Problems solved by technology

Acute myocardial infarction, due to myocardial injury and subsequent scarring, leads to heart enlargement and heart failure, especially patients with anterior wall myocardial infarction combined with ventricular aneurysm are more prone to heart failure, which not only affects the quality of life of patients, but also causes huge Financial burden on family and society
[0003] For patients with heart failure, in addition to drug treatment, surgery can also be used, but because the patients who need surgery are in critical condition, and the surgical trauma is relatively large, the requirements for the surgeon are relatively high, and the clinical application is limited.

Abstract

The invention discloses a device and method for manufacturing an isolating layer in cardiac tamping. The device comprises an assembly device, an umbrella-shaped framework structure, an isolating membrane and reinforcing ribs. The assembly device comprises an upper cover, a lower cover and a plurality of locating bolts. The umbrella-shaped framework structure comprises a plurality of umbrella-rib-shaped joint rods. One ends of the umbrella-rib-shaped joint rods are evenly distributed in the peripheral direction of a base cylinder. The other ends of the umbrella-rib-shaped joint rods extend outwards in a radial mode to form a cone. The isolating membrane covers the inner surface or outer surface of the cone formed by the umbrella-rib-shaped joint rods. The reinforcing ribs are arranged between the umbrella-rib-shaped joint rods and the isolating membrane. The high-molecular isolating membrane and the umbrella-shaped framework structure are combined to form the umbrella-shaped isolating layer by heating, pressing and fusing the high-molecular reinforcing ribs. The cardiac tamping effectively isolates the ventricular volume via the isolating layer, and therefore the ventricular volume is effectively reduced, the ventricular tension is reduced, and then ventricular remodeling and the cardiac function of patients are improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device and method for making an isolation layer in a heart tamponade. Background technique [0002] In recent years, the treatment of heart disease has made great progress, but heart failure, one of the final outcomes of all heart diseases, has always threatened human health, and the 5-year survival rate is even worse than that of some malignant tumors. There are many causes of heart failure, one of the most common causes being acute myocardial infarction. Acute myocardial infarction, due to myocardial injury and subsequent scarring, leads to heart enlargement and heart failure, especially patients with anterior wall myocardial infarction combined with ventricular aneurysm are more prone to heart failure, which not only affects the quality of life of patients, but also causes huge economic burden on the family and society. [0003] For patients with heart failure, in addition t...
