1. A fluid delivery system comprising:
- a fluid container;
at least two pressurizing chambers in fluid connection with the fluid container, each of the at least two pressurizing chambers having an input and an output, the input of each of the at least two pressurizing chambers in fluid connection with a connector, wherein the at least two pressurizing chambers are disposed generally parallel to each other to form separate flow paths, a common outlet in fluid connection with the output of each of the at least two pressurizing chambers;
an inlet valve in fluid connection with each of the at least two pressurizing chambers and operable to allow fluid to enter the at least two pressurizing chambers from the fluid container but to prevent fluid from flowing from the at least two pressurizing chambers into the fluid container;
an outlet valve in fluid connection with each of the at least two pressurizing chambers and operable to allow fluid to enter the common outlet from the output of each of the at least two pressurizing chambers but to prevent fluid from flowing from the common outlet into the at least two pressurizing chambers; and
a pumping mechanism permanently in fluid connection with the fluid container, the pumping mechanism comprising drive members cooperating with the at least two pressurizing chambers to pump fluid from the fluid container and to pressurize fluid within the at least two pressurizing chambers, wherein the drive members sequentially compress the pressurizing chambers to sequentially pass fluid through the separate flow paths and provide substantially continuous fluid flow to the common outlet.

Abstract
A fluid delivery system includes a fluid container, two or more pressurizing chambers in fluid connection with the fluid container, a drive mechanism in operative connection with the two or more pressurizing chambers to pump fluid from the fluid container and an outlet in fluid connection with the two or more pressurizing chambers. Each of the two or more pressurizing chambers is formed from a flexible, resilient material that is adapted to be compressed to pressurize fluid therewithin.

9. An injection system, comprising:
-
a fluid container comprising one or more outlet ports through which fluid can be delivered to a destination other than a pumping mechanism; the pumping mechanism in permanent fluid connection with the fluid container, the pumping mechanism comprising at least two generally parallel pressurizing chambers; and a drive mechanism in operative connection with each of the at least two pressurizing chambers configured to pump fluid from the fluid container, wherein the at least two pressurizing chambers are disposed parallel to each other, and wherein each of the at least two pressurizing chambers has an input in fluid connection with the fluid container and an output, and wherein each of the at least two pressurizing chambers forms a separate flow path through the pumping mechanism. - View Dependent Claims (10, 11, 12, 13, 14)
