Prosthetic Liner Assist Device

Abstract

A device for assisting amputees donning prosthetic liners uses a plurality of elongate fingers, radially biased about a central space, to support the liner against the residual limb as the liner is applied. Rollers on each finger provide a frictionless traversal of the device by the limb as the limb is inserted into the central space. Hinged connection of the fingers to a base supporting the fingers, as well as hinges allowing each finger to bend, ensure that engagement between the rollers and the liner is maintained during both limb insertion and withdrawal. Elastic bungees or shock cords joining the fingers provide the radial biasing to the fingers toward the central space.
