摘要:
A portable auto-injector configured to store a dry medication separately from a liquid component, wherein removal of a cap opens a rotary valve allowing for the initiation of a mixing step prior to injection. An extendable needle guard is provided over the delivery assembly which prevents premature injection as well as inadvertent sticks or other cross contamination of a needle. The needle guard can also form part of a secondary trigger mechanism which injects the reconstituted drug after the mixing stage is complete.

A portable auto-injector configured to store a dry medication separately from a liquid component, wherein removal of a cap operates a first actuation mechanism which opens a sliding valve and thus allows for the initiation of a mixing step prior to injection. An extendable needle guard is provided over the delivery assembly which prevents premature injection as well as inadvertent sticks or other cross contamination of a needle. The needle guard can also form part of a secondary trigger mechanism which injects the mixed components after the mixing stage is complete.

A mixing and dispensing device (1) for preparing and applying an adhesive consisting of at least two components, comprises a syringe body (2) which encloses a substantially cylindrical cavity (3), wherein the cavity (3) is divided into at least two chambers separated from each other by a movable separating element (6), wherein—a first chamber (4) has a first component (13) of the adhesive and—a second chamber (5) has a second component (14) of the adhesive, wherein a flow path (11) between the first chamber (4) and the second chamber (5) can be released by moving the separating element (6).

An automatic mixing device, an actuating device removably mounted to the automatic mixing device and a retractable syringe having the automatic mixing device are provided. The actuating device has an initially compressed spring and a trigger member that initiates spring decompression to drive depression of a mixing plunger of the automatic mixing device. A seal located in the outer chamber is capable of axial movement upon depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in an inner barrel to a second position intermediate the apertures and vents in an outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in an inner chamber of the inner barrel. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.

An apparatus includes a medicament container, a first elastomeric member, a second elastomeric member and a stopper. The first and second elastomeric members are disposed within the medicament container. The first elastomeric member, a first portion of the medicament container and the second elastomeric member collectively define a medicament volume. The stopper is coupled to a distal end portion of the medicament container. The second elastomeric member, a second portion of the medicament container and the stopper collectively define a vent volume. A first retainer of the stopper is configured to engage a first portion of a carrier to limit movement of the medicament container when in a first position. A second retainer of the stopper is configured to engage a second portion of the carrier to limit movement of the medicament container when in a second position.

A container closure delivery system that is suitable for lyophilized pharmaceutical injectable powder products is disclosed. The system comprises storage stable powder formulations and a container closure assembly design wherein the formulation can be filled and lyophilized with a standard fill finish equipment, and the formulations and lyophilization processes are optimized to produce a powder that readily dissolves upon contact with a diluent, thereby facilitating the direct injection of the lyophilized product without the need for a separate reconstitution/mixing/priming step.
摘要:
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.

Drug delivery devices adapted to receive liquid medication to fill a reservoir, utilize sliding through valves that are closed except when driven by force of liquid medication pushed by a plunger to an open position to feed the medication via needle to a patient or via a connection to an IV port. The devices have multiple seals and automatically close up when pressure on the plunger is released. The methodology is also included.
