  • Patent number: 8277748
    Abstract: A container for enabling fluid flow therethrough for cleaning or sterilizing of the contents, comprises a tray (10) and lid (20) and having respective bases (11, 21) and side walls (17, 27). The bases (11, 21) have perforations (12, 22) defined by elliptically shaped perforation walls (13, 23) with their major axes vertical to allow easy flow of the cleaning fluid through the container and minimum contact points with the contents or other containers. The internal corners (30) of the perforations (12, 22) in horizontal sections are smoothly curved to minimize debris or deposits collecting and resisting removal. A method of cleaning or sterilizing using the container is also described.

  • Patent number: 5964004
    Abstract: The invention relates to tube cleaners for hygienic cleaning of tubes, e.g. endoscopic tubes. A first embodiment has a body made of resilient material extending axially and having a socket at one end for mounting of the cleaner to the end of the rod. Integral blades project out from the body, each blade having an arcuate outer edge to scrape along the inside wall of the tube. The blades are at axially spaced locations and, in end view, they overlap so that cleaning occurs around 360.degree.. A second embodiment has a core such as a wire, and the body and integral blades are moulded onto the wire core.
