摘要:
A control system is adapted for use in association with a therapeutic motion and splinting device. The therapeutic device has at least one component that is monitored. The system comprises the steps of defining the range of motion, defining the maximum reverse on load, monitoring the reverse on load and moving the device through its range of motion. A first and second maximum limit of range of motion in a first and second direction are respectively defined. A maximum reverse on load is defined and is monitored whereby the deformation of the at least one component is monitored and the load created is interpreted. The device is cycled between a first and second position defined by one of the first maximum limit and the maximum reverse on load and one of the second maximum limit and the maximum reverse on load respectively.

An apparatus and method for securing a prosthesis to the residuum of a limb of an amputee and for providing pressure therapy to the residuum so as to manage fluid within the residuum. The apparatus includes a socket (504) shaped to receive a residuum of a limb (502) of an amputee and configured to connect to a prosthetic limb. The socket (504) forming a chamber (505) between the socket (504) and the residuum (502) when the socket receives the residuum. The apparatus also includes a pressure control device (520) operably connected to the chamber (505) and capable of creating a positive pressure and a negative pressure within the chamber to provide pressure therapy to the residuum, as well as provide securement of the socket to the residuum. The apparatus may also include a liner surrounding at least a portion of the residuum. The control device adjust pressure within the chamber based on manual and automatic inputs.

A hypobarically-controlled artificial limb for amputees includes a single socket (60) with a volume and shape to receive a substantial portion of the residual limb(14). A liner (92) with a volume less than the residual limb is donned over the residual limb, with the liner (92) tensioned into a total contact relationship with the residual limb (14). A sealed cavity (62) is formed between the socket (60) and the liner (92). A vacuum source (70) is connected to the socket cavity (60) thereby drawing the residual limb and liner into firm and total contact with the socket. To compensate for some air leakage past the seal, there is a mechanism to maintain the vacuum in the cavity. An osmotic membrane (100) encases the residual limb and creates a space between the residual limb and the liner. The osmotic membrane (100) allows passage of water only in one direction: from the residual limb toward the liner. Vacuum may be applied to the space (102) between the osmotic membrane (100) and the liner (92) to assist in wicking perspiration away from the residual limb.

A hypobarically-controlled artificial limb for amputees includes an outer socket, a flexible, compressible inner socket within the outer socket with a cavity for receiving the residual limb, a space between the inner socket and the outer socket, a vacuum source connected to the cavity, a positive pressure source connected to the space, a regulator for controlling the vacuum source and positive pressure source, and a seal for making an airtight seal between the residual limb and the socket. Another embodiment includes a semi-compressible molding material in the space to mold to the contours of the residual limb under the influence of vacuum and/or positive pressure. Another embodiment includes a positive mechanical interlock between the inner socket and the outer socket.
摘要:
A foot prosthesis (100) having improved rollover and stability. The prosthesis (100) includes a first plate (130) and a mounting block (140) having a mounting portion configured to be coupled to a user of the prosthesis (100), an attachment portion and a gap portion (147), with the mounting block (140) attached to the first plate (130) at the attachment portion with a gap (147) between the mounting block gap portion (147) and the first plate (130). Also included is a resilient element (150) positioned at least partially within the gap (147), the resilient element (150) configured generally to dissipate stress in the first plate (130) and control deflection between the first plate (130) and the mounting block (140). The mounting block (140) may be substantially rigid with the area of the first plate (130) attached to the mounting block (140) becoming substantially rigid while the remainder of the first plate (130) is at least partially flexible. The resilient element (150) may be interchangeable to adjust performance of the prosthesis (100).
