Abstract:
Medical needle shield apparatus for covering a needle after use. In embodiments of this invention a shield with two or more segments hingedly connected to each other is movable from a retracted position where the needle is exposed, to an extended position where the shield extends beyond the end of the needle. The needle is affixed in a hub of a medical needle device, and the shield is articulated to the hub. At least one of the two or more segments has an open orifice through which the needle passes to form an axis of intersection about the needle. The shield includes a channel for covering the needle when the shield is linearly extended. One or more locks associated with one or more of the segments secures one or more of the segments relative to the shield in the extended position. A latch is also disposed on the distal segment for securing the distal segment relative to the shield when in the extended position. The number of hingedly connected segments depends upon the needle length and device length required to extend the shield beyond the distal end of the needle.

Abstract:
The present invention provides a container and method for storing a solution containing a labile species comprising storing said solution in a flexible, optically transparent container comprised of an ethylene vinyl alcohol copolymer having an oxygen permeability of less than 0.2 cc/100 in2/24 hrs.
Abstract:
A vial filling system for a needle-less injector, the system including an adaptor. The adaptor has a housing including a top and a side wall extending downwardly from the top. A recess is disposed in the side wall of the adaptor for receiving a vial. The vial has an inner cavity for receiving a liquid formulation. An inlet opening is located in the top of the adaptor, wherein when the vial is inserted into the recess the inlet opening is aligned with a nozzle of the vial. A needle extends from the top of the housing and in communication with the inlet opening. The needle is constructed and arranged to pierce a container of liquid formulation. A plunger is movably disposed within the cavity of vial for drawing the liquid formulation from the container into the cavity of the vial.
Abstract:
An apparatus for introducing a liquid into a pharmaceutical container such as a vial, having a puncturable closure, comprising a hollow needle with at least one orifice through the needle side wall being oriented to direct liquid flowing along the bore in a direction having a component parallel to the flow direction, with a vent groove in its outer surface. A preferred construction of needle and a process for making it are disclosed.
Abstract:
A fluid transfer device comprising a hollow piercing element having a first end for receiving a standard syringe nose or other similar medical device and a second end having a tapered tip for accessing fluid inside a medication container is disclosed. In a preferred embodiment, the device has a disk-shaped stop for limiting entry of the piercing element into the vial. Preferably, the piercing element includes outwardly extending barbs which allow the device to be inserted into a vial but which prevent the device from being removed from the vial after insertion. After the syringe is disengaged from the device, the device and spent medication vial may be discarded as a unit. Alternatively, the device can remain attached to the vial, and a new syringe can be used to withdraw additional fluid from the vial when desired. In an alternate embodiment, a reusable, resealable valve is connected to the first end of the piercing element, which valve allows multiple syringes to be used with the piercing element. Various adaptors for using the device with intravascular (IV) lines and drip-bags are also disclosed.
Abstract:
The present invention provides for an assembly for transferring a fluid between a vessel having a body with an open end and a slidable piston positioned within the body and a vial having a penetrable seal. The assembly includes a housing having first and second open ends, and a bore extending between the first and second open ends. The housing is removably connectable to the piston. The assembly also includes a conduit having first and second ends and first and second apertures adjacent to the first and second ends, respectively. The conduit is longitudinally slidable within the bore between a retracted position in which the first aperture is The present invention provides for an assembly for transferring a fluid between a vessel having a body with an open end and a slidable piston positioned within the body and a vial having a penetrable seal. The assembly includes a housing having first and second open ends, and a bore extending between the first and second open ends. The housing is removably connectable to the piston. The assembly also includes a conduit having first and second ends and first and second apertures adjacent to the first and second ends, respectively. The conduit is longitudinally slidable within the bore between a retracted position in which the first aperture is positioned within at least one of the housing and the piston when the housing is connected to the piston, and an activated position in which the first aperture protrudes through the piston into the body of the vessel when the housing is connected to the piston. The assembly further includes a vial socket assembly having a vial socket for receiving and engaging at least a portion of the vial including the penetrable seal and a hollow piercing member having a first open end in fluid communication with the conduit and a second open end for piercing the penetrable closure. The vial socket assembly is moveable longitudinally relative to the housing in concert with the conduit.
Abstract:
Embodiments of the invention relate generally to cartridges, devices and methods for pharmaceutical constituents for storage, mixing and delivery. Particular embodiments relate to a device and method for pharmaceutical constituent mixing and delivery using a double-chambered cartridge within a socket member, for use as part of a syringe device. Other embodiments relate to a cartridge assembly for storing the pharmaceutical constituents prior to mixing and a method of forming the cartridge assembly. Still further embodiments relate to an extensible plunger for actuation of the delivery device. The extensible plunger is actuated in a first stroke while in its retracted state to mix the constituents and is actuated in a second stroke in its extended state to deliver the mixed constituents to an external volume.
