Abstract
The invention relates to prosthetic training devices for attachment to the residual limb of transradial or transhumeral amputee.
Claims22
A prosthetic training device for attachment to a residual limb of a transradial amputee, said device comprising:
- (a) at least one elongate rigid support shaft;
- (b) a connector configured to removably receive one or more weights and/or a virtual reality (VR) controller or other positional sensor, wherein said connector is engaged with and secured or securable in a fixed position along the distal part or half of said support shaft(s);
- (c) a first securing strap comprising a first end and a second end, wherein said strap is engaged with and secured or securable in a fixed position along the proximal part or half of at least one of said support shaft(s), and wherein said strap is configured to selectively secure the first end to the second end around the residual limb of a user at a circumferential position below the elbow;
- (d) a second securing strap comprising a first end and second end, wherein said strap is flexibly tethered or tetherable to said first securing strap and/or the proximal part or half of at least one of said support shaft(s), and wherein said strap is configured to selectively secure the first end to the second end around the residual limb of a user at a circumferential position above the elbow;
- and
- (e) a forearm retainer configured to maintain a volumetric fit over the residual limb of a user via adjustable circumferential force, wherein said retainer is engaged with and secured or securable in a fixed position on at least one of said support shaft(s) between said connector and said first securing strap.

A prosthetic training device for attachment to a residual limb of a transhumeral amputee, said device comprising:
- (a) at least one first elongate rigid support shaft;
- (b) at least one second elongate rigid support shaft, wherein the distal end of each of said at least one second support shaft is hingedly connected to the proximal end of the corresponding first support shaft via an articulated and optionally lockable joint;
- (c) a connector configured to removably receive one or more weights and/or a virtual reality (VR) controller or other positional sensor, wherein said connector is engaged with and secured or securable in a fixed position along the distal part or half of said first support shaft(s);
- (d) a securing strap comprising a first end and a second end, wherein said strap is engaged with and secured or securable in a fixed position along the proximal part or half of at least one of said second support shaft(s), and wherein said strap is configured to selectively secure the first end to the second end around a circumferential position of the residual limb of a user;
- (e) a body harness flexibly tethered or tetherable to said securing strap and/or the proximal part or half of at least one of said second support shaft(s) and configured such that, in use, said harness wraps around the shoulder of the residual limb and around the torso of a user;
- and
- (f) an arm retainer configured to maintain a volumetric fit over a portion of the residual limb of a user via adjustable circumferential force, wherein said retainer is engaged with and secured or securable in a fixed position on at least one of said second support shaft(s) between said articulated joint and said securing strap.
