    摘要： A prosthetic system includes a prosthetic valve having a valve body with a shaft defining a flow channel fluidly connectable to an interior of a socket. One or more ports in the valve body are in fluid communication with the flow channel and a membrane is positioned in the valve body. A release button associated with the membrane controls allow air flow into the socket via the one or more ports while air can flow out of the socket via the one or more ports independent of operation of the release button. A one-way valve is connected to the valve assembly that selectively permit air flow out of the socket. A valve insert is mountable on the socket and arranged to couple the valve body to the socket. The valve insert defines an opening configured to allow the shaft to extend through the valve insert and into the socket.

    摘要： A vacuum suspension system includes a pump mechanism operatively connectable to a prosthetic socket. The pump mechanism has a first member and a second member. First and second fluid chambers are located between the first and second members. The second fluid chamber is fluidly separate from the first fluid chamber, and arranged for fluid communication with the socket. An increase in volume of the first fluid chamber mechanically expands the second fluid chamber, which, in turn, creates a vacuum pressure in the second fluid chamber.

    摘要： Prosthetic feet that provide for variable and adjustable stiffness are provided. A foot element can include a tongue portion defined or formed by a slot in the foot element that at least partially separates the tongue portion from a remainder of the foot element. The tongue portion can be operably connected to the remainder of the foot member to increase the stiffness of the foot member or operably disconnected from the remainder of the foot member to increase the flexibility of the foot member. The prosthetic foot further includes a mechanism for adjusting whether the tongue portion is operably connected or disconnected from the remainder of the foot member. The mechanism can be selectively actuated to adjust the stiffness of the foot element in dorsiflexion and/or plantarflexion and/or to adjust the degree to which the tongue portion is allowed to flex relative to the remainder of the foot member.

    摘要： A valve for use with a prosthetic socket includes a body defining an upper opening, a lower opening adapted to be in fluid communication with the socket cavity, and a passageway formed between the openings. A membrane is flexibly seated on the body over the upper opening. The membrane is moveable between a closed position in which the upper opening is sealed such that fluid communication between the upper opening and the lower opening is inhibited, and an open position in which the upper opening is unsealed such that fluid can flow through the passageway. The membrane includes a first part connected to a release element that is operable to move the membrane between the open and closed positions, and a free part operable independent of the first part to move the membrane between the open and closed positions.

    摘要： A vacuum suspension system includes a rigid socket defining a socket wall having exterior and interior surfaces. The socket defines an aperture extending between the exterior and interior surfaces, and has a closed distal end and an open proximal end with an interior cavity defined by the interior surface. A fluid regulator is provided at the aperture and operatively engages the fluid regulator. A pump system includes a pump and a covering for securing over the exterior surface of the socket and carrying the pump. The pump is configured for placement proximate to the fluid regulator and arranged for drawing air from the socket through the aperture. A chamber having a variable volume is formed by a space defined between the exterior surface and an inner surface of the covering proximate to the pump.
