20130218090 | SAFETY DEVICE FOR A PRE-FILLED SYRINGE AND INJECTION DEVICE - 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 (L | 08-22-2013 |
20130324923 | Safety Device for a Pre-Filled Syringe and Injection Device - According to the invention, a safety device for a pre-filled syringe comprises a hollow support body for mounting the pre-filled syringe therein, a hollow needle shield that is slidable relative to the support body and guiding means for guiding the movement of the needle shield relative to the support body. The guiding means comprise a flexible arm with a guide pin, a guide track and a separating wall. The guide pin extends from the flexible arm in a radial direction, and protrudes into the guide track. The separating wall extends into the guide track in a direction parallel to a central axis of the safety device. When the needle shield is slid relative to the support body the guide pin moves along the guide track to deflect the flexible arm in a lateral direction perpendicular to the central axis and the movement of the guide pin along the guide track is guided by the interplay of the flexible arm and the separating wall. | 12-05-2013 |
20140221937 | NEEDLE SAFETY DEVICE - Described is a needle safety device comprising a needle hub adapted to couple to an injection device a needle coupled to the needle hub and having a distal tip, a needle shield telescopically coupled to the needle hub and including a biasing element, and a locking element arranged on the needle hub. When the needle shield is in a first axial position, the needle shield covers the distal tip of the needle. When the needle shield is in a second axial position, the needle shield moves proximally relative to the needle hub to expose the distal tip of the needle and the locking element deflects the biasing element. When the needle shield is in a third axial position, the locking element engages the biasing element and the needle shield covers the distal tip of the needle. | 08-07-2014 |
20140236095 | Needle Safety Device - 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 (PA | 08-21-2014 |
20140236100 | Needle Safety Device - Described is a needle safety device comprising a needle hub having a radial protrusion, a needle coupled to the needle hub and having a distal tip, and an inner sleeve telescopically coupled to the needle hub. The inner sleeve includes a first track adapted to engage the radial protrusion. The first track includes an axial section and a radial section. When the inner sleeve is in a first advanced position (PA | 08-21-2014 |
20140243755 | Needle Safety Device - Described is a needle safety device comprising a needle hub, a needle coupled to the needle hub and having a distal tip, an outer needle shield telescopically coupled to the needle hub, and an inner needle shield telescopically coupled to the outer needle shield. The needle safety device has a first state in which the distal tip is covered by the inner needle shield and the inner needle shield is movable in a proximal direction relative to the outer needle shield, a second state in which the distal tip is exposed from the inner needle shield, and a third state in which the distal tip is covered by the inner needle shield and the inner needle shield is immovable in the proximal direction relative to the outer needle shield. The needle safety device includes a first locking mechanism (L | 08-28-2014 |
20140243760 | NEEDLE SAFETY DEVICE - Described is a needle safety device comprising a needle hub including a latch element, a needle coupled to the needle hub and having a distal tip, and a needle shield telescopically coupled to the needle hub. The needle shield includes a resilient arm adapted to engage the latch element. When the needle shield is in a first axial position relative to the needle hub, the needle shield covers the distal tip of the needle. When the needle shield is in a retracted position relative to the needle hub, the needle shield is retracted to expose the distal tip of the needle and the arm is deflected radially. When the needle shield is in a second axial position relative to the needle hub, the needle shield covers the distal tip of the needle and the arm engages the latch element to prevent proximal movement of the needle shield relative to the needle hub. | 08-28-2014 |
20140249481 | Needle Safety Device - 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. | 09-04-2014 |
