Description

Technical Field

[0001] This utility model belongs to the field of lumbar support belt technology, and in particular relates to an intelligent physiotherapy lumbar support belt. Background Technology

[0002] With the fast pace of life, lumbar muscle strain and lumbar disc herniation are becoming increasingly prominent among office workers who sit for long periods, manual laborers, and the elderly, leading to a growing demand for lumbar health and therapeutic treatments. Traditional physiotherapy methods, such as physical therapy and massage, often require specialized equipment and professional assistance, making them inconvenient to use and demanding in terms of treatment environment. Therefore, therapeutic lumbar support belts, with their convenient wearing method and efficient therapeutic functions, have become an ideal choice for solving this problem. However, traditional lumbar support belts on the market typically only offer one function—heating or massage—providing only a limited degree of relief for lumbar discomfort, with insufficient therapeutic effect. Furthermore, they lack the ability to provide personalized treatment plans based on the user's medical history and lumbar environmental parameters, resulting in a low level of intelligence and limiting their widespread application in daily life. Utility Model Content

[0003] To address the shortcomings and deficiencies of existing technologies, a smart physiotherapy lumbar support belt is provided, which can solve the problem that existing lumbar support belts have limited functionality and low level of intelligence, preventing their widespread application in users' daily lives.

[0004] This invention provides an intelligent physiotherapy lumbar support belt, comprising an inner lining layer, a protective layer, a functional layer, a circuit layer, and an outermost layer. The inner lining layer has Velcro fasteners, and the outermost layer has Velcro hooks. The Velcro fasteners and hooks work together to secure the belt to the waist and abdomen. The functional layer is divided into an anterior abdominal region, a right lumbar region, a posterior lumbar region, and a left lumbar region, corresponding to different areas of the waist and abdomen. Each of the anterior abdominal region, right lumbar region, posterior lumbar region, and left lumbar region is equipped with a status sensing module and a physiotherapy module to monitor body temperature. The system senses pressure and electromyography (EMG) and takes corresponding physiotherapy measures. The outermost layer is equipped with a display module and a button control module. The circuit layer contains a central control module, a voice control module, a storage module, and a power supply. The power supply is connected to the central control module, voice control module, button control module, storage module, display module, status sensing module, and physiotherapy module to provide continuous power. The central control module is connected to the voice control module, button control module, storage module, display module, status sensing module, and physiotherapy module to transmit signals and control the movements.

[0005] The beneficial effects of this utility model are:

[0006] Compared with existing technologies, the intelligent physiotherapy lumbar support belt provided by this utility model integrates multiple functional modules through a multi-layered structure. This allows it to provide different levels of heating, vibration, and massage based on the user's uploaded medical history information and the pain status of different areas of the lower back. It can adjust key parameters such as heating temperature, vibration intensity, massage strength, and physiotherapy duration to achieve multifunctional, customized, and precise physiotherapy solutions. At the same time, it also adds a voice control function, allowing users to easily input physiotherapy strategies and upload medical history information, greatly improving ease of use and user experience.

[0007] In summary, this intelligent physiotherapy lumbar support belt enables the physiotherapy process to be dynamically adjusted according to the body's condition, providing personalized and precise physiotherapy solutions that are convenient, quick, scientific, effective, and highly intelligent, greatly enriching the physiotherapy experience and significantly improving the physiotherapy effect.

A state sensing module 36 is located on one side of the massage unit 38, and a vibration unit 39 is located on the other side for vibration therapy of the waist and abdomen. The state sensing module 36 detects muscle activity using an electromyography (EMG) sensor and adjusts the physiotherapy intensity based on muscle tension or fatigue. Simultaneously, a temperature sensor monitors the temperature of the waist in real time to ensure the heating effect reaches the user-set value. Additionally, a pressure sensor monitors the pressure distribution in the waist, analyzes the pain or tension levels in different areas, and adjusts the vibration intensity of the massage unit 38 in the physiotherapy module based on the pressure data.

Several massage heads 381 are provided on the surface of the massage disc 382 near the protective layer 2 to improve the effect of massage therapy. A protective component 384 is movably sleeved in the middle of the rotating shaft 383.
