  • Publication number: 20130303844
    Abstract: A disposable air/water valve may include a main stem providing an air passage through the center bore of the main stem. A method for manufacturing a disposable air/water valve may include several steps. The main stem is molded, and placed in a mold for over-molding seals onto the main stem. Prior to the next steps, the retaining ring, button cap, and boot may be molded. The back end of the main step is placed through the center of the retaining ring and resilient member (e.g. spring). The button cap is then placed on and secured to the main stem.

  • Publication number: 20120301356
    Abstract: A system for decontaminating a medical device includes a decontamination chamber configured to retain the medical device and a chemical dispersion assembly configured to deliver a decontaminating fluid to the decontamination chamber. A pressure control assembly is connected to the decontamination chamber and configured to control the pressure in the decontamination chamber. The system also includes a system controller configured to control the decontamination chamber, chemical dispersion assembly, and pressure control assembly. A pressure in the decontamination chamber is reduced to within a sub-atmospheric pressure range in a first evacuation step and add a decontaminating fluid into the decontamination chamber at a first rate while increasing the pressure in the decontamination chamber. Adding the decontaminating fluid increases a relative humidity in the decontamination chamber to a level that improves the efficacy of the decontaminating fluid.

  • Publication number: 20110091354
    Abstract: A system for disinfecting a room includes an enclosure having first and second air inlets and an air intake control assembly to selectably control air flow into the enclosure through the first and second air inlets. Air that flows between the exterior and interior of the enclosure through the second air inlet passes through a filter assembly. The enclosure also includes an air dispersion outlet having a fan that draws air into the enclosure through the first and second air inlets and forces air out of the enclosure. A chemical dispersion assembly generates a disinfecting fog relative to the fan. A system controller controls the air intake control assembly to disperse the disinfecting fog into the room, and subsequently draw the disinfecting fog from the room and through the filter assembly.

  • Patent number: 6830367
    Abstract: A low-profile tank and system for mixing dry chemicals with water to form a concentrated hemodialysis solution, the tank having a fluid supply nozzle projecting into a cylindrical side wall of the tank, and a drain connection at an apex of a conical bottom wall of the tank. A cavity having a ramp-like bottom wall extends from the cylindrical side wall of the tank. A venturi eductor provides for transfer of dry chemicals to the tank using compressed air to aspirate the chemicals and deliver them to the tank. A plurality of load cells may be used to measure the weight of the tank and contents. Manual transfer of dry chemicals to the tank is facilitated by the low profile of the tank. A tapered shipping container is provided for nesting when empty.
