  • Patent number: 5120302
    Abstract: A blood container comprises a generally cylindrically shaped outer housing (11) having an upper portion, a lower portion and a bottom portion which declines downwardly to an outlet 3. A generally cylindrically shaped filter 2 is enclosed concentrically within the upper portion of outer housing for receiving blood at the top thereof and discharging filtered blood at the wall and base of the filter. A generally cylindrically shaped inner housing (4) extending from the base of the filter to the bottom portion of the outer housing. The container particularly includes means (5, 9, 9a, 9b, 11) for directing and restricting the flow of blood from the base of the filter for a gradual and smooth descent to the outlet which avoids the creation of bubbles and avoids any blood cell damage.

  • Patent number: 4661300
    Abstract: A method and apparatus for tipping one end of an I.V. catheter includes the method steps for use of the apparatus including mounting a catheter to be tipped onto a mandrel supported on a carriage; a die having an interior molding surface, at least one portion of which is tapered according to the tip desired on the catheter, is heated; the carriage is moved along guide bars to the die such that the catheter carrying mandrel moves toward the interior molding surface to define a space, when the carriage is halted the catheter carrying mandrel is biased toward the die space with only sufficient force to cause the heated catheter to flow into the die space and as the catheter melts and flows, the mandrel engages the die thereby defining the edge of the catheter, after which the die and catheter therein are cooled; the carriage is then reversed along the guide bars such that the catheter and mandrel are withdrawn from the die, and the catheter is removed from the mandrel.
