Described front end end of going up movable panel is bending shape slightly downwards, so that movable plate inserts under patient's body smoothly, to avoid the extruding to patient body.

Advantage of the present utility model is:

1, core of the present utility model has been to adopt the combinative structure of last movable panel/last mobile cloth and following movable panel/following mobile cloth, to be transformed into the relative rolling of moving between cloth and patient and the bed surface relative to slip between movable plate and patient and the bed surface, thereby greatly reduced resistance and the frictional force of picking in the patient procedure; Simultaneously, owing to be relative rolling between mobile cloth and patient and the bed surface, thereby movable plate is easy to insert under patient's body, thus in transporting patient procedure, do not need patient body is carried out manual intervention, very easy to use.Be that example is illustrated to receive patient procedure below from sick bed:

The carrier for transferring patient of monolayer movable plate structure in the past, its process that inserts patient generally includes two steps, and the one, with between movable plate and mobile cloth insertion patient body and the patient couch top, the 2nd, movable plate, mobile cloth are moved on the carrier for transferring patient together with patient.Step 1: movable plate slowly outwards protracts along the bed surface of sick bed that patient lies, mobile simultaneously cloth rotates around movable plate, the purpose of rotating is to make not produce between mobile cloth and the patient body and relatively moves, but, owing to be subjected to its structural restriction, the inevitable sick bed relatively of mobile cloth this moment relatively moves, thereby frictional force is very big, consequently not only make the movable plate required resistance that overcomes that protracts very big, movable plate is difficult to insert smoothly under patient's body, and mobile cloth is easy to make the sheet on the sick bed to roll even bring between patient body and the mobile cloth.Step 2: mobile cloth keeps relative static with movable plate, together with the patient's recycled in its entirety on it, thereby mobile cloth is similarly with respect to patient couch top and relatively moves, and adds that load this moment has patient, thereby frictional resistance will be bigger, also be easy to bring into carrier for transferring patient such as sheet on the sick bed.As seen, it in use often needs human intervention, preventing that sheet etc. from being carried secretly, even need manually move patient, and patient is leaned to one side, so that movable plate inserts under patient's body smoothly, so use very inconvenience and resistance big.

And medical use carrier for transferring patient of the present utility model, adopted the combinative structure of last movable panel/last mobile cloth and following movable panel/following mobile cloth, its process that receives patient is: step 1: under drive mechanism, last movable panel and following movable panel slowly stretch out forward, in this process, go up mobile cloth under the batching axle drives around on movable panel rotation and keep static with respect to patient body, mobile cloth moves with respect to following movable panel and keeps relative static with patient couch top down, and go up that also maintenance is relative static between the binding face of mobile cloth and mobile cloth down, thereby in the process that movable plate mechanism integral body is protracted, except exist between mobile cloth and the corresponding movable plate relatively move, there be not any other relatively move, also we can say, do not exist as the sliding friction between mobile cloth and the patient couch top etc., thereby resistance is very little, and the sheet on the sick bed in fact keeps relative static with down mobile cloth, it is hereby ensured that movable plate inserts under patient's body smoothly, and sheet can not driven yet.Step 2: movable plate mechanism reclaims synchronously together with patient is whole, in this process, clutch disconnects, the batching axle stops operating, be static relatively between last mobile cloth, last movable panel, following movable panel and the patient, down mobile cloth is with respect to movable panel down and go up mobile cloth relative motion, but still is relative static between mobile cloth and the patient couch top down, thereby resistance is still smaller and do not have a problem of winding sheet.Thereby this utility model greatly reduced resistance and the frictional force of picking in the patient procedure, and simultaneously, movable plate can insert under patient's body very wellly and not need patient body is carried out human intervention, so very easy to use.Especially under the situation that has installed controller additional, only need just can finish whole process, and do not need other human intervention by key button.

2, moving resistance is little, so consumed power is less, can adopt lower-powered drive motors, to drive disk assemblies such as tooth bar require relatively lowly, help improving the load capacity of car load, help reducing manufacturing cost simultaneously.

3, adopted clutch to drag changement on the structure, simple structure, the lathe bed volume reduces, and weight saving helps reducing the integral production cost.

Patient being received the step that shifts on the car from the sick bed is: 1, to shift car is pushed into by the sick bed, step on braking foot-operated 6 in case spline is moved car moves, regulate lifting support 3 by hand held controller 13, make movable plate mechanism be in proper height, the small machine 41 that starts clutch driving mechanism by hand held controller 13 rotates in the direction of the clock, at this moment, pinion 42 turns clockwise, driving two pinion racks 40 draws close along chute 39 slippages, thereby drive by stayed mast 43; Rocker arm 44; linkage that push rod 45 constitutes; finally cause push rod 45 to leave clutch and move bar 47; clutch move bar 47 promptly under the effect of spring 48 elastic force to vehicle frame 2 inboard translations; and therefore no longer plate-like block 36 is applied outside thrust, the movable end 202 of clutch 20 promptly under the elastic force effect of turriform compression spring 37 stiff end 201 to clutch 20 move and form engagement.Then, start the drive motors 32 of driving mechanism by hand held controller 13, drive motors 32 is successively by power output sprocket 31, roller chain 30, head sprocket 29, pitman shaft 28, middle head sprocket 33 drives drive balls chain 35,16 reaches of 35 drive end connectors of drive balls chain pedestal, the reach of 16 whole movable plates of drive of end connector pedestal mechanism, simultaneously, end connector pedestal 16 also drives clutch gear 18 along long tooth bar 19 rolling reaches by batching axle 15,18 of the clutch gears that rolls drive batching axle 15 by clutch 20 and rotate synchronously, mobile cloth 23 rotations in 15 drives of batching axle, just in time identical but direction is opposite because of the rate travel of last mobile cloth 23 and the patient body contact side with the speed of last movable panel 21 reaches, therefore, go up mobile cloth 23 and in fact keep relative static with patient body.Meanwhile, following movable panel 24 reaches, the down drive of mobile cloth 26 infra movable panels 24 reach down, but since down mobile cloth 26 be fixed on by compress strip device 27 on the panel 11 of vehicle frame 2, so its side with the patient couch top contact is relative static with the bed surface maintenance all the time.And, in this process, go up that also maintenance is relative static between the contact surface of mobile cloth 23 and mobile cloth 26 down.In this way, the last mobile cloth 23 of movable plate mechanism, last movable panel 21, following mobile cloth 26, following movable panel 24 insert between patient bodies and the patient couch top, and patient body is positioned on the mobile cloth 23 fully.So far, can stop drive motors 32, make movable plate mechanism stop reach by hand held controller 13.Then, the small machine 41 that starts clutch driving mechanism by hand held controller 13 is by rotation counterclockwise, make push rod 45 elastic force overhanging and that overcome spring 48 and turriform compression spring 37 make clutch move bar 47 translation laterally, clutch is moved bar 47 and is promoted plate-like block 36 outer moving again, and the movable end 202 that therefore drives clutch 20 leaves the stiff end 201 of clutch 20, and promptly clutch 20 is in non-engagement state.Start drive motors 32 counter-rotatings by hand held controller 13 again, drive whole movable plate mechanism and reclaim backward.At this moment, because clutch 20 is in non-engagement state, so clutch gear 18 does not only drive 15 rotations of batching axle with respect to 15 idle running of batching axle.Therefore, go up mobile cloth 23 and still keep static relatively, also static relatively simultaneously with respect to last movable panel 21 with respect to patient body.The then effect recovery down of infra movable panel 24 of mobile cloth 26 down relatively moves thereby exist between the contact surface of last mobile cloth 23 and following mobile cloth 26, but mobile cloth 36 still keeps relative static with bed surface all the time with the side of patient couch top contact down.Finally, patient is transferred to fully and is shifted on the car.

As for patient is transferred to process on operating-table or the sick bed from shifting car again, except operation sequence, substantially with last identical.
