Filed:

Feb 1, 2022

Appl. No.:

17/590280

Inventors:

- Holliston MA, US

International Classification:

A61F 2/66

Abstract:

A prosthetic foot includes a foot portion and a switching adapter. The switching adapter includes a first member coupled to the foot portion, a second member, a third member interposed between the first member and the second member, and a locking mechanism. The third member has a first side wall and a second side wall larger in length than the first side wall. The third member is configured to rotate relative to the first member and the second member towards a first position, thereby placing the prosthetic device in a walking mode. The third member is further configured to rotate relative to the first member and the second member towards a second position, thereby placing the prosthetic device in a running mode. The locking mechanism is configured to rotate with the third member in response to rotation of the third member.

International Classification:

A61F 2/80
A61F 2/78
A61F 7/00
A61F 5/01

Abstract:

A prosthetic socket cooling system and method includes a strap for coupling about a limb fitted with a prosthetic socket. One or more thermally conductive heat spreaders are associated with the strap and may be at least partially seated underneath the prosthetic socket. A heat extraction subsystem is coupled to at least one of the lengthy heat spreaders and carried by the strap. In one version, heat spreaders may form sections of the strap.
