摘要

Apparatus and methods of their use are described herein. In an aspect, an apparatus includes: a structure defining an aperture at an engagement surface configured to reversibly seal to a 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 oriented to maintain a non-turbulent gas flow traversing at least a part of the surface on the individual body; one or more gas outlets distally positioned on the structure from the one or more gas inlets, the one or more outlets configured to release a gas from the isolation field while maintaining a positive pressure in the isolation field relative to the outside environment of the structure; and at least one sealable access site.
