摘要:
The present invention relates to a needle including: a needle hub having a needle with a distal tip; a ring for protecting the needle in one of a storage condition or end-of-use condition of the needle assembly; a foldable element for moving the protective ring; a biasing element for urging the foldable element from its folded configuration to an unfolded configuration; a retainer for maintaining the biasing element in an intermediate stressed state at least in the storage condition of the needle assembly; and a deactivating element for releasing said retainer at least at the end of the injection step. The invention also relates to an injection device including such a needle assembly and a container.
摘要:
The present invention relates to a device for automatic injection including a container, a piston and a piston rod coupled to the piston during the injection. A biasing element is provided for causing distal movement of the piston rod with respect to the container, with a housing receiving the container, the piston rod and the biasing element. The device further including a controlling arrangement for producing an audible indicator at the end of injection.

The present invention relates to an injection device (1) comprising:—a container (5) receiving a product, and provided with an injection needle (6),—a housing (9, 11) receiving said container, said container being movable relative to said housing between an initial position, an insertion position, and a final position,—retaining means (12, 15), for maintaining said container in said insertion position,—deactivating means (20), for releasing said retaining means, said device being characterized in that it comprises:—temporizing means (19, 26, 27), for controlling the release of said retaining means until substantially all of the product contained within said container has passed through said injection needle before said container moves to said final position, and—a needle shield (2) coupled with said housing (9, 11) removal of said needle shield being with limited or no rotation of said needle shield. The invention also concerns a kit comprising such a device.

The present invention relates to a device (1) for automatic injection of a product (3) and a needle (6). The device comprises:—a housing (8) for the container (5), the container being movable relative to the housing between an initial position, in which a tip of the needle does not extend beyond a distal end of the housing and in which the container is in one of a passive state and an active state, to an insertion position, distally spaced relative to the initial position and in which the tip of the needle extends beyond the distal end of the housing, movement of the container out of its first position being prevented when the container is in its passive state, and being permitted when the container is in its active state, and—a safety shield (10) coupled to the housing (8) for movement between a first position and a second position in which the tip of the needle does not extend beyond a distal end of the shield—a needle shield (2) coupled with said housing and covering the needle prior to use of said device, removal of said needle shield being with limited or no rotation of said needle shield.
摘要:
The invention relates to a device (1) for delivering two predetermined doses of a product (3), comprising:—a container (2) for containing said product, said container having a distal end (2d) through which the product is delivered under the distal pressure of a piston,—a pusher (7) movable with respect to said container for causing said piston (4) to move in the distal direction from an initial position, in which none of said product has been expelled to a first position, in which a first dose of said product has been expelled, and to a second position, in which a second dose of said product has been expelled,—a holder body (15) receiving said container and said pusher (7),—biasing means (22) for urging said pusher (7) in the distal direction, from the initial to the first position, and to the second position,—first and second retaining means (9, 11, 19) for maintaining said pusher (7) in said initial position, and in said first position,—first and second actuation means (18) to deactivate said first and second retaining means (9, 11, 19), characterized in that said first and/or second actuation means (18) are at least rotationally displaceable, said rotation causing at least part of the deactivation of said first and/or second retaining means (9, 11, 19).
