摘要： Described is a needle safety device comprising a needle hub including a plurality of resilient arms having detents, a needle having a distal tip, and a needle shield telescopically coupled to the needle hub. The needle shield includes a plurality of axial slots adapted to engage the detents on the resilient arms and the detents are axially movable in the slots. The needle shield includes a plurality of grooves separated from the slots by separation walls and the grooves are adapted to engage the detents. When the needle shield is in a first position relative to the needle hub, the needle shield covers the distal tip of the needle and the detents are engaged in the slots. When the needle shield is in a second position relative to the needle hub, the distal tip of the needle protrudes through an aperture in the needle shield and the detents are engaged in the slots. When the needle shield is in a third position relative to the needle hub, the needle shield covers the distal tip of the needle and the detents are engaged in the grooves. In the third position, the detents are adapted to abut the separation walls and prevent proximal movement of the needle shield relative to the needle hub.

摘要： According to the invention a safety device for a pre-filled syringe comprises a substantially cylindrical and hollow support body and a hollow needle shield slideably arranged relative to the support body. The support body comprises at least one resilient arm and the hollow needle shield or a needle shield assembly comprises at least one curved actuation ramp. The curved actuation ramp protrudes in a lateral direction (L) perpendicular to a central axis (A) of the safety device. The curved actuation ramp comprises a first lateral dimension (L1) at a proximal end of the needle shield and a second lateral dimension (L2) exceeding the first lateral dimension (L1) at a distal end of the needle shield. The resilient arm engages the curved actuation ramp when the needle shield is slid relative to the support body.

摘要： Described is a needle safety device comprising a needle hub, a needle coupled to the needle hub and having a distal tip; a needle shield telescopically coupled to the needle hub, the needle shield, a locking element including latch arms adapted to engage the needle hub and engagement elements adapted to engage the needle shield. When the needle shield is in a first axial position (PA1) relative to the needle hub, the needle shield covers the distal tip of the needle and the engagement elements of the locking element engage the needle shield. When the needle shield is in a second axial position (PA2) relative to the needle hub, the needle shield is retracted to expose the distal tip of the needle and the latch arms engage the needle hub. When the needle shield is in a third axial position (PA3) relative to the needle hub, the needle shield covers the distal tip of the needle and the engagement elements abut the needle shield to prevent proximal movement of the needle shield relative to the needle hub.

摘要： A drug delivery device for setting and dispensing a dose of a drug is presented having a support body having a first end defining a first opening and a second end defining a second opening and a centered outer indicator ring. A syringe barrel sealed by a stopper is slidably diposed therein along an axial direction and adapted to have an integrated needle or to be coupled with a needle assembly, wherein the syringe barrel is positioned within the support body. A needle shield is adapted to be coupled to one of the ends of the support body and slidably disposed thereon. An outer body is adapted to be coupled to the other end of the support body and slidably disposed thereon, wherein the outer indicator ring limits the movement of the outer body as well as of the needle shield.

摘要： According to the invention, an injection device (D) comprises a pre-filled syringe and a safety device. The pre-filled syringe comprises a barrel with an inner cavity in fluid communication with a hypodermic needle attached to a distal end of the pre-filled syringe and a piston fluid-tightly sealing a proximal end of the inner cavity. The safety device comprises a support body for retaining the pre-filled syringe therein, an outer body operably connected to the piston, a needle shield and a releasable retaining means (R). The retaining means comprises a radial projection and a longitudinal recess adapted to receive the radial projection. The radial projection is connected to or integral part of one of the support body or the outer body and a longitudinal recess formed into the other of the support body or the outer body. The needle shield, the support body and the outer body are telescopable relative to each other. The piston is movable in a distal direction to expel a medicament contained in the inner cavity through the hypodermic needle by a manual actuation of the outer body. A telescoping movement of the outer body with respect to the support body is restricted by the retaining means (R) when the needle shield is moved with respect to the support body in a proximal direction from an initial position (I) towards a retracted position (II). The retaining means (R) is released when the needle shield reaches the retracted position (II) allowing for a telescoping movement of the outer body with respect to the support body to expel the medicament contained in the pre-filled syringe through the hypodermic needle.

The needle shield, the support body and the outer body are telescopable relative to each other. The piston is movable in a distal direction to expel a medicament contained in the inner cavity through the hypodermic needle by a manual actuation of the outer body. A telescoping movement of the outer body with respect to the support body is restricted by the retaining means (R) when the needle shield is moved with respect to the support body in a proximal direction from an initial position (I) towards a retracted position (II). The retaining means (R) is released when the needle shield reaches the retracted position (II) allowing for a telescoping movement of the outer body with respect to the support body to expel the medicament contained in the pre-filled syringe through the hypodermic needle.
