A multifunctional automatic lumbosacral portion concave-traction and arc-shaped-massaging device comprises a front
bed body, a rear
bed body, a convex-concave-type concave structure arranged on the front
bed body and the rear bed body, a concave baseplate,
lower limb supports, three groups of electric push rods between the front bed body and the rear bed body, a chest support, a
lower limb support and three pairs of binding fixing belts of the concave baseplate, a knocking motor, a kneading motor, an
infrared irradiation magneto-therapy device and a
shiatsu device. A traction device can automatically execute up-down, back-forth and crossed motion
modes and has at least four active traction functions and two lumbosacral portion spine rotating functions, and a massaging device can realize massaging functions, in a single, multiple and combined manner, like knocking, kneading,
shiatsu,
infrared irradiating and
magneto-therapy synchronously with the traction device. The multifunctional automatic lumbosacral portion concave-traction and arc-shaped-massaging device has the advantages of comprehensive treatment, high pertinence, obvious
efficacy and low running cost in
waist diseases like
lumbar disc protrusion,
lumbar spine physiological curvature straightening and
lumbar muscle degeneration. A using method includes setting and deploying of a concave-
structure function body, controlling and using of the traction and massaging device and
emergency treatment.
