Abstract
A portable, reusable appendage supporting device is provided for elevating the leg of bed-ridden patients for evaluation and treatment to their lower extremities. The appendage lifting device provide a base unit providing a telescopic pole connecting a support element for the patient's appendage. The telescopic pole enables selective elevational adjustment of the supporting element. The present invention also includes a pivot connection and locking mechanism interconnecting the support element and the telescopic pole, so that the orientation of the supporting element can be further rotationally adjusted and secured during use.
Claims13
A device, comprising:
- a base unit;
- a telescopic post extending from the base unit;
- a pivot connection attached to a distal end of the telescopic post;
- and
- a support element pivotably connected to the pivot connection so that the support element is rotatable among a plurality of orientations about a longitudinal axis extending from said distal end.
A device, comprising:
- a base unit comprising a plurality of supporting members extending from a base plate;
- an elastic stopper attached to the distal end of each supporting member;
- a stationary component extending from said base plate;
- an adjustable component positionable between a plurality of elevations along the stationary component relative to the base plate;
- rod extending along a longitudinal axis from a distal end of the adjustable component;
- a bearing block adapted to rotate about the rod among a plurality of orientations relative to the base plate;
- a locking mechanism configured to move between an unlocked condition, allowing the bearing block to selectively rotate, and a locked condition securing the bearing block at one of the plurality of orientations;
- and
- a support element pivotably connected to the pivot connection so that the support element is rotatable among a plurality of orientations about a longitudinal axis extending from said distal end.
