Abstract
Systems and methods for sensing bubbles during fluid infusion are disclosed. An infusion device comprises a pathway, at least one pump adjacent the pathway, first and second bubble sensors positioned adjacent the pathway, and a processor. The pathway is adapted to receive tubing. The pump alters the pathway to pump fluid through the tubing when the tubing is received in the pathway. The second bubble sensor is spaced from the first bubble sensor. The first and second bubble sensors are configured to detect a bubble in the fluid being pumped through the tubing. The processor is programmed to determine that the first bubble sensor detects a bubble, determine whether the second bubble sensor detects a bubble, and to generate an alarm condition only when the first bubble sensor and the second bubble sensor detect the same bubble.
