FILM WELDED RESERVOIR BAG FOR BREATHING CIRCUIT AND METHOD OF MAKING THE SAME
Document Type and Number:
WIPO Patent Application WO2001083012
Kind Code:
B1
Abstract:
A pulmonary sized bag (100) formed of a non-latex material, including a bag body (102) formed of panels of resin film material (202, 204) welded to one another along a weld line (206) defining a seam (104) of the bag body bounding an interior volume (112), and an exterior seam portion at an exterior surface (120) of the bag. One of the interior seam portion and exterior seam portion comprises free edges of the seam (216,218) and the other one of such seam portions is devoid of free edges. The bag is formable by various techniques, including radio frequency welding, impulse heating, solvent bonding, etc., and is usefully employed in a breathing circuit to obviate the necessity of using latex breathing bags.
