Machine for forming a cast of an end portion of an amputated limb

摘要

A machine for forming a negative cast of an end portion of an amputated limb has an outer rigid tubular body; an elastically deformable tubular membrane housed within the rigid tubular body and having its opposite annular end portions fluid-tightly connected to the rigid tubular body, to define a through-duct through which the limb passes and, with the rigid tubular body, a fluid-tight elongated annular chamber with variable volume surrounding the limb; a reference membrane for positioning of the limb within the duct being provided at the outlet of the duct.

主权项

1. A machine for forming a negative cast of an end portion of an amputated limb, the machine comprising an outer rigid tubular body having a substantially vertical axis; an elastically deformable tubular membrane housed within said rigid tubular body along said axis; said membrane comprising opposite annular end portions fluid-tightly connected to corresponding opposite end portions of said rigid tubular body so as to define a through-duct through which said limb passes and, with the rigid tubular body, a fluid-tight elongated annular chamber having a variable volume surrounding the limb; the machine also comprising inlet means for an operative fluid for pressurising said chamber, and axial reference compliant means for a free end of said limb; said membrane, when deformed by the pressurised fluid, having at least one portion protruding outside said outer rigid tubular body and enveloping said limb at least partially.
