Hands-free apparatus to apply a liner to an amputated appendage
View Patent ↗A liner to an appendage of a user includes a base member, a bracket adjustably mounted to the base member to a desired height position, and a plurality of arms pivotably mounted to the bracket. Each arm can include a rotating member, such as a roller ball, coupled to a top end of the arm. The plurality of arms can extend from the bracket in a generally upright position and can support the liner thereon in an inside out position so that the application of downward pressure by the appendage of the user within the plurality of arms permits the arms to pivot outward, thereby allowing the plurality of arms and roller balls to slide the liner around the appendage of the user.
1. An apparatus for applying a liner to an appendage of a user, comprising:
a base member;
an extension extending from a top side of the base;
a bracket mounted at the top side of the base member to the extension;
a pad disposed on and extending upward from a top side of the bracket;
a plurality of arms, each having a lower end pivotably mounted to the bracket and an upper end having a rotatable ball attached thereto, the plurality of arms extending from the bracket in a generally upright position;
an opening formed from the upper end of each of the plurality of arms; and
an elastic band disposed adjacent the lower end of each of the plurality of arms and about an outer side of each of the plurality of arms, the elastic band configured to retain the plurality of arms in the upright position and further permitting the plurality of arms to resiliently move outwardly, causing the opening to expand in size when the user inserts their appendage into the opening,
wherein the plurality of arms are sized and configured to support a liner thereon in an inside-out position so that the application of downward pressure by the appendage of the user within the plurality of arms permits the arms to pivot outward, thereby allowing the plurality of arms and rotatable balls to slide the liner around the appendage of the user.
2. The apparatus of claim 1 , wherein the ball is formed from two separated halves connected by a central connector.
3. The apparatus of claim 2 , further comprising a through hole in the upper end of each of the plurality of arms, the through hole receiving the central connector of the ball therein.
4. The apparatus of claim 1 , wherein the ball includes a hole in opposite ends thereof, the hole receiving tabs disposed on arm extensions extending from an upper end of each of the plurality of arms.
5. The apparatus of claim 1 , wherein the pad is a tubular member.
6. The apparatus of claim 1 , wherein each of the plurality of arms are disposed adjacent an outer portion of the pad and pivot away therefrom.
7. The apparatus of claim 1 , wherein the bracket has a polygonal shape, where a number of sides of the polygonal shape corresponds to a number of arms in the plurality of arms, wherein one of the plurality of arms is pivotably attached to each side of the polygonal shape.
8. The apparatus of claim 1 , wherein the bracket includes one or more set screws for securing a height of the bracket on the extension.
