A controlled apparatus for withdrawing fluids from a patient or for administering medication to a patient, or both, which controlled apparatus may be remotely and/or automatically controlled. The apparatus includes a manifold and cannula for connecting the manifold to a patient, one or more syringes connected to the manifold, a pump for pumping liquid into and out of the manifold and a controller for controlling the operation of the syringes and the pump. A method of using the apparatus is also provided. The controlled apparatus is especially useful for the programmed withdrawal of blood from a blood vessel of a patient.

A method of taking a plurality of blood samples from a blood vessel of a patient, using a like plurality of syringes therefor, said method comprising: (a) connecting a manifold to said blood vessel; (b) pumping at a slow rate anticoagulant through said manifold into said blood vessel; (c) interrupting pumping step (b) and then drawing from said patient into said manifold at a rapid rate blood for said sampling; (d) actuating a separate one of said plurality of syringes to remove from said manifold a sampling of blood; (e) discontinuing the actuation of each such syringe prior to the complete filling thereof with blood; (f) then flushing said manifold of blood by pumping therein at a rapid rate anticoagulant; (g) then reactuating the partially filled syringe to draw from said manifold anticoagulant; and (h) then returning to step (b) to operate another syringe to take another blood sample.
