Abstract

An invalid patient lifting and turning apparatus which includes an open framework for being positioned above a bed, an elevator supported by the open framework and a patient support straps for being positioned on a mattress of the bed underneath the patient and remaining underneath the patient at all times. The straps are removable and replaceable for extending laterally from side-to-side along the length of the patient for supporting the patient'"'"'s head, trunk and legs. Connecting straps are provided for connecting the patient support straps and the elevator thereby permitting the patient support straps to lift the patient above the mattress surface for cleaning and bed-linen changing. A patient turning apparatus is provided for being connected to the elevator for turning the patient from side-to-side in the bed.

Claims

1. An invalid patient lifting and turning apparatus, comprising:

(a) an open framework for being positioned above a bed;

(b) elevator means supported by said open framework, said elevator means including a motor and a winding bar mounted on said framework and extending along the length of the framework for being rotationally driven by said motor;

(c) winding strap means connected to said winding bar and to first and second spacing bars positioned on opposite sides of the framework;

(d) said strap means extending around said winding bar in a clockwise direction and in a counterclockwise direction whereby rotation of said motor in one direction winds said strap means onto said winding bar and rotation in the other direction unwinds said strap means off of said winding bar and thereby lowers or raises said spacing bars;

(e) patient support means for being positioned on a mattress of the bed underneath the patient and remaining underneath the patient at all times, said support means comprising a plurality of spaced-apart, removable and replaceable support strap means secured by opposite ends to said spacing bars and extending laterally from side-to-side along the length of the patient for supporting the patient'"'"'s head, trunk and legs thereby permitting the strap means to lift the patient above the mattress surface for cleaning and bed-linen changing; and

(f) patient turning means for being connected to said elevator means for turning the patient from side-to-side in the bed, said patient turning means including sheet attachment means for being attached to a draw sheet extending under the patient and for being pulled diagonally laterally across the bed from one side towards the opposite side of the bed by said winding strap means.

2. An invalid lifting and turning apparatus according to claim 1, wherein said winding strap means comprises first and second winding straps positioned in spaced-apart relation along the length of said winding bar.

3. An invalid lifting and turning apparatus according to claim 1, wherein said support means comprises first and second sets of straps, one of said first or second sets of straps for being substituted one strap at a time for soiled ones of the other of said first or second sets of straps while the patient is supported above the mattress surface.

4. An invalid lifting and turning apparatus according to claim 1, wherein said sheet attachment means comprises a bar for being passed through a loop in the draw sheet and attached to said winding strap means.

5. An invalid lifting and turning apparatus according to claim 1, wherein each of said support strap means comprise an elongate strap having a soft, thick intermediate portion for being positioned under the patient and opposing end portions having fastening means for permitting the straps to fastened to elevator means used to lift and suspend the patient.

6. An invalid lifting and turning apparatus according to claim 5, wherein said intermediate portion comprises lamb or sheep wool, and said fastening means comprises cooperating male and female hook and loop fastener components.

7. An invalid lifting and turning apparatus according to claim 1, wherein said sheet attachment means comprises a loop on the opposing sides of the draw sheet on opposite sides of the bed for turning the patient from one side to the other from either direction to the other direction.

8. An invalid lifting and turning apparatus according to claim 1, wherein said winding bar extends along the centerline of the apparatus from a footboard end to a headboard end of the bed, said apparatus also including first and second stationary winding bars positioned on opposing sides of said winding bar foe extending along the length of the bed from the footboard end to the headboard end of the bed in laterally spaced-apart relation to said winding bars and in respective vertically spaced-apart relation to said spacing bars, and including roller means carried by said stationary winding bars for supporting said winding strap means.

9. An invalid lifting and turning apparatus according to claim 1, and including means for rolling the apparatus from location to location and into position over a bed.

10. An invalid lifting and turning apparatus according to claim 1, and including attachment means for attaching the framework to the bed.

11. An invalid lifting and turning apparatus according to claim 10, wherein said attachment means comprises support means for supporting the framework on a bed frame of the bed.

12. An invalid lifting and turning apparatus according to claim 1, and including a first brace extending laterally between said spacing bars at one end thereof and including a second brace extending laterally between said spacing bars at the other end thereof, said braces maintaining proper alignment and spacing between said spacing bars.

13. An invalid lifting and turning apparatus according to claim 12, wherein at least one of said braces includes side braces carried by said braces and engaging said spacing bars to maintaining said spacing bars parallel with said winding bar.

14. An invalid lifting and turning apparatus according to claim 1, and including limit switch means carried by said frame and operatively connected to said motor to deactivate said motor when said limit switch is engaged, and detection means cooperating with said limit switch for detecting a predetermined maximum height of the patient above the level of the mattress of the bed and activating the limit switch.
