Portable lumbar vertebra tractor

Abstract

A portable lumbar vertebra tractor is composed of the supporting frame whose width conforms withthe width of patient, the locking fixer for fixing the relation between upper and lower parts of said supporting frame, upper waist band linked to said upper part via pull rope, and lower waist band linked to the tracting unit via tracting rope and pulley. Its advantages are simple structure, able to be folded, easy operating by patient itself and high effect.

Description

Technical field [0001] The invention relates to a medical device, in particular to a lumbar traction device. Background technique [0002] At present, apparatuses such as traction beds for traction of the lumbar spine used in hospitals etc. have complex structures, and generally require at least one assistant or physician to operate except that the patient cannot operate by himself. Although the small traction device that can be operated by individuals has also been invented, the effect is not obvious or there is inconvenience in operation. For example, Tian Lijia of the Labor Department of Dashitou Forestry Bureau, Dunhua City, Jilin Province applied for a patent on August 80, 8001. The lumbar traction device (application number: 0180181805, publication / announcement number: 8464850, publication / announcement date: August 18, 8001, authorization announcement date: August 18, 8001) consists of two sets of traction structures, each The traction structure consists of a handle w...

Problems solved by technology

[0002] At present, the structures of traction beds and other equipment used in hospitals for traction of the lumbar spine are complex, and generally the patient needs at least one assistant or physician to operate them, and the patient cannot operate them by himself.

Although the small traction device that can be operated by individuals has also been invented, the effect is not obvious or there is inconvenience in operation. For example, Tian Lijia of the Labor Department of Dashitou Forestry Bureau, Dunhua City, Jilin Province applied for a patent on August 80, 8001. The lumbar traction device (application number: 0180181805, publication / announcement number: 8464850, publication / announcement date: August 18, 8001, authorization announcement date: August 18, 8001) consists of two sets of traction structures, each The traction structure consists of a handle with a bevel gear disc meshing with two straight bevel gears in the gearbox. Each straight bevel gear is coaxially fixed on one side of the corresponding bolt in the gearbox. The nut and the flap Fastened in one piece to the belt

This structure has changed the traditional bed-riding traction method, and is easy to carry and use, but the force of traction is uneven, and the traction effect is not good due to its own gravity.
