Embodiment Construction

[0012] Such as figure 1 As shown, place the mechanism on the stool, adjust the thread of the armpit bracket 1 to make the total length to a suitable length, so as to ensure that there is a suitable suspension distance between the person's buttocks and the stool surface, and then use the auxiliary fastening nut 2 to fix the armpit bracket. Adjust the length of the upper waist nut 4 to make the upper waist belt 15 reach the appropriate position of the human body, then the patient is placed on the bracket, and the upper waist belt 15 is fastened, so that the total weight of the human body is distributed to the armpit bracket 1 and the upper body. The waist belt 14 avoids too much concentration on the armpit bracket 1, which increases comfort. Then fasten the lower waist belt 15, pull the handle on the traction mechanism to reduce the distance between the lower waist belt 15 and the stool surface, thereby producing a certain additional pulling force. achieve therapeutic effect. ...

Abstract

The invention relates to a sit-down lumbar tractor, which takes two support sleeves as the main body and comprises an elevator armpit supporting bracket, an upper nut of waistband, a manual loading mechanism, a lower sleeve of waistband, a base and a waistband. The invention takes the resultant force of the body deadweight and the manual load as the traction force and all the mechanical displacements along the traction force direction are achieved by screw thread transmission. The sit-down lumbar tractor has the advantages of compact and simple structure, easy and convenient force application, so is suitable for the patient lumbar disease to use during trip and at home.

Description

technical field [0001] The invention relates to a medical device for treating lumbar spondylosis, in particular to a sitting lumbar traction device. Background technique [0002] At present, the devices used for traction treatment of lumbar spondylosis include traction beds and small tractors. The differences in the power source and transmission mode of the traction force make the structure of the lumbar traction devices different. The power source of the tractor can be manual, electric, pneumatic and hydraulic. Among them, the electric, pneumatic and hydraulic methods are mainly used for the traction bed, and the small tractor mainly adopts the manual method. The transmission method of the traction includes the transmission of the traction through the wire rope of the wheel train, the transmission of the traction by the gear mechanism, and the transmission of the traction by the cylinder. These methods have the defects of uncompact structure, complex mechanism, sudden chan...
