  • Patent number: 6114596
    Abstract: A breathable diaper, feminine hygiene, or like disposable sanitary product construction having a cloth-like outer surface and including a plurality of materials from the skin-facing side outwardly, a topsheet, a core, an optional barrier, and a backsheet. The topsheet is formed of liquid- and vapor-permeable hydrophilic material, and the core is formed of highly absorbent material disposed outwardly of the topsheet for absorbing liquid received through the topsheet. The core has an inner surface in liquid communication the said topsheet and an outer surface. The optional barrier is formed of a multilayer non-woven material which is hydrophobic and vapor-permeable for limiting the outward escape of liquid therethrough while enabling the outward escape of heat and water vapor therethrough. The barrier has a base disposed adjacent the core outer surface.

  • Patent number: 5013305
    Abstract: A device and method for preventing accidental needle sticks. A sleeve having an annular shaft is slidably connected to a needle. A cord is rigidly affixed to the hub of the needle at one end thereof and to a blocking member at the other end thereof is also slidably coupled to the sleeve. After the needle has been used and is being removed from the patient's body, the sleeve is slid along the needle shaft to cover the tip and pulls the blocking member into position over the sharp tip of the needle. This positively covers the sharp tip of a needle with a puncture-proof blocking member to prevent accidental needle sticks. In alternative embodiments, a resilient member is pressed to align a hole through which the needle is projecting with a hole in a puncture-proof member which is covering the sharp tip of the needle to permit the needle protective device to be slid down the shaft of the needle and the needle to be used. A recessed needle assembly to be used in tandem with a needle assembly, is also disclosed.
