Features: 1. The design is based on the average person's waist length of about 13cm. The waist width is increased to about 20cm when inflated, it can be strongly pulled and protect the waist more widely. 2. A variety of air traction shapes are evenly arranged behind the belt. When the air is pressurized, multiple air columns simultaneously force the stretching of the lumbar vertebrae, more traction, more power. 3. According to the ergonomic principle, the waist of the human body is C-shaped, the belt design is anti-C-shaped, forming an O-shape with the waist, which can strongly support the waist. 4. Fine processing with tightly closed materials, durable to use and lighter in weight. 5. Through the principle of mechanical force and reaction force, the traction force is applied to the lumbar vertebrae, and the intervertebral space is widened to achieve: A. Reduce the pressure of the intervertebral disc, promote the disc return, relieve the stimulation and compression of nerve roots and other tissues. B. Eliminate inflammation, promote blood circulation. C. Relieve tendon and improve local blood circulation. Specification: Product material: PU Belt size inflated deployment: about 115*19.5cm/ 45.28*7.68inch Belt size before restart: about 115*13cm/ 45.28*5.12inch Extension pad size: about 25*11cm/ 9.84*4.33inch Package List: 1*Belt 1*Inflatable Rod 1*Extended Belt Instructions: 1. Wear the pneumatic traction belt directly on the skin surface or underwear surface. 2. Wear on the top of the humerus and below the soft rib arch, clasp the . 3. The air pump clip is aligned with the nozzle connection, and the air pump is pressed by the pedal or the hand to inflate the belt. 4. Inflating the belt until the air column is fully deployed, do not over reach. 5. Wear 30-60 minutes, according to the actual situation can be extended. 6. Relieve the pneumatic traction belt during sleep. 7. When unpacking, unscrew the inflation valve or press the valve ejector to deflate firstly, then untie the traction belt. 8. It is recommended to remove the belt or waist accessories before use, it will feel better. 9. 30 minutes before going to bed to use it, the effect is better.
