Auxiliary pump blood catheter pump

Abstract

The invention provides an auxiliary pump blood catheter pump, which relates to the technical field of medical apparatus and instruments, and comprises a fixed support assembly, a fluid tube and an axial flow impeller, a blood inlet and a blood outlet are formed in the fluid pipe, the fixed supporting assembly is connected with the pipe wall of the fluid pipe, and the fixed supporting assembly has a reversible unfolding posture and a reversible storage posture; and the product can be implanted into a blood transfusion organ through a catheter, large surgical operations such as thoracotomy are not needed, trauma is small, and recovery is fast. When the device is applied to the aorta connected with the left ventricle, the blood inlet of the fluid tube is communicated with the left ventricle, and the device is used for improving the hemodynamic performance in the heart, increasing the cardiac output or assisting a high-risk cardiac surgery; when applied to the descending aorta, the product can improve the kidney perfusion pressure in the descending aorta and is used for preventing renal failure caused by acute heart failure; when applied to the interiors of superior vena cava, inferior vena cava or pulmonary arteries and the like, the pressure in blood vessels can be increased, and blood perfusion of all blood transfusion organs is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary blood pump catheter pump. Background technique [0002] The heart is an important organ that provides power for blood circulation in the human body. The heart is divided into left and right parts, each containing a ventricle and an atrium. Between the left ventricle and the right ventricle through the interventricular septum, between the left atrium and the right atrium through the atrial septum. The direction of blood flow between the left atrium and left ventricle is regulated by the mitral valve. A healthy mitral valve ensures that oxygen-rich blood flows from the left atrium to the left ventricle, from which it pumps to arteries throughout the body. The direction of blood flow between the right atrium and right ventricle is regulated by the tricuspid valve. The tricuspid valve does contain carbon dioxide-rich venous blood, which flows from the right a...
