First Claim
1. A medical valve device for use with a blood treatment set, the device comprising:
- a tubular fitting including;
first and second chambers,a first end portion for engagement and communication with a first port, the first end portion communicating with the first chamber,a second end portion for engagement and communication with a second port, the second end portion communicating with the second chamber, anda generally central portion having an internal flexible barrier having a slit extending between the first chamber and the second chamber; and
an actuating member in rotatable engagement radially around the fitting central portion and including;
an exterior portion for manual movement of the actuating member, andan inner surface generally in contact with the fitting central portion, the inner surface including at least a first flat,wherein the actuating member is moveable to a first position whereby the first flat is positioned relative to the slit to compress the fitting central portion and open the slit to permit communication between the first and second chambers, and the actuating member is moveable to a second position whereby the first flat is positioned relative to the slit to compress the fitting central portion to close the slit to prevent communication between the first and second chambers.

Abstract
A flexible valve for a blood treatment set. A flexible fitting including a first chamber, a second chamber, and a slit barrier connecting the first chamber and second chamber and positioned therebetween. An actuating member is positioned in rotating engagement with the slit barrier that is moveable from a first rotational position, in which the slit is closed, to a second position, in which the slit is open. The flexible valve is attachable to a port of a blood treatment chamber. A user opens the valve by rotating the actuating member from a first position to a second position and closes the valve by rotating the valve from the second position to a first position.
