A self priming tubing set for infusing a medical solution from an infusion device to a patient includes a supply tube (12), an air/particle filter (16), and a restrictor tube (18). The air/particle filter is adapted to remove air, particularly air contained in the supply tube at the initiation of fluid flow. The air/particle filter also removes particles from the medical solution. The restrictor tube is adapted to reduce the pressure of the medical solution from the delivery pressure of the infusion device to about a mean venous pressure of the patient. The length and inside diameter of the restrictor tube are calibrated to achieve a desired pressure drop dependent on design criteria of the system. The tubing set also includes a slide clamp (14) for closing fluid flow from the supply tube and a connector (20) for connection to a patient interface such as a hypodermic needle or cannula. <IMAGE> |
