A portable, protective enclosure for coupling to a patient support includes a collapsible frame, a canopy drape, a pair of gloves and sleeves configured for receiving hands and arms of a user, and a zipper disposed along one of the side surfaces of the drape, wherein the side surface is not folded about itself when the zipper is in an open state. 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.

Patient isolation system and method

A method is disclosed for packaging a curable resin composition and a catalyst composition that react with each other when mixed, comprising providing a partitioned tube for receiving the resin composition and the curing agent in separate compartments; delivering a stream of a resin composition into one compartment of the tube; delivering a stream of a curing agent in the other compartment of the tube; advancing the partitioned tube and constricting and sealing the partitioned tube at spaced apart intervals and severing the sealed tube to produce a package partitioning the resin composition from the catalyst composition. Solid particulate is continuously added into the stream of at least one of the catalyst composition and the resin composition and mixing the solid particulate and stream to produce a mixed composition; and the relative amount of solid particulate in the mixed composition is controlled by continuously determining the mass of solid particulate added to the mass of the stream.

Resin cartridge production system

System and method for producing resin cartridges

A resin bonded mine roof bolt having an elongated rod with a first end, a second end, and a resin control surface positioned on the rod between the rod first and second ends. The resin control surface has a channel extending along the length of the bolt for distributing resin and interrupted spiral threads for mixing resin. When installed in a mine roof bore hole with curable resin, the resin control surface mixes the resin and partially fills the bore hole to minimize the amount of resin needed to anchor the bolt.
