Abstract
Abstract A flexible, flat-collapsible bag containing parenteral solution may be adapted for aseptically receiving and mixing the contents of another container, with the flat-collapsible bag preferably initially containing, prior to receiving said contents, a liquid for parenteral administration in a volume of 30 to 70 percent of the holding capacity of said flat-collapsible bag. The bag defines at least a pair of access ports, one of the ports being sealingly connected to flexible, crimpable, thermoplastic tubing of a length of at least 11/2 inches, and a sealed connector member carried on the outer end of the flexible thermoplastic tubing, in which the seal connector member defines a sleeve including a sealing diaphragm in the bore thereof, with the sleeve constituting an extension of the flexible thermoplastic tubing. Accordingly, a piercing spike may sealingly enter the sleeve to rupture the diaphragm.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A flexible, collapsible container, carrying therewith a volume of solution comprising from 30 to 70 percent of the holding capacity of said collapsible container, said solution being selected from the group consisting of a carbohydrate parenteral solution and an amino acid nutrient parenteral solution, said container defining at least a pair of access ports, one of the ports being sealingly connected to a flexible, crimpable, thermoplastic tubing length of at least 11/2 inches, and a sealed connector member carried on the outer end of said flexible thermoplastic tubing, said sealed connector member defining a sleeve including a sealing diaphragm in the bore thereof, said sleeve constituting an extension of said flexible thermoplastic tubing, and a second container which includes the other type of said parenteral solutions in a volume approximately corresponding to the remaining empty volume of said first flexible collapsible container, said second container having a piercing spike positioned in said sleeve in sealingly-entered and diaphragm-rupturing relationship therewith, for transfer of the contents between said containers.
Claim 2
Dependent Claim
167 words
A flexible, collapsible container, carrying therewith a volume of solution comprising from 30 to 70 percent of the holding capacity of said collapsible container, said solution being selected from the group consisting of a carbohydrate parenteral solution and an amino acid nutrient parenteral solution, said container defining at least a pair of access ports, one of the ports being sealingly connected to a flexible, crimpable, thermoplastic tubing length of at least 11/2 inches, and a sealed connector member carried on the outer end of said flexible thermoplastic tubing, said sealed connector member defining a sleeve including a sealing diaphragm in the bore thereof, said sleeve constituting an extension of said flexible thermoplastic tubing, and a second container which includes the other type of said parenteral solutions in a volume approximately corresponding to the remaining empty volume of said first flexible collapsible container, said second container having a piercing spike positioned in said sleeve in sealingly-entered and diaphragm-rupturing relationship therewith, for transfer of the contents between said containers.
Claim 3
Dependent Claim
66 words
The collapsible bag of claim 9 in which said sleeve comprises a first sleeve member of larger inner diameter sealingly fitting about the outer end of said flexible thermoplastic tubing, said first sleeve member communicating in telescopic relation with a second sleeve, said second sleeve fitting in the bore of said first sleeve member, and said diaphragm being positioned within the bore of said second sleeve.
Claim 4
Dependent Claim
27 words
The collapsible bag of claim 2 in which said diaphragm within the bore of said second sleeve is positioned adjacent the outer end of said first sleeve.
Claim 5
Dependent Claim
54 words
The flexible, collapsible container system of claim 1 in which said first container initially contains essentially 50 percent by volume of a glucose solution and said second container initially carries essentially 50 percent by volume of said protein based nutrient solution in a volume suitable to be received and held by said first container.
Claim 6
Dependent Claim
36 words
The flexible, collapsible container system of claim 1 in which said first container is a collapsible bag of polyvinyl chloride plastic and the second container is flat-collapsible and wedge-shaped in its initial form, prior to collapse.
Claim 7
Dependent Claim
16 words
The flexible, collapsible container of claim 1 in which said second container is flexible and collapsible.
