Abstract: A process for preparing sterilized hot melt adhesive bonded articles is disclosed comprising applying to one surface of an adhesive, such as a hot melt adhesive film, a blend of polypropylene, a tackifying hydrocarbon resin, and a diluent, pressing the surfaces onto the adhesive while it is molten, and subsequently thermally sterilizing the bonded article.
Abstract: An appliance for supporting and/or protecting body portions comprises a pair of substantially rigid sheet-like members adapted to engage against predetermined spaced portions of the body of a wearer. The sheet-like members are coupled together at one end by means of a relatively large expanse of elastic material and are detachably connected together at the other end also by means of elastic material, the resulting structure encircling a body portion. This construction permits substantial contraction and expansion of the encircled body portion without substantially restraining the encircled body portion from expansion.
Abstract: A disposable diaper having an absorbent pad, a fluid impervious backing sheet defining a back surface of the diaper, a front surface, and a plurality of longitudinally extending folds defining a box-pleat configuration of the diaper. An end flap of the box-pleat diaper is folded over the front surface of the diaper, and means is provided for retaining a least a portion of the front surface of the flap against the underlying front surface of the box-pleat diaper.
Abstract: A rechargeable infusate pump for implantation in the human body can be refilled periodically by injection through an inlet septum under the skin. A conduit from the pump outlet conducts fluid to an infusion site in the body. The needle penetrating the septum protrudes into an antechamber and discharges fluid and any foreign matter is trapped in the antechamber so that it cannot enter the pump chamber and possibly clog the pump outlet. This foreign material is removed by injecting a needle into the antechamber and drawing a vacuum to suck out the debris.The pump also has a special ring-like outlet filter in the fluid stream between the pump chamber and its outlet to provide a maximum amount of filter area in a minimum amount of space and the pump outlet includes a special flow controller which is able to very accurately meter the infusate to the selected body site.
