Use original manipulator, when the medical worker removes in the enforcement commentaries on classics,, often can only stand in the position that is difficult for the normal application of force, because surgical patient when the enforcement commentaries on classics is removed, generally all is in narcotism, can not cooperate with on one's own initiative again because the ward space environment is limited.These factors have not only increased manpower and have changeed the difficulty of removing, and change to remove at manpower easily and produce contusion, vibration etc. in the process to the surgical patient unsafe factor.

CN85200637 has proposed a kind of design that patient can be changeed the operating pushing bed of moving sick bed to, this scheme has just partly solved removes (change from manipulator and move on the sick bed) to the commentaries on classics of patient's human body, it can not realize with the patient from sick bed or operating-table change and move on the manipulator.

The purpose of this utility model is: propose a kind ofly can realize fully that mechanization is changeed and remove patient's medical manipulator, it has to change patient's human body from certain holder (sick bed or operating-table) moves on this manipulator, can change patient's human body from this manipulator again and move the function that certain holder (as operating-table or sick bed) gets on to, also have the function that walking is transported.

Its solution is: this device mainly is made up of bedstead, bed surface framework and the lifting sheet of foot wheel, it is characterized in that bed surface framework 4 is movable to holder (as sick bed or operating-table) top, actuating device tightens up or loosens the suspender belt 13 of the lifting sheet 14 that hangs thereon by the rotation of rotating shaft 12.

One of improvement of such scheme is: the travelling gear that the lifting armrest of suspender belt shakes the band using pawl to brake drives rotating shaft and rotates and realize, aperture is arranged in the rotating shaft, can hang suspender belt, and twine suspender belt or loosen suspender belt by rotating, can be that motive power realizes the rotating shaft rotation by motor also.

Two of the improvement of such scheme is: the kind of drive that rotating shaft is rotated adopts worm-drive, helps the self-locking that rotating shaft is rotated.

Three of the improvement of such scheme is: have hinge connection and latch on the horizontal edge of bed surface framework, make put down human body and unclamp latch after, can allow lateral frame upwards overturn folding, also can hold a concurrent post bed surface framework outside frame, and rotating shaft can be shirked when device is withdrawn by rotating shaft in order to withdrawing.

Four of the improvement of such scheme is: the feet that two ends, the bed surface framework outside are provided with two foot wheels, after the bed surface framework shifts out, can play the supplemental support effect, and to improve the stress of bed surface framework, can set up movable track on the sick bed.

Five of the improvement of such scheme is: the frame cabinet base is made height-adjustable with feet with being connected of castor.Utilize the mandrel and the dog screw on the footpost of incidental length on the castor to carry out this adjusting and fixing.

Six of the improvement of such scheme is: bedstead is designed to vertical asymmetrical type.Such as approximate " " type.Make the bedstead outside that bigger mobile space be arranged.Device can be shifted in the middle of the bed surface of sick bed or operation table as much as possible.

Seven of the improvement of such scheme is: cancellation fixed guide, bed surface framework directly be fixed on "

" top of type bedstead.Device lateral moves by the bedstead castor and realizes.

Above-mentioned design can be finished by following examples.

As Fig. 1 be: the bed surface framework can on the embodiment sketch map that turns over.

As Fig. 2 be: band can shirk the embodiment sketch map of rotating shaft.
