Abstract:
A syringe pump infusion control set comprising:a coupling junction having a bottle port, a patient port, and a syringe port;a normally closed, high cracking valve having an inlet side and an outlet side and being operable in response to negative high cracking pressure at the outlet side, the high cracking valve outlet side being coupled to the bottle port;a low cracking valve having an inlet side and an outlet side and being held open in response to positive low cracking pressure at the inlet side, the low cracking valve inlet side being coupled to the patient port; andthe syringe port of the junction being adapted to couple to a syringe by which to selectively apply negative high cracking pressure and positive low cracking pressure at the syringe port whereby application of negative high cracking pressure at the syringe port draws fluid at the inlet side of the high cracking valve into the syringe while the low cracking valve remains closed and application of positive low cracking pressure at the syringe port injects fluid from the syringe to the outlet side of the low cracking valve while the high cracking valve remains closed.
