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 a 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.

An improved absorbent pad and thermal pack for absorbing a liquid discharged from a patient, comprising in combination: an outer sheet portion and an inner sheet portion; said outer sheet portion having an outer surface and an inner surface; said inner sheet portion having an outer surface and an inner surface with said inner sheet portion being made of a liquid permeable material; said inner sheet portion providing a moderate thermal barrier; an absorbent sheet having an inner surface and an outer surface; said absorbent sheet being greater in thickness than said inner sheet portion for providing a substantial thermal barrier which is substantially greater than the moderate thermal barrier of said inner sheet portion; a thermal pack comprising a flexible liquid impermeable container containing a chemical mixture which undergoes a thermal reaction upon activation of the chemical mixture; said outer sheet portion being connected to said inner sheet portion for enclosing said thermal pack and said absorbent sheet with said thermal pack being interposed between said absorbent sheet and said inner sheet portion; said inner sheet portion enabling said thermal pack to cool said patient and with said liquid permeable material of said inner sheet portion enabling any liquid from the patient to permeate through said inner sheet portion to be absorbed by said absorbent sheet; said absorbent sheet establishing a substantial thermal insulator between said thermal pack and a temperature of ambient air and with said inner sheet portion establishing a moderate thermal insulator between said thermal pack and the patient for providing a preferential flow of heat between the patient and said thermal pack relative to the flow of heat between the ambient air and the thermal pack; and said inner sheet portion being substantially thinner than said absorbent sheet and being the sole sheet interposed between said thermal pack and the patient for allowing the liquid discharged from the patient to migrate through said inner sheet portion to said absorbent sheet wherein the majority of the liquid discharged from the patient is absorbed by said absorbent sheet.
