Abstract
Abstract A stretcher including means which facilitates the transfer of a patient between a bed and the stretcher is disclosed. The stretcher includes actuators for controlling the vertical position of the appliance and also for imparting angular movement to transfer means which can be extended from the appliance. Additionally, the device may be provided with further actuators which are employed to convert the stretcher into a wheel chair by rotating back and foot support platforms relative to a central support member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
288 words
A medical appliance comprising: a base; central frame means; means supporting said central frame means from said base, said central frame means being supported so as to define a substantially horizontal plane; first end frame means pivotally mounted at its first end from a first end of said central frame means, said first end frame means defining an angularly movable extension of said central frame means; second end frame means pivotally mounted at its first end from a second end of said central frame means, said second end frame means defining an angularly movable extension of said central frame means, said second end of said central frame means being disposed oppositely to said first end of said central frame means; means for simultaneously imparting motion in the same rotational direction to said end frame means whereby the angular relationship between said first and second end frame means and said central frame means may be adjusted; first transversely movable slide means mounted on the second end of said first end frame means, said second end of said first end frame means being disposed oppositely to the first end of said first end frame means; second transversely movable slide means mounted on the second end of said second end frame means, said second end of said second end frame means being disposed opposite to the first end of said second end frame means; means for imparting movement to said slide means to cause said slide means to extend and retract with respect to sides of said end frame means included between said end frame means first and second ends; and coupling means affixed to said slide means for attaching opposite ends of a sling to respective of said slide means.
Claim 2
Dependent Claim
288 words
A medical appliance comprising: a base; central frame means; means supporting said central frame means from said base, said central frame means being supported so as to define a substantially horizontal plane; first end frame means pivotally mounted at its first end from a first end of said central frame means, said first end frame means defining an angularly movable extension of said central frame means; second end frame means pivotally mounted at its first end from a second end of said central frame means, said second end frame means defining an angularly movable extension of said central frame means, said second end of said central frame means being disposed oppositely to said first end of said central frame means; means for simultaneously imparting motion in the same rotational direction to said end frame means whereby the angular relationship between said first and second end frame means and said central frame means may be adjusted; first transversely movable slide means mounted on the second end of said first end frame means, said second end of said first end frame means being disposed oppositely to the first end of said first end frame means; second transversely movable slide means mounted on the second end of said second end frame means, said second end of said second end frame means being disposed opposite to the first end of said second end frame means; means for imparting movement to said slide means to cause said slide means to extend and retract with respect to sides of said end frame means included between said end frame means first and second ends; and coupling means affixed to said slide means for attaching opposite ends of a sling to respective of said slide means.
Claim 3
Dependent Claim
47 words
The apparatus of claim 1 wherein said means for imparting movement to each of said slide means comprises: a double acting hydraulic jack mounted within said first end frame means; and flexible means for transmitting the movements of the ram of said jack to said slide means.
Claim 4
Dependent Claim
30 words
The apparatus of claim 2 wherein said means supporting said central frame means comprises: means for vertically adjusting the position of said central frame means with respect to said base.
Claim 5
Dependent Claim
80 words
The apparatus of claim 2 wherein said means for imparting simultaneous motion to said end frame means comprises: third double acting hydraulic jack mounted in said base means; a pair of lever extensions mounted respectively from the first ends of each of said end frame means; and means for mechanically coupling said third hydraulic jack to said lever extensions whereby the angular relationship between said end frame means and said central frame means may be varied simultaneously in opposite directions.
Claim 6
Dependent Claim
30 words
The apparatus of claim 1 wherein said means supporting said central frame means comprises: means for vertically adjusting the position of said central frame means with respect to said base.
Claim 7
Dependent Claim
30 words
The apparatus of claim 4 wherein said means supporting said central frame means comprises: means for vertically adjusting the position of said central frame means with respect to said base.
