Abstract: The invention is an improved attachment strap for a large diaper or adult incontinent pad. It consists of an accordion pleated length of material, preferably a nonwoven fabric, with one end permanently attached to the diaper body. The final pleat at the opposite end is terminated by a length of peelable pressure sensitive tape which overhangs each edge of the pleat. The medially oriented overhang is relatively narrow while the laterally oriented overhang, which ultimately serves as an attachment tab, is relatively wider. When in stored position, the two overhanging portions hold the folded tape compactly against the back face of the diaper where they do not interfere with manufacturing or packaging operations. The peelable attachment tape has an adhesive coating that is relatively high in shear strength but modest in peel strength. These characteristics are chosen so that the tape can be peeled off without tearing the diaper backing sheet.
Abstract: A gastrostomy-jejunal feeding tube comprises a gastrostomy tube having an enlarged resiliently, collapsible retainer element on the distal end thereof and a jejunal feeding tube which is removably received in the gastrostomy tube in a manner which allows fluids to pass through the gastrostomy tube despite the presence of the jejunal feeding tube therein. The gastrostomy-jejunal feeding tube is adapted to be installed in a patient so that the gastrostomy tube extends through the stomach wall, fascia and skin for draining fluids from the stomach and so that the jejunal feeding tube extends into the jejunum area of the intestines for feeding and medicating the patient. Since the jejunal feeding tube is removable from the gastrostomy tube it can be replaced without surgery, and since the retainer element is resiliently collapsible, it can be pulled outwardly through the stomach wall to allow the gastrostomy tube to be removed from the patient without surgery.
