Product parametersProduct name: polymer neck inflatable traction deviceProduct material: front support polymer, airbag surface PU, middle TPU, lined with pure cotton clothProduct size: before inflation: 46*14.5cm (neck circumference + height) After inflating: 44*20.5cm (neck circumference + height)Package size: 22*19*17cm 600gUse methodUse time: General traction once 15-30 minutes, 1-2 times a day Cleaning: wipe with a damp towel, preferably not directly water wash;. Maximum traction strength: 2 air pressure (the pump is a pressure limiting valve, to two air pressure will automatically deflate, explosion-proof design, note: do not block the pressure limiting valve hole in the pump when pumping)Product features1. through 20 arc inflatable traction to achieve the role of auxiliary treatment - inflatable air column traction along the up and down direction, strong traction to reduce the pressure of the cervical spine.2. polymer front support, soft and comfortable to wear, support the jaw, fit the head, neck and shoulder physiological curve. 3. Velcro fastening adjustment, adjustable elasticity, non-adjustable height.4. airbags read a small air permeability design, can keep the skin dry and breathable not stuffy.5. large channel air inlet (the first use of gas is not easy too large, need to let the cervical spine gradually adapt), the product inflatable to a certain air pressure, the end of the air pump will automatically deflate, explosion-proof design.Product listEnglish packaging + polymer front bracket + airbag + pump + English manual
