Patient table with heated pad

A pad for a patient operating table, the pad comprising:

• an outer shell including a bottom shell surface for connection to said patient operating table and a top shell surface for supporting a patient;
• a cell defined within the outer shell;
• at least one cushion located in the cell;
• at least one heating element located in the cell between the at least one cushion and the top shell surface, the at least one heating element including a radiant plate formed of a conductive material and a diffusive plate located between the top shell surface and the radiant plate, wherein the at least one cushion is formed of a first foam material and the diffusive plate is formed of a second foam material that is more dense than the first foam material;
• and
• at least one vent connected to the outer shell with a hermetic seal, wherein the at least one vent includes a filtering membrane that permits a passage of air and blocks a passage of at least one pathogen.

• at least one heating element located in the cell between the at least one cushion and the top shell surface, the at least one heating element including a diffusive plate formed of a thermally diffusive material that is sandwiched between the at least one cushion and a radiant plate formed of a conductive material, wherein the at least one cushion is formed of a material with less thermal diffusivity than the thermally diffusive material;
• and
• at least one vent connected to the outer shell with a hermetic seal, wherein the at least one vent includes a filtering membrane that permits a passage of air and blocks a passage of at least one pathogen.
