  • Patent number: 6506333
    Abstract: The present invention provides a method for fabricating a medical tubing. The method includes the steps of: (1) providing a material selected from the group consisting of ethylene homopolymers and ethylene copolymers, wherein the ethylene copolymers are obtained by copolymerizing ethylene with a comonomer selected from the group consisting of lower alkyl olefins, lower alkyl esters of a carboxylic acid and lower alkene esters of a carboxylic acid, the lower alkyl and lower alkene each have from 3-18 carbons, or blends thereof; (2) providing an extruder with an extrusion die; (3) extruding the material into a medical tubing; (4) providing a surface modifier solution; (5) preheating the surface modifier solution to a temperature within the range of 50-80° C.; and (6) applying the preheated solution onto the tubing at it exits the extrusion die when the tubing is in a molten state or a semi-molten state.

  • Publication number: 20020000733
    Abstract: An organizer liner is provided for use in a vehicle cargo compartment. The liner has a flexible bottom preferably conforming generally to the shape of the cargo compartment floor, and one or more of rear, side and front rigid elements, preferably at least some of which generally conform to walls of the cargo compartment. The rigid elements preferably include storage means such as cup holders, trays, bins, insulated coolers, soda or water/milk jug holders, storage boxes with or without lids, or storage wells. Optional partition dividers may be provided. The dividers may include at least one long reinforced divider between opposite walls of the liner, and optionally at least one short divider between the long divider and a wall of the liner, or between two long dividers.

  • Patent number: 6244154
    Abstract: A seating die for use in a reloading press containing a stationary head and a movable ram. The die is secured in the head of the press and the ram moves a cartridge containing a shell casing and an unseated bullet upwardly into the die. The die further includes an elongated housing having a passage passing axially therethrough. The lower part of the passage forms a guideway that opens into an expanded upper opening to form a shoulder therebetween. A guide having a body that is slidably mounted in the guideway and has a shank mounted at its proximal end that passes upwardly into the upper opening of the passage. A collar is mounted upon the shank that contains a radial flange that seats against the housing shoulder when the guide is in a home position. The distal end of the body section contains a bottom opening chamber for receiving the bullet as the ram moves upwardly whereupon the guide is moved upwardly into contact with an adjustable stop.

  • Patent number: 6187400
    Abstract: The present invention provides a method of using a medical tubing with a pump for administering measured amounts of a beneficial fluid over time to a patient comprising the steps of providing a tubing having a first layer selected from the group consisting of ethylene homopolymers and ethylene copolymers, wherein the copolymers of ethylene are an ethylene monomer copolymerized with at least one monomer selected from the group consisting of lower alkyl olefins, lower alkyl esters of a carboxylic acid, and lower alkene esters of a carboxylic acid, the lower alkyl and lower alkene having from 3 to 18 carbons, the tubing having been exposed to a sterilization dosage of radiation of from about 15 to about 45 kGys; and pumping fluid through the tubing with the pump.

  • Patent number: 6129876
    Abstract: The present invention provides a method for fabricating flexible medical tubings comprising the steps of providing a tubing of a polymer material, the tubing having a longitudinal axis and an initial diameter, orienting the tubing along the longitudinal axis of the tubing to reduce the diameter of the tubing to define a oriented diameter, and applying heat to the oriented tubing to heat set the tubing to maintain dimensional stability of the tubing over a temperature to which the tubing will normally be exposed.
