylinder 41 has the same structure as the first connecting cylinder 12, which will not be elaborated here.

[0099] For example, the second depth adjustment assembly 37 includes a second color recognition part and a third spring 46. The second color recognition part is arranged at the top opening of the second needle tube 35. The second color recognition part includes a second color recognition body 45 and a second spring sleeve 47. The second color recognition body 45 is cylindrical. The bottom of the second color recognition body 45 is rotatably connected to the top opening of the second needle tube 35. The top of the second color recognition body 45 is located outside the second needle tube 35, so the user can rotate the second color recognition body 45.

[0100] A plurality of color zones are circumferentially arranged at the same height as the color recognition port 19 of the second needle tube 35 on the outer side surface of the second color recognition body 45. The colors of the plurality of color zones are different. The plurality of color zones are the same size as the color recognition port 19 on the second needle tube 35. Each color zone forms a small block-shaped protrusion structure. The plurality of color zones horizontally surround the second color recognition body 45. Rotating the second color recognition body 45 can make each color zone fall into the color recognition port 19 of the second needle tube 35.

[0101] A first circular hole 48 and a second circular hole 49 are connected to each other in sequence from top to bottom in the middle of the second color recognition body 45 along the axial direction. The inner diameter of the second circular hole 49 is greater than the inner diameter of the first circular hole 48 .

[0102] The top of the second spring sleeve 47 is interference fit with the second circular hole 49 , and a disc-shaped second chassis 50 is fixedly disposed below the limiting ring 13 at the bottom of the second connecting tube 41 .

[0103] The bottom of the second color recognition body 45 is transmission connected to the top of the second connecting tube 41. For example, the second depth adjustment assembly 37 also includes a second internal gear 51, and the second landing assembly 36 also includes a second external gear 52. The second internal gear 51 is sleeved on the outside of the second spring sleeve 47 and is located at the bottom of the second color recognition body 45. The top of the second connecting tube 41 is provided with a second external gear 52 that meshes with the second internal gear 51.

[0104] The bottom of the second spring sleeve 47 is located in the second connecting tube 41 , the second spring 44 is disposed in the second spring sleeve 47 , the top of the second spring 44 contacts the top of the second circular hole 49 , and the bottom of the second spring 44 contacts the second chassis 50 .

[0105] The inner spring sleeve 42 is arranged inside the second spring sleeve 47, the top of the inner spring sleeve 42 is fixedly connected to the top of the second circular hole 49, the second spring 44 is sleeved on the outside of the inner spring sleeve 42, the first acupuncture fixing rod 43 is located in the inner spring sleeve 42, the top of the first acupuncture fixing rod 43 is slidably connected to the first circular hole 48, and the bottom of the first acupuncture fixing rod 43 passes through the second chassis 50 and is fixedly connected to the placebo needle 39.

[0106] A first needle puncture fixing rod 43 is provided with a first stop ring 53 and a second stop ring 54. The first stop ring 53 is located inside an inner spring sleeve 42, and the second stop ring 54 is located below the inner spring sleeve 42. The bottom of the inner spring sleeve 42 is provided with a first inner flange 55, and the first inner flange 55 is located between the first stop ring 53 and the second stop ring 54. A second groove 56 matching the second stop ring 54 is provided at the connection between the second chassis 50 and the second connecting cylinder 41. A third spring 46 is sleeved on the first needle puncture fixing rod 43. The top of the third spring 46 contacts the top of the second round hole 49, and the bottom of the third spring 46 contacts the first stop ring 53.

[0107] In the unused state, the second chassis 50 will push the second stop ring 54 upward, causing the third spring 46 to be in a compressed state. When the second chassis 50 descends, the third spring 46 is released and pushes the first stop ring 53 downward. The first needle puncture fixing rod 43 slides in the first round hole 48, and the first stop ring 53 stops descending when it contacts the first inner flange 55 of the inner spring sleeve 42. Therefore, no matter how the color areas of the second color recognition body 45 are rotated, the moving distance of the comfort needle 39 on the first needle puncture fixing rod 43 is the same.

[0108] As Figure 12 shown, for example, the first depth adjustment component 5 includes a first plunger 57 and a fourth spring 58. The first plunger 57 is in a "T" shape and includes a third cylindrical part 59 and a fourth cylindrical part 60 connected in sequence from top to bottom. The outer diameter of the third cylindrical part 59 is larger than that of the fourth cylindrical part 60. The third cylindrical part 59 is rotatably connected to the top opening of the first syringe 3, and the fourth cylindrical part 60 is located inside the first syringe 3. There is a second cavity between the fourth cylindrical part 60 and the first syringe 3, and the fourth spring 58 is located in the second cavity and sleeved on the fourth cylindrical part 60.

[0109] As Figure 12 shown, for example, the first lowering component 4 includes a first lowering tube 61. The first lowering tube 61 is sleeved outside the fourth spring 58 and is located between the first syringe 3 and the fourth spring 58. The bottom of the first lowering tube 61 is provided with a second stop block 62, and the bottom of the second stop block 62 is fixedly connected to the treatment needle 7.

[0110] The outer side of the first lowering tube 61 is provided with a second buckle 63 matching the bayonet 8 of the first syringe 3, and the second buckle 63 has the same structure as the first buckle 15.

[0111] For example, the first lowering component 4 further includes a second reset rod 64. The second reset rod 64 passes through the reset groove 17. One end of the second reset rod 64 is fixedly connected to the second stop block 62 at the bottom of the first lowering tube 61, and the other end of the second reset rod 64 is located outside the first syringe 3. A spherical handle is provided at the other end of the second reset rod 64 for easy operation.

[0112] As Figure 11 and Figure 12 shown, for example, the first descent prevention component 6 includes a plurality of descent prevention buttons 65 vertically distributed on the first syringe 3.

[0113] As Figure 13 shown, wherein the descent prevention button 65 includes a pressing plate 66, a movable rod 67, two clamping blocks 68, a locking block 69 and a retaining rod 70. The pipe wall of the first syringe 3 is successively provided with a third round hole 71 and a fourth round hole 72 which are communicated with each other from outside to inside at the position of each descent prevention button 65. The inner diameter of the fourth round hole 72 is larger than the inner diameter of the third round hole 71.

[0114] The two clamping blocks 68 are oppositely arranged in the fourth round hole 72. One end of the two clamping blocks 68 close to the third round hole 71 is fixedly connected with the side wall of the fourth round hole 72. There is a third cavity between the two clamping blocks 68.

[0115] The pressing plate 66 is arranged outside the first syringe 3. The hemispherical locking block 69 is arranged in the third cavity. One end of the movable rod 67 is fixedly connected with the pressing plate 66. The other end of the movable rod 67 passes through the third round hole 71 and is fixedly connected with the hemispherical locking block 69. The movable rod 67 is slidably connected with the third round hole 71. The retaining rod 70 is arranged in the fourth round hole 72 and is located at one end of the two clamping blocks 68 far from the third round hole 71. The locking block 69 is fixedly connected with the retaining rod 70.

[0116] For example, the third cavity includes a cylindrical section 73 and an arc section 74 which are communicated with each other from outside to inside. The arc surface of the arc section 74 is tangent to the arc surface of the locking block 69 to form a clamping on the locking block 69, thereby fixing the positions of the movable rod 67 and the retaining rod 70.

[0117] By pressing the pressing plate 66, the locking block 69 can be pressed into the arc section 74 to form a clamping. During use, by pressing the elastic pressing part 9, the second buckle 63 can be separated from the bayonet 8. The first dropping tube 61 drives the treatment needle 7 to descend under the action of the fourth spring 58. When the second stop block 62 descends to contact the retaining rod 70 of the set descent prevention button 65, the descent stops.

[0118] As Figure 14 shown, for example, the second depth adjustment component 37 includes a second plunger 75 and a fifth spring 76. The second plunger 75 is in a "T" shape. The second plunger 75 includes a fifth cylindrical part and a sixth cylindrical part which are connected in sequence from top to bottom. The outer diameter of the fifth cylindrical part is larger than the outer diameter of the sixth cylindrical part. The fifth cylindrical part is rotatably connected with the top opening of the second syringe 35. The sixth cylindrical part is located inside the second syringe 35. There is a fourth cavity between the sixth cylindrical part and the second syringe 35. The fifth spring 76 is located in the fourth cavity and sleeved on the sixth cylindrical part.

[0119] The second landing assembly 36 includes a second landing tube 77, a second acupuncture needle fixing rod 78, and a sixth spring 79. The structure of the second landing tube 77 is the same as that of the first landing tube 61, so it will not be described in detail here.

[0120] The second landing tube 77 is sleeved outside the fifth spring 76, located between the second needle tube 35 and the fifth spring 76. A third stopper 80 is provided at the bottom of the second landing tube 77.

[0121] A fifth cavity is axially provided inside the second plunger 75. The second acupuncture needle fixing rod 78 is located in the fifth cavity. The bottom of the second acupuncture needle fixing rod 78 passes through the third stopper 80 and is fixedly connected to the placebo needle 39.

[0122] A third stop ring 81 and a fourth stop ring 82 are provided on the second acupuncture needle fixing rod 78. A second inner flange 83 is provided at the bottom of the second plunger 75. The second inner flange 83 is located between the third stop ring 81 and the fourth stop ring 82. The third stop ring 81 is located inside the fifth cavity, and the fourth stop ring 82 is located below the fifth cavity. The sixth spring 79 is sleeved on the second acupuncture needle fixing rod 78. The top of the sixth spring 79 contacts the top of the fifth cavity, and the bottom of the sixth spring 79 contacts the third stop ring 81. When this solution is used, the placebo needle 39 does not descend with the landing tube.

[0123] In the above-mentioned embodiment, no matter what acupuncture depth is set during use, the placebo needle set 2 can only pierce the skin by 1 - 3 mm.

[0124] In the double-blind clinical study of acupuncture, the treatment needle set 1 and the placebo needle set 2 will be randomly assigned to different patients. At the same time, the patients also do not know the specific type of the assigned set. This random assignment and unknownness further ensure the effectiveness of the double-blind design. The placebo needle set 2 and the treatment needle set 1 are completely identical in appearance design, making it impossible for users to judge what kind of needle it is only by appearance. And the operation processes of the two sets are also completely the same, and patients cannot distinguish the true from the false by operation. In addition, the patient's touch is the same, and the needles of both the treatment needle set 1 and the placebo needle set 2 contact the user.

[0125] For example, a fixing plate 84 is provided below the bottoms of the first needle tube 3 and the second needle tube 35. A sticker 88 is detachably provided at the bottom of the fixing plate 84. The set is fixed to the skin through the sticker 88 to prevent the set from falling or shifting during the acupuncture process.

[0126] For example, the fixed plate 84 is provided with a first through hole at the position of the adhesive patch 88, and a blood-like component 85 is arranged in the first through hole. The blood-like component 85 includes a cotton ball impregnated with iodophor, and a plastic film is provided outside the cotton ball. During use, both the treatment needle 7 and the placebo needle 39 will pierce the cotton ball, so that the skin after acupuncture can be disinfected. At the same time, the color of the iodophor can also cover up the differences between the treatment group and the placebo group caused by the differences in the amount of bleeding.

[0127] For example, sterile red dry cotton balls are arranged on the inner sides of the bottoms of the first syringe 3 and the second syringe 35. The dry cotton balls are used to absorb blood. Since the amount of bleeding is generally not too large during the acupuncture process and sometimes there is no bleeding, even if there is a small amount of bleeding, the red dry cotton balls can cover up the bleeding marks.

[0128] For example, acupuncture guiding blocks 86 are arranged at the bottom openings of the first syringe 3 and the second syringe 35. The arc-shaped descending parts 33 of the first descending component 6 surround the outside of the acupuncture guiding block 86 in the first syringe 3, and the arc-shaped descending parts 33 of the second descending component 38 surround the outside of the acupuncture guiding block 86 in the second syringe 35. A second through hole matching the diameter of the treatment needle 7 is arranged on the acupuncture guiding block 86 in the first syringe 3, and a second through hole matching the diameter of the placebo needle 39 is arranged on the acupuncture guiding block 86 in the second syringe 35, so that the treatment needle 7 and the placebo needle 39 can smoothly pass through the acupuncture guiding block 86.

[0129] The outer wall of the acupuncture guiding block 86 in the first syringe 3 is fixedly connected to the inner wall of the arc-shaped descending part 33 of the first descending component 6, and the height of the acupuncture guiding block 86 in the first syringe 3 is lower than the height of the lowermost step surface 331 of the arc-shaped descending part 33 of the first descending component 6.

[0130] The acupuncture guiding block 86 is used to increase the stability of acupuncture. During the acupuncture process, due to the softness and elasticity of the human skin, the needle may sometimes produce slight shaking or deviation. The presence of the acupuncture guiding block 86 can provide a fixed channel, enabling the needle to smoothly pass through the skin along a predetermined path, reducing the possibility of deviation and shaking (similar to the clamping acupuncture method to prevent accidental situations such as bent needles and broken needles).

[0131] For example, both the treatment needle set 1 and the placebo needle set 2 include an electro-acupuncture connector 87. The electro-acupuncture connector 87 is L-shaped. One end of the electro-acupuncture connector 87 of the treatment needle set 1 is located outside the first syringe 3, and the other end penetrates the first syringe 3 and is fixedly connected to the bottom of the first descending component 4. For example, the other end of the electro-acupuncture connector 87 of the treatment needle set 1 penetrates the first syringe 3 and is fixedly connected to the bottom of the second stop block 62.

[0132] One end of the electro-acupuncture connector 87 of the placebo needle set 2 is located outside the second needle tube 35, and the other end penetrates through the second needle tube 35 and is fixedly connected to the bottom of the second landing component 36. For example, the other end of the electro-acupuncture connector 87 of the placebo needle set 2 penetrates through the second needle tube 35 and is fixedly connected to the bottom of the third stopper 80.

[0133] The electro-acupuncture connector 87 is made of a metal material, and both the second stopper 62 and the third stopper 80 are made of a metal material, which is for the purpose of electrically connecting the treatment needle 7 in some cases to perform electro-acupuncture treatment on the patient.

[0134] In summary, the present invention effectively overcomes the disadvantages in the prior art and has high industrial utilization value.

[0135] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
