Description

Automatic extension table

This utility model relates to a kind of medical traction apparatus, the automatic medical extension table of especially a kind of intermittence.

The extension table of present clinical use generally adopts the mode of gravity traction to draw, promptly cervical region or chest are fixed with bandage, just crotch or shank have been tied up bandage in lower body half, this bandage not because of fixed in bed but link to each other with unsettled weight, the gravity of dependence weight stretches to health.This extension table has tangible deficiency, at first once traction beginning pull strength just remains unchanged always, makes muscle, joint in tension always, is unfavorable for the blood circulation organized, and traction effect is not good.This extension table needs earlier the patient to be fixed then to draw with weight, and is very inconvenient, and auxiliary massage functions.

Tractive, relaxation phase be in conjunction with blood circulation promoting when the purpose of this utility model provided a kind of traction, and impose massage, extension table easy to use when traction.

For achieving the above object, the technical solution of the utility model is as follows: a kind of automatic extension table, it comprises bedstead, bed board and actuating device, bed board is overlying on the bedstead, and be divided into movable bed plate and quiet bed board two parts, two parts are in the same plane, quiet bed board and bedstead are fixed together, quiet bed board respectively has the plurality of fixed bar jack away from the both sides of movable bed plate one end, and both sides respectively have a fixed bar to be inserted in the fixed bar jack, and the movable bed plate is put on the scroll wheel of bedstead, and scroll wheel is bearing on the bedstead, movable bed plate bottom surface is provided with the strip groove that adapts with scroll wheel, scroll wheel places in the groove, and movable bed plate middle part is fixed with a bandage, and the motor in the actuating device is fixed on the bedstead, driven by motor one eccentric disc, the eccentric shaft on the eccentric disc flexibly connects by scalable guide rod and the cant board that is fixed on the movable bed plate bottom surface.

Quiet bed board upper edge centrage has row's massage hole, each massage have in hole one with quiet bed board massage head independently mutually, massage head links to each other with adjustable support bar, adjustable support bar passes the sleeve pipe that flexibly connects with bedstead and links to each other with eccentric shaft on the massage eccentric disc, the massage eccentric disc is bearing on the bedstead of quiet bed board below, and by driven by motor.

Owing to adopt the eccentric reciprocating type tractive form of driven by motor to make muscle, joint be in anxiety, lax alternating state, promoted the tissue blood circulation, the massage of massage head makes the tractive effect more outstanding in addition, ankylosing spondylitis, hyperosteogeny, intervertebral disk hernia, lumbar muscle strain etc. there are good curative effect, and patient's tired painful sensation when not having continuous traction.In addition, the patient can regulate beginning, the end of traction automatically by electric switch, and is very convenient.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is an installation diagram of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is the structural representation of elastic buffer among Fig. 1.

In Fig. 1, extension table comprises traction element and massage section, the traction element main body is a bedstead 1, bedstead 1 is stepped, be fixed with quiet bed board 13 on the high part, the both sides of the part that bedstead 1 is low respectively are fixed with two scroll wheels 3, be covered with movable bed plate 2 on the scroll wheel 3, movable bed plate 2 positions are equal with quiet bed 13 plates, there is a projection at the middle part of quiet bed board and movable bed plate interface, and the movable bed plate have accordingly one the depression (as shown in Figure 2), movable bed plate bottom surface be provided with scroll wheel adapt groove, scroll wheel is embedded in the groove, and the movable bed plate is done horizontal displacement within the specific limits like this.Middle part, movable bed plate bottom surface also is fixed with cant board, be fixed with elastic buffer 15 on the cant board, eccentric shaft on elastic buffer 15 passes through scalable guide rod 4 and draws eccentric disc 14 links to each other, traction eccentric disc 14 is driven by change speed gear box 6 by motor 5, elastic buffer 15 outsides are a sleeve 15.2, plug 15.1 and quiet plug 15.3 are arranged in the sleeve, moving plug 15.1 links to each other with scalable guide rod 4, quiet plug 15.3 positions are fixing by bolt 15.4, between moving plug and the quiet plug is a buffer spring (as shown in Figure 4), by regulating the position of quiet plug, control the purpose that movable bed plate translation stroke is regulated pull strength thereby can reach.Be fixed with a bandage 16 above the movable bed plate 2, be used for fixing patient's crotch or lower limb, bandage 16 degrees of tightness are adjustable (as shown in Figure 2).Quiet bed board 13 respectively has the plurality of fixed bar jack away from the both sides of movable bed plate 2 one ends, and both sides respectively have a fixed bar 12 to be inserted in the fixed bar jack.Also have row's massage hole at quiet bed board position of center line, have in each hole one with quiet bed board massage head 11 independently mutually, massage head 11 links to each other with adjustable support bar 9, adjustable support bar 9 passes the sleeve pipe 10 that flexibly connects with bedstead 1 and links to each other with eccentric shaft on the massage eccentric disc 8, massage eccentric disc 8 is bearing on the quiet bed board 13 below bedsteads 1, and is connected with gearbox gear by chain.

Earlier the patient is fixed on the bed board during use, be bandage 16 immobilized patients crotch or shanks, follow then according to the different fixed bar jack of the different choice of patient's height, build, fixed bar 12 is inserted in the fixed bar jack, open motor 5 then, drive traction eccentric disc 14 and 8 rotations of massage eccentric disc, the traction eccentric disc drives the movable bed plate and moves back and forth, general per minute about 40.The massage eccentric disc drive massage head do about, about compound motion.People's vertebra is massaged,, the initial position of the eccentric shaft on the massage eccentric disc 8 can be designed to differ successively 45 degree, will produce the effect of massage successively like this for strengthening massage effect and comfort.The setting of this initial position can be adopted multiple scheme, but should not be considered as structural variation.In addition, the fixed form on the bed board is to adopt fixed bar, anchor ear or traction casing or other common method all should think to drop within the protection domain of the present utility model.
