Patent ID: 8357143

Claim:
A medical product configured for use in a medical system comprising: a first subsystem having a first connection portion and a second subsystem having a second connection portion, at least one of the first and second subsystems containing a medical fluid, the medical product comprising a connector configured to connect the first and second subsystems to each other to permit transport of the medical fluid from one of the first and second subsystems to the other of said first and second subsystems, the connector comprising: including a valve device; a first connection pipe connected to the valve device and configured to be connected to the first connection portion of the first subsystem; and a second connection pipe connected to the valve device and configured to be connected to the second connection portion of the second subsystem; the valve device comprising a first part and a second part, said first and second parts being movable in relation to each other to permit an opening movement from a closed stable position, said closed stable position preventing fluid communication between the first connection pipe and the second connection pipe, to an open stable position, said opening movement to the open stable position forming a channel permitting fluid communication between the first connection pipe and the second connection pipe, wherein the connector comprises at least one small passage permitting, in the closed stable position, an introduction of a sterilizing gas, said at least one small passage being configured to permit the sterilizing gas to contact wall surfaces defining the channel, wherein the first part comprises a housing through which the channel extends, said housing comprising a cylinder forming an inner chamber extending transversally to and crossing the channel; wherein the second part comprises a piston, said piston being movable in the inner chamber between the closed stable position closing the channel and the open stable position, in which the channel is open by means of a recess in the piston, the cylinder has a primary end and a secondary end and the piston has a primary end and a secondary end, said primary end of the piston protruding from the primary end of the cylinder in the closed stable position and said secondary end of the piston protruding from the secondary end of the cylinder in the open stable position.
