Abstract: A chemical or biological containment apparatus having a seal to contain contaminants in an inside thereof from passing to an outside, including an outer envelope; a port disposed in the envelope, the port including an outer portion having a circumferential portion extending away from the envelope and a flange extending from the circumferential portion and attached to the envelope, and an inner portion. The inner portion includes a circumferential surface corresponding to the circumferential portion, a plurality of grooves formed in the circumferential surface, and a plurality of O-rings respectively received in the grooves to form the seal with the outer portion.

Abstract: A collapsible, protective containment device isolates a patient in a controlled environment. The containment device has a flexible containment wall, a closure device an air ventilation device and a plurality of ribs. The flexible containment wall is expandable from a collapsed state to define an interior region for receiving at least a portion of a patient therein and providing an impermeable barrier about the portion of the patient, for at least a selected contaminant. The closure device closes the containment wall about the patient to provide a substantially airtight interior region. The air ventilation device provides a gas comprising oxygen to the substantially airtight interior. The plurality of inflatable ribs provided along a length of the containment wall, the inflatable ribs defining one or more air compartments separate from the interior region within the containment wall, the one or more inflatable ribs supporting the containment wall away from the patient.
