Abstract: A robotic surface cleaning device is disclosed. The robotic surface cleaning device may be configured to traverse over a floor surface in a room area to disinfect various surface as well as disinfect the air in the room. The robotic surface cleaning device may include a maneuvering base. The robotic surface cleaning device may also include a support tower coupled to the maneuvering base and at least one deployable structure attached to the support tower, wherein the at least one deployable structure is capable of extending and retracting to pass over surfaces in the room area. The at least one deployable structure may include one or more ultraviolet (UV) light source configured to disinfect the surfaces in the room area. The support tower may include at least one air inflow vent configured to draw in room air, at least one air sanitizing unit configured with at least one array of UV light emitting diodes (LEDs), and at least one discharge vent configured to emit sanitized air.

Abstract: The disclosure is of a method for preparing a stable, dry-packaged, sterile, nutrient composition which upon addition of sterile, pyrogen-free water is suitable for intravenous administration to a mammal, including a human. The method comprises providing the nutrients in a specific dry form and state of physical purity acceptable for intravenous administration, sealing the nutrients in a particular type of container adapted to receive and dispense sterile fluids and subjecting the container and its sealed contents to a sterilizing, nondestructive dose of ionizing radiation. The method results in a packaged, sterile nutrient composition which may be dissolved by the addition of sterile, pyrogen-free, water. The resulting aqueous intravenous solution may be safely administered to a mammal, including a human, in need of nutrient therapy.
