A pair of filters are disposed on opposing sides of one of the side surfaces of the canopy drape, the filters together providing high efficiency particulate air filtration for at least 99.97% of airborne particulate 0.3 microns in diameter. Gas-permeable media is provided for air intake. A fan in communication with the first and second filters is provided for creating negative pressure in the internal region of the canopy drape, the fan configured to evacuate air from the internal region. A negative pressure indicator also is included. ## Claims ### Claim 1 A portable, protective enclosure for coupling to a patient support for supporting a mammal comprising: a collapsible frame comprising a pair of X-shaped linkages coupled with a pair of cross-members; a canopy drape formed of a transparent, first polymeric material, the canopy drape being bottomless and having a top surface, a plurality of side surfaces, an internal region disposed between the top and side surfaces, an air intake portion, and a first thickness, wherein the canopy drape is coupled to at least one of the cross-members; a pair of sleeves and gloves configured for receiving hands and arms of a user, the sleeves and gloves together having a closed, first free end, an open, second free end, and a second thickness, wherein the sleeves are coupled to the canopy drape to form an air-tight seal therebetween and the second thickness is less than the first thickness; a zipper disposed along one of the side surfaces, the zipper having a closed state and an open state, wherein the side surface is not folded about itself when the zipper is in the open state; a first filter disposed in communication with a second filter, the first and second filters disposed on opposing sides of one of the side surfaces of the canopy drape, wherein the first and second filters together provide high efficiency particulate air filtration to filter at least 99.97% of airborne particulate of 0.3 μm in diameter; gas-permeable media disposed in communication with and proximate the air intake portion; a movable fan in communication with the first and second filters for creating a negative pressure of at least 0.01 inches of water in the internal region of the canopy drape, the fan configured to draw in air through the gas-permeable media into the internal region and evacuate air from the internal region through the first and second filters; and a negative pressure indicator. ### Claim 2 (depends on 1) The enclosure of claim 1, wherein the first polymeric material is thermoplastic polyurethane and the first thickness is 10 mils. ### Claim 3 (depends on 1) The enclosure of claim 1, wherein at least one of the sleeves and the gloves is formed of a second polymeric material, the second polymeric material is thermoplastic polyurethane and is transparent, and the second thickness is 2 mils. ### Claim 4 (depends on 3) The enclosure of claim 3, wherein the negative pressure indicator comprises an expandable vessel coupled to the canopy drape and the expandable vessel is formed of the second polymeric material. ### Claim 5 (depends on 1) The enclosure of claim 1, wherein the sleeves are coupled to the canopy drape by a coupling selected from the group consisting of welds, bonds, or mechanical connections. ### Claim 6 (depends on 5) The enclosure of claim 5, wherein the coupling further comprises seam tape. ### Claim 7 (depends on 1) The enclosure of claim 1, wherein a plurality of grommets are disposed proximate the top surface of the canopy drape. ### Claim 8 (depends on 1) The enclosure of claim 1, wherein the canopy drape is coupled to both of the cross-members. ### Claim 9 (depends on 1) The enclosure of claim 1, wherein the fan provides a flow rate of air from the internal region of the canopy drape of between 70 cfm and 100 cfm. ### Claim 10 (depends on 1) The enclosure of claim 1, further comprising a control system to maintain the negative pressure of at least 0.01 inches of water in the internal region. ### Claim 11 (depends on 1) The enclosure of claim 1, wherein the internal region has a volume of between about 25 cubic feet and about 125 cubic feet. ### Claim 12 (depends on 1) The enclosure of claim 1, wherein the negative pressure indicator comprises an expandable vessel coupled to the canopy drape. ### Claim 13 (depends on 12) The enclosure of claim 12, wherein the expandable vessel comprises indicia for indicating when desired pressure is reached. ### Claim 14 (depends on 12) The enclosure of claim 12, wherein the expandable vessel is sealingly coupled to a side surface of the canopy drape. ### Claim 15 (depends on 1) The enclosure of claim 1, wherein the first and second filters together provide high efficiency particulate air filtration to filter at least 99.99% of airborne particulate of 0.3 μm in diameter.
