Product parameters: Power supply method: USB power supply / power bank (power bank is not included in the order) Gear temperature: low gear 45, high gear 60 Features: 1. The upright traction overcomes various disadvantages of the previous hospital traction that must be lying flat, and can be pulled by walking, sitting, or standing; 2. Continuous traction and continuous support (dozens of hours are also possible), which consolidates the traction effect and allows the damaged lumbar spine to get a full rest (the patient obviously feels no pressure on the lumbar spine when using it). Compared with the previous traction, the treatment effect is more obvious , the cycle is shorter; 3. The traction force is large and the air expansion force is large. The 25 air expansion columns are evenly distributed around the waist, and stretch at multiple points at the same time to ensure that the vertebral space is opened, and the effect is good; 4. Double function of lumbar and waist protection: while traction treatment, the continuous support belt reduces the pressure on the lumbar spine (the pressure on the lumbar vertebra is less, and the possibility of lumbar spondylosis is less), and the wide belt body can prevent the lumbar spine from leaning forward. Movements that are unfavorable to the lumbar spine, such as side tilt and flashback, are conducive to the recovery of the normal physiological alignment (curve) of the lumbar spine, and play a role in preventing lumbar spondylosis; 5. Treatment safety: 5V voltage, physical therapy, effective and safe; 6. Hot moxibustion physiotherapy: when damp and cold come, hot moxibustion keeps the waist warm, expels the cold, treats the lumbar spine, and protects health; 7. There are 2 magnets around the waist for medical magnetic therapy.
