Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a novel extracorporeal circulation pipeline.
Background
Extracorporeal circulation is a life support technique in which cardiovenous blood is drained to the outside of the body by a series of special artificial devices, and is returned to the arterial system in the body after gas exchange, temperature regulation and filtration by an artificial method. In the extracorporeal circulation process, the artificial device replaces the functions of the heart and the lung of the human body, so the cardiopulmonary bypass is also called as cardiopulmonary bypass, and the extracorporeal circulation machine is also called as an artificial heart-lung machine. The extracorporeal circulation is performed to maintain the blood supply to the tissues and organs of the whole body when the open heart surgery is performed.
With the development of clinical medicine, the application range of extracorporeal circulation is expanding, and the extracorporeal circulation is not only applied to large vessel surgeries of heart, liver, kidney, lung and the like, but also has remarkable performances in the aspects of life support of patients with tumor treatment and cardiopulmonary failure, and becomes an important technology of clinical medicine.
The body and the blood storage tank, the blood storage tank and the oxygenator, and the oxygenator and the arterial blood pump are connected by pipelines. In addition to the cannula portion, typical venous gravity siphon drainage uses a 12.7mm (1/2 inch) inner diameter tube, a 9.5mm (3/8 inch) inner diameter tube for supplying blood to the aorta, and a 6.4mm (1/4 inch) inner diameter polyvinyl chloride tube for withdrawing blood from the heart. The inner wall of the pipeline is required to be smooth and silicified, and the caliber changing part is required to be tapered, have no fillet and no rough edge so as to reduce resistance, pressure difference and eddy. The children use the thin tube accordingly.
The extracorporeal circulation pipeline is an important component in cardiopulmonary bypass, but the conventional extracorporeal circulation pipeline still has certain defects in clinical application, for example, blood in a venous pipeline cannot be recovered into a blood storage tank in clinical ultrafiltration, so that the problem of waste of the blood is easily caused.
