Abstract
Multipositioning components for a wheelchair including hand, arm and elbow plates and leg, foot and heel components which are form fitted to a patient. And as components of repositionable hand, arm and elbow subassemblies the plates can be extended and aligned for a particular patient or removed and then replaced without disturbing the prior adjustment and alignment of the subassembly.
Claims23
A specialized wheelchair for use by a patient with debilitating conditions of both the upper and lower extremities, and for simultaneous support of said upper and lower extremities, the wheelchair having an arm rail and a lower extension, comprising:
- a formable and repositionable armrest assembly that includes a forearm subassembly having a trough piece, an elbow stop subassembly and a handplate subassembly, the armrest assembly mounted on the arm rail and the forearm subassembly adapted for formation to and alignment with a patient's arm, forearm and hand;
- a formable and repositionable legrest assembly that includes a footplate subassembly with a footplate piece, a knee ab-aductor, a calf plate, and a heel stop yoke, the legrest assembly mounted on the lower extension and the footplate subassembly adapted for formation to and alignment with a patient's knee, calf, foot and heel;
- slide connector means associated with the armrest assembly for slidably removing the forearm subassembly, while maintaining formation to and alignment with a patient's arm, forearm and hand;
- and,
- mounting means for removably securing the legrest assembly to the lower extension to slidably remove the footplate subassembly while maintaining formation to and alignment with a patient's knee, calf, foot and heel.
A specialized wheelchair having an arm rail and a lower extension for attachment of multiposition supports to provide total positioning and support for a paralyzed patient's body and to sustain the upper and lower limbs of wheelchair patients, comprising:
- an adjustable and conformable upper extremity support system for alignment to a patient's upper limb and conformation to a patient's arm, hand and elbow, said upper extremity support system mounted on the wheelchair arm rail;
- an adjustable and conformable lower extremity support system for alignment to a patient's lower limb and conformation to a patient's leg, heel and foot, said lower extremity support system mounted to the lower extension of the wheelchair;
- means for interchanging the upper and lower extremity support systems to alternate wheelchairs without changing the alignments and conformations previously obtained.
