Abstract
A priming system including a resilient chamber having flexible walls and a first check valve in a first fluid pathway between the resilient chamber and a fluid reservoir such that a fluid flows through the first check valve only in a direction from the fluid reservoir toward the resilient chamber and the fluid returns to the fluid reservoir through a second fluid pathway between the resilient chamber and the fluid reservoir upon compression of the walls of the resilient chamber.
Claims9
A priming system for delivering a fluid comprising:
- a resilient chamber having flexible walls;
- a housing comprising an inlet passage between a fluid reservoir and the resilient chamber, and an outlet passage separate from the inlet passage and between the fluid reservoir and the resilient chamber;
- a manifold removably attached to the housing, the manifold including an inlet port, an outlet port and the resilient chamber,
- wherein the inlet port is fluidly coupled to the inlet passage of the housing, the outlet port is fluidly coupled to the outlet passage of the housing, and the resilient chamber is fluidly coupled to the housing via the manifold;
- and
- a first check valve, in a flow path between the inlet port and the resilient chamber, configured to resist a fluid flow through the first check valve from the resilient chamber toward the inlet port;
- wherein the fluid returns to the fluid reservoir through the outlet port and the outlet passage upon compression of the walls of the resilient chamber.
