Waist manual adjustment traction bed

Abstract

The invention discloses a waist manual adjustment traction bed. The waist manual adjustment traction bed comprises a waist fixing device, a manual position adjustment device, a counter weight device, a support face and a traction belt. According to the waist manual adjustment traction bed, the principle that the common traction appliances utilize the elastic force of a material as the traction force is abandoned, while the gravity of the counter weight device is taken as the traction force, the support face and the manual position adjustment device are combined, and the gravity of the counter weight device is adjusted by adjusting the angle of inclination of the support face, so that the balance among the gravity, the traction force and the support force is achieved, and the traction force can be adjusted randomly within the range between 0 and the gravity of the counter weight device; compared with the existing similar medical devices, the waist manual adjustment traction bed has the better adjustability and durability, and the traction force can not be changed when the body position of a patient changes.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a lumbar traction bed with manually controlled traction force. Background technique [0002] Traction, one of the rehabilitation methods. Use special traction belts and devices to perform stretching exercises on certain parts of the human body. The purpose is to increase the intervertebral space and intervertebral foramen, relieve the compression of the nerve root and the distortion of the vertebral artery, relieve muscle spasm, and reset the protruding intervertebral disc. Commonly used are cervical traction for treating cervical spondylosis, pelvic (lumbar) traction for lumbar disc herniation, and functional traction for improving and enhancing joint function of limbs. Its device can use a non-motorized traction bed with a heavy hammer, a spring balance, or a screw rod for traction, or a motorized traction bed controlled by an electronic device. If it is divided according to ...

Problems solved by technology

[0003] In order to solve the problem that the existing device cannot adjust the traction at will and the cost is high, the present invention makes the following design: the structure of the present invention includes: a waist fixing device, a manual position adjustment device, a counterweight device, a supporting surface, a traction belt, and a traction bed; The waist fixing device includes a waist fixing belt, a connecting belt, and a dynamometer. The waist fixing belt is connected to one end of the connecting belt, and the other end of the connecting belt is connected to one end of the dynamometer. One end is connected to one end of the traction belt; the other end of the traction belt is connected to the counterweight device; there is a rotating shaft on one side of the support surface, and the rotating shaft is movably fixed at the end of the traction bed, and the manual position adjustment The device is located on one side of the support surface, which can make the support surface rotate along the rotating shaft, and can make the angle between the support surface and the ground be fixed at any angle between 0°-90°; the support surface has Slide rail, the counterweight device includes a counterweight box and a counterweight block, the counterweight box is installed in the counterweight box, one side of the counterweight box has rollers, and the rollers slide in the slide rail ; The bedside position of the traction bed also has shoulder fixing straps
