The JYZ-IB is a multifunctional traction bed for the cervical and lumbar regions (commonly known as a traction bed), utilizing a linear push motor as the power source, an electric mechanical system for the sliding surface of the bed, a point switch to achieve automatic reciprocating traction, support release, and continuous traction functions. The traction bed is easy to operate, safe, and reliable, allowing patients to master the size and force of traction, as well as control the frequency of the traction bed's surface movement back and forth, traction time, and duration of intervals.
