Patent number: 4975186Abstract: Blood and blood component container having in continuous communication therewith a receptacle adapted to receive and define a given component or sub-component when contents in the container are separated. In preferred embodiments, the container is a flexible bag having a tapered portion adjacent the receptacle to assist migration of a given component or sub-component into the receptacle during centrifugation and at least a portion of the container is supported by a cup-like device, the inner surface of which conforms to the outer surface of the bag and communicating receptacle.Type: GrantFiled: November 29, 1985Date of Patent: December 4, 1990Assignee: Miles Laboratories, Inc.Inventors: Shohachi Wada, Bruce Kuhlemann

Patent number: 4969882Abstract: A generally flat, elongated edge-sealed polymeric blood bag having a length to width ratio of at least 2 to 1 and one end portion in tapering communication with a connected tubing. When the bag is filled with a mixture of blood components which are then separated, the tapering end portion expands to form a funnel-like guide for directing a separated component from the bag through the tubing in a substantially unobstructed manner. Bag is especially useful for separating and isolating the components of a neocyte/gerocyte red blood cell mixture.Type: GrantFiled: June 27, 1986Date of Patent: November 13, 1990Assignee: Miles Laboratories, Inc.Inventors: Raleigh A.

Patent number: 4954450Abstract: Disclosed is a method of growing a mixture of two or more species of lactic acid producing bacteria whose growth rates are differently affected by the pH of the nutrient growth medium. The method involves maintaining the pH of the medium at a low level which actively selects for the growth of one species until that species has reached the desired concentration. The pH is then raised to a level that actively selects for the growth of another species and maintained at this level until that species has reached the desired concentration. The method is especially useful for preparing a starter culture for Italian type cheese containing a mixture of coccus and rod bacteria because the ratio of these bacteria, one to the other, can be closely controlled.Type: GrantFiled: August 17, 1987Date of Patent: September 4, 1990Assignee: Miles Laboratories, Inc.Inventors: Carl F. Brothersen, Willard R. W. Knoespel

Patent number: 4938744Abstract: Double-protected needle assembly comprising a needle-handle portion and a needle-protecting portion. The needle-handle portion includes a bevel-tipped needle attached to and extending from it into the needle-protector portion. The needle protecting portion comprises a rigid, tamper proof member completely enclosing the needle and attached to the needle-handle portion at a resilient tear seal member adapted to break when a twisting force is applied to either the handle portion or the protecting member. The tear seal is adapted to remove liquid from the surface of the needle when the protector is withdrawn to expose the needle. Within the protector, but not attached thereto, is a relatively soft inner tubular enclosure completely enclosing the needle extending beyond its bevel tip and adapted to prevent contact of the bevel tip with any portion of the rigid protector during assembly or when the protector is removed.Type: GrantFiled: February 8, 1985Date of Patent: July 3, 1990Assignee: Miles Laboratories, Inc.Inventors: Prentice C. Wharff, Renato R. Salumbides

Patent number: 4850993Abstract: A method and system is disclosed for introducing anti-bacterial agents, for example, quinolone carboxylic acid derivatives into blood bag systems for preventing massive bacteria growth in stored blood and blood components. The quinolone carboxylic acid derivative can be added to a collection container before, during or after the collection of blood and blood components. The addition of a quinolone carboxylic acid derivative to blood bag systems allows for increase in storage time for blood and blood components without the threat of massive bacterial contamination.Type: GrantFiled: December 22, 1986Date of Patent: July 25, 1989Assignee: Miles Laboratories, Inc.Inventors: Alexander B.

Patent number: 4801450Abstract: Normal plasma from donors who have not been vaccinated with a P seudomonas vaccine or had a Pseudomonas infection can be screened for higher than normal titers of naturally occurring antibody to four or, preferably, two of seven Fisher Immunotypes of Pseudomonas. Those plasmas with higher titers of such antibody can be pooled and fractionated to give hyperimmune serum globulin having high titers of antibody against all seven Fisher Immunotypes. The product may be treated to render it intravenously injectable and the so-prepared material is effective in treating patients with Pseudomonas infection. Also disclosed is a novel antibody preparation including minimum titers of the seven Fisher Immunotypes.Type: GrantFiled: May 5, 1986Date of Patent: January 31, 1989Assignee: Miles Laboratories, Inc.Inventors: Michael S.
