Claim:
An apparatus, comprising: a structure defining an aperture at an engagement surface, the structure configured to reversibly seal proximate to a wound surface on an individual body, and further defining an isolation field; at least one gas port; one or more gas inlets operably attached to the at least one gas port, the one or more gas inlets positioned proximate to the engagement surface and oriented to maintain a non-turbulent gas flow traversing at least a part of the wound surface on the individual body to direct particulate matter away from the wound surface; one or more gas outlets distally positioned on the structure from the one or more gas inlets to receive the particulate matter directed away from the wound surface by the non-turbulent gas flow, the one or more gas outlets configured to release a gas from the isolation field while maintaining positive pressure in the isolation field relative to an outside environment of the structure; and at least one sealable access site.
