Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a multifunctional physiotherapy device for internal medicine of traditional Chinese medicine. BACKGROUND

[0002] The multifunctional physiotherapy device for internal medicine of traditional Chinese medicine is a medical device that integrates traditional Chinese medicine theory and modern technology, providing multi-modal treatment for internal medicine diseases. Its core design concept is to achieve precise, non-invasive, and personalized treatment by integrating various physiotherapy methods, while considering the convenience and safety of operation.

[0003] In the current multifunctional physiotherapy device for internal medicine of traditional Chinese medicine, the existing traditional Chinese medicine drug guide device faces three major technical bottlenecks. Firstly, the rigidity of the traditional drug guide head is rigid, and it cannot capture the dynamic vector changes of skin tension caused by breathing and movement. The fixed stiffness fitting structure cannot adapt to different populations, such as the difference in elastic modulus between old and young skin, leading to misalignment and drug dispersion under dynamic conditions. Secondly, the drug liquid control is delayed, and the static flow output mode and electronic sensor response delay cannot match the dynamic fluctuations of skin permeability determined by tension and humidity in real time, resulting in inaccurate flow adjustment and drug liquid waste. Thirdly, the system lacks coordination, and the tension sensing, humidity feedback, and flow execution modules are independent of each other, forming an information island and lacking closed-loop adaptive control capability. These defects cause fluctuations in drug penetration efficiency, uncertainty in treatment effect, and waste of medical resources, severely restricting the upgrade of traditional Chinese medicine physiotherapy to dynamic self-adaptation and precise quantification.

[0004] Therefore, we propose a multifunctional physiotherapy device for internal medicine of traditional Chinese medicine to solve the above problems. SUMMARY

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-2 As shown, this embodiment discloses a multifunctional physiotherapy device for internal medicine in traditional Chinese medicine, comprising four rollers 100, a layered meshing stiffness mechanical switching component 400, and a tension and humidity co-sensing component 500. The layered meshing stiffness mechanical switching component 400 and the tension and humidity co-sensing component 500 are all installed on one side of the outer wall of the four rollers 100, and the tension and humidity co-sensing component 500 is installed at the bottom of the layered meshing stiffness mechanical switching component 400. like Figure 8 as well as Figure 10As shown, the layered meshing stiffness mechanical switching assembly 400 includes an adjustment knob 401, a rotating shaft 402, a curved groove 407, a first driven gear 408, a second driven gear 409, and a third driven gear 410. The curved groove 407 is used to convert the rotational motion into a composite motion of axial lifting and lowering of the rotating frame. The first driven gear 408, the second driven gear 409, and the third driven gear 410 are arranged in layers according to height. like Figures 14-16 As shown, the tension and humidity co-sensing component 500 includes three curved sensing arms 510, three spiral guide rails 511, three levers 517, three magnetic sliders 524, and three auxiliary valve cores 530. The three curved sensing arms 510 all adopt a hyperboloid structure to conform to the dynamic curved surface of the human torso. The three spiral guide rails 511 are used to convert the magnitude and direction of skin tension into linear displacement. The three levers 517 are used to amplify minute skin tension. The three magnetic sliders 524 and the three auxiliary valve cores 530 are used to directly convert changes in skin humidity into flow regulation.

[0021] This embodiment primarily addresses three major collaborative technical bottlenecks faced by existing TCM drug delivery devices in current multifunctional physiotherapy devices for internal medicine. Firstly, the rigidity of mechanical sensing means that traditional drug delivery heads cannot capture the dynamic vector changes in skin tension caused by respiration and movement. Furthermore, the fixed-rigidity fit structure is difficult to adapt to different populations, such as the difference in elastic modulus between the loose skin of the elderly and the tight skin of young people, leading to inaccurate fit and drug dispersion under dynamic conditions. Secondly, the sluggishness of drug solution regulation means that the static flow output mode and the response delay of electronic sensors cannot match the dynamic fluctuations in skin permeability determined by tension and humidity in real time, resulting in inaccurate flow regulation and drug waste. Thirdly, the lack of system collaboration means that the tension sensing, humidity feedback, and flow execution modules are independent, forming information silos and preventing the construction of closed-loop adaptive control capabilities. These defects collectively lead to fluctuations in drug delivery efficiency, uncertain efficacy, and waste of medical resources, severely restricting the upgrading of TCM internal medicine physiotherapy towards dynamic adaptation and precise quantification.

[0022] The embodiment is completed to solve the problems of the prior art. Through the cooperation of the tension and humidity synergistic sensing assembly 500 and the layered engagement stiffness mechanical switching assembly 400, the whole process upgrade of traditional Chinese internal medicine physiotherapy from static adaptation to dynamic self-adaptation, from experience regulation to precise quantization is realized. It is different from the traditional passive drug delivery scheme which relies on fixed stiffness fitting, static flow output and manual intervention. The drug delivery process is more suitable for individual differences, more responsive to dynamic conditions, more guarantees clinical efficacy, and more universal. The tension and humidity synergistic sensing assembly 500 converts the two-dimensional changes of skin tension size and direction into precise linear displacement through the mechanical forced vector sensing structure of the spiral guide rail 511. Combined with the force amplification transmission chain of the lever 517, it completely solves the technical bottleneck that the traditional single-stage transmission has no force amplification and cannot drive flow regulation through small skin tension. At the same time, the pure mechanical humidity sensing module of the capillary 522 and the magnetic slider 524 is physically synergistic with the tension sensing link, realizing the synchronous capture of skin tension and humidity and the flow linkage, avoiding the defects of electronic sensor response delay and poor disinfection tolerance. Finally, the tension and humidity synergistic sensing assembly 500 realizes real-time sensing of dynamic tension, synchronous feedback of skin humidity, and precise execution of liquid flow. It forms a non-delay linkage in time and realizes linear matching in parameters, which together constitutes a pure mechanical closed-loop regulation of perception, decision-making, and execution, and completely breaks through the inherent contradiction between dynamic adaptability, parameter synergy, and regulation accuracy in traditional drug delivery schemes. Secondly, the layered engagement stiffness mechanical switching assembly 400 realizes visual stiffness switching of one-button adaptation and full-population coverage through the nested structure of the curved groove 407, the transmission cylinder 406, and the highly layered first driven gear 408, the second driven gear 409, the third driven gear 410, and the three-layer concentric spring. The axial sliding of the driven gear 403 driven by the rotating shaft 402 realizes visual stiffness switching of one-button adaptation and full-population coverage, accurately covering the full range of requirements from old and loose skin to young and tight skin. Through the one-to-one correspondence between the number of turns and the stiffness gear, an intuitive and reliable operation triggering mechanism is formed, which fundamentally eliminates the force control mismatching technical bottleneck of traditional fixed stiffness or electronic regulation schemes in population adaptability, significantly improving the stability of the fitting and the uniformity of the drug delivery under dynamic conditions.

[0038] In the embodiment of the present application, firstly, the capillary tube 522 is made of high borosilicate glass, and the inner wall of the capillary tube 522 is coated with a hydrophilic coating, which can quickly adsorb the water vapor on the surface of the skin. The design of the inner diameter of 0.2-0.5 mm ensures that the internal glycerol aqueous solution can quickly expand or shrink with the change of humidity. According to the data in “Mass transfer problem in microbubble cavity optical microfluidic sensing”, the orientation groove 523 is integrally formed with the capillary tube 522, the four orientation grooves 523 are symmetrically distributed, which can limit the magnetic slider 524 to slide only in the axial direction, avoiding the failure of magnetic coupling caused by radial deviation. Secondly, the surface of the magnetic slider 524 is wrapped with a medical resin coating to prevent corrosion and drug pollution. The first permanent magnet 525 embedded at the bottom of the magnetic slider 524 and the second permanent magnet 533 at the top of the auxiliary valve core 530 are opposite in polarity, which ensures the stability of magnetic coupling. The first limiting sleeve 526 and the second limiting sleeve 528 are made of medical PE plastic material and are fixed on the inner wall of the capillary tube 522 by buckling, which can limit the maximum sliding stroke of the magnetic slider 524 to avoid component damage caused by excessive displacement. The second reset spring 527 is made of medical stainless steel and is connected between the first limiting sleeve 526, the second limiting sleeve 528 and the magnetic slider 524. It is in a slightly stretched state under normal circumstances, which ensures that the magnetic slider 524 can quickly return to the initial position when the skin humidity decreases, realizing the reversibility of humidity sensing and completely avoiding the defects of response delay and poor sterilization tolerance of electronic humidity sensors.

[0041] In use, the entire working process of the TCM internal medicine multifunctional physiotherapy device revolves around the pure mechanical closed-loop regulation and control of precise stiffness adaptation and double-parameter flow self-adaptation. For common internal medicine symptoms of spleen-stomach deficiency and cold, medical staff can first align the tension and humidity synergistic sensing assembly 500 of the device to the patient's abdomen, the Middle-Waist acupoint, the Guanyuan acupoint, and the surrounding waist and abdomen core physiotherapy area, ensuring that the curved surface sensing arms 510 of the three hyperboloid structures are tightly fitted to the dynamic curved surface of the part, adapting to the natural deformation of the skin caused by abdominal respiratory movement and body position change, providing a stable fitting basis for drug penetration of spleen-stomach related acupoints. Then, according to the patient's abdominal skin condition, select the corresponding stiffness gear through the adjustment knob 401 on the upper layer of the drug guide head, where 1 turn is soft stiffness, 2 turns are medium stiffness, and 3 turns are hard stiffness. The adjustment knob 401 drives the rotating shaft 402 to rotate, and the pulley 405 on the solid rod 404 of its outer surface slides along the stepped curve slot 407 of the transmission cylinder 406, converting the rotary motion into the axial lifting of the rotating shaft 402, so that the main gear 403 precisely engages the layered first driven gear 408, second driven gear 409, and third driven gear 410 of the corresponding height, and drives the fixed sleeve at the top of the different springs to rotate through the micro gear 411, thereby locking the corresponding stiffness of the first spring 413 and the second spring 416 and the third spring 419 in three concentric layers, and transmitting the moderate and adaptive stiffness force to the lower layer of the drug guide head through the sleeve 421, achieving stable fitting of the physiotherapy area and avoiding damage to the delicate skin of the abdomen due to too tight fitting or ineffective drug penetration due to too loose fitting. When the device is fitted to the abdominal physiotherapy area, the curved surface sensing arms 510 of the three hyperboloid structures deform with the change in abdominal skin tension, such as abdominal fluctuation during breathing and skin stretching caused by body position adjustment, driving the spiral guide rail 511 to convert the size and direction of the tension into the linear displacement of the ceramic ball 512, the top rod 514 drives the lever 517 through the connecting rod 518 under the constraint of the guide sleeve, amplifies the small tension, and then drives the main valve core 502 to slide along the shunt pipe 501 through the pressure rod 519 and the metal rod 521, thereby achieving stepless adjustment of the main flow of traditional Chinese medicine liquid for regulating spleen-stomach deficiency and cold. When the abdominal skin tension is larger, the flow is moderately increased, and when the tension is smaller, the flow is gently reduced, ensuring uniform penetration of the medicine liquid to the spleen-stomach related acupoints and meridians.The metal rod 521 outside the telescopic silica gel sealing cover 503 synchronously telescopes, effectively ensuring the sealing property, avoiding the leakage and pollution of the medicine liquid to the clothes. The temperature- Yang and spleen- invigorating Chinese medicine liquid after the adjustment is uniformly output to the core acupoint area of the middle- waisted and Guanyuan through the medicine outlet 505 after the buffering of the temporary storage bin 504, and the symptoms of abdominal distension and aversion to cold caused by the deficiency of the spleen and stomach are improved through the transdermal absorption. At the same time, the three capillary tubes 522 close to the abdominal skin adsorb the skin surface water vapor through the hydrophilic coating, and the internal glycerol aqueous solution expands or shrinks with the change of humidity, which drives the magnetic slider 524 to slide along the guide groove 523. The bottom first permanent magnet 525 and the top second permanent magnet 533 of the auxiliary valve core 530 drive the auxiliary valve core 530 to rise and fall through magnetic coupling, realizing the adaptive supplement of auxiliary flow. When the abdominal skin humidity is high, the medicine liquid flow is appropriately increased to improve the drug permeation efficiency, and when the humidity decreases, the second reset spring 527 and the third reset spring 532 drive the components to return to reduce the waste of medicine liquid. In the whole physiotherapy process, when the abdominal skin tension and humidity dynamically fluctuate with breathing and body position, the tension and humidity cooperative sensing assembly 500 captures signals in real time, and the main and auxiliary flow are controlled through pure mechanical linkage without delay. The layered meshing type stiffness mechanical switching assembly 400 continuously provides a stable fitting stiffness that adapts to the abdominal skin, forming a closed loop effect of stiffness adaptation, acupoint targeting, double parameter sensing, and accurate flow regulation, which improves the deficiency of the spleen and stomach and solves the bottleneck of the traditional device static adaptation and adjustment delay. After the physiotherapy is completed, the first reset spring 509, the second reset spring 527, and the third reset spring 532 drive the main valve core 502, the auxiliary valve core 530, and the magnetic slider 524 to return to position, the medical staff reversely rotates the adjusting knob 401 to unlock the spring, and the device is moved to the storage position through the medical polyurethane roller 100, thereby completing the whole physiotherapy work flow for the deficiency of the spleen and stomach.
