Abstract
A blood bag sterile connection method includes the following steps: 1) placing blood bag tubes above the wire box, clamping positions to be cut by using the vascular clamps, and simultaneously moving the two vascular clamps in opposite directions; 2) heating the composite metal wire, and cutting the blood bag tubes by using the composite metal wire; 3) after cutting the blood bag tubes, aligning the blood bag tubes to be connected; 4) moving the two vascular clamps towards each other, rolling away the used composite metal wire, and rolling out a new composite metal wire; 5) connecting the blood bag tubes by heating the composite metal wire, and simultaneously moving the two vascular clamps towards each other; and 6) returning the wire box to the initial position, taking out the connected blood bag tubes, and returning the vascular clamps to the initial positions.
