Abstract
A cyclic therapeutic hand exerciser based on inflation and deflation of structural members, which alternately imparts a straightening and a bending motion to the fingers wherein as air pressure inflates a splint-like upper member the fingers are straightened and upon deflation of the splint-like member and inflation of a wrist pouch a flap is tightened pulling the fingertips down and curling the fingers in toward the palm.
Claims11
A therapeutic hand exerciser comprising:
- upper inflatable pouch means which when attached to the fingertips and arm of a disabled individual and inflated has sufficient rigidity to straighten the fingers of the individual, and when deflated is sufficiently pliable to permit the fingers to bend;
- first inflation means attached to said upper inflatable pouch means and permitting inflation of said upper inflatable pouch means;
- first deflation means attached to said first inflation means and permitting deflation of said upper inflatable pouch means;
- fingertip attachment means connected to the underside of said upper inflatable pouch means suitable for holding the fingertips of the individual;
- thumb attachment means connected to the underside of the upper inflatable pouch means suitable for holding the thumb of the individual;
- arm attachment means connected to said upper inflatable pouch means at the end opposite from said fingertip attachement means and permitting attachment of said upper inflatable pouch means to the arm of said individual;
- lower inflatable pouch means which when attached to the wrist of said individual and inflated extends from the palm of the hand of the individual to the wrist portion of the arm of the individual and when deflated is capable of folding such that both ends are approximately at the palm of the hand;
- wrist attachment means attached to said lower inflatable pouch means and capable of holding said lower inflatable pouch means onto the wrist of said individual and allowing folding of said lower inflatable pouch means when deflated;
- second inflation means attached to said lower inflatable pouch means and permitting inflation of said lower inflatable pouch means;
- second deflation means attached to said second inflation means and permitting deflation of said lower inflatable pouch means;
- flap means attached to and extending from the end of said lower inflatable pouch means nearest the wrist, with sufficient length for wrapping under the palm, around the extended fingertips, over the knuckles and to the top of the wrist;
- flap attachment means attached to and anchoring one end of said flap means in the region of the top surface of the wrist;
- and
- flap length adjustment means attached to said flap means to yield a length which permits the fingers to be straightened when said lower inflatable pouch means is deflated and forces the fingers to bend when said lower inflatable pouch means is inflated.
