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.
The invention has the advantages that:
1, core of the present invention 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, the one, movable plate and mobile cloth are inserted between patient body and the patient couch top, the 2nd, with movable plate, mobile cloth moves on the carrier for transferring patient together with patient. and 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 sheet on the sick bed to roll even bring between patient body and the mobile cloth. step 2: mobile cloth and movable plate keep relative static, 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, add 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, to prevent that sheet etc. from being carried secretly, even need manually move patient, 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 invention, 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 the present invention 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.
