Waist automatic adjustment traction device

Abstract

The invention discloses an auto-adjustment type waist traction device. The auto-adjustment type waist traction device comprises a waist fixture, an automatic position adjusting device, a counterweight device, a support face and a traction belt. Unlike a common traction instrument adopting elasticity of a material as traction force, the auto-adjustment type waist traction device uses gravity of the counterweight device as traction force and combines the support face and the automatic position adjusting device to balance the gravity, the traction force and supporting force by adjusting inclination of the support face, and the traction force can be adjusted optionally from zero to the gravity of the counterweight device. The auto-adjustment type waist traction device is better in adjustability and durability than existing similar medical instruments and keeps the traction force unchanged even if the position of a patient's body is changed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a waist traction device with automatic traction control. 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 the jo...

Problems solved by technology

[0003] In order to solve the problem that the existing device cannot adjust the traction force 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, an automatic position adjustment device, a counterweight device, a supporting surface, and a traction belt; The 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, the other end of the connecting belt is connected to one end of the dynamometer, and the other end of the dynamometer is connected to the dynamometer. One end of the traction belt is connected, and its traction force signal is output to the automatic positioning device; 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 automatic positioning device is located at the One side of the support surface can make the support surface rotate along the shaft, and the angle between the support surface and the ground can be fixed at any angle between 0°-90°; the support surface has a 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; There is a fixed structure on one side of the supporting surface with a rotating shaft. The fixed structure includes a "U"-shaped slot and a fastening bolt, and the fastened bolt is also fixed with a suction cup; through the limiting hole
