Abstract: A pack (10) for carrying an IV bag (12) and an ambulatory IV pump (16). The pack includes an inner back (30) and an outer back (32) that are sewn together on three edges to form a pocket (38) in which a plastic plate (40) is inserted to provided rigidity. A pair of inner flaps (64, 66) secure the IV bag against the back of the pack. Several straps (42, 50, 52, 62) also secure the IV bag in place, limiting its lateral and longitudinal movement relative to the back of the pack. Outer flaps (70, 72) overlap to enclose the IV bag. One of the outer flaps includes a pocket (14) in which the IV pump (16) is carried. The flaps and straps are secured by engaging a hook material attached to one surface of the strap or flap to a loop material attached to another surface.
