Oxygenator System
WEGO Medical
The venous blood with low oxygen content is oxygenated into arterial blood with high oxygen content to meet the needs of the patient during surgery.
WG2500A
Oxygenator System
Extracorporeal circulation is a life support technology that uses pipes to connect oxygenators and other consumables and equipment to drain venous blood outside the body, perform gas exchange, adjust temperature and filter artificially, and then inject it back into the arterial system of the body.
Overview
WEGO oxygenator is an artificial organ that can exchange blood and gas. It integrates the functions of oxygenation, temperature change, blood storage, filtration, and blood recovery. Its main function is to oxygenate venous blood with low oxygen content. Becomes arterial blood with high oxygen content to meet the needs of the patient during surgery. 2021: Through comparison and application with imported products in total thoracic minimally invasive cardiac surgery, Weigao membrane oxygenator has no significant difference from imported products in terms of VAVD use, oxygenation performance, carbon dioxide removal and blood compatibility.
It uses hollow fibers with micropores as the medium for gas and blood exchange. The hollow fibers carry blood outside and gas inside. Gas and blood exchange O2 and CO2 through diffusion on both sides of the hollow fiber membrane wall, avoiding the direct contact between blood and gas. contact, reducing the denaturation of serum proteins.
Thermostat: It adopts PET capillary tube. When the product is used, blood flows outside the capillary tube and water flows inside. The temperature of the water is adjusted through an external variable temperature water tank, thereby achieving blood temperature control.
