Abstract
A suspension aid for appending an above-knee prosthesis to a human body. The suspension aid is integrally formed of a resilient fabric having a warp knit leno, or equivalent, construction. The belt portion of the suspension aid extends substantially horizontally around the intertrochanteric region of the pelvis.
Claims32
An apparatus for appending a prosthesis to a human body, said apparatus comprising:
- a first portion adapted to be secured to the human body;
- and
- a second portion adapted to be secured to the prosthesis,
- said first and second portions comprising a warp knit leno fabric,
- said fabric having a stretch in a substantially horizontal direction of from about 50 to about 200 percent at 30 pounds tension and a stretch in a substantially vertical direction of from about5 to about 100 percent at 30 pounds tension when the apparatus is donned on the erect human body.
An apparatus for appending a prosthesis to a human body, said apparatus comprising:
- a first portion adapted to be secured to the human body;
- and
- a second portion adapted to be secured to the prosthesis,
- said first and second portions comprising a resilient fabric having a stretch in a first direction of from about 50 to about 200 percent at 30 pounds tension and a stretch in a second direction perpendicular to the first direction of from about 5 to about 100 percent at 30 pounds tensions,
- said first direction being substantially horizontal and said second direction being substantially vertical when the first portion is secured to the erect human body.
An apparatus for appending a prosthesis to a human body, said apparatus comprising:
- a first portion adapted to be secured to the human body, said first portion having an endless belt portion dimensioned to extend around the human body;
- and
- a second portion adapted to be secured to the prosthesis,
- said first and second portions comprising a resilient fabric,
- said belt portion defining a body-receiving opening, wherein the size of the body-receiving opening can only be increased by stretching the resilient fabric,
- said fabric having a stretch in a first direction of from about 50 to about 200 percent at 30 pounds tension and a stretch in a second direction of from about 5 to about 100 percent at 30 pounds tension,
- said apparatus adapted to be oriented relative to the human body so that the first direction of the fabric is substantially horizontal and the second direction of the fabric is substantially vertical when the human body is erect.
An apparatus for appending a prosthesis to a human body, said apparatus comprising:
- a belt portion adapted to be secured around the torso of the human body;
- and
- a prosthesis coupling portion adapted to be secured to the prosthesis,
- said belt portion presenting an upper terminal edge,
- said upper terminal edge being substantially straight so that when the apparatus is donned on the human body the upper terminal edge extends around the erect human body in a substantially horizontal fashion,
- said belt portion and said prosthesis coupling portion being formed of a resilient fabric having a stretch in a substantially horizontal direction of from about 50 to about 200 percent at 30 pounds tension and a stretch in a substantially vertical direction of from about 5 to about 100 percent at 30 pounds tension when the apparatus is donned on the erect human body.
