Below in conjunction with accompanying drawing this utility model is further described:

Using method of the present utility model and principle are such: patient can face upward usually and lie on the body 1, on the backboard on the bed body 14, on the podical plate 5, be respectively arranged with soft mattress on the lower limb plate 6.

When patient need stand up to the left or to the right, shown in Fig. 1,5,7, be installed in dismountable backplate 7,8,9,10,12,13,15,16 and dividing plate 14,17 on the body 1 and reinforce, entangle frenulum hook 20 on the backplate with strap then, the whole bundle of patient jail.Left side handwheel 165 and shift fork 33 if move in the direction of the clock when standing up to the right, rotate right side handwheel 166 and shift fork 33 if connect clockwise direction left when standing up, drive the belt pulley 32 that is contained on the same axle 31 simultaneously, pass to belt pulley 35 by V belt 34, belt pulley 35 is contained on the axle of tape spool worm screw 38, worm screw 38 connects with worm gear 39 engagements, worm gear 39 is contained in the left end of axle 40, right-hand member is equipped with belt pulley 41, connect by V belt 42 and belt pulley 43, belt pulley 43 is fixed on the headstock 18 and can not rotates, when handwheel 165,166 make a body 1 finish the action that bed body integral body is stood up when 0 ° goes to 80 °.When handwheel 165,166 rotated counterclockwise, a bed body 1 restored gradually to 0 °, patient's recovery that lies low.Belt pulley 43 is subjected to the restriction of stopper 171, and when left and right sides handwheel 165,166 went to 80 °, two handwheels slided, no longer can rotational angle.

When patient needs a lifting back and legs and feet portion respective curved, shown in Fig. 1,6,7,8,9, rotatable both sides handwheel 163,164 and shift fork 52, both sides handwheel function unanimity, direction of operating are opposite, and backboard 4 rises when handwheel 163 clockwise directions rotate, podical plate 5 sinks, lower limb plate 6 is fallen; When handwheel 163 counterclockwise rotates, backboard 4 falls, podical plate 5 and lower limb plate 6 rise, when handwheel 163, during 164 rotations, drive shift fork 52 and axle 63, drive the bevel gear 64 in the transmission case 51 simultaneously, bevel gear 64 connects with bevel gear 65 engagements, change direction, bevel gear 65 is contained on the same axle 66 with stud wheel 68, stud wheel 68 connects with stud wheel 69 engagements, stud wheel 69 is contained on the feed screw nut axle sleeve 72, stud wheel 69 rotates feed screw nut 72 is rotated, and pulling leading screw 53 rotates, the other end of leading screw 53 connects by axle 54 and backboard 4, so but jack-up backboard 4 is 0-80 °, because of backboard 4 connects by axle 57 and podical plate 5, backboard 4 bottoms are welded with support plate 55 simultaneously, and support plate 55 connects by axle 59 and pull bar 60, connect by axle 58 and lower limb plate 6 because of podical plate 5 again, lower limb plate 6 rear portions are welded with support plate 62 again, support plate 62 connects by axle 61 and pull bar 60, so when backboard 4 rises, pulling podical plate 5, can sink 0-18 °, and make lower limb plate 6 sinking 0-80 ° by pull bar 60, backboard 4 simultaneously, podical plate 5, but lower limb plate 6 synchronization liftings form interlock.When backboard 4 rises, when lower limb plate 6 is fallen, podical plate 5 can be in 0-18 ° of scope slides before and after in guide groove, make mobile security steady, there is crossbeam 146 front portion of podical plate 5, there is bolster 25,26 at crossbeam 146 two ends, be with slide block 134,135 on the axle 25,26, slide block 134,135 moves in fixing head 136,137,138,139 formed guide grooves respectively, because of fixing head 136,137,138,139 is fixed on the crossbeam 21, so when backboard 4 interlock pulling podical plates 5, the front portion of above-mentioned member supporting podical plate 5 is slided podical plate 5 front and back.

When utensil is urinated and defecated in the needs handover, shown in Fig. 1,7,10,11,12,13, rotatable handwheel 128, when patient urinates and defecates, but clockwise direction rotates handwheel 128, makes bedpan plate 125 rise and shift to patient posterior, but clockwise direction rotates handwheel 128 after the end of urinating and defecating, bedpan plate 125 drops to bedpan outlet 29, presses reed clamp 169 this moment, can extract bedpan 126 out from lead rule 167,168 and clean.When rotating handwheel 128, drive shift fork 162, screw rod 160, cross nut 159, fork plate 158 and central shaft 118 simultaneously; Central shaft 118 connects arm-tie 104,90, because of pull bar 131 passes through axle 129,130 connect arm-tie 104,110, so central shaft 118 rotates and can spur arm-tie 104,110,90,93, can make axle 89 parallel moving in chute 79, axle 92 is parallel moving in chute 84, axle 103 is parallel moving in chute 102, axle 109 is parallel moving in chute 108, axle 120 is vertical moving in chute 94, axle 122 is vertical moving in chute 95, axle 121 is vertical moving in chute 114, axle 123 is vertical moving in chute 117, again because of axle 80,91,105,111 connect seat 81, connect arm-tie 110 because of central shaft 119 again, 93, connect slide plate 113 and bedpan plate 125 because of axle 157 again, axle 124 connects slide plate 116 and bedpan plate 125, axle 132 connects slide plate 86 and bedpan plate 125, axle 133 connects slide plate 88 and bedpan plate 125, all be fixed on the podical plate 5 because of each slide plate again, so when rotating handwheel 128, each central shaft, sliding axle, arm-tie, slide plate, chute, seat, the bedpan plate links simultaneously, when handwheel 128 clockwise rotates, bedpan plate 125 rises the position of shifting to seat 81, when handwheel 128 rotates counterclockwise, bedpan plate 125 is fallen and is shifted out a body 1, seat 81 restores, thereby has finished the rise of the device of urinating and defecating, fall, the translation function that shifts out.

This sick bed is a steel-wood structure, and the crossbeam of connecting rod, the headstock, tailstock, bed body, vertical beam, annular crossbeam are because of carrying and action, and strength is bigger, so make of steel material, backplate, coaming plate, dividing plate can be made of wooden or plastic material.

When standing up about patient, must be bundled in patient on the body 1, with strap in order to avoid fall out.

It is 0-80 ° that this sick bed stands up angle, patient's sitting posture, face upward to lie and all can carry out, should allow patient finish sitting posture earlier during the sitting posture rollover, and then turn on one's side, must not shake again after leaning to one side and sit the handwheel that crouches, in order to avoid patient can not follow a body bending under the rollover state, prevent that patient from being fasten and not feeling well by strap.

It is 0-80 ° that the primary disease head of a bed back of the body rises angle, and the hip drop angle is 0-18 °, and the bent hade degree of shank is 0-80 °, can need to adjust arbitrarily to select by patient.Hip drop 0-18 °, also can make when urinating and defecating buttocks more press close to seat, make and urinate and defecate accurately.

The transfer mechanism of urinating and defecating can be used steel and wooden and plastic material making, four bar linkages, make lightly easy to operate easily, patient can face upward to lie and urinate and defecate, but sitting posture is urinated and defecated again, not receptor site restriction, and urinate and defecate mechanism and bed sports association are one, will take out bedpan when patient leans to one side to overturn, but patient need not take out when rising and retiring.

The sliding plastic plate packing of coaming plate available light becomes rectangle benzvalene form cradle shape around the bed body, not only safety but also be convenient to clean and attractive in appearance.

The installation shaft of the headstock, tailstock must be highly consistent with the installing hole of bed body head, afterbody, on same horizontal axis.

Backplate, dividing plate are movable, dismantled and assembled, must go up firmly tight during use.

The headstock, tailstock are equipped with the drip stand hole, can install and use at any time, and be very convenient.

This sick bed also can become motor-driven electric-controlled type by this principle design, all available electronic control of the function of standing up, rise and retire, urinate and defecate.
