Abstract:
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;an absorbent sheet having an inner surface and an outer surface;said inner surface of said outer sheet portion being connected to said inner surface of said inner sheet portion enclosing said absorbent sheet for enabling any liquid from the patient to permeate through said inner sheet portion to be absorbed by said absorbent sheet;a thermal pack comprising a flexible liquid impermeable container comprising a chemical mixture which undergoes a thermal reaction upon activation of the chemical mixture;said inner sheet portion retaining said thermal pack with said inner sheet portion interposed between said absorbent sheet and the patient for enabling said thermal pack to cool said patient; andsaid absorbent sheet being greater in thickness than said inner sheet portion for providing a substantial thermal barrier which is substantially greater than a moderate thermal barrier of said inner sheet portion to establish a substantial thermal insulator between said thermal pack and a temperature of ambient air 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.
