Abstract: A bedpan liner, kit and method is disclosed which allows reuse of a conventional bedpan without sterilization, and provides for clean efficient handling of bedpan wastes. The liner is a sheet of water impermeable flexible plastic material which is gathered at opposite ends and secured in the gathered condition to form an elongated hammock-like pouch with relatively rigid end portions suitable for handgripping to carry and dump the pouch. The pouch or liner has convoluted walls that can be approximately formed to the basin in a bedpan. Adhesive tabs attached to opposite ends of the pouch serve to temporarily secure the pouch to the bedpan. Tissue like paper napkins, separable from the pouch, absorb fluid wastes, reduce malodor and conceal the wastes from a person utilizing the liner, kit and method. After removing the liner from the bedpan, tension applied between the ends thereof causes the walls to contract and hold the wastes in a sling or hammock-like manner.

Abstract: An air circulating console is disclosed which produces an ultra clean area suitable for performing surgical operations by first removing bacteria from the air and then forcing this ultra clean air at low velocity and in laminar fashion horizontally from the console to engulf an operation table, surgical team and associated equipment. The effective zone of ultra clean air is projected over a large area with the assistance of a pair of vertical high velocity air curtains emitted at an angle toward the ultra clean air from a pair of air curtain plenums which protrude from the console on opposite sides thereof. Air is returned to the console via a pair of intake ducts positioned on opposite sides thereof, rearward and outboard of the air curtain plenums. The air flow pattern generated by the console in a closed room exhibits a lifting effect which discourages the settling of bacteria.

Abstract: A unidirectional direct rotary stepper motor is adapted to step its rotor between successive stable rest positions in response to successive electrical pulses of opposite polarity. The motor includes a rotor having a central hub portion and a plurality of annularly aligned similar blades, an energizing coil, and a core which passes through the energizing coil and has a first pole face disposed in close relationship with the rotor hub portion, and a second spaced-apart pole face disposed in close relationship with the rotor blades. An annular array of similar permanent magnets of sequential opposite polarity is disposed on the surface of the core pole opposing the rotor blades in serial intervention in the coil flux path.
