The Deltaphase® Isothermal Pad is a new
approach to body temperature stabilization. It acts as a source of heat,
but cannot overheat . Its constant
temperature is based on a thermodynamic principle and needs no
electricity or wires, no thermostat or feedback controller. It cannot
generate electrical signals or cause interference. It cannot trigger an
explosion. It can maintain a small animal at near normal and constant
temperature for several hours. The Deltaphase® Isothermal Pad is
based on the thermodynamic principle that a heat releasing phase change
is isothermal, that is: that it occurs at constant temperature. A unique
chemical solution is contained within a durable pouch. At room
temperature this solution is in solid form. When heated to 39° the
solution becomes fluid. In this state, the pad is activated and ready
for use. |
Maintains animals or
cultures
at 37 degrees C for hours.
Ideal for NMR !
|
When an animal (or any cooler object) is
placed in contact with the activated pad, heat leaves the solution as it
undergoes a phase change back to the solid form. In this phase change,
over 30 calories of heat are released per gram of solution, even though
the temperature is constant. The pad remains isothermal until all the
liquid phase has solidified. Only then does its temperature fall. The
transition temperature has been preset to 39° so that a small
temperature gradient always exists for heat flow from pad to animal.
This heat flow balances heat losses and maintains animal body
temperature near 39° for periods up to several hours.

Deltaphase®
Operating Board |
|
|
This compact operating board takes advantage
of the Deltaphase principle to maintain animal body temperature during
surgical or experimental procedures. An eight and one half inch square
stainless steel operating surface lies in contact with an activated
Deltaphase® isothermal pad. The underside of the pad is insulated to
provide a longer isothermal period. |
 |
Molded wells are provided for sponges, instruments and anesthetic
apparatus. The board is functional, durable, and easy to clean. Its low
cost and safety make it appropriate for use in student laboratories. The
unit is supplied with two Deltaphase® pads.
