Abstract: An improved tape tab system for use in disposable diapers in which one end of a first strip of tape is adhesively attached to a diaper. A second strip of tape with one adhesive surface is attached to the free end of the first strip. A releasable cover strip protects the adhesive surface of the second strip. Upon diapering, the cover strip is removed from the adhesive surface of the second strip and the composite strips are fastened to an opposite corner of the diaper, the adhesive surface of the second strip making the original contact and diaper closure. The diaper may be opened for inspection or adjustment by peeling the first strip from the attached second strip, and then reclosed by repositioning the tapes in an overlapping relationship.

Abstract: A plug of suitable dimension and material is removably inserted into the upper and/or lower punctal apertures of the eye to block the opening and the attendant canaliculus so as to thereby prevent the drainage of lacrimal fluid therethrough. The plug is comprised of tissue-tolerable, readily sterilizable material, such as polytetrafluorethylene (Teflon), or hydroxyethylmethacrylate (HEMA) hydrophilic polymer, methyl methacrylate, silicon, stainless steel or other inert metal material. The rod-like plug is formed with an oversized tip or barb portion that dilates and blockingly projects into the canaliculus, a smaller neck or waist portion upon which the punctum sphincter ring tightens, and a relatively larger, smooth head portion which rests upon the top of the punctal opening and prevents the plug from passing down into the canaliculus.

Abstract: A nasal insufflator for powdered medicaments comprises a tubular body having a longitudinal air passageway. One end of the body has an end suitable for insertion into a nostril, the other end is provided with a squeeze bulb by which a stream of air is driven through the passageway and into the nostril of a user. Wholly within the body and intermediate its ends is a chamber into which can be placed a capsule of powdered medicament. The device is characterised by having a piercing means, eg a needle, which is reciprocable along the axis of the passageway by having its non-operative end mounted upon the inner wall of the bulb. Longitudinal depression of the bulb drives the piercing end of the piercing means through the end walls of a capsule mounted in the chamber. Release of the bulb draws the piercing end back to its non-operative position, thus leaving the capsule pierced and ready to be emptied by transverse depression of the bulb.
