Abstract: A device for delivering a substance into the skin of a patient includes a housing and a plurality of microneedles for penetrating the skin. The housing includes a bottom wall with a plurality of apertures for supplying the substance to the microneedles. The housing also includes a flexible top cover member enclosing a bladder containing the substance to be delivered. The bottom wall of the housing has at least one cannula facing the bladder. Pressing on the top cover member causes the cannula to puncture the bladder and deliver the substance to the microneedles for delivery to the patient. In one embodiment, the cannula is surrounded by a flexible member to prevent piercing of the bladder until sufficient pressure is applied to the cover member to depress the flexible member.

Abstract: A lancet assembly includes an injection molded housing with a metal stylet mounted therein and a cap or shield. The stylet is held in position by adhesive and a plurality of supports that retain a centrally located hub within a lower portion of the housing. An improved cap is provided for mounting over the stylet on the lower portion of the housing to shield the stylet prior to use. The cap also includes an octagonal flange at its lower end to ease removal of the cap from the housing and to provide a flat octagonal surface for independent standing during reshielding.

Abstract: In a color-slide duplicator having a housing containing a light source which illuminates an opening in a housing wall, and a support for a camera above the housing for photographic reproduction of a slide to be duplicated; an assembly for supporting the slide comprises a carrier plate releasably and adjustably secured by magnets to the housing wall so as to span the illuminated opening which registers, at least in part, with an aperture in the carrier plate, and first and second parallel guide bars having undercut, beveled edges facing toward each other and being arranged on the carrier plate at opposite sides of the aperture in the latter, with one of the guide bars being movable laterally and resiliently urged in the direction toward the other guide bar, such guide bars being included in a quick-release mechanism by which the slide to be duplicated is positioned and held against the carrier plate over the aperture therein.
