20090112298 | HIGH EFFICIENCY THERMAL ENERGY TRANSFER PAD - A thermal energy transfer pad is disclosed. The thermal energy transfer pad has a first flexible, thermal energy transfer sheet and a second flexible, thermal energy transfer sheet. The first flexible, thermal energy transfer sheet (a) is made of a first fluid impervious material, (b) has a perimeter measurement of A prior to manufacturing and (c) has a first thermal energy transfer thickness. The first flexible, thermal energy transfer sheet is molded to form fluid path troughs defined by interior protuberances and the first sheet's perimeter edge. That molding alters the first flexible, thermal energy transfer sheet's perimeter measurement to B, which is less than A. The second thermal energy transfer sheet (a) is made of a second fluid impervious material, (b) has a perimeter measurement of B and (c) has a second thermal energy transfer thickness. The second thermal energy transfer sheet is sealed to the first thermal energy transfer sheet along the first sheet's perimeter and at the first sheet's interior protuberances. That sealing creates a tortuous fluid path in the fluid path troughs The resulting pad has a significantly (1) decreased chance of the fluid being occluded in the fluid path and (2) increased thermal energy transfer rate to the patient. | 04-30-2009 |
