ISOLATOR FOR USE IN SURGERY.

摘要

An isolator and method of using it for providing a contamination-free atmosphere in which a surgical procedure can be performed or equipment that is sensitive to environmental contamination can be assembled. The isolator includes an inflatable bag (10) of flexible material through which filtered air is pumped to continuously change the air and maintain a positive pressure in the bag. For use in surgery, a portion of the lower side is made of a surgical drape material (30) of elastic material to allow a body member upon which a surgical procedure is to be performed to be pulled into the work space of the bag through an incision in the drape that is smaller than the member to cause the stretched elastic material to tightly surround the member and reduce the chances of disease organisms from entering the work space from outside the bubble.
