摘要： An embodiment in accordance with the present invention provides a valve including a housing having a top portion and a bottom portion. The top portion of the housing defines a first and second nozzle, and the bottom portion of the housing defines an opening. A diaphragm has an open position and a closed position, and the diaphragm is disposed between the top portion of the housing and the bottom portion of the housing. A first fluid flow path between the first nozzle and the second nozzle is defined by the housing and the diaphragm, when the diaphragm is in the closed position. A second fluid flow path between the opening and the first nozzle is defined by the housing and the diaphragm, when the diaphragm is in the closed position. Such a valve can be used for a number of purposes including hemodialysis procedures.

摘要： An embodiment in accordance with the present invention provides a device and method for hemodialysis including a needle access port having a housing defining a septum, wherein the septum is configured for needle access. Generally, the needle access port will have three septa for communication with valves configured to be anastomosed to a large-diameter blood vessel. The valves are in fluid communication with a flow of blood through the large-diameter blood vessel. The device also includes an elongate tube having a first and a second elongate lumen, wherein a first end of the tube is coupled to the needle access port and a second end of the tube is coupled to the valve. The device can be cleaned by injecting a cleaning fluid into a first septum of the needle access port and extracting it though the second septum of the needle access port.
