System for dispensing fluid
Provided is a system for dispensing fluid. The system includes a housing defining a chamber; an inflatable bag disposed in the chamber and adapted to contain a fluid, the bag being in fluid communication with a flow path for flow of the fluid out of the bag; and a pressure source for inflating the bag to force the fluid from the bag to the flow path at a controlled rate. The bag inflates against an inner surface of the housing such that, prior to the bag being fully inflated, the fluid contained in the bag is forced from the bag at the controlled rate.
1. A system for dispensing fluid comprising:
a housing defining a chamber;
an inflatable bag disposed in the chamber and including an inner volume that contains a fluid, the inner volume of the bag being in fluid communication with a flow path for flow of the fluid out of the bag;
a pressure source in fluid communication with the inner volume of the bag via an inlet for inflating the bag to force the fluid from the bag to the flow path at a controlled rate;
wherein the bag inflates against an inner surface of the housing such that, prior to the bag being fully inflated, the fluid contained in the bag is forced from the bag at the controlled rate.
2. The system for dispensing fluid according to claim 1 , wherein the housing is formed of a solid, non-flexible material.
3. The system for dispensing fluid according to claim 1 , wherein a plurality of ribs are formed on the inner surface of the housing.
4. The system for dispensing fluid according to claim 3 , wherein the plurality of ribs are spaced apart along the inner surface of the housing with equal distance between adjacent ribs.
5. The system for dispensing fluid according to claim 1 , wherein one end of the housing is closed and the other end of the housing is open to receive the bag therein.
6. The system for dispensing fluid according to claim 1 , wherein one end of the housing includes a removable top that removably attaches to the housing.
7. The system for dispensing fluid according to claim 1 , wherein the housing includes a pair of side portions configured to be expandable to provide an adjustable length of the housing.
8. The system for dispensing fluid according to claim 1 , wherein one end of the housing includes a port through which an inlet tube of the bag extends.
9. The system for dispensing fluid according to claim 1 , wherein one end of the housing includes a port through which an outlet valve of the bag extends.
10. The system for dispensing fluid according to claim 1 , wherein a first end of the housing includes a first port through which an inlet tube of the bag extends, and a second end of the housing includes a second port through which an outlet valve of the bag extends.
