Abstract

A feeding set for use with a peristaltic enteral feeding pump to deliver nutritional liquid fluid to a patient includes a container having nutritional liquid. A conduit assembly includes tubing placeable in fluid communication with the container and adapted for mounting on the enteral feeding pump. The tubing provides a fluid pathway for delivering the nutritional liquid from the container to a patient when the tubing is mounted on the enteral feeding pump. An identification member is mounted on the conduit assembly and has at least one characteristic of a nutritional liquid associated with the feeding set represented by the identification member. The identification member is positioned on the conduit assembly so as to permit automatic identification by the enteral feeding pump of the at least one characteristic of the nutritional liquid upon mounting the conduit assembly on the enteral feeding pump.

Claims

1. A feeding set for use with a feeding pump to deliver nutritional liquid to a patient, the feeding set comprising:

a container to store the nutritional liquid;

tubing in fluid communication with the container and being adapted for mounting on the feeding pump, the tubing providing a fluid pathway for delivering the nutritional liquid from the container to the patient; and

an identification member representative of the nutritional liquid in the container, the identification member configured to permit identification by the feeding pump of at least one characteristic of the nutritional liquid upon mounting of the identification member on the feeding pump, the at least one characteristic of the nutritional liquid comprising at least one of a nutritional content, a fluid flow property, and a brand or brand name of the nutritional liquid.

2. The feeding set of claim 1, further comprising a cassette connected to the tubing.

3. The feeding set of claim 2, wherein the identification member is mounted on the cassette.

4. The feeding set of claim 1, wherein the identification member comprises at least one magnet arranged to represent the nutritional liquid in the container.

5. The feeding set of claim 4, wherein the identification of the at least one characteristic is based on a number and relative positions of the at least one magnet.

6. The feeding set of claim 1, wherein the fluid flow property comprises a viscosity of the nutritional liquid.

7. The feeding set of claim 1, wherein the nutritional content comprises a caloric content of the nutritional liquid.

8. The feeding set of claim 1, wherein a family of the nutritional liquids associated with the feeding set is represented by the identification member.

9. A method of detecting a characteristic of a nutritional liquid associated with a feeding set connected to a feeding pump, the method comprising:

mounting a feeding set on a housing of the pump, the pump configured to act on the feeding set to produce flow of a nutritional liquid from a container through the feeding set during operation of the pump;

detecting engagement of the feeding set with the housing of the pump, the feeding set including at least one identification component representative of the nutritional liquid in the container;

reading the at least one identification component to identify at least one characteristic of the nutritional liquid associated with the feeding set, the at least one characteristic of the nutritional liquid comprising at least one of a nutritional content, a fluid flow property, and a brand or brand name of the nutritional liquid; and

identifying, with a processor connected to a reader of the pump, the at least one characteristic of the nutritional liquid upon detecting the engagement of the feeding set with the housing of the pump.

10. The method of claim 9, wherein the processor identifies the at least one characteristic based on a number and relative positions of the at least one identification component.

11. The method of claim 9, wherein the at least one identification component comprises at least one magnet arranged to represent the nutritional liquid in the container.

12. The method of claim 9, wherein the nutritional content comprises a free water content of the nutritional liquid.

13. The method of claim 9, wherein the processor controls flow of the nutritional liquid through the feeding set based on the identified at least one characteristic.

14. The method of claim 9, wherein the pump is linked to a communications network.

15. The method of claim 9, further comprising wirelessly communicating at least one of a frequency of delivery of the nutritional liquid, an amount of the nutritional liquid delivered, and a type of the nutritional liquid delivered.

16. The method of claim 9, wherein the pump automatically determines a flow rate for delivering the nutritional liquid through the feeding set based on the at least one characteristic of the nutritional liquid identified by the reader upon the engagement of the feeding set with the housing.

17. The method of claim 9, wherein the pump automatically initiates a compliance operation including monitoring of a volume of the nutritional liquid and a number of calories delivered to a patient through the feeding set upon engagement of the feeding set with the housing.

18. A feeding set for use with a feeding pump to deliver nutritional liquid to a patient, the feeding set comprising:

a container configured to store the nutritional liquid;

tubing in fluid communication with the container and being adapted for mounting on the feeding pump, the tubing providing a fluid pathway for delivering the nutritional liquid from the container to the patient;

a cassette connected to the tubing; and

an identification member mounted on the cassette, the identification member representative of at least one of a nutritional content, a fluid flow property, and a brand or brand name of the nutritional liquid in the container.

19. The feeding set of claim 18, wherein the identification member includes at least one magnet, and the identification of the type of the nutritional liquid is based on a number and relative positions of the at least one magnet.
