Abstract
Abstract A medicament container/dispenser assembly includes a substantially non-collapsible main body defining a chamber for containing the medicament in liquid form, the main body having an upper portion and a lower portion; an opening formed in the upper portion; a liquid impervious, gas permeable membrane secured to the upper portion of the main body in sealing relation to the opening; a rupturable exit port formed in the lower portion of the main body. The assembly may also include a second opening formed in the upper portion of the main body in spaced relation to the first-mentioned opening and an elastomeric, puncturable, sealing material secured to the upper portion of the main body in sealing relation to the second opening. In a further embodiment, a conduit may be positioned adjacent the membrane at the upper section of the main body, and may contain a blower for supplying forced air to the membrane through the conduit. A sensing device for sensing flow of the liquid medicament from the exit port and for controlling the blower in response thereto may be associated with the blower, in order to selectively activate the blower to maintain a substantially constant flow of medicament from the exit port.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A disposable container/dispenser assembly for the extended storage and direct intravenous administration of a medicament comprising; a substantially non-collapsible main body defining a chamber for containing said medicament in liquid form, said main body being prepared from a medical grade polypropylene-containing molding resin and having an upper portion and a lower portion; pressure equalizing means consisting essentially of a liquid impervious, gas permeable membrane prepared from a material selected from the group consisting of polypropylene, nylon, and polysulfone, said membrane permanently attached to the upper portion of said main body; and an exit port consisting of a tube extending from the lower portion of said main body and having a rupturable closed end.
Claim 2
Dependent Claim
113 words
A disposable container/dispenser assembly for the extended storage and direct intravenous administration of a medicament comprising; a substantially non-collapsible main body defining a chamber for containing said medicament in liquid form, said main body being prepared from a medical grade polypropylene-containing molding resin and having an upper portion and a lower portion; pressure equalizing means consisting essentially of a liquid impervious, gas permeable membrane prepared from a material selected from the group consisting of polypropylene, nylon, and polysulfone, said membrane permanently attached to the upper portion of said main body; and an exit port consisting of a tube extending from the lower portion of said main body and having a rupturable closed end.
Claim 3
Dependent Claim
49 words
A medicament container/dispenser assembly according to claim 1; further including an opening formed in the upper portion of said main body in spaced relation to said pressure equalizing means, and an elastomeric, puncturable, sealing material secured to the upper portion of said main body in sealing relation to opening.
Claim 4
Dependent Claim
50 words
A medicament container/dispenser assembly according to claim 2; further including a secondary container for holding and dispensing an unstable drug in diluted form, and fluid-tight connector means for joining said secondary container and said main body to permit said unstable drug to be placed in solution in preparation for administration.
Claim 5
Dependent Claim
28 words
A medicament container/dispenser assembly according to claim 3; wherein said secondary container and said connector means are adapted to communicate with said main body through said sealing material.
Claim 6
Dependent Claim
64 words
A medicament container/dispenser assembly according to claim 4; wherein said connector means comprises an integral spout extending from said secondary container defining a needle-like point at the free end thereof having a break-away tip seal to retain the medicament in said secondary container, said connector means adapted to be thrust into fluid-tight engagement with said sealing material after said break-away tip seal is removed.
Claim 7
Dependent Claim
21 words
A medicament container/dispenser assembly according to claim 1; wherein said lower portion has a tapered configuration, ending in said exit port.
Claim 8
Dependent Claim
22 words
A medicament container/dispenser assembly according to claim 6; wherein said lower portion terminates in a flat end which forms said exit port.
Claim 9
Dependent Claim
22 words
A medicament container/dispenser assembly according to claim 1; further including connector means in fluid communication with said chamber for containing a drug.
Claim 10
Dependent Claim
46 words
A medicament container/dispenser assembly according to claim 8; wherein said connector means includes a T-shaped connector having a first leg in fluid communication with said chamber through said opening, and a deformable ampule container in fluid communication with said leg for containing a medicament ampule therein.
Claim 11
Dependent Claim
28 words
A medicament container/dispenser assembly according to claim 9; further including screen means positioned in said chamber to prevent pieces of said ampule from passing through said exit port.
Claim 12
Dependent Claim
36 words
A medicament container according to claim 1; further including a conduit positioned adjacent said membrane at the upper section of said main body, and blower means for supplying forced air to said membrane through said conduit.
Claim 13
Dependent Claim
32 words
A medicament container/dispenser assembly according to claim 11; further including sensing means for sensing pressure of said liquid medicament from said exit port and for controlling said blower means in response thereto.
Claim 14
Dependent Claim
32 words
A medicament container/dispenser assembly according to claim 11; further including sensing means for sensing flow of said liquid medicament from said exit port and for controlling said blower means in response thereto.
