Description

Technical Field

[0001] The invention relates to medical teaching equipment, in particular to a pulse monitor imitating heart dual power circulation system suitable for pulse teaching. Background Art

[0002] Pulse diagnosis is the essence of Chinese medicine and a kind of Chinese medicine culture with national characteristics. It has been deeply rooted in people's hearts for thousands of years. Pulse diagnosis is a special skill that is not only closely related to Chinese medicine diagnosis and treatment, but also plays an irreplaceable role in the development of Chinese medicine.

[0003] Looking at the current application of pulse diagnosis at home and abroad, there are very few doctors who can truly master and apply this technology. This technology, which has been passed down for two thousand years and is full of profound connotations and historical background, is on the verge of being lost. The reason is that the ancient pulse theory pays more attention to the direct correspondence between pulse characteristics and disease signs, but does not clearly analyze the process of obtaining pulse characteristics. Traditional pulse theory uses a lot of "synaesthesia" rhetoric methods to describe pulse diagnosis, connecting the feelings of different senses, using association to cause sensory transfer, and "writing feelings with feelings". For example, the phrase "like a sick silkworm eating leaves" for astringent pulse is to use visual perception to describe the feeling of the fingers. Traditional pulse often has the phenomenon that a single pulse is composed of multiple factors. This pulse form composed of multiple variables is not a fixed form, but a group of figurative references. For example, "pulsation" is a complex of several conditions such as floating, large, hollow, and weak. Apart from the above reasons, traditional pulse theory only defines and analyzes pulse based on the cognitive conditions at that time, and it is difficult to express the pulse in depth. For example, the floating pulse is "like a floating wood on water", which does not indicate whether it is visual or tactile. If it is visual, the floating pulse is the position of the pulse in the vertical fluctuation of space; if it is tactile, the floating pulse is the force of the pulse floating up, that is, the pressure, felt by the fingers. The string pulse is "like pressing the strings of a guitar", which does not indicate whether the strings are dynamic or static during playing. There is an obvious difference in the finger feeling between the two. Another ambiguity is the understanding of the definition of pulse diagnosis. For example, the delay in "inch number" and "inch delay" does not refer to the heart rate, but to the conduction speed of the pulse wave and the blood flow speed.

[0004] The above reasons ultimately lead to difficulties in the inheritance, learning and development of pulse diagnosis.

[0005] Pulse diagnosis is a specialized skill that requires correct content teaching, repeated practice, and the establishment of a series of complete psychological processes such as feeling, cognition, and thinking related to pulse diagnosis in order to truly master it. The current pulse diagnosis teaching model is still mainly based on theoretical teaching, which only establishes a "semantic memory system" for pulse diagnosis learning rather than a "contextual memory system" that can truly guide operational practice. Theoretical teaching is far from clinical practice, causing learners to linger in the situation of "easy to understand in the mind, but difficult to understand with the fingers" for a long time.

[0006] My pulse diagnosis system "Holistic Mind-Body Differentiation of Pulse" is created on the basis of integrating systemic differentiation of pulse and traditional pulse. Holistic mind-body differentiation follows the basic principles and laws of system theory, and uses the basic principles of traditional Chinese medicine, cognitive psychology, modern informatics and physics to form a new pulse system with unique insights, accommodating multiple disciplines and covering multiple levels. It differentiates the complex pulse system into 25 pairs of single attribute pulse elements, and can describe and measure subjective feelings using indicators similar to modern physics. Systematic syndrome differentiation and pulse science incorporates "system science" into pulse research, believing that pulse is a complex information system, and that pulse information can be differentiated into a variety of physical properties. It uses traditional Chinese medicine theory to analyze pulse elements and the internal mechanisms of their occurrence, the correlation and logical relationship between pulse elements, and the objective "chain of evidence" that characterizes the causes, symptoms, and pathogenesis of the occurrence and development of diseases, as well as Western medicine diseases, providing a reliable basis for syndrome differentiation and treatment. It innovatively introduced a corresponding syndrome differentiation theory system of "one pulse, one syndrome, one treatment" and established a new "symptom differentiation for flat pulse" pulse prescription (medicine, acupuncture, etc.) corresponding treatment system, and various treatment measures are organically unified under the conclusions of pulse diagnosis and analysis.

[0007] Under the guidance of this theoretical system, a new teaching model of "situational cognition" for systematic pulse diagnosis has been established. It emphasizes the development and differentiation of the sensory function of the patient's fingers, consciously strengthens their open "single factor" sensory channels, improves the sensitivity of pulse diagnosis, and ultimately makes all sensory channels sensitive, precise, and accurate, and establishes a "situational memory" system for the feeling of various pulse characteristics in their brains. Compared with the traditional pulse diagnosis teaching model, this new teaching model is systematic, scientific, standardized, practical, and easy to operate. Summary of the invention

[0009] The technical solution of the present invention to solve the technical problem is: a pulse monitor heart-mimicking dual-power circulation system, characterized in that it includes a first diaphragm pump, a second diaphragm pump, a vascular channel controller, a caliber size adjustment controller, a bionic blood vessel, a bionic arm, bionic blood and a pipeline; the bionic blood is stored in a corresponding container; the inlet of the first diaphragm pump is connected to the container through a pipeline, the outlet of the first diaphragm pump is connected to the proximal end of the bionic blood vessel through a pipeline, and blood is pumped into the bionic blood vessel by the first diaphragm pump; the distal end of the bionic blood vessel is connected to the container; the bionic blood vessel is located at the position where the three acupuncture points of Cun, Guan and Chi on the radial artery of the bionic arm are located; the inlet of the second diaphragm pump is connected to the proximal end of the bionic blood vessel through a pipeline, and the outlet of the second diaphragm pump is connected to the container; the restoration simulation of the convergence of the pulse element is realized by the coordinated work of the two diaphragm pumps, the first diaphragm pump simulates the heart to pump blood to the bionic blood vessel at intervals, and in the second half of the first diaphragm blood pumping process, the second diaphragm pump draws blood to present a convergence image of insufficient expansion.

[0010] A pulse pipe controller is provided on the inlet of the second diaphragm pump or on the pipe where the inlet is located.

[0011] The pulse monitor heart-mimicking dual-power circulation system according to claim 1 is characterized in that a caliber adjustment controller is provided on the distal end of the bionic blood vessel or on the pipeline where the distal end is located.

[0012] It also includes a voice system; corresponding voice prompts are set while each convergence and dispersion action is performed.

[0027] The present invention is further described below in conjunction with relevant TCM theories, the accompanying drawings and specific implementation methods.

[0028] This pulse monitor can restore the pulse elements: convergence and dispersion.

[0029] Definition and significance of pulse elements:

[0030] Convergence and dispersion refer to the contraction and relaxation of the radial artery. Convergence refers to the limited expansion of the radial artery pulse and rapid convergence; dispersion refers to the excessive expansion of the radial artery pulse and insufficient convergence.

[0031] The meaning of representation.

[0032] 1) Differentiate between cold and heat: According to traditional Chinese medicine, heat disperses and cold contracts. Therefore, when one is affected by cold, the meridians become tight and the blood vessels do not dilate enough, resulting in a "constricted" state. When one is affected by heat, the meridians relax and the evil heat in the blood is released, the blood vessels dilate too much, resulting in a "dispersed" state.

[0033] 2) Distinguish the deficiency or excess of Qi: Yang Qi has a governing function. If the positive Qi is sufficient and the governing function is strong, the pulse will show a "gathered" pattern. If the Qi is deficient and the governing function is weak, the pulse will show a "scattered" pattern.

[0034] like Figure 2 As shown, the present invention includes a first diaphragm pump 1 and a second diaphragm pump 7, a vascular channel controller 6, a caliber size adjustment controller 5, a bionic blood vessel 3, a bionic arm 4, a voice system, bionic blood and a pipeline 2.

[0035] like Figure 2 As shown, the bionic blood is stored in a corresponding container 8. The inlet of the first diaphragm pump 1 is connected to the container 8 through a pipeline 2, and the first diaphragm pump 1 draws bionic blood from the container 8. The outlet of the first diaphragm pump 1 is connected to the proximal end of the bionic blood vessel 3 through a pipeline 2, and the first diaphragm pump 1 pumps blood into the bionic blood vessel 3. The distal end of the bionic blood vessel 3 is connected to the container 8, and the bionic blood is discharged from the distal end of the bionic blood vessel 3 into the container 8. The bionic blood vessel 3 is located at the radial artery of the bionic arm 4, simulating the pulse of the three acupuncture points of Cun, Guan, and Chi on the radial artery of the arm. The inlet of the second diaphragm pump 7 is connected to the proximal end of the bionic blood vessel 3 through a pipeline 2, and the outlet of the second diaphragm pump 7 is connected to the container 8. Through the action of the second diaphragm pump 7, part of the blood at the proximal end of the bionic blood vessel 3 is sucked away within a certain period of time to appropriately reduce the blood pressure in the bionic blood vessel 3 to simulate the feeling of pulse beating.

[0036] The inlet of the second diaphragm pump 7 or the pipeline 2 where the inlet is located is provided with a vascular channel controller 6, which is used to prevent the bionic blood from flowing back to the second diaphragm pump 7. When the first diaphragm pump 1 pumps blood to the bionic blood vessel 3, the bionic blood easily flows back into the second diaphragm pump 7, causing insufficient blood in the bionic blood vessel 3, seriously affecting the pulse demonstration effect. The pipeline between the second diaphragm pump 7 and the bionic blood vessel 3 is closed by the effect of the vascular channel controller 6, which can prevent the bionic blood from flowing back. When the second diaphragm pump 7 is working, the vascular channel controller 6 is opened so that the bionic blood can flow in an orderly manner.

[0037] The distal end of the bionic blood vessel 3 or the pipeline where the distal end is located is provided with a caliber size adjustment controller 5, which adjusts the bionic blood flow rate and further adjusts the pulse pressure at the bionic blood vessel 3. When the pulse element converges, the caliber size adjustment controller 5 will reduce the pipe mouth to force the pressure of the radial artery (Cun, Guan, and Chi regions) to increase, which is more conducive to the effect of presenting the convergence of the pulse element, otherwise, the pulse element will be scattered.

[0038] The pulse element dispersion is completed by the first diaphragm pump, the bionic blood vessel caliber size regulator, etc. The larger the caliber, the smaller the pressure in the bionic blood vessel 3 radial artery (Cun, Guan, and Chi areas), presenting a soft and weak state.

[0039] When simulating the dispersion of pulse elements, the unit time and speed of expansion and contraction of the radial artery are different, the time and speed of contraction are greater (slower) than the time and speed of expansion, and the simulated blood vessel caliber regulator makes the caliber of the simulated blood vessel larger, making the radial artery of the arm (Cun, Guan, and Chi areas) become dispersed and soft, thereby producing dispersion of pulse elements.

[0040] During each gathering and dispersing movement, a voice prompt is set to provide corresponding pulse information. The voice and the blood vessel wall work together to achieve the effect of experiencing both touch and hearing.

[0041] like Figure 3 , 4 As shown, the two diaphragm pumps each include a housing, a motor, a crank 9, a connecting rod 10, a diaphragm 11, an inlet valve 12 and an outlet valve 13. The motor drives the crank 9 to rotate, and the crank 9 pushes and pulls the diaphragm 11 through the connecting rod 10. When the diaphragm 11 is pushed, the bionic blood in the diaphragm pump cavity is discharged; when the diaphragm pump is pulled, the bionic blood is sucked into the pump body of the diaphragm pump. The motor has the function of controlling the rotation angle and rotation speed, such as a stepper motor or a servo motor. The motor of the first diaphragm pump 1 can be a 180° motor or a 360° motor. The so-called 180° motor means that the motor rotates back and forth between 0° and 180°, and the 360° motor means that the motor can rotate continuously.

[0042] The two diaphragm pumps work together to achieve a restoration simulation of the convergence of the pulse elements. Each working cycle simulates the heart beating once, and the pulse beats once. The first diaphragm pump 1 simulates the heart's intermittent pumping of blood to the bionic blood vessel 3. During the second half of the blood pumping process of the first diaphragm pump 1, the second diaphragm pump 7 draws blood to reduce the pressure in the bionic blood vessel 3, so as to better present the convergence of insufficient expansion, that is, the state of rapid convergence without reaching the predetermined expansion degree. The above actions are closely coordinated to complete the contraction and relaxation of the pulse with convergence. It can be operated according to the set value, such as how many pulse beats are run per unit time, 70 pulse beats in one minute, or 60 pulse beats, etc.

[0043] like Figure 4 As shown, in Figure 4 In the figure, a represents the working sequence diagram of the first diaphragm pump of the 180° motor, b represents the working sequence diagram of the first diaphragm pump of the 360° motor, and c represents the working sequence diagram of the second diaphragm pump. When the pulse elements are restored and simulated, the specific working process of the two diaphragm pumps in a single cycle is as follows:

[0044] S1: At time t0, i.e., the starting point of a single cycle, the crank 9 of the first diaphragm pump 1 is at the 0° position, and the crank 9 of the second diaphragm pump is at the 90° position; wherein 0° refers to the direction in which the crank 9 points to the diaphragm 11, and at 90°, the crank 9 is perpendicular to the direction of the diaphragm 11; from time t0 to t1, the crank 9 of the first diaphragm pump rotates from 0° to 60°, and the first diaphragm pump 1 absorbs the bionic blood in the container 8; the crank 9 of the second diaphragm pump rotates from 90° to 0°, and discharges the bionic blood into the bionic blood container 8; and at the same time, the vascular channel controller 6 is quickly closed;

[0045] S2: from time t1 to t2, the crank 9 of the first diaphragm pump rotates from 60° to 120°, and the first diaphragm pump 1 sucks the bionic blood in the container 8;

[0046] S3: from time t2 to t3, the crank 9 of the first diaphragm pump rotates from 120° to 180°, and the first diaphragm pump 1 sucks the bionic blood in the container 8;

[0047] S4: from time t3 to t4, for a 180° motor, the first diaphragm pump crank 9 rotates from 180° to 80°; for a 360° motor, the first diaphragm pump crank 9 rotates from 180° to 280°, and starts to perform the first blood pumping action to the bionic blood vessel 3;

[0048] S5: From time t4 to t5, for the 180° motor, the first diaphragm pump crank 9 rotates from 80° to 60°; for the 360° motor, the first diaphragm pump crank 9 rotates from 280° to 300°, and the second blood pumping action is performed to the bionic blood vessel 3, and at the same time, the vascular channel controller 6 is opened;

[0049] S6: From time t5 to t6, the crank 9 of the first diaphragm pump rotates to 0° to perform the third blood pumping action to the bionic blood vessel 3, and at the same time, the crank 9 of the second diaphragm pump rotates to 90° to quickly complete the suction action.

[0050] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
