PROSTHETIC DEVICE UTILIZING ELECTRIC VACUUM PUMP

摘要

According to the embodiments described herein, prosthetic devices can include a prosthetic socket, a vacuum passage, and an evacuation device. The interior of the prosthetic socket can be adapted to receive a residual limb. The vacuum passage can extend through the side wall of the prosthetic socket and into the interior of the prosthetic socket. The evacuation device can include an electrically powered vacuum pump contained within a housing. The housing can be attached to the side wall on the exterior of the prosthetic socket. The electrically powered vacuum pump can be in communication with the vacuum passage. The electrically powered vacuum pump can draw air from the interior of the prosthetic socket, while the residual limb is received within the interior of the prosthetic socket, to evacuate the prosthetic socket.

主权项

1. A prosthetic device, comprising:
a prosthetic socket comprising a side wall extending from a distal end of the prosthetic socket to form an interior and an exterior of the prosthetic socket, wherein the interior of the prosthetic socket is adapted to receive a residual limb; a vacuum passage extending through the side wall of the prosthetic socket and into the interior of the prosthetic socket; and an evacuation device comprising an electrically powered vacuum pump and a source of electric power both contained within a common housing, wherein:
the common housing is attached to the side wall on the exterior of the prosthetic socket,the electrically powered vacuum pump is in communication with the vacuum passage, andthe electrically powered vacuum pump draws air from the interior of the prosthetic socket, while the residual limb is received within the interior of the prosthetic socket, to evacuate the prosthetic socket.
