A treatment pad for applying heat, cooling or an antiseptic fluid to a subject's body surface incorporates a heat transfer member or a wound treatment member that is adapted to be held in place by application of a vacuum pressure. The heat transfer member may comprise an electrical resistance wire arranged in a serpentine pattern within a housing or, alternatively, may comprise interconnected heat transmissive tubing through which either a heated or a cooled fluid may be made to pass. Alternatively, the pad may contain a gel that can be cooled in a refrigerator or heated in a microwave oven and held in place on the subject's body by application of a vacuum to the assembly. The wound treatment member may comprise a gaseous antiseptic delivery pad held in place on the patient's body by use of a vacuum.
