Cardiopulmonary bypass devices consist of two main functional units: the pump and the oxygenator. These units remove oxygen-depleted blood from a patient's body and replace it with oxygen-rich blood through a series of tubes, or hoses. Additionally, a heat exchanger is used to control body temperature by heating or cooling the blood in the circuit.
A MAQUET hollow fiber membrane oxygenator. A membrane oxygenator is a device used to add oxygen to, and remove carbon dioxide from the blood.It can be used in two principal modes: to imitate the function of the lungs in cardiopulmonary bypass (CPB), and to oxygenate blood in longer term life support, termed extracorporeal membrane oxygenation (ECMO).
Circuit diagram of a charge qubit circuit. The island (dotted line) is formed by the superconducting electrode between the gate capacitor and the junction capacitance. In quantum computing , a charge qubit (also known as Cooper-pair box ) is a qubit whose basis states are charge states (i.e. states which represent the presence or absence of ...
Schematic of silicone membrane oxygenator. An oxygenator is a medical device that is capable of exchanging oxygen and carbon dioxide in the blood of human patients during surgical procedures that may necessitate the interruption or cessation of blood flow in the body, a critical organ or great blood vessel.
Direct transfusion is a blood salvaging method associated with cardiopulmonary bypass (CPB) circuits or other extracorporeal circuits (ECC) that are used in surgery such as coronary artery bypass grafts , valve replacement, or surgical repair of the great vessels. Following bypass surgery, the ECC circuit contains a significant volume of ...
123D Circuits In-browser circuit design and PCB layout tools. Created by Autodesk, it is free to use, zero-install and web based. There's a limited library of components to use. There are 3 drawing modes: schematics, PCB and breadboard diagram. The PCB editor does not do automatic routing.
It was developed by heart surgeon Dr. Michael DeBakey [4] for blood transfusions [5] while he was a medical student in 1932 and later used by him for cardiopulmonary bypass [6] systems. A specialized nonocclusive roller pump (US Patent 5222880) [7] using soft flat tubing was developed in 1992 for cardiopulmonary bypass systems.
