Description

Technical Field

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

[0002] Acupuncture refers to inserting needles into the patient's body at a certain angle under the guidance of traditional Chinese medicine theory, using techniques such as lifting, inserting, and twisting to stimulate specific parts of the human body in order to achieve the purpose of treating diseases.

[0003] To study the effects of acupuncture, doctors often use blind controlled experiments, dividing patients into an experimental group and a control group. Patients in the control group do not receive real acupuncture, but only simulate the effects of acupuncture to eliminate the influence of the patient's subjective consciousness, so as to compare the efficacy of acupuncture.

[0004] At present, blind control experiments often use placebo needles to evaluate the effectiveness of acupuncture therapy. Placebo needles can only be achieved with the help of auxiliary devices. At present, the placebo needle auxiliary devices that are widely used at home and abroad are as follows: blunt needles, plastic catheters, foam devices, plastic sheets, retractable fake needles, etc. Their characteristics are summarized as follows: ① The needle tip is round and blunt to simulate the pricking sensation of a real acupuncture needle touching the skin; ② The part of the needle tip that contacts or does not contact the skin is fixed with the help of auxiliary tools; ③ It does not penetrate the skin, and has a certain "placebo needle" blind effect. The introduction of auxiliary devices makes "fake acupuncture" closer to "placebo needles" and is widely used in acupuncture clinical RCT (randomized controlled trials) research. The placebo needles of the auxiliary devices have achieved the appearance of "fake and real", but most of the auxiliary devices currently need to be equipped with real needles and fake needles. The fake needles are specially designed to make the subjects feel a certain sense of skin touch during acupuncture without actually piercing, which increases the complexity of the device and is not conducive to clinical promotion and use.

[0044] Furthermore, the bottom surface of the first fixing member 2100 is provided with an inwardly bent edge, and the inner diameter of the edge is preferably slightly larger than the outer diameter of the movable part 2210, so that the movable part 2210 can move freely up and down, and can also block the damping member 2300 so that it does not slide out of the first fixing member 2100.

[0045] Further, such as Figure 1 As shown, a circular opening is provided on the upper surface of the housing 1000 to facilitate the upward and downward movement of the movable member 2200 . Preferably, the diameter of the circular opening is consistent with the inner diameter of the first fixed member 2100 .

[0046] The movable part 2200 is arranged in the first fixed part 2100, and the movable part 2200 can move freely in the first fixed part 2100. The movable part 2200 includes a movable part 2210 and a connecting part 2220. The movable part 2210 is arranged at the lower end of the movable part 2200. The movable part 2210 is preferably a hollow cylinder. The connecting part 2220 is arranged at the upper end of the movable part 2200. The connecting part 2220 is preferably a hollow cylinder.

[0047] Further, the movable part 2200 also includes a positioning part 2230, which is arranged between the movable part 2210 and the connecting part 2220. The middle of the positioning part 2230 is a hollow cylinder. Preferably, the inner diameter of the cylinder of the positioning part 2230 is consistent with the inner diameter of the connecting part 2220. The outer side surface of the cylinder in the middle of the positioning part 2230 is uniformly distributed with sheet structures along the axial direction. The number of sheet structures can be set as needed. In this embodiment, the number of sheet structures is 4, and the shape of the sheet structure is preferably a rectangular sheet 2231. The rectangular sheet 2231 and the first fixing part 2100 are connected. There is a gap between them so that the positioning part 2230 can move freely up and down in the first fixing member 2100. Preferably, the diameter of the circumscribed circle of the rectangular sheet 2231 is consistent with the outer diameter of the movable part 2210. The rectangular sheet 2231 is provided with a positioning groove, which is a first groove 2232 horizontally arranged from the outside to the inside of the rectangular sheet 2231. The vertical section of the first groove 2232 is preferably rectangular. The size, spacing and number of the first groove 2232 are set as required, and can be evenly distributed on the entire rectangular sheet 2231, or only set at the upper and lower ends of the rectangular sheet 2231. The movable part 2210, the positioning part 2230 and the connecting part 2220 are preferably an integrally formed structure.

[0048] Further, such as Fig.10 As shown, the pressing assembly 2000 is also provided with a retaining member 2700, which is arranged on the upper surface of the housing 1000. The retaining member 2700 is preferably a hook-shaped thin sheet structure, one end of which is a straight plate shape and the other end is a semicircular ring. One end of the straight plate shape is fixed to the upper surface of the housing 1000 by a pin shaft, so that the retaining member 2700 can rotate freely around the pin shaft. The size of the semicircular ring is adapted to the size of the first groove 2232 on the positioning part 2230. The thickness of the semicircular ring is slightly smaller than the distance between the upper and lower sides of the first groove 2232, so that one end of the semicircular ring on the retaining member 2700 can be inserted into the first groove 2232, so that the movable member 2200 is kept fixed in the required position and is not easy to slide. The number of the first grooves is set as needed, as long as the movable member 2200 needs to be fixed in the current position by inserting the retaining member 2700 into the first groove 2232.

[0049] The pressing member 2400 is arranged above the movable member 2200, and the pressing member 2400 is connected to the connecting portion 2220. The pressing member 2400 is preferably a hollow cylinder, and a step surface 2410 is arranged on the inner wall of the pressing member 2400. An internal thread is arranged on the inner wall below the step surface 2410. The size of the internal thread of the pressing member 2400 is adapted to the size of the external thread of the connecting portion 2220, so that the pressing member 2400 is connected to the movable member 2200 through threads, and the step surface The inner wall of the pressing piece 2400 above 2410 is a light hole, and the inner diameter of the light hole is smaller than the inner diameter of the threaded hole below the step surface 2410. The clamping piece 2500 is placed between the connecting part 2220 and the pressing piece 2400. The clamping piece 2500 is a circular thin sheet, and the outer diameter of the clamping piece 2500 is preferably consistent with the outer diameter of the connecting part 2220. By rotating the pressing piece 2400, the clamping piece 2500 is tightly fixed between the pressing piece 2400 and the connecting part 2220. The clamping piece 2500 is used to fix the acupuncture needle. The material of the clamping piece 2500 is an elastic material, and rubber, plastic and other materials can be selected. Latex is preferably latex. Latex has good elasticity, flexibility and good tensile properties, which can make the acupuncture needle pass through it easily, and can also play a fixed supporting role for the acupuncture needle to prevent the acupuncture needle from falling off. The acupuncture needle can be selected from existing products on the market according to needs. Before acupuncture, the control group adjusted the length of the acupuncture needle inserted into the shell 1000 according to the height of the shell 1000 and the length of the acupuncture needle to ensure that the length of the acupuncture needle inserted into the shell 1000 was not higher than the height of the shell, which could prevent the needle from injuring the subject's skin. After adjusting the position, the acupuncture needle could be fixed on the clamping member 2500 under the elastic force and friction force of the clamping member 2500.

[0050] The damping member 2300 is mounted on the movable part 2210, and is located between the movable part 2200 and the first fixed part 2100. The damping member 2300 is annular in shape. Preferably, the inner diameter of the damping member 2300 is slightly smaller than the outer diameter of the movable part 2210, so that the damping member 2300 is firmly fixed on the movable part 2210, and is not easy to slide on the movable part 2210. The outer diameter of the damping member 2300 is slightly larger than the inner diameter of the first fixed part 2100, and the damping member 2300 and the first fixed part 2100 are interference fit, so that the damping member 2300 and the inner wall of the first fixed part 2100 are closely fitted, so that the movable part 2200 can slide in the first fixed part 2100, and can stay and be fixed at any position of its inner wall, and is not easy to fall off. The damping member 2300 is made of elastic and wear-resistant material, preferably rubber, which has good elasticity and wear resistance, and has the ability to recover quickly when deformed by external force.

[0051] Furthermore, an annular second groove 2310 is provided on the inner wall of the damping member 2300, and a boss 2211 adapted to the second groove is provided at a position relative to the movable part 2210 of the movable member and the second groove 2310 of the damping member. The boss 2211 is a circular ring structure surrounding the outer wall of the movable part 2210, and the boss 2211 is embedded in the second groove 2310 to further prevent the damping member 2300 from sliding on the movable part 2210.

[0052] Furthermore, an annular groove is provided on the outer side surface of the damping member 2300, and the size and number of the annular groove are set as required to reduce weight, reduce friction, buffer rubber deformation, and reduce pressing force.

[0053] Furthermore, a boss is provided at the upper end of the movable part 2210, and the boss is a circular ring structure around the outer wall of the movable part 2210, and the diameter of the boss is slightly larger than the inner diameter of the damping member 2300, which can not only allow the damping member 2300 to pass through the boss, but also further prevent the damping member 2300 from sliding toward the positioning part 2230, so that it does not move to the positioning part 2230.

A track groove 2610 is arranged on the side of the second fixing member 2600. The track groove 2610 is a vertical strip-shaped opening. The number of the track groove 2610 can be one or two symmetrical tracks to balance the weight of the left and right sides of the second fixing member 2600. Fig. 9 As shown, the second fixing seat 3220 is set on the two side surfaces of the track groove 2610 close to the bottom end of the second fixing member 2600. The second fixing seat 3220 is two circular holes that pass through the second fixing member 2600. The push rod 3300 is placed in the middle of the two circular holes of the second fixing seat 3220. The push rod 3300 is connected to the second fixing seat 3220 through a pin shaft.

[0055] Furthermore, in order to reduce the size of the housing 1000, the side of the housing 1000 away from the push rod can be as close as possible to the outer side of the second fixing member 2600, so that the overall size of the entire device is smaller and more convenient to fix.

[0056] The push rod 3300 can rotate around the second fixing seat 3220. Fig.11 As shown, the push rod 3300 is an L-shaped structure. Preferably, the end of the push rod 3300 connected to the connecting rod 3100 is a straight plate type, and the end of the push rod 3300 away from the connecting rod 3100 is an arc-shaped plate structure that is wide at the top and narrow at the bottom. The push rod 3300 and the connecting rod 3100 are connected by a pin shaft so that the push rod 3300 and the connecting rod 3100 can move relative to each other.

[0057] Further, such as Fig.11 As shown, one end of the push rod 3300 connected to the connecting rod 3100 is a U-shaped groove structure, and the width of the middle opening of the U-shaped groove is slightly larger than the thickness of the connecting rod 3100, so that the connecting rod 3100 can be inserted into the middle opening of the U-shaped groove and fixed by a pin shaft.

[0058] Furthermore, one end of the push rod 3300 away from the connecting rod 3100 is configured to be pointed, so that when the push rod 3300 is pressed, a more realistic pricking sensation can be produced on the skin, thereby improving the effectiveness of the blind test.

[0059] Furthermore, the length of the push rod 3300 is set so that the tip of the push rod can touch the skin when it is close to its lowest position, so that the depth of the push rod 3300 pressing the skin can be increased by continuing to press the pressing member 2400 downward to adjust the pressing force.

[0060] Furthermore, in order to reduce the overall height of the auxiliary device, the length of the movable part 2200 is set as follows: the pressing part 2400 is pulled upward to move the movable part 2200 upward. When the push rod 3300 is rotated upward to the highest position, the lower end surface of the positioning portion 2230 is slightly lower than the upper surface of the shell 1000, so that the retaining member 2700 can be stuck in the lowest first groove 2232; the pressing part 2400 is pressed downward to move downward, and the movable part 2200 moves downward accordingly, thereby driving the push rod 3300 to rotate downward. When the push rod 3300 is rotated downward to the lowest point, the upper end surface of the positioning portion 2230 is slightly higher than the upper surface of the shell 1000, so that the retaining member 2700 can be stuck in the uppermost first groove 2232, which will make the height of the movable part 2200 the shortest, thereby reducing the overall height of the device.

[0061] When the experimental group members performed acupuncture, they pulled the pressing piece 2400 upward to move the movable piece 2200 upward, and the movable piece 2200 drove the push rod 3300 to rotate upward through the connecting rod 3100. When the movable piece 2200 was pulled to the top, that is, when the upper surface of the damping piece 2300 was close to the upper surface of the shell 1000, the push rod 3300 would rotate to the highest point, and the push rod 3300 would be kept in the highest position through the damping effect of the damping piece 2300 and the snap-in retention of the retaining piece 2700, thereby reserving space for the acupuncture needle to facilitate acupuncture.

[0062] Furthermore, scale lines are provided on the outer surface of the housing 1000 and the outer surface of the cylinder in the middle of the positioning portion 2230 to facilitate reference for calculating the needle insertion length.

[0063] When the control group performs acupuncture, the pressing member 2400 is pressed downward to move the movable member 2200 downward. The movable member 2200 drives the push rod 3300 to rotate downward through the connecting rod 3100. When the push rod 3300 touches the subject's skin, the bottom end of the push rod 3300 will exert pressure on the subject's skin. The pressing of the tip at the bottom end of the push rod 3300 will make the subject feel a more realistic acupuncture sensation, giving the subject an illusion of acupuncture, thereby achieving a blind method. The pressing force can be adjusted by continuously pressing the pressing member 2400, that is, adjusting the relative position between the push rod 3300 and the subject's skin, so that the pressing force can be adjusted. After setting a suitable pressing force, the retaining member 2700 is rotated, and the semicircular ring plate of the retaining member 2700 is inserted into the first groove 2232 of the positioning portion, so that the push rod 3300 is kept in the set position to keep the pressing force constant.

[0064] Furthermore, the control group can use acupuncture needles that are shorter than those of the experimental group, so that the length of the exposed part of the acupuncture needle in the experimental group after acupuncture is roughly the same as that of the exposed part in the control group, which is not easy to break the blind and ensures the effectiveness of the blind experiment.

[0065] Furthermore, an isolation component 5000 may be optionally provided in the housing 1000 to separate the acupuncture needle from the subject's skin, thereby preventing the acupuncture needle from accidentally falling off and injuring the skin during a control experiment. Although the clamp 2500 can firmly clamp the acupuncture needle, an additional layer of protection is provided to prevent accidents.

[0066] like Figure 1 As shown, the isolation assembly 5000 is disposed in the housing 1000, near the bottom end of the housing 1000, and the isolation assembly 5000 includes a spacer 5100 and a third groove 5200. Figure 2As shown, the third groove 5200 is an annular groove extending from the inner wall to the center along the inner wall of the shell, the upper and lower sides of the third groove 5200 are parallel to the bottom surface of the shell 1000, the third groove 5200 is preferably a U-shaped groove, and the third groove 5200 and the shell 1000 are preferably an integrally formed structure. The septum 5100 is placed in the third groove 5200, and the shape and size of the septum 5100 and the third groove 5200 are adapted to ensure that the septum 5100 is not easy to fall off from the third groove 5200. The septum 5100 is preferably a circular sheet, and the material of the septum 5100 is an elastic material, which can be rubber, such as butyl rubber, silicone rubber, chloroprene rubber, etc., preferably polyisoprene rubber, which has high elasticity, low deformation, high tear strength, no shavings during puncture, and is easy for the acupuncture needle to pass through during acupuncture in the experimental group, and is non-toxic, tasteless, colorless and transparent.

[0067] Furthermore, the thickness of the spacer 5100 is preferably no more than 2 mm, and the vertical distance between the bottom surface of the spacer 5100 and the bottom surface of the shell is preferably no more than 1 mm, so that even when the push rod 3300 presses the skin through the spacer 5100, it can give people a real acupuncture sensation, thereby ensuring the effectiveness of the blind experiment.

[0068] In summary, for the subjects in the control group, due to the pressing of the pointed part at the bottom end of the push rod 3300, the skin can produce a more realistic acupuncture sensation, and the distance between the push rod 3300 and the subject's skin can be adjusted by pushing and pulling the pressing member 2400 to adjust the pressing force, without the need for a fake needle, and the acupuncture needle can be fixed in the clamp 2500. Even if an accident occurs and the acupuncture needle accidentally falls off, the isolation component 5000 can be used to isolate the acupuncture needle from the subject's skin, thereby providing double protection. Therefore, the subjects cannot tell the difference in terms of feeling and appearance, thereby achieving the test purpose of the blind experiment.

[0069] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. Various adjustments or changes may be made to the exemplary embodiments of the present specification without departing from the scope or spirit of the present invention. The scope of the claims should be based on the broadest interpretation to cover all modifications and equivalent structures and functions.
