Abstract
An infusion pump for regulating the administration of intravenous fluids to a patient. The infusion pump includes a pump housing for holding the pumping mechanism, and a door for holding the IV tubing set in operably position relative to the pumping mechanism. The upper surface of the pump housing has a notch formed therein, and the upper surface of the door is positioned under the notch when the door is closed. The notch is sized and shaped so as to closely grip the IV tubing assembly around a portion of its circumference, so that liquid dripping down along the exterior of the IV tubing set from above the notch tends to be shunted away from the IV tubing. Liquid dripping through the notch tends is diverted onto the upper surface of the door and away from the pumping mechanism.
