1. In a patient treatment environment, a controlled access aerosolized particle enclosure device for isolation of airborne contaminants, comprising:
a frame defining a patient isolation region having a patient treatment surface;
a linkage for attaching the frame to a patient treatment vehicle;
a flexible barrier defining an enclosure suspended by the frame enclosing the patient isolation region, the barrier formed from deformable planar sheets of a flexible transparent material and extending adjacent to the patient treatment surface;
a low pressure source in fluidic engagement with the enclosure for reducing a pressure within the enclosure below that of ambient surroundings, the low pressure source providing a pressure for drawing the flexible barrier against the patient treatment surface for restricting airborne particle passage from the enclosure to the ambient surroundings, the low pressure source providing a suction force for drawing the flexible barrier against the patient treatment surface for maintaining a negative pressure within the enclosure while retaining the enclosure from deformation and incursion into the patient isolation region; and
at least one access port on the flexible barrier,
the at least one access port including:
an inner drape attached to an inner surface of the flexible barrier at an overlapping portion; and
a separable seam in the flexible barrier along the overlapping portion, the separable seam continuous with the flexible barrier along a bottom edge and configured for release for folding downward.
