Left ventricular auxiliary device system

Abstract

The invention provides a left ventricle auxiliary device system. The left ventricle auxiliary device system comprises a blood drawing intubation tube, a blood transfusion intubation tube and a blood pump. Wherein the blood drawing intubation tube comprises a first port and a second port, a first connecting part is fixed at a first port, and the first connecting part is communicated with the inputend of the blood pump; the blood transfusion intubation tube comprises a third port and a fourth port, a second connecting part is fixed to the third port, and the second connecting part is communicated with the output end of the blood pump. The arterial intubation tube disclosed by the invention is applied to treatment of left heart failure; the blood drawing intubation tube is connected with theinput end of the in-vitro blood pump through the first connecting part; the blood transfusion intubation tube is connected with the output end of the in-vitro blood pump through the second connectingpart, the blood pump works to pump blood deposited in the left ventricle out of the body through the blood drawing intubation tube, then the blood transfusion intubation tube is used for transfusingthe blood back to an arterial system of the patient, and the effect of assisting in blood pumping of the left ventricle is achieved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a left ventricular assist device system. Background technique [0002] The heart is one of the most important organs in the body of vertebrates. Its main function is to provide power for blood flow and transport blood to all parts of the body. The human heart is located in the left lower part of the middle of the thorax. The heart is composed of myocardium. It consists of four chambers: left atrium, left ventricle, right atrium, and right ventricle. The inner wall of the left ventricle is the thickest. These four chambers are for systemic circulation and pulmonary circulation. The only way. The left and right atria and the left and right ventricles are separated by a septum, so they are not connected to each other. There are valves (atrioventricular valves) between the atria and ventricles. These valves allow blood to flow only from the atria into the ventricles, but not back. ...

AI Technical Summary

Problems solved by technology

[0004] The blood extracted by extracorporeal membrane oxygenation equipment is venous blood, so it needs to be sent to the patient's arterial system after extracorporeal membrane oxygenation. Extracorporeal membrane oxygenation equipment makes the entire extracorporeal circulation system complex, bulky and expensive. The patient is under too much pressure and bears greater economic pressure
