Air Embolism Protection (AEP) System including a bubble/level monitoring kit. This AEP is an accessory for The Heart-Lung Machine HL 20 , which is a modular system for regulation, control and monitoring of the extracorporeal circulation. Its purpose is the support and maintenance of the extracorporeal blood circulation and is used during cardiac surgeries.
A mains electricity (AC-powered) device designed to detect air bubbles in blood returned to the body from the extracorporeal circuit of a cardiopulmonary (heart-lung) bypass system, and to detect when blood falls below acceptable levels, typically in the venous drip chamber. The device typically consists of an electronic unit and ultrasonic sensors; it usually triggers alarms and activates automated mechanisms to turn off the blood flow when bubbles are detected or an abnormal fluid level occurs. It is typically an integral part of the cardiopulmonary bypass system.
