Patent Images
1. A pressure infusion device for infusing liquid by the application of pressure from a liquid-filled flexible bag into a patient, comprising:
- a laminated member including a central section and end sections on each side thereof, said central section being sealed along its top, bottom and sides thereby defining a bladder section, said laminated member normally assuming a substantially flat open position so that a liquid-filled flexible bag can be positioned along an inside surface of said bladder section;
fastening means on said inside surface of said bladder section for supporting and maintaining the liquid-filled flexible bag in position along said bladder section;
securing means on said end sections, said securing means extending substantially the entire length of said end sections for securing said end sections together in engagement so that said bladder section surrounds substantially all of the liquid-filled flexible bag and said laminated member completely encompasses the liquid-filled flexible bag; and
pumping and valve means connected to said bladder section for pumping fluid into said bladder section so that said bladder section applies pressure substantially throughout the liquid-filled flexible bag to infuse liquid therefrom into a patient.
