Holder for medicament injector, medicament injection assembly, and methods of use

A medicament injection assembly comprising:

• an injector pen for injecting a medicament into a patient;
• and
• a holder for the injector pen, wherein the holder comprises:
• a main body with an injector receiver for receiving the injector pen therein;
• a needle carousel rotatably coupled to the main body, the needle carousel comprising a plurality of needle receivers for holding needles therein, wherein the needle carousel rotates on the main body to successively align each needle receiver with the injector receiver;
• and
• an actuator that shifts the injector pen toward an aligned one or the needle receivers, operatively mounts a needle in the aligned needle receiver on the injector pen, and shifts the needle mounted on the injector pen out of the needle receiver so as to expose the needle on an exterior of the holder.

A method of administering a dose of medicament from an injector pen operatively carried in a holder, wherein the holder comprises a main body with an injector receiver for receiving the injector pen, a needle carousel rotatably coupled to the main body and having a plurality of needle receivers holding needles therein, and an actuator that shifts the injector pen operatively disposed in the injector receiver toward an aligned one or the needle receivers, the method comprising:

• rotating the needle carousel relative to the main body to align a needle disposed in one of the needle receivers with the injector pen;
• engaging the actuator to shift the injector pen into engagement with the aligned needle, operatively mount the aligned needle onto the injector pen, and advance the needle from the needle receiver until exposed on and protruding from an exterior of the holder;
• and
• administering the dose of the medicament through the needle.
