Description

Technical Field

[0001] This invention belongs to the field of pulse diagnosis technology, and specifically relates to a pulse model for traditional Chinese medicine diagnosis. Background Technology

[0002] Pulse diagnosis is one of the core skills of the four diagnostic methods in Traditional Chinese Medicine (TCM) (inspection, auscultation and olfaction, inquiry, and palpation), and its accuracy directly affects the level of clinical diagnosis in TCM. However, pulse diagnosis teaching has long faced the dilemma of "understanding in the mind but not in the fingertips": there are many types of pulses (TCM classics summarize them into twenty-eight standard pulse types), each with an abstract feel and significant individual differences; even the same pulse type can manifest differently in different patients, making it difficult for beginners to master all pulse characteristics through limited clinical practice. Traditional teaching relies on repeated pulse taking of real patients under the master-apprentice model, but the pulse characteristics of real patients cannot be stably reproduced, making it difficult to teach in batches and conduct standardized assessments.

[0003] To improve this situation, bionic pulse diagnosis teaching models have emerged in recent years. However, existing pulse diagnosis models have many technical shortcomings, severely limiting the effectiveness of teaching: The coverage of pulse patterns is extremely limited. Most commercially available pulse diagnosis models can only simulate a few common pulse patterns such as floating, deep, slow, and rapid, failing to fully cover the 28 standard pulse patterns in traditional Chinese medicine, let alone simulate complex or rare pulse patterns such as hurried, knotted, intermittent, rapid, scattered, hollow, leathery, and firm. Students can only be exposed to a portion of pulse patterns during their studies, resulting in a significant deficiency in pulse diagnosis identification skills upon graduation.

[0004] Furthermore, the biomimetic pulse structure is too simplistic, resulting in poor tactile feedback. Existing models mostly use silicone tubes with uniform diameter, wall thickness, and hardness, failing to differentiate the tactile feel of varied pulse shapes, such as the broad and surging of a surging pulse, the thin, straight, and taut of a wiry pulse, the soft and weak of a soothing pulse, and the extremely thin and soft of a micropulse. When students take a pulse, they perceive "all pulses are the same," making it impossible to develop a differentiated tactile memory for different pulse characteristics.

[0005] Meanwhile, there is a lack of structured and adjustable simulation devices for pulse position, shape, and momentum. The clinical characteristics of a real pulse involve multiple spatial dimensions, including pulse depth (superficial, deep, hidden), pulse width (bounding, thin), pulse length (long, short), and pulse position (hollow, full). Existing models typically differentiate pulse types only by adjusting the pulse frequency and amplitude, failing to distinguish different pulse types based on geometric features such as pulse position, shape, and momentum. This results in indistinct tactile differences between superficial and deep pulses, and difficulty in differentiating between long and short pulses. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pulse model for TCM diagnosis.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a pulse model for traditional Chinese medicine diagnosis. This includes a simulated human hand model and a pulse shaping device, a pulse driving device, and a pulse sensing device built into the simulated human hand model. The pulse driving device includes a rotatable and adjustable pulse wave integrated roller, a simulated heart ejection drive assembly located inside the pulse wave integrated roller, an automatic opening and closing device between the heart and blood vessels, and an adjustment system for adjusting the size, height, depth, and width of the groove. The pulse forming device includes a simulated heart blood supply system located inside the pulse image integrated roller, a pulse image mounting groove composed of multiple adjustable U-shaped component units of varying sizes, heights, depths, and widths, and bionic blood vessels of varying thicknesses, lengths, diameters, hardness, and wall thicknesses. The number of pulse pattern mounting grooves is 28, each groove is evenly distributed in a circle on the outer surface of the pulse pattern integrated roller. Each groove corresponds to one of the 28 standard pulse patterns in Traditional Chinese Medicine. The 28 standard pulse patterns are: floating pulse, deep pulse, slow pulse, rapid pulse, slippery pulse, hesitant pulse, weak pulse, strong pulse, long pulse, short pulse, surging pulse, faint pulse, tense pulse, slow pulse, wiry pulse, hollow pulse, leathery pulse, firm pulse, soft pulse, weak pulse, scattered pulse, thready pulse, hidden pulse, arterial pulse, hurried pulse, knotted pulse, intermittent pulse, and rapid pulse. The pulse mounting grooves are each provided with different mounting structures for adapting to the corresponding pulse, and each mounting structure is assembled and used with multiple bionic blood vessels. The mounting structure, through the differentiated pulse mounting groove structure and the bionic blood vessels, simulates the physiological characteristics of human pulse, such as pulse position, pulse shape, pulse strength, smoothness and roughness, weakness and fullness, softness and hardness. The simulated human hand model includes an arm skeletal system, simulated arm flesh and skin tissue, and electrical equipment to ensure the normal operation of the model.

[0008] Preferably, the 28 pulse mounting grooves are differentiated and adjustable through four dimensions: width, depth, length, and height, to accurately correspond to different pulse characteristics.

[0009] Preferably, the simulated heart blood supply drive assembly is equipped with a variable frequency ejection module and a branch automatic opening and closing control valve group. The variable frequency ejection module can precisely control the heart's ejection frequency per minute and the intensity of a single ejection. The ejection frequency covers all rhythm ranges of slow pulse, moderate pulse, rapid pulse, fast pulse, knotted pulse, and intermittent pulse, and the ejection intensity is adjustable in multiple levels. The branch automatic opening and closing control valve group is independently matched with the 28 pulse mounting grooves corresponding to the bionic blood vessels, and opens and closes synchronously with the rotation and positioning of the pulse integrated roller, only targeting the bionic pulse in the cun, guan, and chi pulse diagnosis area at the current position. The bionic blood vessel automatically opens the blood supply pathway, while the remaining inactive blood vessels automatically close and cut off the flow, achieving precise and independent blood supply from a single blood vessel. The simulated heart blood supply drive assembly has an ejection chamber and a return chamber inside. A movable piston is set between the ejection chamber and the return chamber. A first one-way check valve is installed at the bottom of the piston. A second one-way check valve is installed at the bleeding port of the ejection chamber, and a third one-way check valve is installed at the inlet of the return chamber. The first, second, and third one-way check valves are all used to control the blood flow direction and prevent blood from flowing backward.

[0010] Preferably, the pulse pattern mounting groove is a modular adjustable structure, and each pulse pattern mounting groove is composed of several sets of independently adjustable U-shaped component units spliced ​​together; each U-shaped component unit is equipped with an independent fine-tuning component, which can adjust the opening and closing size, installation height, groove depth, and effective extension length of the U-shaped component unit respectively; through the coordinated fine-tuning of multiple sets of U-shaped component units, the fixed groove shape of twenty-eight standard pulse patterns can be accurately defined, and the parameters can be customized to simulate various combined pulse patterns, variant pulse patterns, and pathological pulse patterns.

[0011] Preferably, the bionic blood vessel is a hollow silicone tube structure with a customized structure that adapts its hardness, extensibility, lumen size, and wall thickness to fit the 28 pulse mounting grooves. The diameter, wall thickness, and silicone material hardness of the bionic blood vessel are specifically designed according to the vascular pressure, wall tension, and blood flow pulsation characteristics of the corresponding pulse.

[0012] Preferably, the bionic blood vessel has a hollow flow structure inside, which can be connected to an external pressure control device; the external pressure control device inputs controllable air pressure or hydraulic pressure into the bionic blood vessel to simulate the pulsating pressure and blood flow impact force of the human pulse.

[0013] Preferably, the pulse image integration roller is an integrated rotating structure, installed between the cun, guan, and chi muscles of the simulated human hand model, and equipped with a positioning and locking structure; 28 pulse image mounting grooves are evenly distributed in a ring array on the outer circular surface of the pulse image integration roller. By manually or automatically rotating the pulse image integration roller, any target pulse image mounting groove can be aligned with the cun, guan, and chi pulse diagnosis position of the simulated human hand model, realizing rapid switching of 28 standard pulse images.

[0014] Preferably, each of the U-shaped component units has a fine-tuning component with a precise scale marking, which corresponds to the width, depth, height, and length of the groove. The precise quantitative adjustment of various parameters of the pulse can be achieved through the scale marking.

[0015] Preferably, the simulated human hand model strictly replicates the anatomical structure of the pulse diagnosis area of ​​the human wrist. The pulse diagnosis area is made of flexible simulated silicone material, and the skin thickness and softness conform to the real characteristics of human wrist skin. The muscle tissue is made of soft and non-adhesive silicone particles, allowing the pulse integrated roller to rotate flexibly inside the muscle tissue. The bionic blood vessel position corresponding to the pulse integrated roller is precisely aligned with the standard finger placement positions of the human wrist's cun, guan, and chi positions, fully matching the clinical pulse diagnosis operation standards of traditional Chinese medicine's superficial, middle, and deep palpation.

[0016] Preferably, the bionic blood vessels corresponding to different pulse types are set with different elastic coefficients; among them, the bionic blood vessels corresponding to the tense pulse and the wiry pulse have high elastic tension, which accurately simulates the tactile feeling of the blood vessel being taut like a string; the bionic blood vessels corresponding to the soft pulse and the diffuse pulse have low elastic tension, which restores the pulse characteristics of the blood vessel being relaxed, soft and diffuse.

[0017] In summary, the present invention has the following beneficial effects: 1. This invention achieves full-coverage simulation of 28 standard pulse patterns in Traditional Chinese Medicine, filling a gap in the industry; the pulse pattern integrated roller has 28 independent pulse pattern mounting grooves evenly distributed on its outer circumference, each corresponding to all 28 standard pulse patterns in Traditional Chinese Medicine. Each groove is equipped with exclusive structural parameters and a matching bionic blood vessel, which completely solves the pain point that existing equipment can only simulate a few common pulse patterns and has incomplete teaching coverage, enabling students to systematically learn to identify all standard pulse patterns. 2. The present invention uses four-dimensional adjustable grooves and differentiated blood vessels to accurately replicate pulse position, pulse shape and pulse momentum. The 28 grooves are independently differentiated in four dimensions: width, depth, length and height. Combined with bionic blood vessels with different diameters, wall thicknesses, softness and hardness and elasticity coefficients, it can accurately simulate the clinical characteristics of the surging pulse, the thin and taut wiry pulse, the superficial and easily felt floating pulse, the deep and heavy pulse, the extra-local pulsation of the long pulse, and the short and infrequent pulse, which greatly improves the realism of the simulation feel. 3. This invention features a variable frequency ejection and shunt automatic blood supply system that accurately simulates rhythmic pulse patterns. The simulated cardiac blood supply drive assembly incorporates a built-in variable frequency ejection module, allowing stepless adjustment of ejection frequency (covering slow, moderate, rapid, and fast pulses) and ejection intensity (distinguishing between strong, full, and weak pulses), and setting intermittent pulsation modes for fast, knotted, and intermittent pulses. It is also equipped with a 28-channel independent automatic opening and closing control valve group, which, with the rotation of the roller, only connects to the currently positioned blood vessel, automatically cutting off flow to the others, eliminating crossflow interference, ensuring a pure pulse pattern, and accurately replicating various rhythmic pulse patterns. The unique cardiac ejection chamber-return chamber piston structure, combined with multi-stage one-way check valves, accurately simulates the entire process of cardiac contraction and diastolic filling. Combined with variable frequency drive, it can highly reproduce the hemodynamic characteristics of slow, rapid, fast, knotted, and intermittent pulse patterns, superior to traditional simple pumping methods. 4. The modular U-shaped adjustable structure of this invention supports the customization of concurrent and pathological pulses; each pulse mounting groove is composed of multiple sets of independent adjustable U-shaped component units, which, together with the scale fine-tuning component, can not only define twenty-eight standard pulses, but also freely combine the width, depth, length, height and vascular parameters to simulate various concurrent and complex pathological pulses such as floating, thin and weak, deep, wiry and tight, meeting the needs of all scenarios from basic teaching to advanced clinical training; 5. This invention features fully quantified scale adjustment, achieving standardization in pulse diagnosis teaching and skills assessment. The U-shaped component and the blood ejection frequency, intensity, and external pressure control devices are all equipped with precise scale markings, ensuring all parameters are fixed, reproducible, and quantifiable. Teachers can uniformly set assessment standards, and students can train according to standardized parameters, completely solving the problems of inconsistent feel, vague standards, and inability to quantify assessments in traditional pulse diagnosis teaching, thus promoting the standardization of TCM pulse diagnosis education. 6. This invention features a highly biomimetic human hand structure that is adapted to clinical operations, providing extremely realistic training. The simulated human hand model strictly replicates the anatomical positions of the wrist (cun, guan, chi), with skin and muscle materials conforming to the characteristics of real soft tissue. The blood vessels are precisely aligned with the finger positions for cun, guan, and chi, fully supporting a complete set of clinical diagnostic techniques, including superficial, middle, and deep palpation, lifting and pressing, single-finger placement, and three-finger simultaneous pressing. This allows students to gain a pulse diagnosis experience almost indistinguishable from that of real patients, significantly improving teaching effectiveness. Attached Figure Description

[0020] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0021] Specific embodiments of the present invention are described below with reference to the accompanying drawings: Example 1: Standard Twenty-Eight-Pulse Fixed Simulation Implementation Method The whole machine of the present invention consists of a simulated human hand model 1 and a pulse shaping device 101, a pulse driving device 102 and a pulse sensing device 103 built into the simulated human hand model 1.

[0022] The pulse drive device 102 includes a rotatable and adjustable pulse integrated roller 2, a simulated heart ejection drive assembly located inside the pulse integrated roller 2, an automatic opening and closing device between the heart and blood vessels, and an adjustment system for adjusting the size, height, depth, and width of the groove.

[0023] The pulse shaping device 101 includes a simulated heart blood supply system located inside the pulse image integrated roller 2, a pulse image mounting groove 7 composed of multiple adjustable U-shaped component units 4 with different sizes, heights, depths, and widths, and a bionic blood vessel 5 with different thicknesses, lengths, diameters, hardness, and wall thicknesses. There are 28 independently set pulse pattern mounting grooves 7, and the 28 pulse pattern mounting grooves 7 are evenly distributed in a circle on the outer surface of the pulse pattern integrated roller 2. The 28 pulse pattern mounting grooves 7 correspond one-to-one with the 28 standard pulse patterns in traditional Chinese medicine. Hongmai: It is equipped with a wide and high-section pulse installation groove 7 (groove width 12mm, depth 8mm), and a thick-diameter (inner diameter 6mm) and thick-walled (1.5mm) rigid bionic pulse tube 5 to simulate the heart blood supply drive assembly 3 to output high pressure (80-120mmHg) and high flow rate blood flow, so as to achieve a wide pulse channel and a strong pulse effect. String pulse: It is equipped with a narrow groove (3mm wide, 10mm deep) high-pressure structure, combined with a medium-fine tube diameter (3mm inner diameter) and high elastic tension bionic pulse tube 5 (Shore hardness 50A) to simulate the taut feel of a pulse like a bowstring. Floating pulse: A high-level shallow groove (2mm from the skin layer) is used, and the bionic blood vessel 5 is close to the subcutaneous tissue. It can be easily obtained by gentle palpation. Deep pulse and hidden pulse: Use a low-position deep groove (8-12mm from the skin layer), and you need to press hard to the deep layer to feel the pulse. Long pulse: The extended pulse mounting groove 7 is used (effective length 45mm, exceeding the standard cun-guan-chi range of 35mm), and the pulsation range exceeds the normal position; Short pulse: The short pulse pattern is installed in groove 7 (effective length 20mm), with a short and rapid pulse that does not reach the target position.

[0024] The variable frequency ejection module 8 of the simulated heart blood supply drive assembly 3 outputs a corresponding frequency according to the pulse rhythm: Slow pulse, bradycardia: Set to low-frequency ejection (40-60 times / minute); Rapid pulse, fast pulse: Set to high-frequency blood ejection (90-140 times / minute); Rapid pulse, knotted pulse, intermittent pulse: Set irregular rhythm and intermittent pulsation mode (such as pausing once after every 5-10 pulses).

[0025] After the pulse integrated roller 2 is rotated and positioned, the positioning locking structure 6 fixes the position. The system conducts the corresponding valve in the automatic opening and closing control valve group 9 of the current work station through mechanical contacts or Hall sensors, while the other 27 valves remain closed to ensure pure output of single pulse.

[0026] The internal structure of the simulated heart blood supply drive assembly 3 of the present invention is as follows: It has a sealed cavity, which is internally divided into an ejection chamber 301 and a return chamber 302 by a movable piston 303. The piston 303 is driven by a variable frequency ejection module 8 (such as a linear motor or electromagnet) to perform reciprocating motion. A through hole is opened at the bottom of the piston 303, and a first one-way check valve 304 is installed thereon, which only allows blood to flow from the return chamber 302 to the ejection chamber 301. The outlet end (bleeding port) of the ejection chamber 301 is connected to the main blood supply pipeline, and a second one-way check valve 305 is installed at the connection point, allowing blood to flow only from the ejection chamber 301 to the main pipeline. The inlet end (blood inlet) of the return chamber 302 is connected to the fluid supply pipeline of an external pressure regulating device 10, and a third one-way check valve 306 is installed thereon, allowing blood to flow only from the external pipeline into the return chamber 302.

[0027] During operation, piston 303 moves forward (compressing ejection chamber 301), increasing the pressure in ejection chamber 301. The second one-way check valve 305 opens, pumping blood into the bionic blood vessel 5, generating a pulsation. Simultaneously, the first one-way check valve 304 closes due to the pressure difference, preventing blood from flowing back into the return chamber 302. When piston 303 moves backward (retracts), the pressure in ejection chamber 301 decreases, the second one-way check valve 305 closes, and the first one-way check valve 304 opens, allowing blood from the return chamber 302 to enter ejection chamber 301. Simultaneously, the third one-way check valve 306 opens, allowing external blood to enter the return chamber 302 to replenish it. This cycle repeats, simulating the ejection and filling process of the heart. By adjusting the movement frequency and stroke of piston 303 (i.e., the output of the variable frequency ejection module 8), the ejection rhythm and intensity can be precisely controlled to adapt to different pulse conditions.

[0028] Example 2: Customized Adjustment Implementation of Concurrent and Pathological Pulses The pulse mounting groove 7 of this invention is composed of multiple sets of independent adjustable U-shaped component units 4 (each pulse mounting groove 7 has 3-5 U-shaped component units 4 arranged along its length). Each U-shaped component unit 4 has fine-tuning functions for opening and closing size, height, depth, and length, with an adjustment accuracy of 0.5mm.

[0029] Instructors can freely combine parameters: Set the composite parameters of "floating + thin + weak": the U-shaped component unit 4 is placed shallowly (2mm from the skin), narrowed in width (3mm), and shortened in length (25mm), and is matched with the thin-diameter (1.5mm inner diameter), thin-walled (0.5mm) low-elasticity bionic blood vessel 5, and the blood ejection intensity of the simulated heart blood supply drive assembly 3 is adjusted to a low level (30-50mmHg) to simulate the floating, thin and weak pulse of qi deficiency; Set the parameters to "deep + string + solid + tight": U-shaped component unit 4 is deep (10mm from the skin), narrow (2.5mm), and standard (35mm) in length. It is matched with a medium-fine tube diameter (2.5mm inner diameter) and a high-elasticity bionic blood vessel 5 (Shore hardness 60A). The blood ejection intensity of the simulated heart blood supply drive assembly 3 is adjusted to high (100-140mmHg), and the frequency is adjusted to normal to fast (80 times / minute) to simulate the deep, stringy, solid pulse caused by cold and dampness.

[0030] By adjusting the pressure inside the bionic blood vessel 5 (the external pressure control device 10 can output continuously adjustable pressure from 0 to 200 mmHg) and simulating the ejection frequency and intensity of the heart blood supply drive assembly 3, various common clinical complex pathological pulse patterns can be generated.

[0031] Example 3: Implementation Method of Clinical Standardized Finger Technique Training The simulated human hand model 1 of this invention uses flexible simulated silicone for the skin (thickness 1.5-2mm, Shore hardness 10A), and non-adhesive soft silicone particles (particle size 0.5-1mm) for the muscles. The pulse integrated roller 2 can rotate flexibly, and the bionic blood vessel 5 is precisely aligned with the standard points of Cun (about 15mm from the wrist crease), Guan (about 15mm from the Cun point), and Chi (about 15mm from the Guan point).

[0032] Learners can perform a full range of clinical procedures according to TCM standards: superficial palpation (light touch to the skin, pressure approximately 50g), mid-level palpation (pressing to the middle layer of muscle, pressure approximately 200g), deep palpation (pressing heavily to the deep layer, pressure approximately 500g), lifting and pressing, single-finger placement, and three-finger simultaneous pressing, etc. The equipment's structural resistance, subcutaneous depth, and pulsation transmission closely resemble the characteristics of a real wrist, achieving zero-discrepancy clinical training.

[0033] Example 4: Implementation of Quantitative Teaching and Skills Assessment All adjustment parts in this invention are equipped with precise scale markings: U-shaped component unit 4 width and narrow scale: 0-15mm, accuracy 0.5mm; U-shaped component unit 4 depth scale: 0-20mm, accuracy 0.5mm; U-shaped component unit 4: Length scale: 10-50mm, accuracy 1mm; U-shaped component unit 4 height and low scale: 0-15mm (distance from skin layer), accuracy 0.5mm; Variable frequency blood ejection module with 8 frequency scales: 30-150 times / minute, with an accuracy of 1 time / minute; Variable frequency blood ejection module with 8 intensity scales: 0-200 mmHg, accuracy 5 mmHg; External pressure control device with 10 scales: 0-200 mmHg, accuracy 5 mmHg.

[0034] Teachers can set standardized pulse parameters for assessment (e.g., "floating pulse: shallow groove 2mm, wide groove 8mm, frequency 75 times / minute, pressure 70mmHg"), and students can undergo unified practical training and assessment, thus completely solving the industry pain points of traditional pulse diagnosis teaching, such as "inconsistent teacher feel, inconsistent standards, and inability to quantify assessments".

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.

A pulse model for TCM diagnosis according to claim 4, characterized in that: Each of the U-shaped component units (4) has a fine-tuning component with a precise scale mark, and the scale mark corresponds to the width, depth, height, and length of the groove, respectively. The scale mark enables precise quantitative adjustment of various parameters of the pulse.

9. A pulse model for TCM diagnosis according to claim 1, characterized in that: The simulated hand model (1) strictly replicates the anatomical structure of the pulse diagnosis area of ​​the human wrist. The pulse diagnosis area is made of flexible simulated silicone material, and the skin thickness and softness are in line with the real characteristics of human wrist skin. The muscle tissue is made of soft and non-adhesive silicone particles, so that the pulse integrated roller (2) can rotate flexibly inside the muscle tissue. The position of the bionic blood vessel (5) corresponding to the pulse integrated roller (2) is precisely aligned with the standard finger placement position of the human wrist cun, guan and chi parts, which is completely in line with the clinical pulse diagnosis operation norms of TCM superficial, middle and deep palpation.

10. A pulse model for TCM diagnosis according to claim 5, characterized in that: Different elastic coefficients are set for the bionic blood vessels (5) corresponding to different pulse patterns; among them, the bionic blood vessels (5) corresponding to the tight pulse and the string pulse have large elastic tension, which accurately simulates the tactile feeling of the blood vessel being taut like a string; the bionic blood vessels corresponding to the soft pulse and the scattered pulse have small elastic tension, which restores the pulse pattern characteristics of the blood vessel being relaxed, soft, and having diffuse pulsation.
