Background technology
External film lung oxygen closes (Extracorporealmembraneoxygenation, ECMO) extracorporeal circulation technology (CPB) is originated from, it is treat reversible respiratory insufficiency by extracorporeal blood gaseous interchange at first, then become the temporary bodyfixed frame of the cardiorespiratory failure that the various reason of out operating-room causes, and achieve certain good clinical therapeutic efficacy.
It is applied to heart death organ donation (donationaftercardiacdeath by reported first ECMO from 1989; DCD), since, clinical study shows that the protection of transplant organ Warm ischemia injury and repair are subject to the extensive concern of medical circle by ECMO. ECMO can alleviate DCD transplant organ Warm ischemia injury, improves and obtains organ mass, thus expand and obtain organ utilization ratio; And demonstrate good application prospect in DCD filed of organ transplantation.
ECMO working process is exactly that body inner blood is first drained to storage blood tank in simple terms, then by mechanical pump, blood pump is entered oxygenator, through film lung by blood oxygenation, discharge CO2 and again by another defeated body of road back of pipeline after heating. And its DCD abdomen organ contribute in application, the abdomen organ that intubate perfusion (shutoff aorta abdominalis upper and lower ends) is set up before organ obtains temporarily moves circulation path, utilize ECMO that abdomen organ carries out the hemoperfusion of effective oxygen conjunction, and then carry out organ acquisition, hypothermia perfusion and the preservations such as liver kidney, thus shortening heat Ischemia Time to the full extent, alleviate transplant organ Warm ischemia injury, improve and obtain organ mass, expand and obtain organ utilization ratio. We are found by searching document, there is no the ECMO special perfusion cannula of belly local circulation on clinical at present. The clinical general non-dedicated perfusion cannula (without balloon design) using routine. Specific operation process often needs anatomical isolation bilateral iliac artery, side insertion perfusion cannula, ligation iliac vessels; The conduit of band air bag need to be inserted to place's shutoff aorta abdominalis upper end, thoracoabdominal aorta boundary in another side, airbag aeration ligation iliac vessels. Whole operating process is time-consuming longer, and technical requirements is complicated. Not only bring inconvenience to clinical application operation, and shorten the hot Ischemia Time of transplant organ with being unfavorable for maximum degree and ensure to obtain the quality of organ. Therefore, on clinical, need ECMO abdomen organ's local circulation perfusion dedicated conduits badly.
