ABSTRACT:
An apparatus and method is disclosed for an improved absorbent pad and thermal pack for absorbing a liquid discharged from a patient. The absorbent pad and thermal pad comprises an outer sheet made of a liquid impermeable material and an inner sheet of a liquid permeable material. An absorbent sheet is disposed between the inner sheet and the outer sheet. A flexible liquid impermeable container having a chemical mixture which undergoes an thermal reaction upon activation thereof is interposed between the outer and inner sheets to enable the thermal source to be applied to the patient and to enable any liquid from the patient to permeate through the inner sheet to be absorbed by the absorbent sheet. The inner sheet of a liquid permeable material provides a moderate insulation barrier whereas the absorbent pad provides a substantial insulation barrier for directing the thermal source to the patient.
