Abstract
Abstract Sterile water in a drum communicates through a tube with a flexible container body in which a dry water soluble intravenous feeding material has been placed, the interior of an initially deflated flexible bag in the drum being subjected to air pressure to force sterile water in the drum and externally of the flexible bag through the tube into the flexible container body to contact the water soluble material and form an intravenous feeding solution in the container body.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
The method of preparing intravenous feeding containers comprising: placing in a flexible container body a quantity of dry water soluble intravenous feeding material, said container body having an outlet provided with a stopper, providing a drum containing sterile water, with one end portion of a tube extending into said water, a hollow needle secured to the other end portion of the tube and extending through said stopper, and subjecting the interior of said drum to air pressure to force said water through the tube and needle into said container body to contact said water soluble material and form an intravenous feeding solution.
Claim 2
Independent Claim
102 words
The method of preparing intravenous feeding containers comprising: placing in a flexible container body a quantity of dry water soluble intravenous feeding material, said container body having an outlet provided with a stopper, providing a drum containing sterile water, with one end portion of a tube extending into said water, a hollow needle secured to the other end portion of the tube and extending through said stopper, and subjecting the interior of said drum to air pressure to force said water through the tube and needle into said container body to contact said water soluble material and form an intravenous feeding solution.
Claim 3
Independent Claim
102 words
The method of preparing intravenous feeding containers comprising: placing in a flexible container body a quantity of dry water soluble intravenous feeding material, said container body having an outlet provided with a stopper, providing a drum containing sterile water, with one end portion of a tube extending into said water, a hollow needle secured to the other end portion of the tube and extending through said stopper, and subjecting the interior of said drum to air pressure to force said water through the tube and needle into said container body to contact said water soluble material and form an intravenous feeding solution.
Claim 4
Independent Claim
102 words
The method of preparing intravenous feeding containers comprising: placing in a flexible container body a quantity of dry water soluble intravenous feeding material, said container body having an outlet provided with a stopper, providing a drum containing sterile water, with one end portion of a tube extending into said water, a hollow needle secured to the other end portion of the tube and extending through said stopper, and subjecting the interior of said drum to air pressure to force said water through the tube and needle into said container body to contact said water soluble material and form an intravenous feeding solution.
Claim 5
Dependent Claim
39 words
The method as defined in claim 1; said drum having an initially deflated flexible bag therein, said air pressure being supplied to the interior of said bag to inflate the same and thereby force the water from said drum.
Claim 6
Dependent Claim
33 words
The method as defined in claim 1; said tube extending to the lower end of the drum to enable said air pressure to force substantially all of the sterile water from the drum.
