Abstract: An auto-injector automatically dispenses a predetermined dose of medicament upon activation. The auto-injector includes a needle cover operative to engage an injection site and activate the injector. The needle cover is configured to move from a locked retracted position prior to a medicament dispensing operation to a locked extended position after the medicament dispensing operation. The non-removable needle cover prevents contact with the needle both before and after the medicament dispensing operation.

Abstract: An auto-injector for dispensing a predetermined dose of medicament is disclosed. The auto-injector includes a needle cover operative to engage an injection site. The needle cover is configured to move from a retracted position prior to a medicament dispensing operation to an extended locked position after the medicament dispensing operation. Any residual activation force remaining after the medicament dispensing operation is contained within the auto-injector and is not directed to the needle cover, thus attenuating, if not eliminating, any kickback effect.

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: 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: A cartridge assembly apparatus for an auto-injector includes a flexible container containing a liquid medicant. A needle hub is connected to the flexible container. A needle is attached to the needle hub and extends proximally from the needle hub. A frame is connected to the needle hub and includes a frame proximal end extending proximally beyond a proximal end of the needle. The needle hub and the needle are displaceable relative to the frame in a proximal direction to insert the needle into a patient.

Abstract: An auto-injector apparatus includes a flexible container containing a liquid medicant, a needle communicated with a container, a housing with a container being received in the housing, a pump disposed in the housing and positioned to engage the flexible container and expel the medicant from the container through the needle upon relative movement between the pump and the container, and a main drive spring operably associated with the needle to extend the needle from a first needle position wherein the needle is completely received in the housing to a second needle position wherein the needle protrudes from the housing. The pump may be a roller.

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.

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 has a plug that is moved from a sealing position into a mixing position 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 assembly allows for better flow through the filter. An actuation assembly drives the plug into the mixing position and forces the mixed medicament through the needle and into the user.

Abstract: In one embodiment, an automatic injector comprises a cartridge adapted to contain a charge of medicament, a seal structure disposed toward a forward end of the cartridge, a plunger normally disposed in a generally rearward end of the cartridge and movable through the cartridge toward a generally forward end thereof in response to an actuating procedure. The movable plunger rearwardly confines the medicament within the cartridge. A needle normally disposed in communication with the medicament container provides a passage in which the medicament is released into an individual's flesh in response to an actuating procedure projecting the needle into the flesh of the individual. The cartridge having an increased friction region so as to slow the motion of the plunger when the forward end of the needle travels through the seal in order to eliminate coring.

Abstract: A separation assembly for initially keeping a first component separate from a second component includes a generally cylindrical body slidably supported within a container between the first and second components. The body includes a seal structure having an inner seal member that initially seals the first component from the second component. In response to a predetermined operating condition, the inner seal member allows the first component to flow through at least one flow path in the seal structure to mix with the second component. The body further includes a flow distributing member disposed adjacent the seal structure to evenly distribute the first component into the second component. The seal structure and the flow distributing member form a single unit.
