摘要:
According to the invention, a safety device for a pre-filled syringe comprises a hollow support body to retain 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 guide pin, a guide track and a cut-out adjacent to the guide track. The guide pin protrudes into the guide track and moves within and along the guide track when the needle shield is slid relative to the support body. The cut-out allows a side wall of the guide track to be deflected in a lateral direction perpendicular to a central axis of the safety device.
摘要:
An injection device for administering a liquid is presented that comprises a pre-filled syringe and a safety mechanism for providing needle safety for an injection needle of the pre-filled syringe. The pre-filled syringe comprises a barrel containing the liquid and a stopper translatably disposed within the barrel, where the injection needle attached to a distal end of the barrel. The safety mechanism comprises a substantially cylindrical housing adapted to contain the pre-filled syringe, a plunger connectable to the stopper of the pre-filled syringe and adapted to be translated in a distal direction (D) to expel the liquid through the injection needle, an energizable biasing means arranged between the housing and the pre-filled syringe, wherein the energized biasing means is capable of biasing the pre-filled syringe with respect to the housing in a proximal direction (P) and a retaining mechanism for retaining the pre-filled syringe with respect to the housing in a first retracted position (R1), in an advanced position (A) and in a second retracted position (R2).

A safety device suitable for a pre-filled syringe containing a medicament includes a chassis adapted to be affixed to the pre-filled syringe, a deformable flexible outer structure made from a material with a shape memory, and a substantially cylindrical needle shield affixed or integral to the outer structure. The deformed flexible outer structure is capable of advancing the needle shield with respect to the chassis in a distal direction into a position in which the needle shield projects from the chassis in the distal direction. A biasing force for advancing the needle shield originates from a shape memory effect that causes the deformed flexible outer structure to substantially return to its unstressed shape.

A method for growing planar, semi-polar nitride film on a miscut spinel substrate, in which a large area of the planar, semi-polar nitride film is parallel to the substrate's surface. The planar films and substrates are: (1) {10 11} gallium nitride (GaN) grown on a {100} spinel substrate miscut in specific directions, (2) {10 13} gallium nitride (GaN) grown on a {110} spinel substrate, (3) {11 22} gallium nitride (GaN) grown on a {1 100} sapphire substrate, and (4) {10 13} gallium nitride (GaN) grown on a {1 100} sapphire substrate
摘要:
A method for improved growth of a semipolar (Al,In,Ga,B)N semiconductor thin film using an intentionally miscut substrate. Specifically, the method comprises intentionally miscutting a substrate, loading a substrate into a reactor, heating the substrate under a flow of nitrogen and/or hydrogen and/or ammonia, depositing an InxGa1-xN nucleation layer on the heated substrate, depositing a semipolar nitride semiconductor thin film on the InxGa1-xN nucleation layer, and cooling the substrate under a nitrogen overpressure.
