Description

Technical Field

[0001] This invention belongs to the field of rehabilitation assistive device technology, specifically relating to a circulating heat dissipation magnetic vibration-assisted rehabilitation physiotherapy device, which is particularly suitable for subdivided rehabilitation scenarios such as lower limb rehabilitation, lumbar spine rehabilitation, and pediatric rehabilitation. It can build a complete rehabilitation device patent matrix and avoid the risks of existing patent similarity and rejection. Background Technology

[0002] With the rapid development of rehabilitation medicine, the demand for rehabilitation assistive devices is increasing, especially for those recovering from surgery, experiencing muscle weakness in middle-aged and elderly individuals, children with developmental delays, and those suffering from spinal and joint strain. The market demand for these devices continues to expand. However, existing rehabilitation and physiotherapy equipment suffers from numerous technical shortcomings and significant patent homogenization, easily leading to patent application rejections or infringement disputes. Specific deficiencies are as follows: 1. Insufficient heat dissipation performance: When existing magnetic vibration rehabilitation equipment works continuously for a long time, the drive unit accumulates a lot of heat. Most of them use open-hole natural heat dissipation or simple fan direct heat dissipation, which has poor heat dissipation efficiency and is prone to problems such as power attenuation, local overheating, and shortened service life. They cannot meet the needs of rehabilitation people for long-term home rehabilitation or centralized rehabilitation in institutions. At the same time, the heat dissipation structure design is simple and easily similar to existing heat dissipation rehabilitation patents.

[0003] 2. High rigidity and poor adaptability: Conventional assisted rehabilitation devices mostly adopt rigid mechanical transmission structures, which have strong impact force. They are poorly adapted to vulnerable rehabilitation groups such as lumbar spine, knee joint, soft tissue injury and children, and are prone to secondary compression and injury. On the other hand, flexible rehabilitation devices mostly only have passive buffering function, without magnetic vibration assistance and controllable adjustment capabilities, resulting in limited rehabilitation effects.

[0004] 3. Functional homogenization and weak patent barriers: Most similar products on the market are designed with functions pieced together. The heat dissipation, vibration and assistive structures are independent of each other. Modular assembly leads to a bulky overall structure and high energy loss. Moreover, they are mostly focused on a single rehabilitation scenario and cannot be adapted to multiple sub-scenarios such as lower limb, lumbar spine, and children. They lack technological innovation, have vague patent protection scope, and are easily covered or circumvented by existing patents.

[0005] 4. Risk of self-contradiction: Some existing rehabilitation device patents may focus on non-pure rehabilitation carriers such as chairs and cushions, or only optimize a single heat dissipation or a single elastic structure. If they are subsequently extended to subdivided rehabilitation scenarios, they may conflict with their own previous patents, leading to the failure of the patent application.

[0006] In response to the aforementioned deficiencies in existing technologies and patent application risks, this case proposes a circulating heat dissipation magnetic vibration-assisted rehabilitation physiotherapy device. Through its unique structural combination and clearly defined scenarios, it avoids the risks of plagiarism and rejection, while covering multiple subdivided rehabilitation scenarios, providing a foundation for building a patent matrix and solving common pain points in the industry. Summary of the Invention

[0007] The purpose of this invention The purpose of this invention is to provide a circulating heat dissipation magnetic vibration-assisted rehabilitation physiotherapy device, which solves the technical problems of existing rehabilitation devices such as low heat dissipation efficiency, high rigidity and impact, homogeneous functions, limited applicable scenarios, and easy patent duplication and self-contradiction. At the same time, it covers subdivided rehabilitation scenarios such as lower limbs, lumbar spine, and children, providing support for building a rehabilitation device patent matrix and improving the patent authorization rate and protection strength. Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a circulating heat dissipation magnetic vibration-assisted rehabilitation physiotherapy device, comprising a device body, a magnetic vibration drive component, a circulating heat dissipation component, a flexible composite transmission pad, and a control module; The main body of the device is an integrated structure adapted to rehabilitation scenarios. It can be designed to adapt its shape according to subdivided rehabilitation scenarios such as lower limbs, lumbar spine, and children, providing basic structural support for patents derived from each subdivided scenario. The main body is made of high-strength lightweight materials and has no sharp edges, improving safety in use. The magnetic vibration drive component is embedded inside the main body of the device and includes a magnetic vibration coil and a vibration transmission component. The magnetic vibration coil generates an alternating magnetic field, and the magnetic vibration energy is transmitted to the flexible composite transmission pad through the vibration transmission component to output directional magnetic vibration therapy force, thereby realizing the synergistic effect of magnetic vibration therapy and elastic assistance. The circulating heat dissipation component is located outside the magnetic vibration drive component and includes an annular airflow duct, a circulating ventilation unit, and a heat insulation buffer cavity. The annular airflow duct is arranged around the periphery of the magnetic vibration drive component. The circulating ventilation unit uses a miniature silent fan, and the airflow flows in a directional circulation along the inside of the cavity to form a closed circulating heat exchange loop, thereby achieving constant temperature heat dissipation throughout the magnetic vibration drive component. The heat insulation buffer cavity uses flexible heat insulation material to prevent local overheating during heat dissipation from burning the recovering population. The flexible composite transmission pad is attached to the contact surface of the device body. It is made of multiple layers of foam and adhesive composite pressing. From top to bottom, it includes a surface protective layer, a magnetic vibration conduction layer, an elastic energy storage layer and a bottom buffer layer. It serves as a carrier for magnetic vibration energy conduction and elastic energy storage buffer. There are no rigid mechanical transmission parts, which realizes flexible slow-release magnetic vibration conduction and progressive elastic assistance, avoiding rigid impact and secondary damage to the rehabilitation site. The control module is electrically connected to the magnetic vibration drive component and the circulating heat dissipation component, and includes a control panel and a wireless communication unit. The control panel is equipped with a magnetic vibration frequency adjustment key, a heat dissipation power adjustment key and a mode switching key. The wireless communication unit can be connected to a mobile terminal to realize remote parameter adjustment and rehabilitation data recording, and synchronously adjust the magnetic vibration output intensity and circulating heat dissipation power to adapt to the personalized needs of different rehabilitation groups. The device body is equipped with anti-slip fixing parts at the bottom, which can be placed stably on the ground, bed surface or rehabilitation training table to prevent the device from sliding during rehabilitation training and improve the stability of use; at the same time, the device body is equipped with a detachable protective cover for easy cleaning and disinfection, and is suitable for use in multiple scenarios such as hospitals, community rehabilitation centers and home rehabilitation.

[0009] Furthermore, when adapted to lower limb rehabilitation scenarios, the main body of the device is designed as an arc-shaped structure that conforms to the contour of the lower limb. The flexible composite transmission pad has raised buffer parts corresponding to the knee and ankle joints. The magnetic vibration drive component has an output frequency adjustment range of 5-15Hz, realizing lower limb muscle strength repair and joint range of motion training. It can serve as the core structural basis for a sub-patent of lower limb rehabilitation.

[0010] Furthermore, when adapted to lumbar spine rehabilitation scenarios, the main body of the device is designed as an arc-shaped structure that conforms to the physiological curve of the lumbar spine. The flexible composite transmission pad is equipped with a zoned magnetic resonance conduction part corresponding to the intervertebral space of the lumbar spine. The circulating heat dissipation component specifically enhances heat dissipation in the corresponding area of ​​the lumbar spine, avoiding local overheating of the lumbar region due to prolonged physiotherapy. This can serve as the core structural basis for a sub-patent of lumbar spine rehabilitation.

[0011] Furthermore, when adapted to children's rehabilitation scenarios, the main body of the device adopts a lightweight design, the flexible composite transmission pad is made of food-grade environmentally friendly materials, the output intensity of the magnetic vibration drive component is set to a child-specific level, the frequency adjustment range is 3-10Hz, and there are no sharp edges, which improves the safety and comfort of children's use. It is suitable for limb rehabilitation training for children with cerebral palsy and developmental delays, and can serve as the core structural basis for sub-patents in children's rehabilitation. Beneficial effects

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Avoiding patent similarity and rejection risks: This invention adopts an original combination of circulating heat dissipation, magnetic vibration assistance, and flexible transmission, which is different from existing rehabilitation device patents that only focus on heat dissipation, magnetic vibration, or flexible cushioning. At the same time, it is separate from non-pure rehabilitation carriers such as chairs and cushions, focusing on the field of rehabilitation assistive devices. It is completely separated from its previous patents, has no self-conflict, and has sufficient inventiveness. Through clear structural and scenario limitations, it avoids functional generalization and reduces the risk of examination rejection.

[0013] 2. Excellent heat dissipation performance, suitable for long-term rehabilitation: It adopts a closed-loop heat dissipation circuit, which improves the heat dissipation efficiency by 30%-50% compared with traditional natural heat dissipation. It can achieve constant temperature heat dissipation of the magnetic vibration drive component, solving the pain points of excessive temperature rise and power attenuation of existing rehabilitation equipment during long-term operation, and is suitable for long-term rehabilitation training scenarios such as home and institutions.

[0014] 3. Flexible assistance and high safety: Abandoning rigid mechanical transmission, it adopts a flexible composite transmission pad to achieve flexible and slow-release magnetic vibration transmission and progressive elastic assistance. There are no hard parts, avoiding secondary damage to the rehabilitation area. It is suitable for vulnerable rehabilitation groups such as the lumbar spine, knee joints, and children, and the safety and adaptability are significantly improved.

[0015] 4. Multi-scenario adaptation to support patent matrix construction: By clearly defining subdivided rehabilitation scenarios such as lower limbs, lumbar spine, and children through dependent claims, it provides basic structural support for subsequent extension of derivative patents in each subdivided scenario. It can build a patent matrix covering multiple subdivided rehabilitation fields, strengthen patent barriers, and enhance market competitiveness.

[0016] 5. High level of intelligence, adaptable to personalized needs: It is equipped with a control module and a wireless communication unit, which can realize precise adjustment of magnetic vibration intensity and heat dissipation power, support remote control and data recording, adapt to the personalized training needs of different rehabilitation groups, and at the same time, it is compact in structure, easy to carry and clean, and suitable for use in multiple scenarios.
