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.
