Abstract of the Disclosure The disclosure is of a method of forming a waterproof seal about the cast or dressing on a patient. An air- and water-impervious flexible membrane is placed over the cast or dressing to a position where the membrane's edge margins overlie the patient's skin along the perimeter of the cast or dressing. A vacuum is created between the membrane and skin by evacuating air through a suction tube or valve. The vacuum creates a close, snug fit of the membrane over the entirety of the cast or dressing and over a relatively large surface area of skin to provide a waterproof seal.
