Abstract
The invention discloses a kind of legs to automatically adjust traction table, it includes leg restraint, automatic position-adjusting device, counter weight device, supporting surface, leash；The present invention has abandoned the principle that common traction equipment makees tractive force using material forces, the gravity of counter weight device is used to make tractive force and is combined with supporting surface, automatic position-adjusting device by the gravity of counter weight device by adjusting the angle of inclination of supporting surface, reach gravity, tractive force, support force three balance, 0 tractive force can be arbitrarily adjusted between counter weight device gravity, there is better controllability and durability, and patient's change body position will not change tractive force compared to existing similar medical equipment.
Description
Technical field
The present invention relates to area of medical devices more particularly to a kind of leg in traction beds for automatically controlling tractive force.
Background technology
One of traction, method of rehabilitation.With special leash and device, drawing practice is carried out to human body a part.Purpose
It is increase interbody space and intervertebral foramen, releases the compressing of nerve root and the distortion of vertebral artery, alleviate muscle cramp, makes the vertebra of protrusion
Disk resets.Pelvis (lumbar vertebrae) traction and improvement of the common cervical traction for having treatment cervical spondylosis, the protrasion of the lumbar intervertebral disci
With the function traction for promoting extremities joint function.Its device, which can utilize weight, spring scale or screw screw rod, makees the non-of tractive force
Motor traction bed or the motor traction bed using electronic device automatic control, if divided according to joint, traction can be divided into vertebra or four
The traction in limb joint.Clinically, spinal distractor is relatively often used；And in spinal distractor, and with lumbar traction and cervical traction
It is most commonly seen, also there is the traction device for leg knee joint or ankle-joint in addition, and general draft gear can not do and take office
Meaning adjusts tractive force, the only very high electronically controlled traction table of use cost.
Invention content
The present invention makes following design to solve the problems, such as that existing apparatus can not arbitrarily adjust tractive force and cost is higher：
Structure of the present invention includes：Leg restraint, automatic position-adjusting device, counter weight device, supporting surface, leash, traction table；The leg
Portion's fixing device includes leg and fixes band, connect band, dynamometer；The leg is fixed band and is connect with described connect band one end；Institute
The connect band other end is stated to connect with described dynamometer one end；The dynamometer other end is connect with described leash one end；It is described
The leash other end is connect with the counter weight device；There is shaft on one side of the supporting surface, which is fixed on described lead
Draw at the tailstock of bed；The automatic position-adjusting device is located at the supporting surface side, and the supporting surface can be made to be rotated along the shaft,
It and can fix the supporting surface and ground the angle any angle between 0 ° -90 °；The supporting surface has sliding rail；The counterweight
Device includes counterweight box, clump weight；The clump weight is loaded in the counterweight box；The counterweight box has idler wheel on one side；The rolling
Wheel slides in the sliding rail；The bedside position of the traction table also has shoulder fixing belt.
Preferably, the sliding rail has two or three, the idler wheel has two rows or three rows.
Preferably, the automatic position-adjusting device includes PLC controller, stepper motor, worm gear, worm screw, the worm gear and institute
The shaft for stating supporting surface is fixed, and the stepper motor drives the worm screw rotation, and the PLC controller is received from the dynamometry
The traction force signal of meter, and make stepper motor that worm screw forward or reverse be driven to reach default according to the required tractive force preset
Value of thrust.
Preferably, band is fixed as leather in the leg, the connect band, leash, shoulder fixing belt are nylon ribbon.
In conclusion the present invention can easily adjust tractive force, by setting the value of tractive force in PLC controller,
The feedback information of tractive force from dynamometer to PLC controller is provided, then relatively and indicates that stepper motor drives branch by PLC controller
Support face rotates, and stops after reaching preset value, realizes closed-loop control and automation, has apparent advantage compared to existing product.
Description of the drawings
Fig. 1 is the first visual angle schematic diagram of the invention；
Fig. 2 is supporting surface partial schematic diagram of the present invention.
Specific embodiment
