Description

Technical Field

[0001] This invention relates to the field of intelligent traditional Chinese medicine medical device technology, and more specifically to an intelligent traditional Chinese medicine sealing therapy system based on multi-physics field dynamic coupling, its preparation method, and its control method. Background Technology

[0002] In the field of traditional Chinese medicine physical therapy, the combination of far-infrared thermotherapy and magnetic therapy is widely used to treat conditions such as arthritis and soft tissue injuries due to its gentle nature and minimal side effects. However, existing technologies have many shortcomings that seriously affect treatment efficacy and safety. The main shortcomings of existing technologies are as follows: (1) Lack of thermo-magnetic synergy: Existing equipment cannot achieve effective synergy between far-infrared thermotherapy and magnetic therapy. The two treatment methods work independently and it is difficult to give full play to the advantages of synergistic treatment. (2) High temperature magnetic attenuation: The magnetic properties of traditional magnetic therapy materials are significantly attenuated in high temperature environments, resulting in a significant decrease in the magnetic therapy effect as the usage time and temperature increase; (3) Insufficient precise temperature control: The temperature control accuracy can only reach ±2℃, which cannot meet the precise requirements of different stages of inflammation for treatment temperature, thus affecting the targetedness and effectiveness of treatment; (4) Lack of safety monitoring: There is a lack of effective usage monitoring and lifespan warning mechanisms, and the clinical burn rate exceeds 0.5%, posing a significant safety hazard; (5) Unable to provide personalized treatment: Treatment is carried out using fixed parameters, and the treatment plan cannot be automatically adjusted according to the different stages of inflammation of the patient, making it difficult to adapt to the individual differences and changes in the condition of different patients.

[0003] The core defects in the aforementioned existing technologies are not isolated cases, but rather common problems in the current field of TCM physical therapy equipment. A search revealed that none of the most similar publicly available technologies have provided effective solutions to these defects, and their technical designs still exhibit significant limitations. CN202236864U: The magnetic buckle is only used for mechanical fixation and does not solve the problem of thermo-magnetic field coupling, so it cannot achieve the synergistic effect of thermotherapy and magnetic therapy.

[0004] CN216491113U: The graphene heating plate does not integrate a magnetic therapy module, which limits its maximum operating temperature, results in limited functionality, and has limited therapeutic effects.

[0005] CN110237426A: The magnetic field is a static field, which cannot be dynamically coupled with thermotherapy. It is difficult to adjust the magnetic field strength according to temperature changes during the treatment process, resulting in poor synergistic treatment effect.

[0006] CN117018158A: Single-zone uniform heating, but temperature drift in the edge area is greater than ±3℃, resulting in poor temperature uniformity and easily leading to local overheating or insufficient treatment temperature.

[0007] CN202236865U: Without magnetic therapy pack life monitoring, the burn rate is high and safety is difficult to guarantee.

[0008] In summary, neither the current state of technology within the industry nor the publicly disclosed similar patents have simultaneously overcome the aforementioned key technical challenges. This results in existing equipment failing to meet the actual needs of clinical and home health care in terms of treatment efficacy, safety, and intelligence. Therefore, developing an intelligent TCM poultice therapy technology that can systematically solve these technical problems, achieve dynamic coupling of multiple physical fields, adaptive inflammation staging, and is safe and efficient, has become a pressing issue for those skilled in the art.
