Abstract

In some embodiments, apparatuses and methods are provided herein useful to provide fluid nutrition and hydration. In one illustrative example, a feeding set for use with a peristaltic enteral feeding pump has sections of flexible tubing or conduit, a dispensing control valve that is in fluid communication with the tubing, and a retention disk. In some configurations, the feeding set has as attachment mechanism, which may be formed by one clips or hooks extending from the dispensing control valve and coupling geometry of the retention disk. By some approaches, the clips or hooks and the coupling geometry are configured to attach the feeding set with the pump, such as by attaching the feeding set to an internal panel of the feeding pump. In operation, the feeding set and pump are used to move fluid nutrition and hydration from a container or bag to the patient in a controlled manner.

First claim

What is claimed is:

1. A feeding set comprising:
a dispensing control valve sized for placement at least partially within an enteral feeding pump and configured to releasably engage a first retention portion of the enteral feeding pump, the dispensing control valve having a plunger positioned at least partly therein to selectively control a flow of fluid through the dispensing control valve;
a peristaltic tubing element fluidly connected to an exit of the dispensing control valve, the peristaltic tubing element being elastomeric; and
an attachment mechanism configured to releasably engage a second retention portion of the enteral feeding pump;
wherein the peristaltic tubing element is sized to be placed under tension and for said peristaltic tubing element to be retained with respect to the enteral feeding pump via tension when the dispensing control valve engages the first retention portion of the enteral feeding pump and the attachment mechanism engages the second retention portion of the enteral feeding pump.

2. The feeding set of claim 1 , wherein the attachment mechanism comprises a retention disk and the peristaltic tubing element pulls the retention disk upward toward the dispensing control valve in an assembled, installed configuration.

3. The feeding set of claim 2 , further comprising:
a second tubing element for fluidly connecting the dispensing control valve with at least one bag of fluid; and
a third tubing element configured to be fluidly connected to the peristaltic tubing element, via the retention disk, wherein the third tubing element has a patient coupling fitted thereto.

4. The feeding set of claim 3 , wherein the patient coupling comprises a male enfit.

5. The feeding set of claim 1 , wherein the dispensing control valve has a clip and the first retention portion of the enteral feeding pump includes a panel or a portion thereof and wherein the clip of the dispensing control valve is configured to engage the panel in an assembled, installed configuration.

6. The feeding set of claim 1 , wherein the plunger of the dispensing control valve includes a plurality of gaskets.

7. A feeding set with an attachment mechanism for use with an enteral feeding pump, the feeding set comprising:
a dispensing control valve having a plunger positioned at least partly therein and at least one clip extending therefrom, the at least one clip configured to engage with a first portion of an internal panel of an enteral feeding pump and the plunger configured to selectively control a flow of fluid through the dispensing control valve;
a peristaltic, first tubing element fluidly connected to an exit of the dispensing control valve, the peristaltic, first tubing element being elastomeric;
a retention disk configured to engage a second portion of the internal panel and the peristaltic, first tubing element pulling the retention disk upward, through tension, toward the dispensing control valve and into engagement with the second portion of the internal panel, such that the feeding set retains its connection with the internal panel of the enteral feeding pump via the at least one clip and the retention disk;
a second tubing element for fluidly connecting at least one bag of fluid to the dispensing control valve; and
a third tubing element configured to be fluidly connected to the peristaltic, first tubing element and the third tubing element having a patient coupling fitted thereto.

8. The feeding set of claim 7 wherein the dispensing control valve has one of feed and flush ports, a feed port, or a flush port.

9. The feeding set of claim 7 wherein the dispensing control valve has a feed port and a flush port and the at least one clip of the dispensing control valve includes a first attachment clip associated with the feed port and a second attachment clip associated with the flush port.

10. The feeding set of claim 7 wherein the at least one clip has a hook configuration that extends from an upper surface of the dispensing control valve.

11. The feeding set of claim 7 wherein the has a plurality of gaskets.

12. The feeding set of claim 11 wherein the plunger further comprises multiple narrow portions that have at least portions with a smaller diameter as compared to plunger portions having a gasket associated therewith, wherein the portions with the smaller diameter permit fluid to move therealong.

13. The feeding set of claim 12 wherein the dispensing control valve includes a feed port and a flush port, and the plurality of gaskets of the plunger includes three gaskets, and the plunger is reciprocal between a feed configuration, a flush configuration, or a no-flow configuration based the position of the three gaskets, wherein the plunger and the three gaskets are moved via a grip that is configured to mate with a knob on a reciprocating arm that is rotatably attached to the internal panel.

14. The feeding set of claim 13 wherein the first portion of the internal panel comprises a first edge and the second portion of the internal panel comprises a second edge and wherein the internal panel further comprises a pie-shaped depression configured to house the reciprocating arm with the knob associated therewith.

15. The feeding set of claim 14 wherein the internal panel further comprises an arcuate depression partially extending from the first edge to the second edge configured to seat at least a portion of the peristaltic, first tubing element and the dispensing control valve therein and the first edge and the second edge are disposed on opposite edges of the internal panel.

16. The feeding set of claim 7 wherein the retention disk comprises a tapered section to connect to the peristaltic, first tubing element, a flange, and a collar.

17. The feeding set of claim 16 wherein the flange comprises an outer ring disposed on a first side facing the tapered section, wherein the outer ring defines a flange depression between the tapered section and the outer ring.

18. The feeding set of claim 17 wherein the internal panel has at least one of an extension or a depression configured to mate with the outer ring or the flange depression to mate the retention disk with the internal panel via the upward force on the retention disk resulting from the elastomeric material of the peristaltic, first tubing element.

19. The feeding set of claim 17 wherein the outer ring has an angled surface that facilitates engagement of a first side of the flange of the retention disk with a lower edge of the internal panel.

20. The feeding set of claim 17 wherein the third tubing element is fluidly connected to the peristaltic, first tubing element via the retention disk, where the tapered section of the retention disk extends into the peristaltic, first tubing element and an end of the third tubing element is disposed within the collar of the retention disk.

21. The feeding set of claim 7 further comprising at least one spike cap configured to protect at least one end of the second tubing element.

22. The feeding set of claim 7 wherein the enteral feeding pump further comprises a pump door hingedly attached to a housing body, wherein the pump door moves from a first position to a second position, wherein the first position closes the pump door and further secures the internal panel, the peristaltic, first tubing element, and the dispensing control valve of the feeding set relative to a remainder of the enteral feeding pump and the internal panel has a rectangular opening therein through which a plurality of
