Abstract: A sterilization apparatus for use with a cardioplegia heat exchanger device includes an enclosure having an internal volume defined between two ends and a wall. The first end includes a bulb access port, an inlet port formed proximate to or in the first end, a biofilm sterilizing port, and an outlet port formed proximate to or in the second end. A quartz sleeve and an ultraviolet bulb project inwardly into the internal volume from proximate the bulb access port. The ultraviolet bulb illuminates to radiate water entering the inlet port and flowing towards the outlet port between the cylindrical wall and the quartz sleeve. A wiper ring may be slidably fixed around the quartz sleeve for cleaning. In an alternate embodiment, the bulb access port is formed through a water tank of the cardioplegia heat exchanger device with the quartz sleeve and bulb projecting inwardly into the water tank.

Abstract: A urinary funnel has proximal and distal openings and is preferably made from a resilient web scored to define two side panels foldable at a lower fold line that attach mutually together at a top flap. The funnel is collapsible so as to be carried in a wallet or purse. At least one biological indicator is fixed with the inner surface of the funnel structure proximate the distal opening for detecting the use of illicit drugs, pregnancy, or other biological conditions. The web may further includes a transverse slot proximate the lower fold line that is adapted to receive a biological indicator test strip therethrough. The biological indicator is applied to the biological indicator test strip that is in turn positioned through the transverse slot to rest against the inner surface of the funnel structure within the stream of urine flowing from the proximal opening to the distal opening.
