Enteral feeding pump with flow adjustment

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.

A safety interlock system for an enteral feeding pump

A safety interlock system (11) for a flow control apparatus (12) is disclosed that permits operation when a magnet-less administration feeding set (14) is properly mounted to recess (29) formed along the housing (20) of the flow control apparatus (12). The administration feeding set (14) comprises flexible patient tubing having a support member (18) at one end and a mounting member (30) including a magnetically-susceptible metallic component (21) at the other end thereof. A sensing arrangement (33)is provided by the flow control apparatus (12) for sensing the proper engagement of the metallic component (21) to the recess (29) of the flow control apparatus (12). A control means (40) permits operation of the flow control apparatus (12) when the metallic member (21) is properly engaged to recess (29), while terminating operation when the metallic member (21) is improperly engaged to recess (29).

Carrier for enteral feeding device

A carrier for an enteral feeding device including a pump, enteral feeding containers and tubing. The carrier has a case for holding the enteral feeding pump, and a shoulder strap for carrying the case. The shoulder strap has one or more compartments for holding the one or more enteral feeding containers. The carrier permits a patient to receive nutrition from the enteral feeding device concealed within the carrier while the patient is mobile.

System and method to detect and respond to iced sensors in exhaust after-treatment system

A combustion system (100), a control module (104) for a combustion system (100) and a method of operating the combustion system (100) are disclosed. The method may be implemented by the control module (104) in the combustion system (100). The method comprises predicting an iced condition of the pressure sensor assembly (240); responsive to predicting the iced condition, controlling exhaust emissions without using a pressure parameter sensed with the pressure sensor assembly (240) in the iced condition; predicting a de-iced condition of the pressure sensor assembly (240); and responsive to predicting the de- iced condition, controlling the exhaust emissions using the pressure parameter sensed with the pressure sensor assembly (240) in the de-iced condition..

Fluid detection in an enteral feeding set

Detection of fluid conditions in an administration set. A light source is positioned to transmit an infrared light through administration set tubing and any fluid therein. A light sensor senses the infrared light transmitted through the tubing and generates an output signal. A frequency of the output signal is a function of an intensity of the light transmitted through the tubing. A processor receives and determines the frequency of the output signal, and compares the determined frequency to threshold frequency values to determine whether fluid is in the tubing. The processor also monitors the generated output signal to determine if the frequency of the output signal changes over time, and determines whether fluid is flowing in the tubing as a function of the determined change in frequency.
