Abstract: An injection device for injecting medicament in a patient includes a syringe coupled to a housing and radially retained by a retaining rib. A needle guard is slideably coupled to the housing and spring biased in a distal direction by a return spring. A ram is slideably coupled to the housing and spring biased in the distal direction by a main spring. An initial position is defined by a retaining arm being disposed in the longitudinal path of the ram preventing firing. A released position is defined by the retaining arm being clear from the longitudinal path of the ram allowing the ram to extend distally. A locked position is defined by the retaining arm being disposed in the longitudinal path of the ram and a lock arm of the ram being disposed in the longitudinal path of the needle guard preventing the needle guard from being retracted.

Abstract: An injection device for injecting medicament in a patient comprises a housing configured to house a fluid reservoir that has one of a plurality of volumes of medicament. An injection conduit fluidly coupled to the fluid reservoir defines a fluid pathway from the fluid reservoir to the patient. A firing mechanism is coupled to the fluid reservoir and is configured to expel the medicament from the fluid reservoir through the injection conduit. A volume setting mechanism is coupled to the firing mechanism and is configured to select the one of the plurality of volumes of medicament for the firing mechanism to expel. A dose setting mechanism is configured to select all or a fraction of the one of the plurality of volumes of medicament that is injected from the injection conduit when the firing mechanism is actuated.
