Portable fluid administration container with integral heat exchanger
First Claim
1. An infusion administration container for infusing a physiologic fluid into an animal, which comprises:
- a first flexible bladder divided into at least two compartments separated from one another, each of said compartments containing at least one first chemical agent;
a second flexible bladder disposed outside said first flexible bladder and containing at least one second chemical agent, said first and second chemical agents when combined resulting in an exothermic reaction;
passageways interconnecting each of said compartments of said first bladder with said second bladder;
manually openable closure means disposed within each of said passageways;
a third flexible bladder adapted to contain an administrable physiologic fluid and being in a contacting heat-exchange relationship with said second bladder, said first and second chemicals provided in amounts sufficient and said passageways being dimensioned such that when said closure means is opened, said at least one first chemical agent flows into said second flexible bladder at a rate sufficient so that the resulting exothermic reaction with said at least one second chemical agent generates sufficient heat to maintain said physiologic fluid at about 32 degrees to 42 degrees Centigrade for its infusion into said animal; and
fluid conduction means adapted to conduct said physiologic fluid into said animal.

Abstract
The present invention is addressed to providing an infusion administration container which is effective in establishing about a normothermic temperature of a physiologic solution for its infusion into an animal, such as a human medical patient. The infusion administration container comprises an upper flexible bladder adapted to contain at least one first chemical agent and a first lower flexible bladder adapted to contain at least one second chemical agent. These first and second chemical agent(s), when combined, result in an exothermic reaction. A passageway interconnects the upper bladder and first lower bladder with manually openable closure means disposed within the passageway to separate the chemical agents until the closure means is opened. A second lower flexible bladder, adapted to contain an administrable physiologic fluid, is disposed in heat-exchange relationship with the first lower bladder. The passageway is dimensioned such that when the closure means is opened, the first chemical agent(s) flows into the first lower flexible bladder at a rate sufficient so the resulting exothermic reaction generates sufficient heat to maintain the physiologic fluid within a normothermic temperature range for its infusion into the desired patient. The present invention also includes a method of maintaining a physiologic fluid within a normothermic temperature range for its infusion into a desired patient.

10. A method for maintaining a physiologic fluid at about a normothermic temperature for its infusion into an animal which comprises the steps of:
-
(a) providing an infusion administration container which comprises a first flexible bladder divided into at least two compartments separated from one another, each of said compartments containing at least one first chemical agent, a second flexible bladder disposed outside said first flexible bladder and containing at least one second chemical agent wherein said first and second chemical agents when combined result in an exothermic reaction;
there being passageways interconnecting each of said compartments of said first flexible bladder and said second bladder, with manually openable closure means disposed within each of said passageways to separate said at least one first chemical agent in each of said compartments of said first flexible bladder from said at least one second chemical agent until each said closure means is opened, said closure means thereby comprising a series of said closure means, and a third flexible bladder containing an administrable physiologic fluid, and said third flexible bladder being in a contacting heat exchange relationship with said second flexible bladder and said third flexible bladder containing fluid conduction means adapted to conduct said physiologic fluid into said animal; and(b) opening each said closure means of said series in sequence, so that the resulting exothermic reaction generates sufficient heat to maintain the physiologic fluid at about 32 degrees to 42 degrees Centigrade for its infusion into said animal; and
`allowing said physiologic fluid to flow through said fluid conduction means into said animal. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
