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. An enteral feeding pump for use with a feeding set to deliver a nutritional liquid through the feeding set, the enteral feeding pump comprising:

a housing capable of receiving at least a portion of the feeding set;

a pumping device mounted in the housing and configured to act on the feeding set to produce fluid flow in the feeding set when the feeding set is received by the housing;

a processor operatively connected to the pumping device; and

a reader operatively connected to the processor and configured to read the feeding set to identify at least one characteristic of the nutritional liquid associated with the feeding set upon engagement of the feeding set with the housing, the at least one characteristic comprising at least one of a viscosity and a caloric content of the nutritional liquid associated with the feeding set.

2. The enteral feeding pump as set forth in claim 1 further comprising memory operatively connected to the processor, wherein the processor is configured to select and display a library subset from a library of nutritional liquids stored in the memory of the pump, the library subset being associated with the feeding set engaged with the housing.

3. The enteral feeding pump as set forth in claim 1 wherein the processor is configured to automatically determine a flow rate for delivering fluid through the feeding set based on the identified at least one characteristic of the nutritional liquid associated with the feeding set upon engagement of the feeding set with the housing.

4. The enteral feeding pump as set forth in claim 3 wherein the processor is programmed to automatically initiate a compliance operation whereby the pump monitors a volume of fluid and a number of calories delivered to the patient through the feeding set upon engagement of the feeding set with the housing.

5. A method of providing an enteral feeding pump for use with a nutritional liquid feeding set configured to deliver a nutritional liquid from a container through the feeding set, the method comprising:

mounting a pumping device on a housing of the pump, the pumping device configured to act on the feeding set to produce fluid flow in the feeding set during operation thereof;

disposing a reader on the housing, the reader configured to read the feeding set to identify at least one characteristic of the nutritional liquid associated with the feeding set; and

operatively connecting a processor to the reader, wherein the processor is configured to identify the at least one characteristic upon operational engagement of the feeding set with the housing, the at least one characteristic comprising at least one of a viscosity and a caloric content of the nutritional liquid associated with the feeding set.

6. The method as set forth in claim 5, further comprising providing the feeding set, wherein the feeding set comprises an identification member and tubing in fluid communication with the container, wherein the identification member is associated with the nutritional liquid in the container.

7. The method as set forth in claim 5 wherein a family of nutritional liquids associated with the feeding set is represented by the identification member.

8. The method as set forth in claim 5, further comprising operably connecting a memory to the processor, the memory configurable to include the at least one characteristic of the nutritional liquid to be associated with the feeding set.

9. The method as set forth in claim 5, further comprising providing instructions on non-transitory memory that are executable by the processor, the instructions comprising:

identifying the at least one characteristic of the nutritional liquid associated with the feeding set based on a representation from an identification member on the feeding set; and

operating the pump at a flow rate to achieve a target feeding rate based on the at least one characteristic.
