Claims
- 1. A method of manufacturing a medical bag formed by joining a medical bag, defined by thermoplastic resin sheets, with a tubular port wherein both said sheets and said port are made of a thermoplastic resin not capable of being molten by application of high frequency-wave energy, comprising the steps of:
- inserting a core mold for high frequency welding within the tubular port;
- inserting said tubular port between the sheets defining an opening into said bag;
- placing exothermic objects, which generate heat when applied with high frequency-wave energy selected from the group consisting of cardboard and cotton cloth, on the outer sides of said sheets;
- fitting the tubular port, the sheets and the exothermic objects between electrodes adapted to accommodate the shape of the tubular port, and for high frequency welding;
- welding sheets to the outside of the tubular port by applying high frequency-wave energy to the mold; and
- removing the exothermic objects from the medical bag after high frequency-wave energy is applied.
