CUTTING A COLLAPSIBLE TUBE FOR BIOPHARMACEUTICAL USE

摘要

The invention relates to a method for closing and cutting a collapsible tube, wherein a cutting member (2) and a pinching closing device (1) are provided for cutting into two sections (3a, 3b), each with two portions (4a, 4b, 5a, 5b) having cavities (11 a, 11 b) that can be placed in removable extension by combination means (24a, 24b, 27, 32) and providing a passage (22) with one entrance (26), the pinching closing device (1) for cutting being in the open or closed state in which the sections (3a, 3b) are closed by locking means (25a, 25b) and in which the surfaces (13, 14) form a passage (23) for pinching and closing the tube; the pinching region of the tube is positioned in the cavity (11a) of one section (3a); the other section (3b) is positioned opposite the preceding section and the pinching closing device (1) for cutting is placed in the closed state, with the engagement of locking means (25a, 25b), the tube being positively pinched and closed in two positive pinching areas and maintained as such; the tube is cut between the portions (4a and 5a, 4b and 5b) in the closed state, using the cutting member (2), making said member pass through the passage (22), without interfering with the pinching closing device (1) for cutting, and the portions (4a and 4b, 5a and 5b) are separated.
