Description

Patient trolley with bed being able to elevate fall and horizontal shift

This utility model relates to a kind of patient's transfer car(buggy) of medical patient's transfer car(buggy), particularly bed surface liftable and translation.

Mostly known patient's transfer car(buggy) is that bed surface can not lifting and translation, and the patient will be carried on, carry off, and medical personnel's operation labor intensity is big, and the patient is also painful simultaneously.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, medical patient's transfer car(buggy) of steady lifting of the bed surface that labor intensity is low and translation.

This utility model is achieved in that sees that Fig. 1 is to shown in Figure 7, castor 7 is housed below the chassis 8, fuel tank 10 is housed on the chassis, lifting piston cylinder 28 is housed in the fuel tank, the oil pump of forming by part 21 and 22, check valve 23 and 24, connect oil pipe line, gate gurgle valve 25(check valve), be contained on the fuel tank sidewall in the case of axle and on the part arm 20 be housed, case is equipped with pedal 9 outside the branch, lifting piston 4 connects with framework 30, framework connects with the tooth rest 6 that travel mechanism and draining handle 11 are housed, the rolling and the guiding mechanism 5 that support bed surface also are housed on the framework, handrail 1, it above the rolling guiding mechanism bed surface assembly 2, it above the bed board 14 cushion 13, the cushion two ends connect with framework respectively, cushion is along there being the pad of reinforcement, to prolong the service life of pad on the edge length direction of bed.Be provided with the spacing and reversing device of bed surface lifting.Rotate handwheel 12, gear will drive the bearing groove 15 with the fastening band tooth bar of bed board, when bed board moves, will produce cushion along identical the moving of bed board moving direction, and the speed of cushion be greater than the speed of bed board, because the cushion two ends are fixed on the framework.The bed surface hydraulicefficiency elevation structure mainly comprises: fuel tank 10, draining handle 11, gate gurgle valve 25(check valve) and tie, be installed in the case of the rotating shaft on the fuel tank sidewall and arm 20 be housed and case is equipped with pedal 9, oil pump piston 21, pump cylinder 22, check valve 23 and 24, spacer pin 27, lifting piston 4, hoist cylinder 28, sealing member and securing member etc. outside the branch inner the branch.The bed surface horizontal mobile mechanism mainly comprises: axle 40 and 42, gear 41,43,45, handwheel 12, in bearing block 44, the power transmission shaft 3 of bearing, the bearing groove 15 that is fixed on the band tooth bar on the bed board, tooth rest 6, key and securing member etc. are housed.The rolling guiding mechanism that supports bed surface mainly comprises: roller 31, axle 32, support 33, gathering sill 34, guide plate 35, bearing groove 36, bearing 37, support 38, securing member etc.The bearing groove 15 of bearing in the travel mechanism and band tooth bar also has the guide-localization effect.

Advantage of the present utility model has been to realize the lifting and the translation of the quick and stable of bed surface, and is simple in structure, connection and reasonable arrangement, and processing ease, easy to maintenance.All can operate at the bed two ends as symmetric design, the foot-operated bed surface of can realizing rises, handle 11 may command gate gurgle valves realize that bed surface descends, handwheel 12 can be finished bed surface and move horizontally, the speed of cushion is higher than the bed board translational speed, connect or send down the patient fast to finish, thereby solved the problem of no longer choosing the patient being carried on, carrying off, alleviated medical personnel's labor intensity and patient's misery.

Accompanying drawing 1 to Fig. 7 is that the sketch map of embodiment of the present utility model: Fig. 1 is that front view, Fig. 2 of transfer car(buggy) is that vertical view, Fig. 3 are that side diagrammatic sketch, Fig. 4 are that bed surface assembly sketch map, Fig. 5 are that bed surface hydraulicefficiency elevation structure sketch map, Fig. 6 are that rolling and guiding mechanism sketch map, the Fig. 7 that supports bed surface is bed surface horizontal mobile mechanism sketch map.Present embodiment adopts a side to handle arrangement.On the chassis 8 that links with four castors 7 fuel tank 10 is housed, the 26th, working solution, here use oil, rotating shaft is contained on the fuel tank sidewall, on its end outside case pedal 9 is housed, on the end in the case arm 20 is housed, the pump of being made up of oil pump piston 21 and pump cylinder 22 is contained in the case, have on the pump cylinder into and oil outlet, check valve 23 and 24 are housed on the oil pipe line, the lifting piston cylinder is also in fuel tank, have fuel feed hole on the cylinder and the drain tap of gate gurgle valve 25 be housed, the draining handle 11 of control gate gurgle valve be contained in framework 30 fastening tooth rests 6 on, spacer pin 27 is arranged on the lifting piston cylinder, with the restriction lifting piston 4 stroke and prevent its rotation, piston 4 connects with framework 30 by connector 29, and a handrail 1 is arranged on the framework, it and draining handle 11, handwheel 12 is in the same side.Each fastening tooth rest 6 of framework two ends, axle 40 and 42 is arranged on it, in the bearing block 44 of bearing and cover 39, gear 41,43 and 45 are housed, an end that is supported on the little axle on bearing block 44 inner bearings connects with power transmission shaft 3, gear 43 is housed on the other end and handwheel 12(is one-sided has), the bearing groove 15 that gear 45 can drive the band tooth bar that is fixed on the bed board 14 moves, support 38 connects with framework, and a plurality of bearings 37 are housed on it, and groove 15 is being with bed board can realize briskly moving stably like this.Rolling and guiding mechanism that one support bed surface is arranged between bed board and framework, it mainly comprises roller 31, axle 32, is fixed on support 33, guide plate 35 on the framework, the bearing groove 36 that is fixed on the bed board connects with gathering sill 34, be contained in the fastening support 38 of framework on a plurality of bearings 37, alignment pin and securing member etc.Supporting above the rolling guiding mechanism is exactly bed surface assembly movably, and it comprises that mainly two ends are fixed on cushion 13, bed board 14, cylinder 16, bearing 17, axle 18, fixed mount 19, connection and the securing member etc. on the framework.Present embodiment also is provided with adnexaes such as transfusion bottle stand, but makes every effort to simply reduce cost.When pedal 9 is ridden, oil pump will be worked, oil is injected into bed surface is risen, control draining handle 11 realizes that gate gurgle valve 25 drainings descend bed surface, rotate handwheel 12, realized that by drive mechanism bed surface has the fast and stable translation of guiding, the patient has been connected or send down and no longer chooses and carry, alleviated medical personnel's labor intensity and patient's misery to finish.
