Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The present invention provides a percutaneous left ventricle assisting device, through which the oxygenated blood in the patient's left ventricle can be directly delivered to the patient's aorta. Such as figure 1 As shown, the auxiliary device includes a drainage tube 1 , a return tube 2 , a first catheter 3 , a second...

Abstract

The invention belongs to the technical field of heart auxiliary equipment, and discloses a percutaneous interventional left ventricle auxiliary device, which comprises a drainage tube, a return tube,a first catheter, a second catheter and a blood pump. The return tube is connected to the outer side of the drainage tube in a sleeving mode, and a cavity is formed between the return tube and the drainage tube. A plurality of groups of second through holes are formed in the tube wall of the return tube; and one end of the first catheter and one end of the second catheter are both nested in one end tube of the drainage tube. The auxiliary device is simple in structure and low in cost. By using the auxiliary device, thoracotomy and open-heart operations do not need to be performed on a patient,and the pain of the patient is reduced; in addition, treatment operation steps are reduced, the treatment time is saved, the treatment difficulty is reduced, and the treatment reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of heart assist devices, in particular to a percutaneous left ventricular assist device. Background technique [0002] A healthy heart relies on its rhythmic and powerful contraction to eject the blood in the left ventricle from the aorta and enter the human arterial system; however, patients with left heart failure suffer from myocardial involvement or even necrosis, losing their strong contractile function and unable to The blood in the left ventricle was fully pumped out, and the cardiac output decreased. The patient eventually died of a series of complications due to insufficient perfusion of peripheral tissues and organs. [0003] At present, for the treatment of left heart failure, there are mainly drug therapy, mechanical circulatory assist device and heart transplantation. Early treatment of left heart failure with drugs can play a certain role, but there are many side effects. While catecholamines...
