Active prosthetic socket
An active prosthetic socket including a prosthetic socket shaped to fit a residual limb. An active adjustment system is integrated with the prosthetic socket and is configured to dynamically adjust the fit of the active prosthetic socket to the residual limb of a user during ambulation or motion.
1. An active prosthetic socket comprising:
a prosthetic socket shaped to fit a residual limb; and
an active adjustment system integrated with the prosthetic socket including:
four actuator bladders located at a rounded bottom end of the prosthetic socket;
at least two active bladders located at a middle of the prosthetic socket and at least two active bladders located at the top of the prosthetic socket, each of the active bladders fluidically coupled only to one of the four actuator bladders; and
the four actuator bladders configured to be compressed as a prosthetic leg and foot attached to the prosthetic socket strikes the ground causing fluid in the four actuator bladders to be transferred to the two active bladders at the middle of the prosthetic socket and the two active bladders at the top of the prosthetic socket such that the active bladders compress on a residual limb to provide a snug fit of the prosthetic device.
2. An active prosthetic socket comprising:
a prosthetic socket shaped to fit a residual limb; and
an active adjustment system integrated with the prosthetic socket including:
one actuator bladder located at a bottom end of the prosthetic socket;
at least two active bladders located at a middle of the prosthetic socket and at least two active bladders located at a top of the prosthetic socket, each of the active bladders fluidically coupled only to the one actuator bladder; and
the one actuator bladder configured to be compressed as a prosthetic leg and foot attached to the prosthetic socket strikes the ground causing fluid in the one actuator bladder to be transferred to the two active bladders located at the middle of the prosthetic socket and the two active bladders at the top of the prosthetic socket such that the active bladders compress on a residual limb to provide a snug fit of the prosthetic device.
