DEVICE FOR ULTRASONIC SEALING AND SEGMENTATION OF TRANSFUSION SYSTEMS Russian patent published in 2022 - IPC A61J1/05 B65B51/22 

FIELD: medical technology.

SUBSTANCE: invention relates to the field of medical technology associated with the collection, storage and processing of blood. The device for ultrasonic sealing and segmentation of transfusion systems consists of a source of ultrasonic action, made in the form of a half-wave piezoelectric system with a welding end having a rectangular radiating surface, placed in a separate movable cylindrical housing with the possibility of its movement inside the outer housing. The movable body with a source of ultrasonic action is mechanically connected to an electromechanical device for moving and pressing, providing the required pressing force to the welding support bar. The welding support bar is mechanically connected to the outer casing and has a rectangular pressing surface. On the clamping surface of the welding support, a cutting protrusion is made with a size not exceeding the wall thickness of the segmented tube.

EFFECT: ensuring reliable sealing of all types of existing hemocontainers of domestic and foreign production with simultaneous separation along the sealing seam of the container and the removed tube system.
