A reduced profile syringe assembly is provided that includes an overall profile that is substantially similar to a profile of a syringe barrel. The syringe assembly includes a plunger rod that is significantly disposed within the syringe barrel when filled for use, with the plunger rod adapted to be retracted from the syringe barrel during dispensing of contents of the syringe barrel.

A vial adaptor assembly, suitable for use with a vial containing a medicament and a syringe adaptor, which is in turn connectable to a syringe having a piston adapted for selectable displacement in a first direction for drawing fluid into the syringe and in a second direction for expelling fluid from the syringe, the vial adaptor assembly including: a vial connector for non-removable connection with the vial containing a medicament; a syringe adaptor connector for connection with the syringe adaptor; a pressure equalization chamber having a variable volume, which is sealed from the outside environment during use; a liquid pathway communicating between an interior of the vial containing the medicament and an interior of the syringe when the syringe adaptor is connected to the syringe adaptor connector and the syringe is connected to the syringe adaptor and the vial connector is connected to the vial containing the medicament; and a venting pathway communicating between the interior of the vial containing the medicament and an interior of the pressure equalization chamber, when the vial connector is connected to the vial containing the medicament, wherein the pressure equalization chamber and the venting pathway are mutually configured such that, when the syringe adaptor is connected to the syringe adaptor connector and the syringe is connected to the syringe adaptor and the vial connector is connected to the vial containing the medicament, substantially all of any of the medicament that becomes located within the pressure equalization chamber is removed therefrom via the venting pathway and returned to the interior of the vial by displacement of the piston of the syringe in the first direction.

A reduced profile syringe assembly is provided that includes an overall profile that is substantially similar to a profile of a syringe barrel. The syringe assembly includes a plunger rod that is significantly disposed within the syringe barrel when filled for use, with the plunger rod adapted to be retracted from the syringe barrel during dispensing of contents of the syringe barrel.

A self-righting device is disclosed having a support body for supporting a medicament delivery device, where the support body has a mass, a center of gravity (G) and a shape such that the self-righting device, when positioned on a substantially horizontal surface, moves from an unbalanced position to an upright position. The self-righting device can also have a mechanical adaptor configured for attachment to the support body and for holding an elongated medicament delivery device at an angle less than 30 degrees from a vertical axis when the self-righting device is in the upright position. An assembly of a self-righting device and an elongated medicament delivery device is also provided.

Methods and apparatus to reduce deadspace in syringes and other devices with the use of volume displacing members that occupy space within one or more interior spaces of such devices. The volume displacing members are also equipped with one or more internal flow passages that facilitate a flow of a fluid through it. The volume displacing members are also adapted to cooperate with features of the devices that house them to form air-tight and liquid-tight seals that at least partially determine a fluid pathway through the devices.

A device configured to administer a medication can comprise a lower housing that includes a housing latch. The device can further comprise a needle guard that is movable relative to the lower housing along a first direction from a first position to a second position so as to expose a needle, and an upper housing supported relative to the lower housing. The upper housing can be configured to move with respect to the lower housing along a second direction from a pre-use position to a dispensed position. The housing latch can releasably interfere with the upper housing when the upper housing is in the pre-use position so as to prevent the upper housing from moving toward the dispensed position, and the movement of the needle guard toward the second position, causes the interference to be removed, thereby allowing the upper housing to move toward the second position.

Drug delivery system, injection device, transfer apparatus, vial holder and method of administering and transferring are disclosed. The system may include transfer apparatus and an injection device. The transfer apparatus may have receiving stations for a drug source, such as a vial or vial holder, and for an injection device, and fluid flow pathways for transferring drugs from the source into the injection device. The injection device may include an expandable elastic bladder and an injection cannula that is movable between a plurality of positions.

Disclosed is a device for the parenteral delivery of a medication, such as a drug. The device includes upper and lower housings in which the upper housing is configured to move relative to the lower housing as a result of application of an external force to permit the user of the device to control the rate at which the drug is administered.

A vial adaptor assembly, suitable for use with a vial containing a medicament and a syringe adaptor, which is in turn connectable to a syringe having a piston adapted for selectable displacement in a first direction for drawing fluid into the syringe and in a second direction for expelling fluid from the syringe, the vial adaptor assembly including: a vial connector for non-removable connection with the vial containing a medicament: a syringe adaptor connector for connection with the syringe adaptor; a pressure equalization chamber having a variable volume, which is scaled from the outside environment during use; a liquid pathway communicating between an interior of the vial containing the medicament and an interior of the syringe when the syringe adaptor is connected to the syringe adaptor connector and the syringe is connected to the syringe adaptor and the vial connector is connected to the vial containing the medicament; and a venting pathway communicating between the interior of the vial containing the medicament and an interior of the pressure equalization chamber, when the vial connector is connected to the vial containing the medicament, wherein the pressure equalization chamber and the venting pathway are mutually configured such that, when the syringe adaptor is connected to the syringe adaptor connector and the syringe is connected to the syringe adaptor and the vial connector is connected to the vial containing the medicament, substantially all of any of the medicament that becomes located within the pressure equalization chamber is removed therefrom via the venting pathway and returned to the interior of the vial by displacement of the piston of the syringe in the first direction.

A syringe cover device comprises a first cap with a first frame and a first seal coupled thereto, and a second cap with a second frame and a second seal coupled thereto. The first frame and the second frame are couplable to each other to form an accommodating space therebetween. The first seal and the second seal are couplable to each other to form a main seal body and disposed in the accommodating space. The main seal body has a first surface abutting against the first frame and the second frame, a second surface opposite to the first surface and an aperture formed through the first surface and the second surface. The first frame and the second frame may be attached to a syringe flange with the syringe plunger passing through the aperture to cover and seal a back opening of the syringe barrel.
