ABSTRACT:
A method and apparatus for forming a prosthetic socket using a vacuum tube assembly for vacuum sealing a layer of plastic material onto a molded cast to form a prosthetic socket. The vacuum tube assembly includes a cylindrical shaft for providing an air path for the vacuum tube assembly between the prosthetic cast and a suction device. The cylindrical shaft includes a connection device attached to one end of the cylindrical shaft, wherein the connection device is used for affixing the vacuum tube assembly to an attachment device on the prosthetic socket. The attachment device is formed within the prosthetic socket and is the component which connects the prosthetic socket to an artificial limb shaft. A reciprocating cover is also provided on one end of the cylindrical shaft for covering the connection device, so that the reciprocating cover abuts the prosthetic socket when the connection device is affixed to the attachment device. The reciprocating cover is spring-loaded against the cylindrical shaft so that a force is exerted against the reciprocating cover toward the prosthetic socket, wherein a force must be exerted against the cover sufficient enough to overcome the spring-load in order to allow access to the connection device.
