Title:
【発明の名称】液体送り出しシステム中の空気の検知のための装置及び方法
Document Type and Number:
Japanese Patent JP3321620
Kind Code:
B2
Abstract:
An infusion device includes an infusion pump for delivering a liquid through an infusion conduit from a separate source of the liquid into a patient, a bubble detector for detecting the presence of an air bubble in the infusion conduit, and control circuitry responsive to the bubble detector for determining if the size of the air bubble is unacceptable. The control circuitry is configured to determine if during the time the air bubble is detected it advances a distance indicative of the unacceptable size, one embodiment counting the steps of a linear peristaltic infusion pump for that purpose.
