Abstract:
An auto-injector operable in a single activation step. The auto-injector is automatically armed when removed from its carrying receptacle. The auto-injector may be prefilled with more than one constituent of a beneficial agent, stored in separated compartments, in such an arrangement that the compartments will automatically merge when the auto-injector is removed from its carrying receptacle.
Abstract:
A portable auto-injector configured to store a liquid component in a first chamber separately from a dry medication in a second chamber, wherein a first actuation mechanism opens a valve allowing for the initiation of a mixing step prior to injection. The first chamber and second chamber are independent and movable with respect to one another. 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.
