Abstract

There is provided a venting system for enteral feeding having a reflux bag in fluid communication with an enteral feeding site on a patient. The bag has a vent that relieves enteral pressure from the patient and is located within a bellows that compresses the reflux bag after the vent relieves. The system does not rely on gravity to urge the liquid in the reflux bag back to the patient so it may be used by sleeping patients who change positions. It may also be placed in a backpack so that the patient may be freed from having to remain seated or prone for long periods of time and can instead lead a more normal lifestyle.

Claims

1. A venting system for enteral feeding comprising an enteral feeding gastrostomy site that allows nutritional solutions or medicines directly into a stomach or intestines of a patient through a stoma through a wall of said stomach or intestines, a bag in fluid communication with said site, said bag receiving enteral digestive gas from said patient, said bag having a vent and being located within a bellows that compresses said bag after said vent allows said enteral digestive gas from said patient to escape the venting system.

2. The venting system of claim 1 wherein said vent relieves at a pressure of between 1.4 and 5.5 kPa.

3. The venting system of claim 1 wherein said vent relieves at a pressure of about 3.48 kPa.

4. The venting system of claim 1 wherein said vent comprises a slit or hole in said bag and said slit or hole is covered with a nonwoven fabric that is a microporous membrane material.

5. A venting system for enteral feeding comprising a bag in fluid communication with an enteral feeding gastrostomy site on a patient, said bag having a vent, said bag located within a means for compressing said bag after said vent allows said digestive gas to escape the venting system, without human interaction.

6. The venting system of claim 5 wherein said vent relieves at a pressure of between 1.4 and 5.5 kPa.

7. The venting system of claim 5 wherein said vent relieves at a pressure of about 3.48 kPa.

8. The venting system of claim 5 that system relieves gas pressure regardless of patient positioning or orientation.
