ClearLine IV, (the new product name of AirPurge System - Control Unit), is intended for detection and automatic removal of air in intravenous lines during administration of intravenous solutions, blood and blood products. It is indicated for use in the Operating Room and post anesthesia care areas. The ClearLine IV is placed distal to I.V. bags using gravity feed or pressure, and may be used with or without fluid warmer.
A mains electricity (AC-powered) device designed to identify air bubbles and/or foam in blood returned to the body [usually through an arteriovenous fistula (AVF)] by the extracorporeal blood circuit of a haemodialysis system. It may detect the air bubbles/foam using either ultrasonic sensors (i.e., detecting changes in acoustic density), or less frequently using photoelectric sensors (e.g., a photocell). If bubbles/foam are detected, the device usually triggers alarms and activates automated mechanisms to stop the infusion.
