Abstract: The present invention provides a syringe assembly for a medication pump, such as an insulin pump, or the like that includes a pair of protruding structures at one end that mate with the typical pair of opposed recesses or other notch structures of the syringe assembly mating portion of the pump, without the use of a cap structure and needle member, and that may be manufactured primarily from a relatively inexpensive plastic material or the like, while still providing the medication supply back-pressure required to be adequately sensed by the pump electronics, such that the pump accepts the syringe assembly and is “primed” for proper operation.

Abstract: The invention relates to a device for mounting a needle guard onto a syringe body that is provided with a needle. The device includes a retaining device for retaining the syringe body, a needle guard receptacle for receiving the needle guard, a compressed air system for providing compressed air, a first displacement device for displacing the needle guard receptacle in a vertical direction, and a rotation device for at least partially rotating the needle guard receptacle. The needle guard receptacle is disposed beneath the retaining device while the compressed air is fed to the needle guard receptacle such that the needle guard is suspended on an air cushion in a floating manner. The needle guard receptacle can be displaced in a vertical direction by the first displacement device. The invention further relates to a method for mounting the needle guard onto the syringe body.

Abstract: The present invention is directed to a novel process for inserting a cannula, such as a hypodermic needle, into a hub member by roughening a first portion of the cannula while leaving a second portion substantially smooth such that the first portion forms an interference fit and the second portion a line-to-line fit with the hub bore. In the absence of an adhesive, the second portion is passed through the hub bore followed by the first portion. The first portion is forced into the hub bore to provide an adhesive-free interference fit that is capable of resisting puncturing forces during normal use.

Abstract: A sharp cutting object disposal device provided with means for automatic unscrewing of venopuncture needles and the like, consisting of a tube to which a pair of motors or a gear wheel are fixed, the wheel which, actuated by a geared part that upon sliding on the gear wheel, will cause the rotation of the latter and in turn, this gear wheel will move several gears which will make two cylindrical and solid contacts turn, carrying out the disposal of the needle by means of friction plus the passing of electric current, provided with a conduit inside for exhaust of gases produced by melting the needle, without needing ventilators or any other forced air system, in addition to having another tube for separating the needle from the “screw-on” type syringe during the same needle disposal operation, the inside of the drawer having a housing recipient for the needle wastes, and another recipient incorporated inside the container for housing the plastic needleless syringes or non-sharp hospital wastes, and inside this

Abstract: Apparatus for assembling injection devices includes first and second pairs of shafts spaced apart from one another and defining axes extending parallel to a first inclined axis. The shafts include grooves extending helically between ends of the shafts, the helical grooves together defining passages extending vertically between the shafts. The shafts are rotated about their axes such that the passages move between first and second ends of the shafts. Syringes are introduced into successive passages to carry the syringes downwardly along the inclined axis between the first and second ends of the shafts while maintaining the syringes oriented vertically and spaced apart. Guards are carried along a horizontal axis that converges with the inclined axis at a convergence region. The guards are spaced apart and suspended vertically below corresponding syringes such that the syringes are received in successive guards at the convergence region.

Abstract: A first fixture of a transportable fixture apparatus incorporates a substantially porous first region adapted to receive one or more porous and/or non-porous first material layers, such as fuel cell layers, and to facilitate formation of a vacuum between the first fixture and the first material layers. A second fixture incorporates a substantially porous second region adapted to receive one or more porous and/or non-porous second material layers and to facilitate formation of a vacuum between the second fixture and the second material layers. A stop arrangement protrudes from one or both of the first and second fixtures, and is situated peripheral to the first and second material layers when the first and second fixtures are brought into contact. The stop arrangement defines a cavity adapted to effect compression of the first and second material layers when the first and second fixtures are brought into contact.

Abstract: A needle-stick safety syringe includes an inner tubular body, plunger, and needle extending from a distal end of said inner tubular body, an outer tubular housing concentrically and slidingly surrounding at least a portion of the inner tubular body and biased apart from the inner tubular body. A recess is defined within an interior wall surface of the outer tubular housing, and a latch attached to a distal end of the inner tubular body. The latch includes a ring-shaped collar attached to the distal end of the inner tubular body and includes a cantilevered push-stop. A portion of the cantilevered push-stop is sized to fit within the recess when the latch is sufficiently disposed within the outer tubular housing.

Abstract: A needle removal/destruction apparatus for pulling a metal needle free from a plastic hypodermic syringe, while also deforming the metal needle to prevent reuse thereof. The apparatus includes a container having a rotatable needle removing fixture mounted therein. A metal needle hypodermic syringe is inserted within the rotatable needle removing fixture, which is thereafter rotated to pull the needle free of the needle hub while also permanently deforming the needle to prevent subsequent reuse thereof.
