  • Publication number: 20240000668
    Abstract: The present specification is directed to systems, devices, and methods of portable enteral pump systems for feeding and/or flushing an ambulatory patient. Embodiments provide an enteral pumping device that may be loaded by a patient from a front and a top side of the pumping device and is therefore more convenient to use. Further, embodiments incorporate a single rotor pump for dual-use purposes of feeding nutrients and flushing fluids to the patient. A pinch valve is placed between the parallel sides of the two tubes to cut off fluid flow when required. At least one sensor is also placed between the rotor pump and an outlet. The sensors are used to detect occlusions and the type of disposables used, among other purposes.
