Abstract

The utility model relates to a tracting rotary reduction bed for the vertebra, belonging to the medical appliance of a sick bed. The utility model is composed of a bed seat, a fixing main shaft, a rotary bed surface, a bed frame with slide plates, a bed surface with slide plates, a bracket for a bolt traction belt, the hand operated wheel of a worm reducer, a clutch, two connecting minor axes, etc. The bed body can be tilted by 45 DEG in the maximum and has the function of 60 DEG rotation in the maximum. The horizontal traction mode of the majority of traction beds is changed by the utility model, and consequently, the utility model overcomes the adverse reactions of dizziness, heart rate speeding up, dyspnea, etc., which are caused by the horizontal traction. Power pivot can be changed at any moment when the bed body is rotated, so that traction force directly acts on diseased parts, which not only solves the problem of negative damage, but also solves the problem of insufficient stress on the diseased parts. The utility model is suitable for the bone surgeries and the soft traumatology departments of the medical field and the physical therapy departments and the massage departments of sanatoriums.

Description

Tracting rotary reduction bed for vertebra

This utility model belongs to the sick bed medical apparatus and instruments, be applicable to the Orthopeadic Surgery of medical domain, soft traumatology and sanatorium the department of physiotherapy, Massage Department.

The extension table of domestic each manufacturer production mostly is fixed horizontally tracting at present, and for example original position traction of the described maintenance of China CN2034445 patent patient is a typical example.In addition, the little inapplicable especial patient of pull strength can not be done rotatablely moving of waist, can not do outstanding body traction, can not make outstanding body from the dull and stereotyped traction of body.We find in the clinical practice of more than ten years, because most extension tables is horizontally tracting, so occur dizziness easily, heart rate is accelerated, untoward reaction such as dyspnea.And each tissue of horizontally tracting breast waist muscle ligament spinal column is all stressed, so when normal structure is stressed when having reached the limit and pathological tissues is stressed still not enough.So cause negative damage easily, make therapeutic effect not good enough.

Main cause dizzy and that heart rate is accelerated is: (1) horizontally tracting causes the blood reallocation, increases and cranium is pressed; (2) the chest fixing band is too tight and form momentary vital capacity and reduce, and causes dyspnea.Make rotation bed surface and slide plate bed surface two parts at this problem this utility model lathe bed, can do maximum 45 ° of inclination angles, each one is all stressed for the horizontally tracting vertebra, pull normal structure easily, and pathological tissues does not still have the problem of obvious change, this utility model is set up the spinfunction at maximum 60 ° of angles at lathe bed central longitudinal direction of principal axis, can change the force at any time, make pull strength directly act on diseased region, both solved the problem of negative damage, solved diseased region again and be subjected to hypodynamic problem.

This utility model is according to the whole reduction maneuver design of tradition, and its maneuver that resets is to come work done by machinery.

Accompanying drawing 1 is a pie graph of the present utility model.［ 1 ］ is base among the figure; ［ 2 ］ be fixed main shaft, the rear end car has 500mm long saw shape screw thread; ［ 3 ］ be the rotation bed surface, be installed in the front end of main shaft, but left-right rotation, 60 ° of the maximum anglecs of rotation; ［ 4 ］ be the slide plate bedstead, be fixed on the rear end of main shaft, (203) bearing 8 covers are installed in both sides, contact with the slide plate bed surface, play the slip effect; ［ 5 ］ be the slide plate bed surface, be assemblied on the slide plate bedstead; ［ 6 ］ be two balancing spring pins, be installed in the both sides of rotation bed surface, be rotated by manual clutch; ［ 7 ］ be bolt traction belt support, a rear end that is installed in slide plate bed surface ［ 5 ］, another is installed in the head of rotation bed surface ［ 3 ］; ［ 8 ］ be the worm reduction gear manual pulley, the deceleration footing is fixed on below the slide plate bed surface ［ 5 ］, the worm gear internal diameter is enclosed within on the saw shape thread spindle of main shaft ［ 2 ］ rear end, rotates, and plays draw, its pull strength is 300Kg, ［ 9 ］ being manual clutch, is by two half gear drives that diameter is identical, and lathe bed is tilted, 45 ° of inclination maximums can be done outstanding body traction; ［ 10 ］ be two and connect minor axis, play base and be connected rotary action with lathe bed; ［ 11 ］ be the fixing eyelet of chest, ［ 12 ］ are the fixing eyelet of pelvis; ［ 13 ］ be strain gauge.

This utility model is rational in infrastructure, and cost is low, and is easy and simple to handle, compares good reliability with the pulling equipment of hydraulic means, and motility is good, and adaptability is strong.

Operational approach:

1, lumbar traction:

Patient crouches after (prostrate or lie on the back) on the bed fastens traction belt and rotation fixing band, shaking handle leads to required kilogram number, before the patient was positioned at patient head, both hands pushed away rotary handle, and clutch is pinched out, rotate to required angle to the left or to the right according to the state of an illness and be back to original position then, when traction,, open clutch, bed surface is tilted for preventing patient's dizziness, patient head is raise, and traction finishes and sets back.

2, lumbar vertebra draws from the outstanding body of body:

Patient is prostrate or lie on the back, and fastens chest traction belt and fixing band the head of a bed is elevated to 45, utilizes and draws from heavy sensation of the whole body.

3, cervical traction:

Patient lies on the back in bed surface, fastens cervical vertebra band, can hang to lead, and can do flat leading again.
