Abstract
Waterproof covers for prosthetics. The waterproof cover may be used with a prosthetic hand or other prosthetics or orthotics. The waterproof cover protects the interior components of the prosthetic. The cover may be flame-resistant. The cover may include two layers. An example cover may have an external layer of fabric knitted from aromatic polyamide (meta-aramid) fiber such as NOMEX® yarn and an interior polyurethane or silicone layer. Another example cover may have a single layer, made of woven aromatic polyamide fiber such as NOMEX or Kevlar® with a silicone coating on one or both sides. For a prosthetic hand, the cover may extend between a thumb and a palm.
