Abstract A disposable plastic cover for inflatable anti-shock trousers prevents contamination of the trousers in use. The trousers need not be washed or decontaminated between uses. The cover engages the trousers firmly on the inside and provides the same securing means on its outer surfaces for holding tightly around the patient when the trousers are inflated to pressurize the lower body to prevent shock.
