Lumbar traction device driven by pneumatic muscles

Abstract

The invention relates to a lumbar traction device driven by pneumatic muscles. The lumbar traction device comprises an upper limb fixing frame and a waist fixing frame, wherein a rotating shaft is connected to the upper limb fixing frame, and is arranged on the waist fixing frame in an inserting manner; a crotch binding belt is connected to the waist fixing frame; and a plurality of pneumatic muscles are connected to the upper limb fixing frame, and are connected with a shoulder binding belt. According to the lumbar traction device disclosed by the invention, the pneumatic muscles are synchronously inflated and shortened in the direction away from the waist fixing frame, so that the shoulder binding belt and the crotch binding belt can cooperate to perform stretching and traction on a human body; a flexible steel wire is arranged on the rotating shaft in a sleeving manner, and is twined on the rotating shaft spirally; the pneumatic muscles and tension springs are connected to the waistfixing frame; one of the pneumatic muscles and the corresponding tension spring are connected with two ends of the flexible steel wire; the pneumatic muscles are inflated and shortened, so that the rotating shaft is driven by the flexible steel wire to synchronously rotate, the tension springs are synchronously stretched, and the upper limb fixing frame and the waist fixing frame can cooperate toperform rotation and traction on the human body; and through the elastic acting force of the tension springs, after rotation and traction are completed, the upper limb fixing frame is returned.

Description

technical field [0001] The invention relates to the field of lumbar traction devices, in particular to a lumbar traction device driven by pneumatic muscles. Background technique [0002] In recent years, with the increase of the sitting working population, lumbar spondylosis has become a high incidence. According to the survey by the Ministry of Health of the country, the incidence of lumbar spondylosis is second only to colds and has become a common disease that disturbs the public. The human body is affected by its own weight, aging and other factors such as external gravity, pressure, occupational habitual posture and other factors for a long time, which makes the spine supporting the human body and the joints of various parts squeeze or bend, resulting in various Types of lumbar spine diseases occur, bringing pain and discomfort to patients. Medically, for lumbar disc herniation, degeneration disorder, strain, dislocation, lumbar disc herniation or loss of physiological...
