Abstract
A biological fluid collection and dispensing apparatus for attachment to a sealed test tube includes a pump and a housing, the housing having a movable portion, and a cannula assembly mounted relative to the housing. Biological fluid is withdrawn from a patient and flows through the pump and housing into the interior of the sealed test tube. The pump is actuated initially to release a delivery conduit and to move the housing such that part of the cannula assembly pierces the test tube seal. The pump is thereafter actuated to pressurize the contents of the test tube such that aliquots may be dispensed through the cannula assembly and delivery tube.
