Automatic injection device
First Claim
1. A device for automatic injection of a product into an injection site, the product being carried by a container having an open proximal end and a substantially closed distal end and having a reservoir defined therebetween, and a needle provided at the distal end and in fluid communication with the reservoir to provide an outlet port for the product from the container, and a piston provided in the container and movable with respect to the container, the movement of the piston causing the product to be expelled from the container through the needle, said device comprising:
- a housing for the container, the container being movable relative to said housing between an initial position, in which a tip of the needle does not extend beyond a distal end of said 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 said initial position and in which the tip of the needle extends beyond said distal end of said housing, movement of the container out of its initial position being prevented when the container is in its passive state, and being permitted when the container is in its active state,a safety shield coupled to said housing 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 said safety shield, movement of said safety shield out of its first position placing the container in its active state, said safety shield being movable to its second position when the container is in said insertion position, said safety shield being secured against proximal movement when in said second position, anda needle shield coupled with said housing and covering the needle prior to use of said device, removal of said needle shield from the device being with limited or no rotation of said needle shield.

Abstract
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.

24. A kit for a device for automatic injection of a product into an injection site, the product being carried by a container having an open proximal end and a substantially closed distal end and having a reservoir defined therebetween, and a needle provided at the distal end and in fluid communication with the reservoir to provide an outlet port for the product from the container, and a piston provided in the container and movable with respect to the container, the movement of the piston causing the product to be expelled from the container through the needle, wherein said kit comprises:
a housing assembly comprising; an upper housing assembly, a lower housing assembly, at least one of said upper and said lower housing assembly being adapted to receive part of the container, the container being movable, when received within said at least one of said upper and said lower housing assembly, between an initial position, in which a tip of the needle does not extend beyond a distal end of said lower housing assembly and in which the container is in one of a passive state and an active state, to an insertion position, distally spaced relative to said initial position and in which the tip of the needle extends beyond said distal end of said lower housing assembly, 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; means for connecting said upper housing and said lower housing together, and a safety shield coupled to one of said upper and said lower housing assembly 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 said safety shield, movement of said safety shield out of its first position placing the container in its active state, said safety shield being movable to its second position when the container is in said insertion position, said safety shield being secured against proximal movement when in said second position, and a needle shield coupled with one of said upper and said lower housing assembly 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. - View Dependent Claims (25)
