Fluid delivery system and method
First Claim
1. A liquid delivery system comprising:
- a container having a filling inlet in the upper portion thereof and an outlet in the lower portion thereof, said filling inlet adapted to receive a given amount of liquid poured into the interior of said container, said liquid outlet having a control valve means in fluid communication therewith to control flow from said container outlet;
a first hanger member on said container for hanging said container in a first hanging position, said container outlet when in said first hanging position being in gravity flow communication with the entire given amount of liquid in said container so that when said control valve means is opened, the entire given amount of fluid in said container will flow out of the container;
a second hanger member on said container for hanging said container in a second hanging position, said container outlet when in said second hanging position being in gravity flow communication with a portion of the entire given amount of fluid in said container so that when said control valve means is opened, only said portion of the entire given amount of fluid in said container will flow out of the container;
said interior of said container when in said second hanging position is divided into two separate chambers wherein a portion of said given amount of liquid will be contained in one of said chambers and a portion of said given amount of liquid will be contained in the other of said chambers, said two chambers when in said second hanging position having no gravity flow communication therebetween; and
said two separate chambers when in said second hanging position are separated by a barrier means which extends from one edge of said container to a point spaced from the opposite edge of said container.

Abstract
A fluid delivery system including a flexible plastic container having a filling inlet in the upper portion thereof and a feeding outlet in the lower portion thereof with a control valve to control flow from the outlet. The container is provided with a first hanger member for hanging the container on a first hanging axis. The container is further provided with a second hanger member for hanging the container on a second hanging axis which extends at right angles to the first hanging axis. The container is provided with an internal barrier means which extends from one edge of the container to a point spaced from the opposite edge of the container along a line parallel to the second hanging axis.

5. A liquid delivery system comprising:
-
a flexible plastic container having a filling inlet in the upper portion thereof and an outlet in the lower portion thereof, said filling inlet adapted to receive a given amount of liquid poured into the container, said liquid outlet having a control valve means in fluid communication therewith to control flow from said container outlet; a first hanger member on said container for hanging said container in a first hanging position, said first hanger member located on a first hanging axis; a second hanger member on said container for hanging said container in a second hanging position, said second hanger member located on a second hanging axis which extends at right angles to said first hanging axis; an internal barrier means in said container extending from one edge of said container to a point spaced from the opposite edge of said container, said barrier means extending in a line parallel to said second hanging axis; and said first and second hanger members and said barrier means cooperating so that when said container is in its first hanging position said container outlet will be in gravity flow communication with the entire given amount of liquid in said container so that when said control valve means is opened the entire given amount of fluid in said container will flow out of the container, said first and second hanger members and said barrier means further cooperating so that when said container is in its second hanging position, said container will be in gravity flow communication with only a portion of the entire given amount of fluid in said container so that when said control valve means is opened only said portion of the entire given amount of fluid in said container will flow out of the container. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A liquid delivery system comprising:
-
a flexible plastic container having a filling inlet in the upper portion thereof and an outlet in the lower portion thereof, said filling inlet adapted to receive a given amount of liquid poured into the container, said liquid outlet having a control valve means in fluid communication therewith to control flow from said container outlet; a first hanger member on the upper portion of said container for hanging said container in a first hanging position, said container outlet when in said first hanging position being in gravity flow communication with the entire given amount of liquid in said container so that when said control valve means is opened, the entire given amount of fluid in said container will flow out of the container; and a second hanger member on said container located intermediate the top and bottom of the container for hanging said container in a second hanging position, said container when in said second hanging position being folded along a horizontal line to form two separate chambers, said second hanger member being attached to said container at the fold between the said two separate chambers, said container outlet when in said second hanging position being in gravity flow communication with a portion of the entire given amount of fluid in said container so that when said control valve means is opened only said portion of said given amount of fluid in said container will flow out of the container. - View Dependent Claims (15, 16)

17. A method of enteral feeding comprising the steps of:
-
(a) filling a flexible plastic container with a given amount of liquid diet with the container in a first hanging position; (b) repositioning the container to a second hanging position wherein the liquid diet will flow into two separate chambers in said container, said two separate chambers when in said second hanging position having no gravity flow communication therebetween; (c) feeding the diet from only one of the chambers to a patient. - View Dependent Claims (18, 19)

20. A liquid delivery system comprising:
-
a container having a filling inlet in the upper portion thereof and an outlet in the lower portion thereof, said filling inlet adapted to receive a given amount of liquid poured into the interior of said container, said liquid outlet having a control valve means in fluid communication therewith to control flow from said container outlet; a first hanger member on said container for hanging said container in a first hanging position, said container outlet when in said first hanging position being in gravity flow communication with the entire given amount of liquid in said container so that when said control valve means is opened, the entire given amount of fluid in said container will flow out of the container; and a second hanger member on said container for hanging said container in a second hanging position, said container outlet when in said second hanging position being in gravity flow communication with a portion of the entire given amount of fluid in said container so that when said control valve means is opened, only said portion of the entire given amount of fluid in said container will flow out of the container; said interior of said container when in said second hanging position is divided into two separate chambers wherein a portion of said given amount of liquid will be contained in one of said chambers and a portion of said given amount of liquid will be contained in the other of said chambers, said two chambers when in said second hanging position being separated by a barrier means, said barrier means positioned between said two separate chambers and serving to prevent gravity flow of liquid between said two separate chambers when said container is in said second hanging position. - View Dependent Claims (21, 22, 23, 24)
