Abstract

A medical fluid container is disclosed that comprises a single reservoir of fluid impermeable material having a fluid impermeable barrier dividing the reservoir into at least first and second fluid-holding compartments. A valve is selectively movable to allow flow of fluid from the compartments. A method of dispensing medical fluids from a medical fluid container is also disclosed.

Claims

1. A medical fluid container adapted for connection to a fluid delivery tube, said container comprising:

a single reservoir of fluid impermeable material, the reservoir having a fluid impermeable barrier dividing the reservoir into at least first and second separate fluid-holding compartments;

a first fluid flow path from the first compartment of the reservoir to said fluid delivery tube;

a second fluid flow path from the second compartment of the reservoir to the fluid delivery tube; and

a valve selectively movable from a first position allowing flow of a fluid along said first flow path from the first compartment but blocking flow of fluid from the second compartment along said second flow path, to a second position allowing flow of a fluid along said second flow path from the second compartment but blocking flow of fluid from the first compartment along said first flow path, to a third position blocking flow of fluid from the first and second compartments.

2. A medical fluid container as recited in claim 1 wherein the valve is adapted for repeated selected movement between the first and second positions.

4. A medical fluid container as recited in claim 2 wherein the valve comprises a valve housing and a valve member movable in the valve housing, said first flow path comprising a first flow passage in the valve member, and said second flow path comprising a second flow passage in the valve member separate from the first flow passage.

5. A medical fluid container as recited in claim 4 wherein said valve member is a spool mounted for sliding movement in a cavity in the valve housing, said spool having a first end portion, a second end portion, and an intermediate portion between the end portions, and wherein said first flow passage is located between the first end portion and the intermediate portion of the spool, and the second flow passage is located between the second end portion and the intermediate portion of the spool.

6. A medical fluid container as recited in claim 1 wherein said first flow path comprises a first outlet in the reservoir on a first side of the barrier corresponding to the first compartment and the second flow path comprises a second outlet in the reservoir on a second side of the barrier corresponding to the second compartment.

7. A medical fluid container as recited in claim 6 wherein a flow area of the first outlet is larger than a flow area of the second outlet.

8. A medical fluid container as recited in claim 4 further comprising a connector on said valve housing for connecting a fluid delivery line to the valve housing, said connector having a releasable connection with the valve housing.

9. A medical fluid container as recited in claim 7 in combination with the delivery tube.

10. A medical fluid container as recited in claim 1 wherein the reservoir and the fluid impermeable barrier are substantially rigid and self-supporting.

11. A medical fluid container as recited in claim 8 wherein the fluid impermeable barrier comprises a partition having fluid tight seals with inside surfaces of the reservoir to define the first compartment on one side of the partition and the second compartment on an opposite side of the partition.

12. A medical fluid container as recited in claim 1 further comprising a first inlet for the first compartment and a second inlet for the second compartment such that fluid may be introduced into the first and second compartments independently.

13. A medical fluid container as recited in claim 1 wherein the container has at least one indicator for designating that one of the compartments is for holding a particular type of medical fluid.

14. A medical fluid container as recited in claim 13 wherein the container is for enteral feeding, the first compartment being adapted for holding liquid food, and the second compartment being adapted for holding rinse fluid, and wherein a first indicator designates that the first compartment is for holding liquid food, and a second indicator designates that the second compartment is for holding rinse fluid.

15. A medical fluid container as recited in claim 14 further comprising measurement indicators on at least one of the first and second compartments for indicating the volume of fluid in the compartment.

16. A medical fluid container as recited in claim 1 further comprising a support connected to the container and adapted for supporting the container in a generally vertical orientation.

17. A medical fluid container as recited in claim 1 wherein components of the container associated with one of the first and second compartments are color coded according to a color assigned to a medical fluid designated to be held within respective compartments.
