"The DTI 1/4""x1/16"" (2 pcs) is a Double Tube Insert RPM, RPM 20-230 functions as an accessroy for The Heart-Lung Machine HL 20, which is a modular system to drive, control and Monitor extracorporeal circulation. A heart lung machine is used in different surgical and non-surgical specialties. Cardiac surgical procedures requiring cardiopulmonary bypass comprise the vast majority of applications. However, there are some very special procedures that may require a heart-lung machine for extracorporeal bypass support. During these procedures the HL 20 adopts the blood pumping function of the heart while a disposable oxygenator takes over the gas exchange functionalities of the lung."
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.
