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.

Example Embodiment

[0010] Example one
[0011] Such as figure 1 , figure 2 The structure of the present invention shown includes: the structure includes: a waist fixing device, a manual position adjustment device, a counterweight device 6, a supporting surface 7, a traction belt 4, a traction bed 9; the waist fixing device includes a waist fixing belt 1, a connecting belt 2 The dynamometer 3, the waist fixing strap 1 is connected to one end of the connecting strap 2, the other end of the connecting strap 2 is connected to one end of the dynamometer 3, and the other end of the dynamometer 3 is connected to the traction One end of the belt 4 is connected; the other end of the traction belt 4 is connected to the counterweight device 6; one side of the supporting surface 7 has a rotating shaft, which is movably fixed at the foot of the traction bed 9, and the manual position adjustment The device is located on the side of the supporting surface 7, which can make the supporting surface 7 rotate along the axis of rotation, and can fix the angle between the supporting surface 7 and the ground at any angle between 0° and 90°; The supporting surface 7 has a sliding rail 11, and the counterweight device 6 includes a counterweight box and a counterweight block. The counterweight block is installed in the counterweight box. One side of the counterweight box has rollers. The sliding rail slides; the head of the traction bed 9 also has a shoulder fixing belt 14.
[0012] More specifically, there are two slide rails 11 and two rows of rollers.
[0013] More specifically, the manual adjustment device includes a hand wheel 10, a worm wheel 5, and a worm 13, and the worm wheel 13 is fixed to the rotating shaft of the supporting surface 7.
[0014] More specifically, the waist fixing belt 1 is made of leather, and the connecting belt 2, the traction belt 4, and the shoulder fixing belt 14 are nylon webbing.
