An injector device includes a housing for receiving a medicament cartridge; a needle unit comprising a needle; and a first sleeve slideable along a longitudinal axis of the housing from a first position, in which the first sleeve conceals the needle, to a second position, in which the needle is exposed from an end of the first sleeve, the first sleeve configured to engage the needle unit so that, during use, movement of the first sleeve from the first position to the second position moves the needle unit from a primary position to a secondary position, in which secondary position the needle unit locates over an end of a medicament cartridge when a medicament cartridge is received in the device, wherein the device further comprises a second sleeve arranged to move telescopically with respect to the first sleeve, the first sleeve extending from the second sleeve when the first sleeve is in the first position.

The safety syringe assembly is for inserting a needle into a patient and comprises a needle hub assembly and a safety cover. The needle hub assembly includes a needle, needle hub, and hub flex unit. The needle is mounted on the front side of the needle hub while the rear side is for receiving a syringe. The safety cover houses the needle hub assembly in a first position during shipping, a second position during insertion of the needle into the patient, and in a third position after the needle has been inserted into the patient while awaiting disposal. A portion of the safety cover includes magnification enabling a user to view a dosage calibration scale, needle bevel and air bubbles. The hub flex unit assumes a first enlarged position during shipping, is compressed during insertion into the patient, and slides into a third position after usage while awaiting disposal.

A syringe safety device is disclosed herein that comprises a shaft configured to support a barrel of a syringe, a guard configured to be disposed inside the shaft before the syringe is used and to extend outwardly from the shaft after the syringe is used, and a lock disposed between the guard and the shaft having a lock head disposed at a first end thereof, the lock head being disposed in a first aperture in the shaft before the syringe is used and in a second aperture in the shaft after the syringe has been used. A method of using the device also is described.

A safety device for an injection syringe including a syringe support, a protective sheath for protecting an injection needle carried by the injection syringe, the protective sheath being mounted to slide relative to the syringe support between an injection position in which the needle is uncovered, and a protection position in which the needle is covered, the protective sheath having an initial grip surface enabling the device to be gripped by a user, the initial grip surface being a projection that extends outward from the protective sheath, and a return spring for urging the sheath into the protection position. The sheath also includes an extender member for extending the initial grip surface, being a separate piece from the protective sheath, attached to the protective sheath in such a manner as to present an enlarged grip surface, larger than the initial grip surface.

A medicament delivery device has a syringe, a housing, a needle shield, a biasing member and one or more blocking members. The needle shield is biased axially forwardly by the biasing member so as to selectively cover a needle of the syringe. However, the biasing member is prevented from biasing the needle shield axially forwardly until a radial movement of the blocking members has occurred, which is precipitated by a forward axial movement of the syringe. Consequently, the forward movement of the syringe releases the needle shield to automatically make safe the device.

A needle cover assembly can be used with a medicament delivery device, wherein said needle cover assembly is disposable and comprises a retainer element connectable to a medicament container holder; a hub having a longitudinal axis and comprising a double pointed injection needle with a proximal needle end and a distal needle end, wherein the proximal needle end projects a distance from the hub along the longitudinal axis, and a shield covering at least the proximal needle end and a portion of the hub. Said shield comprises a detachable element, that the shield is attached to the hub when said detachable element is attached to the shield, corresponding to an untampered state, and that the shield is released and is telescopically movable in relation to the hub along the longitudinal axis when said detachable element is detached from the shield corresponding to an activated state.

A safety pen needle includes: a main body, a cannula fixed to the main body and at least partially projecting out of the main body, a lock element placed inside the main body, a thrust element placed inside the main body, and a shield movable relative to the main body while remaining at least partially inserted within the main body. The pen needle is configured to move from a first configuration, in which the shield entirely covers an upper end of the cannula, to a second configuration, in which the upper end of the cannula is exposed, due to the action of external thrust. The pen needle is configured to move from the second configuration to an irreversible third configuration, in which the shield entirely covers the upper end of the cannula, due to the action of thrust exerted by the thrust element.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The safety needle device may include an activation latch, a lockout latch, a tether and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection. The safety needle device may include a slider element disposed above an activation latch. A method of drug delivery is also disclosed.

Medicinal fluid delivery devices and methods for advancing and retracting needles are disclosed. According to an aspect, a medicinal fluid delivery device includes a tube that defines an interior space that extends between a first and second openings. The device includes a needle including a proximal end and a distal end that substantially align in a first direction. A portion of the distal end is biased to extend in a second direction different than the first direction. A mechanism is attached to the proximal end and configured to position the distal end between a first position and a second position. In the first position, the portion of the distal end is constrained by the interior wall such that is does not extend in the second direction. In the second position, the distal end is not constrained by the interior wall such that it extends in the second direction.
