Patent number: 4844245Abstract: A closure is provided comprised of a thin flexible material for use on a needle disposal container so that a contaminated blood collection needle may be removed from its holder and deposited in the container without the user touching the needle or the needle hub. The device includes dual elongated tapered openings to accommodate varying diameters of needle hubs. By having dual openings, the useful life of the cap and its associated container is doubled. The cap of the invention is configured to be utilized with a large variety of collection containers of varying sizes and shapes. A feature of the invention includes chamfered surfaces at the enlarged end of each of the dual openings to provide a sharp edge which is useful for urging a needle hub out of its holder, without physically touching the needle or hub.Type: GrantFiled: January 17, 1989Date of Patent: July 4, 1989Assignee: Becton, Dickinson and CompanyInventor: Michael C. Bennett

Patent number: 4626359Abstract: A deep bed filter of the type comprising an upright vessel of particulate filter medium, inlet means at the top of the vessel for introduction of an aqueous stream to be filtered, outlet means at the bottom for removal of filtered liquid and means for backwashing the medium by an upward flow of liquid, has as the filter medium bone char and sand, the bone char being located substantially above the sand. The sand generally comprises a particulate mineral filter material selected from silica sand, fused alumina, garnet, zircon, ilmenite and glass.Type: GrantFiled: June 3, 1985Date of Patent: December 2, 1986Assignee: Tate & Lyle Public Limited CompanyInventors: Michael C. Bennett, Nicholas Coote, Andrew Byers

Patent number: 4147628Abstract: The disclosure is of an improved method and apparatus for separating blood into light, substantially liquid phase and its heavy, substantially cellular phase by centrifuging a blood filled container having disposed therein an inert, gel-like barrier material possessing a density intermediate between the two phases of the blood. The improvement comprises employing a constricted tubular container, the constriction being at the zone where it is calculated the gel-like barrier material will align during centrifugation.Type: GrantFiled: January 23, 1978Date of Patent: April 3, 1979Assignee: Becton, Dickinson and CompanyInventors: Michael C. Bennett, Suresh N. Mehta
