Enteral feeding pump with flow adjustment
First Claim
1. An enteral fluid delivery system, comprising:
- a pump having a motor coupled to a rotor, the rotor configured to accept a portion of tubing, the motor configured to drive the rotor to compress the tubing for delivering an enteral feeding fluid to a patient during a feeding cycle;
a memory storing at least one characteristic representative of a plurality of types of enteral feeding fluids;
a user interface operatively connected to the memory, the user interface enabling a user to select at least one of the types of enteral feeding fluids; and
a processor operatively connected to the pump, the processor being configured to provide a flow rate of the pump to deliver the selected enteral feeding fluid based on the at least one characteristic of the selected enteral feeding fluid, wherein the processor is further configured to retrieve predetermined flow correlation data from the memory and to adjust the flow rate by altering a rotational speed of the motor based on the retrieved predetermined flow correlation data stored in the memory, the predetermined flow correlation data stored in the memory corresponding to a viscosity of the selected enteral feeding fluid, and the predetermined flow correlation data comprising a ratio of a user-defined feeding rate to an average feeding rate of the selected enteral feeding fluid relative to the viscosity thereof.

Abstract
An enteral fluid delivery system includes a pump having a motor coupled to a rotor configured to accept a portion of a tubing of a feeding set. The motor drives the rotor, which compresses the tubing to deliver to a patient enteral fluid during a feeding cycle. The system includes a user interface that is operatively connected to a memory that stores a plurality of types of enteral fluids. The user interface enables a user to select at least one type of enteral fluid. The system also includes a processor that is operatively connected to the pump. The processor adjusts the flow rate of the pump to deliver the selected enteral fluid for delivery based on one or more characteristics of the feeding fluid such as the viscosity or the caloric content.
