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.
