Description

Technical Field

[0001] The invention relates to the technical field of acupuncture training models, in particular to a traditional Chinese medicine acupuncture training model. Background Art

[0002] The TCM acupuncture training model is a medical model that marks the main meridians and acupoints of the human body. It is mainly used for the teaching, training and assessment of TCM acupuncture. There are many types of TCM acupuncture training models, including human acupuncture models (whole body), head acupuncture models, ear acupuncture models, hand acupuncture models and foot acupuncture models.

[0003] When medical students are trained with acupuncture models, they can intuitively understand the distribution of meridians and acupoints in the human body, and train their ability to locate acupoints, needle insertion accuracy, and finger strength. However, acupuncture models are usually made of plastic, silicone, or other synthetic materials. When medical students are trained in acupuncture, the needle insertion model cannot provide feedback when the needle is inserted into the acupoint, such as the feeling of Qi, compared to real acupuncturists. Therefore, medical students can only practice the depth of the needle according to the depth standard of the needle. This depth standard is generally a measure to avoid serious harm to patients when beginners lack the sense of Qi.

[0004] However, in acupuncture, it is important to "shallow in summer and spring, deep in autumn and winter", that is, when acupuncture is performed in different seasons, the depth of acupuncture should be different due to the differences in the circulation of qi and blood in the human body and the external environment. In ancient books such as "Suwen·Acupuncture Essentials" and "Lingshu·Nishun Feishou", there are also descriptions of determining the depth of acupuncture according to the patient's constitution (such as deep acupuncture for strong and healthy people with full blood and qi, shallow acupuncture for thin people with thin skin and less color, and shallow acupuncture for infants with fragile flesh and less blood). As a result, although medical students can skillfully control the acupuncture technique and control the acupuncture depth according to the standard through the model, due to the different individual constitutions of patients, the standard acupuncture depth will not cause harm to the patients, but it is also easy to have no effect or poor acupuncture effect. After training on the acupuncture model, medical students will also practice acupuncture and lifting, inserting and twisting on their own arms to experience and understand the acupoint reactions in the real acupuncture process, and master the sense of qi when the acupuncture needle is inserted into the acupoint. Improper operation is prone to infection. For this reason, we propose a Chinese medicine acupuncture training model. Summary of the invention

[0005] The purpose of the present invention is to provide a traditional Chinese medicine acupuncture training model to solve the problem that individual physiques of patients are different as mentioned in the above background technology. Although the standard needling depth will not cause harm to the patient, it is also easy to have no effect or poor acupuncture effect. After training on the acupuncture model, medical students will also practice needling and lifting, inserting and twisting on their own arms, experience and understand the acupoint reactions in the real acupuncture process, and master the feeling of qi when the filiform needle is inserted into the acupoint. Improper operation can easily lead to infection problems.

[0020] When the present application is in use, medical students train their ability to locate acupuncture points through the human meridian lines and acupuncture points marked on the arm model. When medical students use filiform needles for acupuncture training, muscles of different firmness are simulated by a muscle simulation mechanism according to the training needs of the medical students, thereby simulating the effect of muscles of different firmness on filiform needle puncture when acupuncture is performed on patients with different physiques such as obesity or strong body in reality, thereby assisting medical students in training their finger strength.

[0021] After the medical students insert needles at the puncture epidermis position on the surface of the arm model, the acupuncture depth detection mechanism is set to detect the insertion depth and insertion angle of the medical students' acupuncture. The acupuncture depth detection mechanism determines whether the medical students' acupuncture meets the training requirements based on the detection data. If the insertion depth and insertion angle of the acupuncture needle meet the training requirements, the air-sensing simulation mechanism simulates the muscle contraction reaction when the medical students control the lifting, insertion and twisting of the acupuncture needle; if at least one of the insertion depth and insertion angle of the acupuncture needle does not meet the training requirements, the air-sensing simulation mechanism does not simulate the muscle contraction reaction when the medical students control the lifting, insertion and twisting of the acupuncture needle, thereby training the medical students' needle insertion accuracy, and when the medical students control the lifting, insertion and twisting of the acupuncture needle, the air-sensing simulation mechanism contracts regularly to simulate the local muscle contraction reaction of the acupoint when the air is obtained, to assist the medical students in experiencing the feeling of obtaining air during acupuncture, so that the medical students can practice acupuncture in a situation close to reality and improve their acupuncture skills.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] See also Figures 1 to 8The present invention provides a technical solution: a traditional Chinese medicine acupuncture training model, comprising an arm model 1; also comprising a puncture epidermis 2; a muscle simulation mechanism 3, the muscle simulation mechanism 3 is located below the puncture epidermis 2, and the muscle simulation mechanism 3 simulates muscles of different firmness according to the training needs of medical students; an acupuncture depth detection mechanism 4, the acupuncture depth detection mechanism 4 is located on the surface of the puncture epidermis 2, and the acupuncture depth detection mechanism 4 detects the insertion depth and insertion angle of the fine needle during acupuncture by medical students; an air-sensing simulation mechanism 5, the air-sensing simulation mechanism 5 is located below the muscle simulation mechanism 3, when the acupuncture depth detection mechanism 4 detects that the insertion depth and insertion angle of the fine needle during acupuncture by medical students meet the training requirements, the air-sensing simulation mechanism 5 simulates the muscle contraction reaction when the medical students control the lifting, insertion and twisting of the fine needle; when the acupuncture depth detection mechanism 4 detects that at least one of the insertion depth and insertion angle of the fine needle during acupuncture by medical students does not meet the training requirements, the air-sensing simulation mechanism 5 does not simulate the muscle contraction reaction when the medical students control the lifting, insertion and twisting of the fine needle.

[0034] When in use, medical students train their ability to locate acupuncture points through the human meridian lines and acupuncture points marked on the arm model 1. When medical students use fine needles for acupuncture training, muscles of different firmness are simulated through the muscle simulation mechanism 3 according to the training needs of the medical students, thereby simulating the influence of muscles of different firmness on fine needle puncture when acupuncture is performed on patients with different physiques such as obesity or strong body in reality, and assisting medical students in training finger strength.

[0035] After the medical student inserts the needle at the puncture epidermis 2 position on the surface of the arm model 1, the acupuncture depth detection mechanism 4 is set to detect the acupuncture depth and the insertion angle of the fine needle during acupuncture. The acupuncture depth detection mechanism 4 determines whether the medical student's acupuncture meets the training requirements based on the detection data. If the fine needle insertion depth and the insertion angle meet the training requirements, the air-sensing simulation mechanism 5 simulates the muscle contraction reaction when the medical student controls the fine needle to lift, insert and twist. The air-sensing simulation mechanism 5 contracts regularly to simulate the local muscle contraction reaction of the acupoint when the air is obtained, so as to assist the medical student to experience the feeling of getting air during acupuncture, so that the medical student can practice acupuncture in a situation close to reality and improve the acupuncture skills. If at least one of the fine needle insertion depth and the insertion angle does not meet the training requirements, the air-sensing simulation mechanism 5 does not simulate the muscle contraction reaction when the medical student controls the fine needle to lift, insert and twist, thereby training the medical student's needle insertion accuracy.

[0036] The muscle simulation mechanism 3 includes a silicone block 30, which is fixedly connected to the bottom of the punctured epidermis 2, and a squeezing plate 31 is abutted against the side of the silicone block 30. An electric telescopic rod 32 is fixedly connected to the outer side of the squeezing plate 31, and the electric telescopic rod 32 is installed on the inner wall of the arm model 1.

[0037] Since the silicone block 30 is made of silicone, silicone is a polymer material with excellent elasticity. It can deform when subjected to external force and return to its original shape after the external force is removed. When the silicone is subjected to continuous extrusion or pressure, its internal structure and molecular arrangement will change. Specifically, when the electric telescopic rod 32 is extended, the electric telescopic rod 32 pushes the extrusion plate 31 to squeeze the silicone block 30. When the silicone block 30 is squeezed, its internal molecular chains will be stretched and compressed by external force, resulting in enhanced interaction force between the molecular chains. This enhanced interaction force will make the molecules inside the silicone more densely arranged, thereby showing a compact characteristic. By controlling the telescopic length of the electric telescopic rod 32, the silicone block 30 can be controlled to show different degrees of compactness, thereby simulating the muscle tightness of patients with different physiques in actual situations and training the finger strength of medical students for acupuncture.

[0038] The acupuncture depth detection mechanism 4 includes an adjustment block 40, which is slidably connected to the surface of the arm model 1. A pull-wire displacement sensor 41 and a laser ranging sensor 42 are installed on the outside of the adjustment block 40. A controller 43 is installed on the outside of the arm model 1. The pull-wire displacement sensor 41 and the laser ranging sensor 42 are respectively connected to the controller 43.

[0039] The controller 43 is installed on the surface of the arm model 1. The controller 43 is composed of a display screen and a processing module. Medical students select test items through the display screen of the controller 43. The processing module of the controller 43 sends control instructions to components such as the electric telescopic rod 32, the rotating motor 57, the servo motor 513 and the electromagnet 521. The electric telescopic rod 32 is connected to the controller 43. Medical students control the extension of the electric telescopic rod 32 through the controller 43, so that the silicone block 30 exhibits different degrees of firmness.

[0040] The pull-wire displacement sensor 41 and the laser distance sensor 42 are mature existing technologies in the market. The laser distance sensor 42 has two sets of infrared transmitting ends and receiving ends, so as to measure the distance between the laser distance sensor 42 and the pull rope and the distance between the laser distance sensor 42 and the millimeter needle. The principle of the pull-wire displacement sensor 41 is mainly based on the process of converting physical phenomena and mechanical motion into electrical signals. Its sensor is usually installed in a fixed position, and the pull rope can be pulled. When the pull rope is extended or contracted, the threaded hub will drive the encoder to rotate. The rotation angle of the encoder is proportional to the extended length of the pull rope. The encoder calculates the extended length of the pull rope according to the rotation angle, and converts it into an electrical signal output to achieve the measurement of the pull-wire displacement.

[0041] When detecting the insertion depth of the fine needle, the medical student controls the adjustment block 40 to slide on the surface of the arm model 1. The adjustment block 40 drives the pull-wire displacement sensor 41 and the laser ranging sensor 42 to move, so that the outlet of the pull-wire displacement sensor 41 is coplanar with the fine needle. After the two are coplanar, the medical student pulls the pull rope of the pull-wire displacement sensor 41 and makes the pull rope reach the end position of the fine needle.

[0042] At this time, the pull-wire displacement sensor 41 will measure the distance between the pull-wire displacement sensor 41 and the end of the fine needle, and the length of this distance is a. The distance between the laser distance sensor 42 and the pull-wire displacement sensor 41 is fixed, and the length of this distance is b. When the pull rope reaches the end of the fine needle, the laser distance sensor 42 can measure the distance between the laser distance sensor 42 and the pull rope, and the length of this distance is c. When the pull rope reaches the end of the fine needle, the angle between the pull rope and the surface of the adjustment block 40 is d.

[0043] Then tan(d) = c / b. Since the angle of d is between 0 and 90°, the value of d can be uniquely determined.

[0044] The distance between the laser distance sensor 42 and the needle can be measured by the laser distance sensor 42, and the length of this distance is set as e, and the distance between the pull rope distance sensor and the needle is set as m;

[0045] Then m=e+b;

[0046] In the triangle system composed of the pull rope, part of the needle and the laser distance sensor 42, let the length of the part of the needle be L;

[0047] According to the formula of the cosine theorem, L^2=a^2+m^2-2a×m×cos(d), thus obtaining the value of L;

[0048] Since the wire displacement sensor 41 and the laser distance sensor 42 are both located on the surface of the adjustment block 40, the distance between the wire displacement sensor 41 and the laser distance sensor 42 and the surface of the arm model 1 is a fixed value, and this fixed value is known during the design. Let this fixed value be f, and let the angle between the arm model 1 and the needle be h;

[0049] Then h = 90°-d;

[0050] Let the length of the needle between the arm model 1 and the top plane of the adjustment block 40 be k;

[0051] Then k = f / sin(h);

[0052] Therefore, the length of the filiform needle exposed outside the arm model 1 is L+k, and the length of the filiform needle inserted into the arm model 1 can be obtained through the standard length of the filiform needle - (L+k).

[0053] The air-sensing simulation mechanism 5 includes a plurality of silicone blocks 50, which are located below the silicone block 30 and are stacked. An adjusting member 51 is provided on the inner wall of the arm model 1 for adjusting the firmness of the silicone block 50 according to training requirements.

[0054] When in use, the medical student selects the depth of the acupuncture point and the insertion angle of the fine needle through the controller 43, and controls the extension of the electric telescopic rod 32 through the controller 43, so as to adjust the firmness of the silicone block 30. After the setting is completed, the medical student uses the fine needle to puncture the epidermis 2. After the fine needle is inserted into the arm model 1, the medical student moves the adjustment block 40 to make the outlet of the pull-wire displacement sensor 41 coplanar with the fine needle, and then pulls the pull rope at the pull-wire displacement sensor 41, and measures the distance between the pull-wire displacement sensor 41 and the fine needle end through the pull rope, and the laser distance sensor 42 measures the distance between the laser distance sensor 42 and the pull rope respectively. The distance between the laser ranging sensor 42 and the fine needle, and the measured information is transmitted to the controller 43. The controller 43 calculates the insertion length of the fine needle and the angle between the fine needle and the arm model 1 according to the above principle, and compares the calculated information with the acupoint position information set during training. Because the depths of acupuncture channels in the human body are different, the techniques for inserting different acupoints are also different. For example, in straight insertion, the needle body is inserted perpendicularly to the skin surface at 90°; in oblique insertion, the needle body is inserted obliquely at about 45° to the skin surface. Therefore, by detecting the insertion depth and insertion angle of the fine needle, it is determined whether the medical student has inserted the fine needle into the target acupoint during acupuncture.

[0055] If the insertion depth and insertion angle of the fine needle meet the training requirements, the adjustment member 51 periodically squeezes the silicone block 2 50 at the corresponding position when the medical student controls the lifting, insertion and twisting of the fine needle. Since the medical student lifts and inserts the needle 60 times per minute, the adjustment member 51 also squeezes the silicone block 2 50 at a frequency of 60 times per minute, thereby simulating a muscle contraction reaction, providing a muscle contraction reaction for the medical student when inserting the needle into the correct acupuncture point with the correct technique, and simulating the feeling of tightness when the medical student lifts, inserts, and turns the needle when inserting the real acupuncture point.

[0056] If at least one of the needle insertion depth and insertion angle does not meet the training requirements, the adjustment member 51 will not work, so that even if the medical students control the needle to lift, insert and twist, no feedback will be provided to remind the medical students that the operation has failed, thereby standardizing the acupuncture techniques and accuracy of the medical students.

[0057] The adjusting member 51 includes an extrusion plate 52 abutting against the outer side of the silicone block 50, and an inclined end 58 is provided on the side of the silicone block 50 close to the extrusion plate 52, a push plate 53 is provided on the outer side of the extrusion plate 52, a rotating member 54 for adjusting the inclination angle of the extrusion plate 52 is provided between the push plate 53 and the extrusion plate 52, and a driving member 55 for driving multiple push plates 53 to reciprocate is provided on the outer side of the push plate 53.

[0058] After the medical student inserts the fine needle into the arm model 1, the controller 43 receives the information measured by the pull-wire displacement sensor 41 and the laser ranging sensor 42, and compares the detected information with the preset training requirements. If it meets the standards, the rotating member 54 works according to the training requirements. If the training is straight puncture, it does not work. If the training is oblique puncture, the rotating member 54 drives the extrusion plate 2 52 to rotate to 45 degrees, so that the inclined extrusion plate 2 52 is squeezed with the oblique end 58 of the silicone block 2 50 at the corresponding position, so that when the driving member 55 drives the extrusion plate 2 52 to squeeze the silicone block 2 50 at a frequency of 60 times per minute, the tightening force inside the silicone block 2 50 is also perpendicular to the fine needle, avoiding affecting the medical student's feeling when controlling the lifting, insertion and twisting of the fine needle; if it does not meet the training requirements, the driving member 55 and the rotating member 54 do not work.

[0059] The rotating member 54 includes a rotating seat 56 fixedly connected to one end of the extrusion plate 52 away from the silicone block 50 . The rotating seat 56 is rotatably connected to the push plate 53 . A rotating motor 57 is installed on the surface of the push plate 53 . The output end of the rotating motor 57 is fixed to the rotating seat 56 .

[0060] The controller 43 compares the detected information with the preset training requirements of the medical students. If the training is oblique needle, the rotating motor 57 installed on the surface of the push plate 53 will work, and the output end of the rotating motor 57 will drive the rotating seat 56 to rotate. The rotating seat 56 and the push plate 53 rotate relative to each other, and the rotating seat 56 drives the squeezing plate 2 52 to rotate to 45°, so that when the silicone block 2 50 is squeezed, the squeezing plate 2 52 and the oblique end 58 of the silicone block 2 50 are squeezed against each other, so that the silicone tissue around the fine needle produces a tightening force perpendicular to the surface of the fine needle; if the training is straight needle or the medical student's acupuncture technique does not meet the training requirements, the rotating motor 57 will not work.

[0061] The driving member 55 includes a connecting rod 59 rotatably connected to the push plate 53, a turntable 510 is provided at one end of the connecting rod 59 away from the push plate 53, the turntable 510 is rotatably connected to the connecting rod 59, a transmission gear 511 is provided on the outer side of the turntable 510, and a plurality of transmission gears 511 are meshed with toothed belts 512 on the outer sides, a servo motor 513 is fixedly connected to the outer side of one of the transmission gears 511, and the servo motor 513 is installed on the inner wall of the arm model 1, and a connecting member 514 is provided between the turntable 510 and the transmission gear 511.

[0062] According to the training acupuncture point requirements of medical students, the connecting piece 514 at the corresponding position works, and the connecting piece 514 works so that the transmission gears 511 and the turntable 510 on both sides of the connecting piece 514 can rotate synchronously. When simulating the contraction of the acupuncture point muscles, the servo motor 513 drives the transmission gear 511 fixed to its output shaft to rotate, and this transmission gear 511 drives the remaining transmission gears 511 to rotate through the toothed belt 512. The transmission gear 511 drives the turntable 510 to rotate through the connecting piece 514, and the turntable 510 drives the connecting rod 59 to swing. While the connecting rod 59 and the push plate 53 rotate relative to each other, the push plate 53 is driven to reciprocate on the inner wall of the arm model 1, so that the squeezing plate 2 52 squeezes the silicone block 2 50 at a frequency of 60 times per minute.

[0063] The connecting member 514 includes a docking rod 515 fixedly connected to the transmission gear 511, a connecting block 516 is slidably connected to the inner wall of the docking rod 515, an iron sheet 517 is fixedly connected to the end of the connecting block 516, the cross-section of the connecting block 516 is cross-shaped, the connecting block 516 is slidably connected to the inner wall of the docking rod 515, a return spring 518 is fixedly connected to the outer side of the connecting block 516, the return spring 518 is fixed to the inner wall of the docking rod 515, a fixing column 519 is fixedly connected to the inner wall of the turntable 510, a docking groove 520 is opened on the fixing column 519 near one end of the connecting block 516, an electromagnet 521 is installed on the inner wall of the docking groove 520, a battery pack 522 is installed on the inner wall of the fixing column 519, and the battery pack 522 is connected to the electromagnet 521.

[0064] The battery pack 522 is composed of a plurality of button batteries to power the electromagnet 521. When the electromagnet 521 is energized, a magnetic field is generated. The electromagnet 521 attracts the iron sheet 517 at the end of the connecting block 516 through the magnetic field. The iron sheet 517 drives the connecting block 516 to slide from the inner wall of the docking rod 515 to the docking groove 520 on the inner wall of the fixed column 519. The connecting block 516 moves the stretched reset spring 518. Since the cross-section of the connecting block 516 is cross-shaped and the cross-section of the docking groove 520 is also cross-shaped, after the connecting block 516 is inserted into the docking groove 520, when the transmission gear 511 rotates, the docking rod 515 and the fixed column 519 rotate synchronously through the connecting block 516 to cooperate with the rotation of the turntable 510. When acupuncture is completed, the electromagnet 521 is powered off and no longer attracts the iron sheet 517. At this time, the reset spring 518 in a stretched state drives the connecting block 516 to reset, and the turntable 510 and the transmission gear 511 no longer rotate synchronously.

What is different from the first embodiment is that other areas of the arm model 1 are also provided with epidermal puncture 2, muscle simulation mechanism 3, acupuncture depth detection mechanism 4 and air sensation simulation mechanism 5 to assist in training medical students to perform acupuncture on different positions of the patient's arm and improve the practice effect.
