Enteral feeding pump system
Methods and apparatus for an enteral feeding pump system. A method of directing flow for a coil includes drawing fluid from a source and delivering fluid, the coil including input and output check valves to prevent a back flow of fluid.
1. A method for flowing fluid comprising:
providing a fluid delivery set having a source end and a patient end with a repeatable compression portion intermediate the ends, the fluid delivery set comprising a disposable tubing set made of low-grade PVC tubing throughout its length;
providing an enteral feeding pump for regulating the flow of fluid into and out of the fluid delivery set;
compressing said repeatable compression portion made of low-grade PVC tubing of said fluid delivery set using the enteral feeding pump;
selectively closing a first means for regulating the flow of medical fluid out of the compression portion; and
selectively opening a second means upstream of the repeatable compression portion for regulating the flow of medical fluid into the compression portion from the source end, the first means and the second means comprising check valves positioned at opposite ends of the disposable tubing set.
2. A disposable fluid delivery set assembly comprises:
a source end;
a compression portion; and
a patient end connector with an integral check valve, the integral check valve having a cracking pressure that is higher than a maximum elevation difference between a source container and a patient, preventing excess flow and enabling unidirectional pumping when a proximal tubing section relative to the compression portion is captured in a pinch valve.
3. A method for flowing fluid unidirectionally using an enteral pumping system including a disposable fluid delivery set and enteral feeding pump for delivery medical fluids comprises:
providing a fluid delivery set which includes a source end, a patient end, and the repeatable compression portion;
providing the enteral feeding pump is for repeatable compressing of the compression portion and regulating the flow of fluid into and out of the compression portion;
inserting the fluid delivery set into the enteral feeding pump;
compressing the repeatable compression portion of the fluid delivery set using the enteral feeding pump;
closing the flow of medical fluid out of the compression portion with a regulating means and into the patient end using the enteral feeding pump;
opening the regulating means opens to cause the flow of medical fluid into the compression portion from the source end using the enteral feeding pump;
releasing the compressed portion using the enteral feeding pump to allow medical fluids to be drawn into the fluid delivery set through the regulating means and into the compression portion from the source end;
closing the regulating means to close the flow of medical fluid into the compression portion from the source end using the enteral feeding pump; and
compressing the compressing portion by the enteral feeding pump to move medical fluids out of the compression portion, through the regulating means, and into the patient end.
4. The method of claim 3 wherein the regulating means is a check valve.
