Abstract
A rigid support mounted to protect the site of a connection to a catheter or other in-dwelling treatment assembly. In a forearm cast assembly for a dialysis catheter, a hinged frame is retained to the arm with adjustable elastic strap anchors at the elbow and hand. Top and bottom perforated frame sections are held together with hook and loop hinges and closure fasteners. A variety of detachable, cushioned liners mount to the interior frame surfaces to prevent abrasion or dislodgment of the treatment assembly. The frames are constructed to permit limb movement within the cast with minimal impediment to limb movement about the body. Alternative single and double shell frames are also disclosed which include adjustable harness straps and adhesive retainers to accommodate a variety of mounting sites.
