Abstract

A suspended sleeve assembly includes a suspension stand and a compression sleeve. An upper portion of the compression sleeve is attached onto the suspension stand, but a lower portion of the compression sleeve is unattached from the suspension stand. The suspended sleeve assembly can also include a support stand. The suspended sleeve assembly can be used to shape a prosthetic socket. The compression sleeve applies a circumferential pressure onto the prosthetic socket as the prosthetic socket is being inserted into the compression sleeve as a patient steps into the compression sleeve and applies at least a portion of body weight to the compression sleeve. The prosthetic socket can be heated and shaped by hand, so that it fits the residual limb of the patient. The suspended sleeve assembly can also be used to shape other prosthetic components, such as a negative plaster cast.

Claims14

Dependent claims

A method for shaping a prosthetic socket, comprising:

providing a compression sleeve comprising:
an upper portion attached to a suspension stand,
a lower portion that is unattached from the suspension stand, and
a receptacle;
allowing a patient wearing the prosthetic socket to step into the compression sleeve so that at least a portion of the prosthetic socket is enclosed in the receptacle of the compression sleeve;
adjusting a height of the suspension stand based on a height of the patient;
and
heating the prosthetic socket to a temperature in a range from about 70° C. to 150° C.,
shaping the prosthetic socket through the compression sleeve to a residual limb of the patient that is surrounded by the prosthetic socket,
wherein the compression sleeve is configured to allow the prosthetic socket to be shaped based on a shape of the residual limb of the patient wearing the prosthetic socket,
wherein the receptacle is sized and configured to apply circumferential pressure onto the prosthetic socket during the shaping the prosthetic socket,
wherein the suspension stand comprises:
a base;
a support pole;
and
a receiver, wherein a portion of the compression sleeve is configured to be attached to the receiver,
wherein the prosthetic socket comprises:
a first portion configured as a conical cup comprising a material having a first pliability at a temperature in range from about 70° C. and 150° C.;
and
a second portion configured as a base portion having a second pliability which is less than the first pliability.
