DEVICE FOR EXTRACORPORAL CIRCULATION AND METHOD OF ITS ASSEMBLY Russian patent published in 2018 - IPC A61M1/02 

FIELD: medicine.

SUBSTANCE: group of inventions refers to cardiovascular surgery, can be used, in particular, for surgery on the aorta. When assembling the device for extracorporeal circulation, connect the main output from the arterial filter-trap with the tee, which is then connected to the main arterial blood line and the additional arterial blood line. Said blood lines are supplied from the sterile zone of the operating table, the main arterial blood line is supplied directly from the sterile zone of the operating table, and the additional arterial blood line is conducted through an additional pump. At a distance of at least 200 cm from the first tee, the main arterial blood line and the additional arterial blood line are connected by a communication jumper no longer than 50 cm long. Communication jumper is connected by additional tees with the main and additional arterial blood lines and an additional arterial blood line and establish switching clamps on the extracorporeal blood lines in the area of the communication bridge. One switching clamp is installed on the communication jumper between the main arterial blood line and an additional arterial blood line. Another switching clamp is installed on an additional artery blood line. And one more switching clamp is installed on the communication jumper between the additional arterial blood line and the additional arterial blood line. Switching clamps are installed on sections of the main blood line, adjacent to the communication bridge on both sides. On the sections of the additional blood line, which also adjoin the communication bridge on both sides, switch clamps are installed.

EFFECT: group of inventions ensures the minimization of the time of ischemia in vascular pools, reducing the risk of air embolism and reducing the level of hypothermia due to a change in the course of surgical intervention of the option of artificial circulation with separate blood supply of several arterial pools and with connection to perfusion without opening the perfusion loop at least one additional arterial pool.
