<p>PROBLEM TO BE SOLVED: To produce a bag for medical treatment in completely aseptic and dust-free state. SOLUTION: In this bag for medical treatment, the constitutive material of bag for medical treatment is extruded in the form of tube while being fused, a port part 13 having a bottom part heated to high temperature is welded on the side face of tube 4, the side face of this tube 4 is vertically pressed by a molding device and formed so as to position a fusing part in the vertical direction of the port part 13 while remaining a passage at the central part of tube 4 in width direction, and when forming this fusing part, the main body of bag for storing medicinal liquid is formed in the longitudinal direction of tube 4, the fusing part is cut after this passage is fused or simultaneously when the passage is fused, the port part 13 is mounted at the center of lower end part at the main body of bag for storing medicinal liquid, and fusing parts are formed on both the sides of main body of bag. This fusing part is in the form of slope inclined from near the lateral center of main body of bag to the upper and lower end parts of main body of bag while being turned closer to the longitudinal center.</p> |
