Title: Safety needle container
Inventor: HOLLISTER WILLIAM H
IPC: A61M5/32
Filed: 1991-05-16
Granted: 2002-12-17
Abstract: A universal safety adapter which is usable with different types of needles and syringes has integral first and second sections and a housing flexibly connected to one of the sections. In the case of the first section being adaptable to be mated with the hub of a needle assembly, the housing is flexibly connected thereto by way of a living hinge. The needle assembly is threadedly mated with an internally threaded annular collar surrounding a protrusion which is to be coupled to the hub of the needle assembly. The second section of the safety adapter, in a first embodiment, includes a female luer that is adaptable to be mated with different types of syringes, such as a luer slip syringe or a luer lock syringe. Once the needle assembly has been threadedly mated to the first section of the safety adapter, to ensure that the cannula of the needle assembly is not exposed so as to preclude accidental pricking by the needle, the housing is pivoted to a position whereby it completely envelops the cannula. At least one integral retainer mechanism in the housing prevents relative movement between the cannula and the housing once the housing has been pivoted to envelop the cannula. The dead space volume at the junction where the needle is connected to the syringe can be substantially reduced by a second embodiment of the safety adapter of the present invention which includes a male extension within the female luer.

Abstract: A method of affixing a plurality of tubes having oval ends into a plurality of corresponding oval openings in the header wall of a heat exchanger in which the wall has an inner, liquid-facing side and an outer, air-facing side. The oval ends of the tubes are sized such that the minor diameter of the tube ends is greater than the minor diameter of the header openings and the major diameter of the tube ends is less than the major diameter of the header openings, the circumference of the tube ends and the header openings being substantially equal. The tube ends are inserted into corresponding openings in the header wall whereupon the minor diameter of the tube ends is reduced and the major diameter of the tube ends is increased to create a substantially fully contacting fit around the circumference with said header openings. Ends of the tubes are welded to corresponding collar openings in the header wall, such that the tubes extend toward the air-facing side of the wall, to form a plurality of welded tube-to-header joints. Flux is applied by spraying or the like to the air-facing side of the tube-to-header joints. Thereafter, a lead/tin or other molten solder is applied to the liquid-facing side of the tube-to-header joint by dipping or wave solder techniques and flowed into any voids in the welded joints to substantially seal the joints against leakage of liquid.      Only those joints having potential liquid leaking voids receive the solder - sound, liquid-tight welded joints axe not solder sealed.

Granted: 1995-09-05
Abstract: A computer is used to calculate the location of a target, customize the target to conform to the lens, frame and patient characteristics  of  each individual  job and automatically compensate for parallax in the apparatus.  A convenient open work surface is provided for the operator to position the lens blank on a non-skid surface.   The block is applied at a constant limited force in a manual or automatic mode of operation on either frame or optical center.  The offsets for positioning the lens blank are calculated within the blocker based upon frame and patient data.  This data can be input directly or can be downloaded from a database.  These offsets determine the location of the target relative to the optical markings on the lens blank.  The amount the target is offset is scaled automatically to compensate for the fact that the lens blanks  are on  a work  surface  above  the  electronic display.  A customized target is displayed.  The target is scaled to match the segment widths for multi-focal lenses, and provides a centered target location with multiple horizontal lines for single vision lenses, including progressive lenses. Scaling  of  the  width  eliminates operator  judgement  to "eyeball" the center.  The multiple horizontal lines provide an additional aid in aligning progressive lenses where the distance from the "mounting cross" to the horizontal line on the lens blank varies by manufacturer.  The frame shape may also be displayed to provide a sense of fit.
