  • Patent number: 10610647
    Abstract: The invention provides a syringe assembly comprising a syringe barrel having an inside surface defining a chamber, an open proximal end, and a distal end having an opening therethrough. An elongated plunger rod extends between a first end and a second end, with a cap or guard disposed on the first end of the plunger rod. A plunger head extends within the chamber of the syringe barrel, and is adapted for slidable movement within the syringe barrel between the proximal end and the distal end, with the second end of the plunger rod connected with the plunger head through a pivotable connection. The plunger rod is adapted to pivot with respect to the plunger head between a first position in which the guard is adjacent the distal end of the syringe barrel and a second position in which the plunger rod is in general axial alignment with the syringe barrel, and is further adapted for axial movement so as to cause sliding movement of the plunger head through the syringe barrel to expel contents thereof.

  • Patent number: 10569030
    Abstract: A piston for use in an injector comprising a cylinder having a longitudinal axis and an inner wall, which piston has a deformable sealing element with a convex surface, which deformable sealing element when the piston is inserted in the cylinder abuts the inner wall of the cylinder at an abutting interface and seals an annular gap between the piston and the inner wall of the cylinder. The abutting interface and the deformable sealing element have axial dimensions parallel with the longitudinal axis. The ratio between the axial dimension of the abutting interface and the axial dimension of the deformable sealing element is in the range between 0.01 and 0.2. In another aspect, an injector includes the piston and is used in a disposable syringe of the piston. The piston can prevent refilling of a syringe.

  • Patent number: 7635348
    Abstract: Containers for automatic injectors and automatic injectors adapted for those containers are disclosed. The containers include structures adapted to retain and, optionally, cripple the needle of the automatic injector when the automatic injector is inserted into the container after use. Depending on the embodiment, an indicator may be included, either as part of the container or as part of the automatic injector, to indicate whether or not the automatic injector has been used. If the indicator is provided as a part of the automatic injector, a corresponding portion of the container may be formed of a light permeable material. The container may also include features, such as an eyelet over the closed end, designed to cushion the automatic injector. Cushioning and shock absorbing features may also be provided inside the container. A clip is also disclosed. The clip is designed to attach two or more containers together.

  • Patent number: 7449009
    Abstract: An injection channel is produced in human or animal tissue by means of a pre-injection device for incorporating a medium which is to be injected. Said pre-injection device comprises a chamber which is used to receive a pre-injection medium, a nozzle which is provided for attachment to the skin and a pressure generating device which acts on the chamber in order to generate a high-pressure jet from the pre-injection medium exiting from the nozzle. Said type of needle-free pre-injection device is serially connected to a main injection device.

  • Patent number: 7252651
    Abstract: An injection device is provided. The device includes a housing having a first end defining a first opening. A plunger is received within the first opening of the housing to move between first and second positions. A cartridge is disposed in the housing and has an interior serving as a reservoir for a drug. A delivery needle is disposed within the housing and is in fluid communication with the reservoir via an interruptible fluid channel. A locking mechanism is disposed in the housing. In the first position of the plunger the delivery needle is enclosed by the plunger and in the second position of the plunger the delivery needle is placed in an injection position and the plunger activates the locking mechanism whereby when the plunger returns to the first position the locking mechanism prevents the needle from being placed in the injection position.

  • Publication number: 20010056263
    Abstract: A prefillable delivery device for administering intradermal injections includes a prefillable container adapted to store a substance. The substance is expelled through a needle cannula having a forward tip adapted to administer the intradermal injection. A limiter surrounds the needle cannula having a generally flat skin engaging surface extending in a plane generally perpendicular to the needle cannula. An insert is centrally located within the skin engaging surface and is piercable by the forward tip. A sleeve with a first end and a second end surrounds the prefillable container. The limiter is slidably inserted through the first end and the second end is affixed to a depressable plunger for expelling the substance from the container. The limiter is movable between a first position and a second position thereby exposing the forward tip and is selectively movable between a third position and a fourth position thereby concealing the forward tip.

  • Publication number: 20010041867
    Abstract: A single-use syringe has a barrel which can constitute a one-piece extrusion, and a shank which is reciprocably guided in the barrel and the distal end of which carries a plunger movable in the barrel toward and away from the needle-carrying front end portion of the barrel. The coupling between the plunger and the shank includes a set of circumferentially spaced-apart breakable spokes which can be of one piece with the distal end of the shank as well as with the plunger. The spokes break not later than when the shank completes a forward stroke during which the plunger expels a flowable substance, such as a medicine, from a chamber located in the barrel between the needle-carrying front end portion and the plunger. The plunger, the spokes and the shank can constitute a one-piece extrusion.

  • Patent number: 5709659
    Abstract: The present invention is directed to a drug containing non-reusable syringe having a hollow plunger rod provided with a rupture line for permanently detaching its rear part which can be engaged with the needle holder to perform a radial motion that breaks the needle which thereafter is received by a cavity in the rear part of the detached plunger rod. The rear part of the plunger rod can also be attached to the needle holder to protect the user from accidental needle sticks.

  • Patent number: 5380296
    Abstract: A self-packaging safety syringe set (2) uses a unitary molded set of enclosure units (8, 104) sized for housing conventional cartridge-needle units (12) therein. The set of enclosure units are connected to one another by frangible connections (64, 66; 130, 138). The cartridge-needle unit has a hollow barrel (14) with a needle assembly (24) mounted to one end and a piston (16) mounted therein. Each enclosure unit includes a body section (38, 106), a stem section (44, 108) frangibly connected to one end of the body section, and an end cap (52, 110) connected to the other end of the body section. The frangible connection (48, 118) is broken to remove the stem section to expose the needle (26) for use. The removed stem section is used to drive the piston within the barrel. After use, the barrel is pulled back through the body section so that the needle is completely housed within the body section.

  • Patent number: 4834717
    Abstract: A disposable, sterilizable syringe for injecting a fluid medication from a pre-filled cartridge or ampule to a targeted tissue area. The syringe includes an elongated, detachable sheath which performs the functions of both a protective sheathing for surrounding a needle cannula at the distal end of the syringe cylinder and the stem of a piston assembly at the proximal end of the cylinder for expulsing medication from the cartridge. An axially extending guide slot having distally and proximally oriented locking detents is formed through a side of the syringe cylinder. A needle position control button is adapted to ride through the guide slot to cause a needle carrying hub, to which the control button is integrally connected and from which the needle cannula projects, to correspondingly move through the cylinder.
