1. Fluid warmer comprising:
- a. flanged air cavity member with at least one hole;
b. windowed membrane having a predetermined open cross section and the same dimensions as said air cavity member;
c. air-permeable membrane having dimensions substantially the same as said air cavity member;
d. flanged chemical cavity member and of the same dimensions as said air cavity member;
e. a quantity chemically reactive mix in said chemical cavity chamber; and
f. an inert atmosphere maintained in said air cavity member and said chemical cavity member by heat sealed flanges and sealing of said hole by said adhesive foil tape, and said adhesive foil tape means covering said hole.

Abstract
A warmer used to warm fluids, such as blood or the like, passed into the human body. Air is introduced through an opened windowed membrane to expose chemicals in a container. A chemical reaction with the air causes a heat reaction of the chemicals. A tube engages in a trough in the container adjacent where the chemical reaction takes place, thereby absorbing the heat of the chemical reaction for warming the fluids, such as blood, saline solution, injectable solutions in trauma, pre-surgical, intra-surgical, post-surgical and any other solutions through the tube.

5. Process of manufacturing a fluid warmer comprising the steps of:
-
a. filling a chemical cavity member with dry chemically reactive powder mix; b. positioning said chemical cavity member, an air-permeable membrane, a windowed membrane, and an air cavity together in alignment about respective perimeters; c. heat sealing said perimeters, thereby forming a flange seal about the warmer; d. flooding said warmer with nitrogen in an inert atmosphere; e. adding water; and
,f. taping and sealing holes in said air cavity.

6. Process of manufacturing a fluid warmer comprising the steps of:
-
a. filling a cavity member with dry chemically reactive powder mix; b. positioning an air-permeable membrane, a windowed membrane in alignment about respective perimeters of said cavity member and securing same; c. containing said warmer in an air tight non-permeable pouch rather than sealing holes in said air cavity; and d. flooding said warmer with nitrogen in an inert atmosphere in a pouch.
