1. A method for catheter line disinfection, comprising:
connecting a first catheter to a second catheter using a transfer valve comprising a valve body comprising a first through hole configured to fluidly communicate with the first catheter, a second through hole configured to fluidly communicate with the second catheter, a flush hole positioned between the first through hole and the second through hole, and a generally cylindrical valve core comprising a rounded notch;
flushing fluid from the second catheter through the flush hole while sealing off fluid communication with the first through hole, said flushing comprising directing fluid flow between the second through hole and the flush hole by way of the rounded notch;
flowing fluid between the first through hole and the second through hole, by way of the rounded notch, while sealing off fluid communication with the flush hole; and
removing a cover from the second through hole prior to connecting the second through hole to the second catheter, the cover including a feature that prevents rotation of said cylindrical valve core.
