Description

Technical Field

[0001] The invention belongs to the technical field of acupuncture equipment, and in particular relates to an acupuncture device for blind method. Background Art

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

[0003] However, in double-blind experiments, achieving acupuncture "blindness" is a challenge. Traditional acupuncture treatment relies on the insertion of needles into specific acupuncture points on the human body and the manipulation of the needles to produce therapeutic effects. In this process, both the experimenter and the participant can intuitively feel the presence and stimulation of the needles, so it is difficult to achieve true double-blindness.

[0004] The existing therapeutic acupuncture devices have the problem of uncontrollable acupuncture depth, and the existing placebo acupuncture devices have the problems of poor concealment and large differences in the pricking sensation. These differences may lead to changes in the psychological expectations, reactions and subjective evaluations of the experimental participants, thereby affecting the accuracy of the research results.

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

[0047] like Figure 4 , Figure 5 and Figure 8 As shown, the first depth adjustment component 5 also includes a first internal gear 24, the first drop component 4 also includes a first external gear 25, a blind hole 26 is axially arranged in the middle of the bottom of the first color recognition body 22, the top of the first spring sleeve 23 is interference-fitted with the blind hole 26, and the first spring sleeve 23 is fixed to the blind hole 26; the first internal gear 24 is sleeved on the outside of the first spring sleeve 23 and is located at the bottom of the first color recognition body 22, the first external gear 25 meshing with the first internal gear 24 is arranged on the top of the first connecting cylinder 12, and a disc-shaped first chassis 27 is fixedly arranged below the limit ring 13 at the bottom of the first connecting cylinder 12, and the top of the treatment needle 7 is fixedly connected to the bottom of the first chassis 27. When the first chassis 27 descends, it will drive the treatment needle 7 to descend and extend out of the first needle tube 3, thereby achieving the purpose of acupuncture.

[0048] 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 .

[0049] like Figure 1 and Figure 4As shown, for example, a needle tube cover 28 is provided at the top opening of the first needle tube 3, and the needle tube cover 28 limits the first color recognition body 22 inside the first needle tube 3. The first color recognition body 22 includes a first cylindrical portion 29 and a second cylindrical portion 30 connected in sequence from top to bottom, and 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 needle tube cover 28, and the second cylindrical portion 30 is rotatably connected to the first needle tube 3. The 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 needle tube cover 28.

[0050] like Figure 7 As shown, for example, the first resistance drop component 6 includes an arc-shaped resistance drop portion 33, the outer wall surface of the arc-shaped resistance drop portion 33 is in contact with the inner wall surface of the first needle tube 3, and the arc-shaped resistance drop portion 33 is circumferentially provided with a plurality of step surfaces 331 of different heights, and the position of each step surface 331 corresponds to the position of a color zone on the first color recognition portion 20.

[0051] like Figure 8 As shown, an arc-shaped first stopper 34 is provided on the outer side 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 step surface 331 , and each step surface 331 completely overlaps with the first stopper 34 in the vertical direction.

[0052] In the above technical solution, when not in use, the first reset tube 11 is also in a fixed state under the action of the limit rings 13 at both ends of the connecting tube, and the first spring 21 is in a compressed state. When in use, the first color recognition part 20 is rotated to align the color area of ​​the required acupuncture depth with the color recognition port 19. Different color areas represent different descent 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 step surface 331 of the arc-shaped resistance part 33, so it can only descend 0.5 inches, that is, the acupuncture depth is also 0.5 inches, while green means that the treatment needle 7 can descend 1 inch, that is, the acupuncture depth is also 1 inch, and purple means that the treatment needle 7 can descend 1.5 inches, that is, the acupuncture depth is also 1.5 inches.

[0053] The first color recognition part 20 is rotated under the action of the first outer gear 25 and the first inner gear 24, which can drive the first chassis 27 to rotate. At this time, the corresponding first stopper 34 will be just above the step surface 331 of the arc-shaped resistance part 33 corresponding to this color. The elastic pressing part 9 is pressed to disengage the second protrusion 16 from the bayonet 8, and the first reset tube 11 loses support. Under the action of the first spring 21, the first connecting tube 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 resistance part 33. Since the step surface 331 on the arc-shaped resistance part 33 has different heights, 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, thereby meeting the needs of different acupuncture depths. The reset tube can be reset by the reset rod.

[0054] like Fig. 9 As shown, for example, the placebo needle set 2 has the same appearance as the treatment needle set 1 , and the placebo needle set 2 includes a second needle tube 35 , a second drop assembly 36 , a second depth adjustment assembly 37 , a second drop resistance assembly 38 and a placebo needle 39 .

[0055] Among them, the second depth adjustment component 37 , the second drop component 36 and the placebo needle 39 are arranged in the second needle tube 35 from top to bottom in sequence, and the second drop resistance component 38 is arranged in the second needle tube 35 and is located below the second drop component 36 .

The descending distance is a set value. Generally, the placebo needle 39 moves downward by 1-3 mm, that is, only a pinhole is left on the patient's skin.

[0057] For example, the second needle tube 35 has the same structure as the first needle tube 3 , and the second resistance drop component 38 has the same structure as the first resistance drop component 6 , which will not be described in detail.

[0058] like Fig.10 As shown, for example, the second landing assembly 36 includes a second reset tube 40, a second connecting tube 41, an inner spring sleeve 42, a first acupuncture fixing rod 43 and a second spring 44, wherein the second reset tube 40 has the same structure as the first reset tube 11, and the second connecting tube 41 has the same structure as the first connecting tube 12, which will not be repeated.

[0059] 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.

[0060] 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.

[0061] 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 .

[0062] 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 .

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.

[0064] 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 .

[0065] 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.

[0066] A first stop ring 53 and a second stop ring 54 are provided on the first acupuncture fixing rod 43. The first stop ring 53 is located in the inner spring sleeve 42, and the second stop ring 54 is located below the inner spring sleeve 42. A first inner flange 55 is provided at the bottom of the inner spring sleeve 42, 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 tube 41. The third spring 46 is sleeved on the first acupuncture fixing rod 43, and the top of the third spring 46 contacts the top of the second circular hole 49, and the bottom of the third spring 46 contacts the first stop ring 53.

[0067] When not in use, the second chassis 50 will push the second stop ring 54 upward, so that the third spring 46 is in a compressed state. When the second chassis 50 descends, the third spring 46 is released and pushes the first stop ring 53 downward, and the first acupuncture fixing rod 43 slides in the first circular hole 48. 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 zones of the second color recognition body 45 are rotated, the moving distance of the comfort needle 39 on the first acupuncture fixing rod 43 is the same.

[0068] like Fig.12 As shown, for example, the first depth adjustment assembly 5 includes a first plunger 57 and a fourth spring 58. The first plunger 57 is in a "T" shape. The first plunger 57 includes a third cylindrical portion 59 and a fourth cylindrical portion 60 which are connected in sequence from top to bottom. The outer diameter of the third cylindrical portion 59 is greater than the outer diameter of the fourth cylindrical portion 60. The third cylindrical portion 59 is rotatably connected to the top opening of the first needle tube 3. The fourth cylindrical portion 60 is located inside the first needle tube 3. A second cavity is provided between the fourth cylindrical portion 60 and the first needle tube 3. The fourth spring 58 is located in the second cavity and is sleeved on the fourth cylindrical portion 60.

[0069] like Fig.12 As shown, for example, the first descending assembly 4 includes a first descending tube 61, which is sleeved on the outside of the fourth spring 58 and located between the first needle tube 3 and the fourth spring 58. A second stopper 62 is provided at the bottom of the first descending tube 61, and the bottom of the second stopper 62 is fixedly connected to the treatment needle 7.

[0070] A second buckle 63 matching the bayonet 8 of the first needle tube 3 is disposed on the outer side surface of the first drop tube 61 . The second buckle 63 has the same structure as the first buckle 15 .

[0071] For example, the first descending assembly 4 also includes a second reset rod 64, which 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 descending tube 61, and the other end of the second reset rod 64 is located outside the first needle tube 3. The other end of the second reset rod 64 is provided with a spherical handle for easy operation.

[0072] like Fig.11 and Fig.12 As shown, for example, the first resistance-drop assembly 6 includes a plurality of resistance-drop buttons 65 vertically distributed on the first needle tube 3 .

[0073] like Fig.13 As shown, the anti-drop button 65 includes a press plate 66, a movable rod 67, two clamping blocks 68, a locking block 69 and a blocking rod 70, and the tube wall of the first needle tube 3 is provided with a third circular hole 71 and a fourth circular hole 72 that are interconnected from the outside to the inside at the position of each anti-drop button 65, and the inner diameter of the fourth circular hole 72 is larger than the inner diameter of the third circular hole 71.

[0074] The two clamping blocks 68 are arranged opposite to each other in the fourth circular hole 72 , and one end of the two clamping blocks 68 close to the third circular hole 71 is fixedly connected to the side wall of the fourth circular hole 72 , and a third cavity is defined between the two clamping blocks 68 .

[0075] The push plate 66 is arranged on the outside of the first needle tube 3, the hemispherical locking block 69 is arranged in the third cavity, one end of the movable rod 67 is fixedly connected to the push plate 66, the other end of the movable rod 67 passes through the third circular hole 71 and is fixedly connected to the hemispherical locking block 69, the movable rod 67 is slidingly connected to the third circular hole 71, the baffle rod 70 is arranged in the fourth circular hole 72, and is located at one end of the two clamping blocks 68 away from the third circular hole 71, and the locking block 69 is fixedly connected to the baffle rod 70.

[0076] For example, the third cavity includes a cylindrical segment 73 and an arc segment 74 that are interconnected from outside to inside. The arc surface of the arc segment 74 is tangent to the arc surface of the locking block 69 to form a clamp for the locking block 69, thereby fixing the positions of the movable rod 67 and the blocking rod 70.

[0077] By pressing the button 66, the locking block 69 can be pressed into the arc segment 74 to form a clamp. When in use, the second buckle 63 can be disengaged from the bayonet 8 by pressing the elastic top pressure part 9. The first descending tube 61 drives the treatment needle 7 to descend under the action of the fourth spring 58, and the second stop block 62 stops descending when it descends to contact the stop rod 70 of the set anti-descent button 65.

[0078] like Fig.14 As shown, for example, the second depth adjustment assembly 37 includes a second plunger 75 and a fifth spring 76. The second plunger 75 is "T"-shaped. The second plunger 75 includes a fifth cylindrical portion and a sixth cylindrical portion connected in sequence from top to bottom. The outer diameter of the fifth cylindrical portion is greater than the outer diameter of the sixth cylindrical portion. The fifth cylindrical portion is rotatably connected to the top opening of the second needle tube 35. The sixth cylindrical portion is located inside the second needle tube 35. A fourth cavity is provided between the sixth cylindrical portion and the second needle tube 35. The fifth spring 76 is located in the fourth cavity and is sleeved on the sixth cylindrical portion.

[0079] The second descending assembly 36 includes a second descending tube 77, a second acupuncture fixing rod 78 and a sixth spring 79. The second descending tube 77 has the same structure as the first descending tube 61 and will not be described in detail.

[0080] The second drop tube 77 is sleeved on the outside of the fifth spring 76 and is located between the second needle tube 35 and the fifth spring 76 . A third stopper 80 is provided at the bottom of the second drop tube 77 .

[0081] A fifth cavity is axially provided inside the second plunger 75 , and the second acupuncture fixing rod 78 is located in the fifth cavity. The bottom of the second acupuncture fixing rod 78 passes through the third stopper 80 and is fixedly connected to the placebo needle 39 .

[0082] The second acupuncture fixing rod 78 is provided with a third stop ring 81 and a fourth stop ring 82, the second plunger 75 is provided with a second inner flange 83 at the bottom, 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 in the fifth cavity, the fourth stop ring 82 is located below the fifth cavity, the sixth spring 79 is sleeved on the second acupuncture 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 as the descending tube descends.

[0083] In the above embodiment, no matter what acupuncture depth is set during use, the placebo needle set 2 can only puncture the skin by 1-3 mm.

[0084] In the double-blind clinical study of acupuncture, the treatment needle set 1 and the placebo needle set 2 are randomly assigned to different patients. At the same time, the patients do not know the specific set type they are assigned. This random assignment and unknown nature further ensure the effectiveness of the double-blind design. The placebo needle set 2 and the treatment needle set 1 are completely consistent in appearance design, so that users cannot judge what kind of needle it is just by appearance. The operation process of the two sets is also exactly the same, and patients cannot distinguish the authenticity through operation. In addition, the patient's touch is also the same, whether the treatment needle set 1 or the placebo needle set 2, the needle is in contact with the user.

[0085] For example, a fixing plate 84 is provided below the bottom of the first needle tube 3 and the second needle tube 35, and a detachable adhesive tape 88 is provided at the bottom of the fixing plate 84. The adhesive tape 88 fixes the set to the skin to prevent the set from falling or shifting during the acupuncture process.

[0086] For example, the fixing plate 84 is provided with a first through hole at the position of the adhesive 88, and the first through hole is provided with a blood-imitation piece 85, which includes a cotton ball dipped in iodine, and a plastic film is provided outside the cotton ball. When in 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, and the color of the iodine can also cover up the difference between the treatment group and the placebo group caused by the difference in the amount of bleeding.

[0087] For example, sterile red dry cotton balls are provided on the inner sides of the bottoms of the first needle tube 3 and the second needle tube 35. The dry cotton balls are used to absorb blood stains. Since the amount of bleeding during acupuncture is generally not too large, and sometimes there is no bleeding, even if there is a small amount of bleeding, the red dry cotton balls can cover the traces of bleeding.

[0088] For example, the bottom openings of the first needle tube 3 and the second needle tube 35 are both provided with an acupuncture guide block 86, the arc-shaped resistance-drop portion 33 of the first resistance-drop assembly 6 is arranged around the outside of the acupuncture guide block 86 in the first needle tube 3, and the arc-shaped resistance-drop portion 33 of the second resistance-drop assembly 38 is arranged around the outside of the acupuncture guide block 86 in the second needle tube 35; the acupuncture guide block 86 in the first needle tube 3 is provided with a second through hole matching the diameter of the treatment needle 7, and the acupuncture guide block 86 in the second needle tube 35 is provided with a second through hole matching the diameter of the placebo needle 39, so that the treatment needle 7 and the placebo needle 39 can smoothly pass through the acupuncture guide block 86.

[0089] The outer wall of the acupuncture guide block 86 in the first needle tube 3 is fixedly connected to the inner wall of the arc-shaped resistance drop portion 33 of the first resistance drop assembly 6, and the height of the acupuncture guide block 86 in the first needle tube 3 is lower than the height of the lowest step surface 331 of the arc-shaped resistance drop portion 33 of the first resistance drop assembly 6.

[0090] The acupuncture guide block 86 is used to increase the stability of acupuncture. During the acupuncture process, due to the softness and elasticity of human skin, the needle may sometimes slightly shake or deviate. The existence of the acupuncture guide block 86 can provide a fixed channel so that the needle can smoothly pass through the skin along a predetermined path, reducing the possibility of deviation and shaking (similar to the clamping needle insertion method, preventing accidents such as bending and breaking of the needle).

[0091] For example, both the treatment needle set 1 and the placebo needle set 2 include an electric needle connector 87, which is L-shaped. One end of the electric needle connector 87 of the treatment needle set 1 is located outside the first needle tube 3, and the other end passes through the first needle tube 3 and is fixedly connected to the bottom of the first landing assembly 4. For example, the other end of the electric needle connector 87 of the treatment needle set 1 passes through the first needle tube 3 and is fixedly connected to the bottom of the second stopper 62.

[0092] One end of the electric needle connector 87 of the placebo needle set 2 is located outside the second needle tube 35, and the other end passes through the second needle tube 35 and is fixedly connected to the bottom of the second landing assembly 36. For example, the other end of the electric needle connector 87 of the placebo needle set 2 passes through the second needle tube 35 and is fixedly connected to the bottom of the third stopper 80.

[0093] The electric needle connector 87 is made of metal material, and the second stopper 62 and the third stopper 80 are both made of metal material. This is because in some cases, the treatment needle 7 needs to be connected to electricity to perform electric acupuncture treatment on the patient.

[0094] In summary, the present invention effectively overcomes the shortcomings of the prior art and has high industrial utilization value.

[0095] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions 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.
