Abstract: An automatic medicament injector having a compartment for a dry medicament component and a compartment for a wet medicament component. The two compartments are separated by a seal structure that converts from a sealing condition to a mixing condition when the device is activated. The seal structure includes a wiper that scrapes the interior walls in the dry component compartment to prevent the dry component from accumulating at the seal/glass interface. A tapered insert funnels the mixed medicament components to an attached needle assembly, but can be removed when the device is filled. A filter is provided between the medicament compartments and the needle assembly. A chamber between the filter and the needle allows for better flow through the filter. An actuation assembly drives the seal structure into the mixing condition and forces the mixed medicament through the needle and into the user.

Abstract: An automatic injection device including a housing, a chamber with a first compartment and a second compartment, and a seal structure between the compartments. The seal structure is initially in a sealing condition that seals the first compartment from the second compartment, where the seal includes a plug and an outer sealing member. The plug is slidably movable within the outer sealing member to convert the seal structure from the sealing condition to a mixing condition by opening a path between the first compartment and the second compartment. The automatic injection device also includes a needle assembly and an activation assembly. Activation of the activation assembly causes (1) pressurization of the first compartment, (2) the seal structure to convert from the sealing condition to the mixing condition, and (3) the first and second medicament components to be mixed and forced through the needle assembly.

Abstract: An automatic medicament injector has a first compartment for a first medicament component and a second compartment for a second medicament component. The two compartments are separated by a seal structure that converts from a sealing condition to a mixing condition when the device is activated. The seal structure has a plug that opens a flow path through the seal structure to allow the second medicament component to mix with the first medicament component in the first compartment when the seal structure is in the mixing condition.

Abstract: A drug delivery system includes an automatic injector that can deliver a small, precise amount of a therapeutic agent. The automatic injector includes a chamber for containing a liquid component and a thin porous member that carries thereon and/or therein the small, precise amount of therapeutic agent. Upon activation of the automatic injector, a flow path opens from the chamber through the porous member, enabling the liquid component to rapidly mix with the therapeutic agent before being injected.

Abstract: A needle and hub assembly for automatic injectors includes a cap or skirt that has a forward surface interposed between and reinforced by first and second engaged hub portions. A needle is received in a contiguous channel formed in the two hub portions. Methods of forming the assembly include molding the first hub portion, placing the cap over the first hub portion, inserting the needle into the channel in the first hub portion, and then overmolding or otherwise forming the second hub portion on the exterior of the first hub portion and cap such that the second hub portion engages the first hub portion. An assembly created by this “two-shot” process can be used to seal a relatively large opening in a medicament cartridge and to support the needle more effectively than a conventional assembly.

Abstract: An automatic injector separately stores liquid and dry components in respective compartments. When the injector is activated, a fluid-directing member between the liquid and dry compartments causes the liquid component to form a vortex as the liquid flows into the dry compartment. This allows the two components to combine more thoroughly and quickly to form a liquid solution that is delivered to an injection site.
