Claim 22:
23. A fluid transfer device, comprising:
a housing including a port that can connect to a needle that can be inserted into a patient;
first and second channels at least partially in the housing, the first channel being separate from the second channel; and
a valve in communication with the first channel, the valve configured to allow a first volume of fluid to flow from the patient toward the valve and to automatically close to prevent the first volume of fluid and any contaminants therein from substantially contaminating a second volume of fluid received into the second channel of the fluid transfer device,
the valve configured to automatically close after at least a portion of the first volume of fluid has been received from the patient and pressure equalizes between an inner volume of the fluid transfer device and a portion of the patient to which the needle is inserted.
