  • Patent number: 6494872
    Abstract: The present invention is directed to provide a diaper having a pocket structure which includes a breakage-resistant hydrophobic topsheet and an apertured portion of proper size which is surrounded by a strengthened inner periphery and provides an improved leakage protection effect. The present invention is further directed to a method of manufacturing such diaper which enables economical and simplified process operation. A diaper is,provided wherein an absorbent body is interposed between a liquid impermeable backsheet and an apertured hydrophobic topsheet to form side, front and rear end portions of the diaper. The hydrophobic topsheet includes two separate sheets each having alternating concave portion and convex portions defined by a wavy side edge. The two sheets are arranged to face to each,other so that the convex portions thereof partially overlay each other at front and rear end portions of the diaper to form pocket portions.

  • Patent number: 6213992
    Abstract: A disposable garment, such as a diaper, having a liner, an absorbent core and a liquid impervious bottom sheet. Coextensive openings are formed in the liner, bottom sheet and core, and a transparent layer of material overlays the openings to form a window through the openings into the diaper. An opaque, pliable cover is preferably attached to an exterior surface of the bottom sheet so as to overlie the transparent window. The cover includes a layer of adhesive material to enable the cover to be releasably affixed to the window. The cover preferably further includes a tab, the tab and adhesive cooperating to enable the cover to be selectively pulled back to allow for viewing through the transparent layer into the diaper, and then replaced over the opening to conceal the contents of the diaper.

  • Patent number: 5611879
    Abstract: An absorbent article, such as a sanitary napkin, a diaper, training pants, an incontinent garment or a bedpad is disclosed for absorption of human exudate. The absorbent article includes an absorbent having a homogeneous composition with an essentially constant density in the x-y plane. The absorbent has at least two distinct portions which are integrally joined together by a junction line and each portion has a thickness different from an adjacent portion. The absorbent is folded on the junction line to obtain a variable density along the z axis. The folded absorbent also has a uniform capillary size in the x-y plane and a variable capillary size in the z direction. The absorbent article further includes a liquid-permeable cover which is positioned adjacent to at least one surface of the absorbent. A method of forming the article is also disclosed.

  • Patent number: 5112292
    Abstract: A temporary circulatory assist pump is disclosed for implantation in the heart of a patient through the femoral artery. The pump is driven by a flexible drive shaft extending through a catheter and being connected to a power source outside the body of the patient. The pump utilizes a helical-shaped foil impeller to pump blood at a rate of approximately three to four liters per minute through the circulatory system of the patient.

  • Patent number: 4773410
    Abstract: A method and an apparatus are described which are useful for respiratory tract therapy. The method comprises contact of mucous membranes with vapor-phase water in the substantial absence of nucleating water-vapor condensation particulate, and includes the use of a heated delivery tube, unheated nasal cannula, for the delivery of a nasal cannula vapor/gas stream to a nasal passageway at delivery rates in excess of 8 liters per minute at dew point temperatures equal to or less than dry bulb temperatures and heating of a delivery tube vapor-gas stream to a temperature sufficiently greater than the canula nare dew point use temperature in order to cause a readily observable cannula condensation film to form near the exit use ports thereby signaling that the appropriate cannula delivery stream dew point-dry bulb temperature differential exists which insures that the dry bulb nare exit temperature is equal to or greater than the nare dew point use temperature.
