摘要： 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.

摘要： An apparatus for removing a needle shield from a syringe may be configured to receive the removable needle shield. The remover may include a body and a deflectable arm. The deflectable arm may include a distal end coupled to the body and a proximate end distal a proximate end of the body. The deflectable arm may be configured to engage and apply a force to the needle shield when the cap is detached from the syringe, thereby removing the needle shield from the syringe.

摘要： An exemplary embodiment of an injector includes a trigger mechanism, an energy source, and a user-operable firing-initiation member. The trigger mechanism can include a floating trigger member having a retaining portion, a ram assembly having a ram configured to pressurize a medicament container for expelling a medicament therefrom, the ram assembly further having a floating trigger engagement member configured to engage the retaining portion of the floating trigger member when the floating trigger member is in a pre-firing condition. The energy source can be associated with the ram for powering the ram to expel the medicament, and the user-operable firing-initiation member can be operable for causing an axial rotation of the floating trigger member from the pre-firing condition to a firing condition in which the floating trigger engagement member is released from the retaining portion to allow the energy source to fire the ram.

摘要： A dispensing mechanism for delivering a dosage of medicament including a housing having a proximal-distal axis; a plunger rod having a screw thread and configured to advance along the proximal-distal axis relative to the housing; a user-operable push button moveable along the proximal-distal axis relative to the housing; a twist driver threadably engaged with the push button such that movement of the push button towards the distal end of the housing causes rotation of the twist driver about the proximal-distal axis; and a driver engaged with the twist driver such that rotation of the twist driver causes rotation of the driver, the driver also engaged with a portion of the plunger rod such that rotation of the driver causes rotation of the plunger rod, advancing the plunger rod along the proximal-distal axis relative to the housing.
