Patent number: 6440110Abstract: An apparatus and method for collecting a large volume of blood from an umbilical cord in a sterile environment are shown and described. A housing having an inner region adapted to retain an umbilical cord in a desired location is provided, the housing having an opening through which the cord extends from the inner region of the housing to a region external to the housing. The cord is cut by a blade coupled to the housing, either by the motion of the blade from a first position to a second position, or by the movement of two portions of the housing from a first extended position to a second collapsed position. The newly cut end of the umbilical cord falls and hangs freely in the inner region of the housing, blood flowing from the placenta and umbilical cord via gravity into a blood collection region of the housing. The blood collection region may be flexible, and may be coupled to a conventional blood collection bag.Type: GrantFiled: December 18, 2000Date of Patent: August 27, 2002Assignee: Children's Hospital Medical Center of Northern CaliforniaInventors: Franciscus A.

Patent number: 5056682Abstract: A container for carrying a uniform, fan-folded stack of plastic sheet assemblies and for allowing the assemblies to be conveniently dispensed, one at a time, with minimal risk that the stack will become jammed. The stack of assemblies is retained behind a constriction within an elongated chamber having a corresponding shape and slightly larger size. Pulling the forward-most assembly through a narrow channel and exit slot at the forward end of the container flexes a trailing assembly past the constriction, while the remaining assemblies remain retained behind the constriction. In addition, a shallow recess in a wall defining the narrow channel conformingly receives a plastic sheet assembly in position to be dispensed, with the recess' rear periphery inhibiting the assembly from being moved unintentionally back into the chamber.Type: GrantFiled: December 12, 1989Date of Patent: October 15, 1991Assignee: Diatek IncorporatedInventors: Richard P. Meyst, Joseph J. Manno, Jimmy J. Carlock, Ian F. Ayton, Thomas K. Gregory, Edward D. Suszynski

Patent number: 4911559Abstract: A probe cover assembly for use in covering and protecting the elongated probe of a medical thermometer. The assembly has three laminated layers, including a flat base layer with an aperture sized to slide over the probe, an intermediate stretchable film, and a protective paper layer having radially-aligned perforations aligned with the base layer aperture. In use, the probe cover assembly is placed on the probe by inserting the probe through the base layer aperture, from the assembly's paper layer side, to stretch the plastic film over the probe, with the perforated paper functioning initially to separate the probe from the film and thereby prevent the film from initially sticking to the probe and stretching unevenly. The probe cover assembly is removed from the probe and discarded by sliding the apertured base layer along the probe, with the perforated paper functioning to scrape the stretched film from the probe.Type: GrantFiled: November 1, 1988Date of Patent: March 27, 1990Assignee: Diatek, Inc.Inventors: Richard P. Meyst, Edward D. Suszynski

Patent number: 4736736Abstract: An improved cervical traction apparatus comprises a cradle including a bowl-shaped cranial cavity for supporting the head of a user and an occipital shelf support comprising a concave wall extending across the cradle. The cradle is secured on a base assembly which provides for movement of the cradle relative thereto to provide for both independent horizontal and vertical plane movements.Type: GrantFiled: November 17, 1986Date of Patent: April 12, 1988Assignee: 501 Tru-Trac Therapy Products Inc.Inventors: John W.

Patent number: 4283289Abstract: A leukocyte filter for blood which includes a housing defining a blood inlet and outlet at respective ends thereof, with the housing enclosing and carrying a tubular, non-woven fiber filter element, with one of the inlet and outlet communicating with the interior of the tubular filter element, and the other of the inlet and outlet communicating with the exterior of the tubular filter element. In the tubular filter element, essentially all of the fibers define diameters of 10 to 100 microns, and have other diameter restrictions described herein, with the fibers being bonded together to define a generally fixed, average interstitial spacing which is less at the inner surface of the tubular filter element than at the outer surface thereof. The air permeability of the filter per square foot is preferably from essentially 15 to 45 SCFM at one half inch of water.Type: GrantFiled: August 22, 1979Date of Patent: August 11, 1981Assignee: Baxter Travenol Laboratories, Inc.Inventors: Richard P. Meyst, Ronald M. Porten

Patent number: 4170056Abstract: A filter for blood and the like including a housing defining an inlet for fluids to be filtered, and an outlet for filtered fluid, plus a stack of filter pads of thermoplastic fibers positioned within the housing. According to one aspect of this invention, the stack of pads is joined together at their periphery by a heat seal to form an integral filter unit, while, typically, the stack is joined to the housing at such periphery by a second seal. In another aspect of this invention, the fluid inlet is positioned adjacent a first pad of the stack and the fluid outlet is adjacent a last pad of the stack, the diameter of the fibers of the last pad being smaller than the diameter of the fibers of the first pad, typically with the fiber diameter of intermediate pads generally decreasing from pad to pad in the direction of the last pad.Type: GrantFiled: June 6, 1977Date of Patent: October 9, 1979Assignee: Baxter Travenol Laboratories, Inc.Inventors: Richard P. Meyst, Ronald M. Porten
