Abstract: A device for transdermal administration of a drug comprises a reservoir containing the drug and a supporting strap, or band, which substantially surrounds a limb of the patient and holds the reservoir in position on a limb of the patient. The reservoir is generally non permeable to the drug, but has a membrane, or plate, of defined surface area through which said drug can pass. In use, this membrane or plate is held against the patient's skin to allow the drug to be absorbed. The device further includes cooperating locking mechanisms for detachably securing the reservoir on the strap or band whereby the supply of drug can be replenished by removing the spent reservoir and inserting a fresh one containing a new supply of the drug.

Abstract: A formulation chamber is disclosed comprising a wall surrounding a lumen containing a device for delivering a beneficial agent. The chamber has an inlet for admitting a fluid into the chamber and an outlet for letting an agent formulation leave the chamber. The chamber is adapted for use in an intravenous delivery system for delivering an agent formulation to a patient.

Abstract: A disposable product, such as a diaper, sanitary napkin or underpad, provided with a water impervious lower layer, an absorbent pad and a top sheet. The top sheet contains 0.1 to 0.6% by weight of a surfactant. The surfactant may be applied by spraying, printing, roller coating, etc., on the entire surface or, preferably, in limited areas such as in the central areas of the top sheet, or pay be line or spot printed thereon to improve fluid penetration, while retaining optimum fluid wetback and fluid retention characteristics. The top sheet is a hydrophobic sheet of excellent fluid penetration but resists fluid wetback.

Abstract: Sustained release dosage forms that provide transdermal delivery of drugs utilizing the skin as the rate controlling membrane for the drugs. Methods for producing the dosage forms are also disclosed. The dosage forms are laminates produced by heating a laminate to a glass transition temperature of an outer removable layer of the laminate. While maintaining the laminate at the glass transition temperature, a vacuum is applied to draw the laminate into a suitable shape for a drug reservoir. An aqueous solvent is added to the reservoir and a semipermeable barrier layer is placed over the aqueous solvent in the reservoir. A pharmaceutically active drug is contained in the aqueous reservoir and this drug moves transdermally to provide the active ingredient to the patient.

Abstract: A device for the slow release of chemicals into the body of an animal when the device is positioned in a body cavity of that animal, is formed as a flexible core member (1) from polypropylene, polyethylene or other polymer in a shape having a plurality of lobes (4,8) one (4) of which is longer than other shorter lobes (8) and the shorter lobes (8) being foldable for insertion and removal purposes. The core (1) has a solid (3) secured to the surface thereof or forming a part of the surface thereof which solid of silicone rubber or ethylene vinyl acetate or other suitable polymer is impregnated with one or more chemicals which in use are leached therefrom by body fluids. A withdrawal ligament (14) is attached to the free end of the longer lobe.

Abstract: An absorbent product is provided having a first fibrous layer in the form of a nonwoven web and a second layer which is discrete from the first layer but united to the first layer. The second layer has a higher capillary pressure than the first layer to provide preferential attraction and wicking of liquid. The layers are corrugated and stabilized to retain the transverse folds when wet.

Abstract: The invention relates to a leak resistant disposable diaper or incontinent brief particularly suitable for adult wear. The garment is from about two to three times as long as it is wide so that the sides of the wearer are not covered. Each end of the garment has a relatively long flap formed by extensions of the envelope retaining the pad of absorbent material. The absorbent pad itself is trimmed generally in the form of an hourglass. However, the cutout side portions are located forward of the transverse centerline of the pad. Also, the forward edge of the cutouts does not expand as rapidly to full width as does the back edge to allow a better fit in the groin area. Elastic strips are located adjacent to the edges of the pad and run the full length of the product. Relatively long attachment straps are anchored to the back flap and form the means of holding the garment on the wearer.

Abstract: Hemostatic-adhesive, collagen dressings in the form of dry-laid, non-woven, self-supporting webs of collagen fibers and methods for preparing those webs are disclosed. The webs are formed from a mass of hemostatic-adhesive, collagen fibers having a moisture content of from about 7% to about 15% by weight, and retain the hemostatic-adhesive properties of the mass of collagen fibers.

Abstract: This invention relates to a medicated device for insertion into the uterus or cervix comprising a T-shaped platform and a drug release attachment thereon, the platform having a vertical stem portion with a rounded knob portion at the top thereof and two flat flexible downwardly slanting arms extending from the knob, the arms tapering to a lesser dimension at the end from the knob to the end of the arms and the arms having a downward bend of about 45.degree.-110.degree. proximate the end of each arm.

Abstract: A delivery system is disclosed comprising a wall surrounding a lumen containing a plurality of osmotic delivery devices. The wall is formed of an environment sensitive material that releases the tiny osmotic devices into the environment. The osmotic devices comprise a semipermeable wall surrounding a compartment containing drug. A passageway through the semipermeable wall releases drug from the device to the environment.

Abstract: A sanitary napkin having an absorbent batt containing a thermoplastic material is provided. The absorbent batt is folded on itself at least on each longitudinal axis with the fold being maintained by fusing areas of the adjacent layers over the batt near the folded edge.Also contemplated are multiple layers of absorbent formed by folding with the folds being maintained by additional fused areas.

Abstract: A pair of sanitary napkins is provided each with an absorbent layer and a fluid permeable baffle with adhesive for garment attachment attached thereto. These napkins are put in abutting relationship with a release liner coated on both sides positioned between the adhesive coated bottom surfaces of the respective napkins.

Abstract: An osmotic device is disclosed for delivering a beneficial agent. The device comprises a wall surrounding a compartment containing an agent, a passageway in the wall connecting the exterior of the device with the compartment, and (a) an agent in the wall or (b) an agent carried on the wall in the wall. The device delivers the agent from the compartment and the wall.

Abstract: This invention relates to a tampon tube in which the finger grip area has been cut through and compressed to provide an area of reduced diameter.

Abstract: A laminated structure adapted to be gathered for improved fit about a portion of the human body, said laminated structure comprising an elastic member disposed between first and second substrates of flexible gatherable material, said elastic member including a plurality of interconnected elastic elements defining apertures therebetween, and the first and second substrates of said laminated structure being secured together through at least some of said apertures.

Abstract: An outer tampon tube is provided with a finger gripping section on one end formed by a series of spaced circumferentially disposed slits, each slit being equidistant from the tube ends and indentations extending radially from the slits formed by crease lines extending from the bottom of the tube to the slits.

Abstract: A pressure sensitive adhesive membrane and its cooperating, protective, underlying coated release paper are provided with adhesive means and the membrane and paper layer are then formed into and maintained as a substantially cylindrical, rolled configuration, creating a unique easily handled, readily employable membrane dispensing assembly. In the preferred embodiment, the adhesive means is applied to the non-release coated surface of the paper layer, thereby assuring maintenance of the rolled configuration while enhancing the deployability and the efficacy of the membrane.
