  • Patent number: 5320603
    Abstract: A hypodermic syringe has a tubular body extending along and centered on an axis and having at an axial front end a small-diameter collar formed with a front radially outwardly open seat and, axially spaced backward therefrom, a rear radially outwardly open seat. An end piece provided with a deformable plug fittable sealingly in the collar is adapted to receive a needle. Mounting fingers extending axially back from the end piece have rear ends that engage in a front position of the end piece in the front seat and in a rear position of the end piece in the rear seat. The fingers are of such an axial length that the plug is fitted snugly into the collar in the rear position but is not snugly fitted in the collar in the front position. When the end piece is in the front position a medicament in the body can be lyophilized and when in the rear position the syringe is plugged.

  • Patent number: 5185985
    Abstract: An apparatus for handling a plurality of elongated tubular bodies each having a small-diameter neck and a large-diameter shaft has a pair of support plates formed with respective similar arrays of throughgoing openings generally complementary to the section of the shafts of the bodies and spacers supporting the plates parallel to and spaced from each other with the openings arranged pairwise with one opening of each plate aligned along a respective axis with a respective opening of the other plate so that the bodies can be held therein. A stop plate parallel to and spaced from the support plates is formed with stop openings in an array like the openings of the support plates.

  • Patent number: 5139490
    Abstract: A hypodermic-syringe assembly comprises a hard tubular body centered on an axis and having an axial front end formed with a radially inwardly projecting annular ridge and an axial rear end, a piston axially slidable in the body and normally adjacent the rear end, and a soft plug fitted in the front end in tight engagement with the ridge. The plug is formed with an axially rearwardly open blind passage having a front floor, and a front face defining with the passage floor a relatively thin membrane. Thus a needle can be poked through the membrane.

  • Patent number: 5135496
    Abstract: A hypodermic syringe assembly has a hollow body having a neck centered on an axis, an elastomeric plug fitted in the neck and having an end projecting axially forward from the neck, a stiffening sleeve fitted over the plug and neck and having a collar fitting around the projecting plug end and itself projecting axially therepast, an elastomeric stopper fitted into the collar, and a protective cap fitted over the plug, sleeve, and stopper. A destructible connection between the cap and the sleeve retains the cap in place on the body over the plug, sleeve, and stopper. This cap is therefore only removable from the body by destruction of the connection. The protective cap is basically cylindrical and centered on the axis and has a front end wall generally transverse of the axis and an opposite rear end edge and the destructible connection extends annularly between the end edge of the cap and the sleeve.

  • Patent number: 5069670
    Abstract: A hypodermic syringe has a generally cylindrically tubular body extending along an axis and having an axial front end formed with a radially outwardly projecting annular bead, a piston axially displaceable in the body, a plug having a rearwardly directed flange fitting complementarily over the front end of the body at the bead and forwardly blocking the body, and a flat soft seal ring compressed axially between the plug and the front end of the body. The body has a rear end provided with a finger-rest crosspiece and the piston is provided with a plunger projecting axially out the rear end past the crosspiece.

  • Patent number: 4781701
    Abstract: The syringe has a needle-attachment piece which forms a connection neck for affixing the syringe needle and which is held at the cylinder nozzle of the syringe cylinder by a connection piece notched in at the cylinder nozzle. The connection piece is provided with a collar which externally surrounds the connection neck sealing it tightly and mechanically stiffening the same, so that the syringe needle can be held in a stable manner, even when the needle-attachment piece is made of a soft elastic material, in order to provide a perfect seal.

  • Patent number: 4774772
    Abstract: The apparatus for handling a finished syringe bodies comprises a planar supporting plate and a mounting plate provided with foot members attached with the supporting plate substantially parallel thereto by a plurality of spacing pieces. Both supporting plate and mounting plate have a plurality of receiving openings for the injection molding devices positioned pairwise coaxial to each other and a retaining plate is provided with holes coaxial to the receiving openings and connected detachably to the supporting plate on the side of the supporting plate facing away from the mounting plate. The boundaries of the holes in the retaining plate form an axial contacting surface for the injection molding devices placed in the receiving openings.
