FIELD: medical engineering.
SUBSTANCE: method involves continuously measuring electric current amplitude flowing via piezo-ceramic elements of ultrasonic oscillatory system when using mechanical manual tube cross-clamping mechanisms during ultrasonic action applied to suture formation zone. Current amplitude changes are controlled in welding. The condition of current amplitude changes under measurement becoming equal to zero being satisfied, ultrasonic action is to be switched off providing in this way optimum suture quality.
EFFECT: high reliability in sealing various blood containers types.
