Due to the translation of the traction bar, the traction pulley conducts pulsed traction to the traction rope so as to realize pulsed force traction of lumbar vertebrae for the patient.

Description

Lumbar vertebra pulsed traction therapeutic bed

This utility model relates to a kind of traction therapeutic prolapse of lumbar intervertebral disc bed for traction.

What the existing bed for traction that is used for the clinical treatment prolapse of lumbar intervertebral disc was traditional is that colligation is fixed a support and load onto pulley on support on used usually sick bed, and pull rope is fastened mass and led row around pulley is sagging naturally.The extension table of this structural shape relies on weight to carry out tractive, and pulling force can't change continuously and is difficult to meet the treatment requirement.Thereby therapeutic effect is undesirable.Moreover, big, the adjustment angle of pull trouble of medical worker's labor intensity during treatment.A kind of multi-functional automatic bed for traction has appearred recently, though treatment greatly reduces medical workers when using, but the instantaneous setting value that reaches of pull strength when its disadvantage is traction therapeutic, rather than meet the requirements of value of thrust gradually, thereby the other soft tissue tear of vertebra easily takes place.Cause symptoms such as edema, so patient often has uncomfortable sensation or pain in treatment clinical course.

The purpose of this utility model provides a kind of traction force can adjust variation continuously, carries out the lumbar vertebra pulsed traction therapeutic bed of pulsed traction during treatment.

Lumbar vertebra pulsed traction therapeutic bed is made of therapeutic bed and traction machine, be fixedly connected with the towing bracket that hauling block and leading block are housed, the bull wheel that has the reverse stop mechanism of ratchet one ratchet, press rope wheel, stretching wheel on the therapeutic bed bedstead, pull rope is wound on the bull wheel, the dynamometry table is housed on the pull rope, and the pull rope free end is the intrinsic hook device that connects with lumbar vertebra tractive kicking strap.Traction machine by support, be fixed on motor on the support, with the reduction gearing mechanism that motor connects, with the commutation drive mechanism of reduction gearing mechanism output coupled, be loaded on the stayed pole of commutation drive mechanism outfan, the tractive pulley that is loaded on the tractive rod end constitutes.The pull rope free end stretches into the treatment bed surface by tractive pulley, stretching wheel press rope wheel, directive wheel, hauling block, by tractive pulley tractive pull rope the lumbar disease patient is carried out traction therapeutic.

In order to improve the structural integrity of bed for traction, the traction machine support supports, is fixed on the therapeutic bed bedstead, between towing bracket and hauling block adjustable apparatus is arranged.Application of force angle by adjusting device scalable, change hauling block high and low position and then adjusting, change traction force.The commutation drive mechanism of lumbar vertebra pulsed traction therapeutic bed is by the eccentric that is loaded on the reduction gearing mechanism outfan and be loaded on that the adjustable cantilevered axle of its degree of eccentricity constitutes on the wheel face, and the stayed pole that rod end is equipped with the tractive pulley is loaded on the eccentric shaft.

The lumbar vertebra pulsed traction therapeutic bed that this utility model provides moves back and forth collapsing tight degree and can regulating the change pulling force continuously of stroke and pull rope by regulate changing stayed pole, thereby makes the pull strength that acts on the patient body reach the requirement that treatment is set.Regulate, change the application of force angle that traction wheel high and low position scalable changes the angle of pull rope and then changes pull strength.With the requirement of satisfied treatment, thereby the traction therapeutic effect of prolapse of lumbar intervertebral disc is greatly enhanced.Moreover therapeutic bed is simple in structure, compact conformation, and cost is low, and is easy to utilize.

Accompanying drawing is an embodiment of the present utility model, further specifies this utility model below in conjunction with embodiment.

Fig. 1 is a lumbar vertebra pulsed traction therapeutic bed structural representation.

Fig. 2 is the A-A cutaway view of Fig. 1.

As shown in the figure, lumbar vertebra pulsed traction therapeutic bed is made of therapeutic bed and traction machine.Be fixedly connected with band on the therapeutic bed bedstead (11) and regulate the towing bracket (3) of installing hole (1), hauling block (2) wheel shaft is loaded in the towing bracket installing hole, by the adjusting of wheel shaft installation site, changes scalable and changes traction application of force angle.The bull wheel (21) that leading block (19) the therapeutic bed bedstead other end is fixed with the band reverse stop mechanism of ratchet one ratchet (9) is equipped with in the towing bracket bottom, and pull rope (4) is wound on the bull wheel.Pull rope is pressed rope, and stretching wheel (15) is loaded in the support of bedstead underbeam by wheel shaft.Traction machine is by motor (18), the eccentric (16) that eccentric cantilevered axle is arranged on the decelerator (17) that connects by pulley transmission mechanism (20) and motor output shaft, the wheel face that is loaded on the reducer output shaft end, the tractive pulley (8) that is loaded on the stayed pole (7) on the eccentric cantilevered axle and is loaded on the stayed pole constitutes, and motor, decelerator support, are fixed in the support of bedstead underbeam by support (22).Stayed pole has guiding, support bar (12).Be fixedly connected with the support (14) of tape guide cover (13) on the bedstead, support bar cooperates with the fairlead sliding friction, supports stayed pole and stayed pole is come and gone translation and lead.The contiguous free end of pull rope is equipped with dynamometry table (5), end is intrinsic hook (6), the pull rope free end stretches into the treatment bed surface by tractive pulley, pressure rope, stretching wheel, directive wheel, hauling block, colludes to hang to be connected with the kicking strap that is fixed on patient's lumbar vertebra vertebra between patient's waist is carried out the tractive treatment.

When utilizing therapeutic bed that prolapse of lumbar intervertebral disc is carried out traction therapeutic, regulate the tight degree that collapses that changes pull rope, and then the pull strength that treatment is applied is finely tuned by bull wheel.Change the position-adjustable of eccentric upper suspending wall axle, change the translation stroke of stayed pole, and then can significantly change the pull strength that acts on patient's lumbar vertebra, treat the application of force angle of pull strength to reach the requirement of traction therapeutic by the lifting scalable change of hauling block axle.(10) are electric power switch among the figure.
