CLAIMS

We claim:

1. An injector configured to receive therein a cartridge containing a substance to be dispensed, the injector comprising:

an injector housing;

a cartridge door movably mounted to the injector housing and having an open end and an interior channel to receive the cartridge therein through the open end, the cartridge door being movable between a fully closed position, wherein the open end is obscured by the injector housing to prevent insertion of the cartridge into the interior channel, and a fully open position, wherein the open end is sufficiently exposed to receive the cartridge therethrough and into the interior channel; a power supply to power at least one power-operated component of the injector;

a power supply circuit electrically connecting the power supply with the at least one power-operated component; and

an electrically insulated arm movable from a first state, whereat the electrically insulated arm is interposed between a contact of the power supply and an opposing contact of the power supply circuit, to a second state, whereat the electrically insulated arm is removed from between the contact of the power supply and the opposing contact of the power supply circuit, thereby connecting the power supply with the power supply circuit and providing power to the at least one power-operated component;

wherein the electrically insulated arm is coupled to the cartridge door and initially positioned in the first state thereof in the fully closed position of the cartridge door, whereby movement of the cartridge door out of the fully closed position toward the fully open position moves the electrically insulated arm to the second state thereof.

2. The injector of claim 1, wherein upon movement of the electrically insulated arm from the initial first state to the second state, the electrically insulated member remains in the second state thereof irrespective of subsequent movement of the cartridge door.

3. The injector of claim 1 or claim 2, wherein at least one of the contact of the power supply and the contact of the power supply circuit comprises a deflectable finger, the finger having a natural position in which the finger contacts the opposing contact, wherein the finger is deflected away from the natural position thereof in the first state of the electrically insulated arm and the finger returns to the natural position thereof when the electrically insulated arm moves to the second state thereof.

4. The injector of claim 3, wherein the finger comprises a terminal free end, the terminal free end defining an incline extending from the terminal free end in a direction away from the opposing contact, whereby movement of the electrically insulated arm from the second state thereof in a direction toward the first state thereof slides the electrically insulated arm along the incline and away from being re-interposed between the finger and the opposing contact.

5. The injector of any one of the preceding claims, wherein the electrically insulated arm reaches the second state thereof in the fully open position of the cartridge door.

6. The injector of any one of the preceding claims, wherein the cartridge door is pivotably mounted to the injector housing, the electrically insulated arm being pivotable with the cartridge door from the first state to the second state thereof.

7. The injector of any one of the preceding claims, wherein the electrically insulated arm is permanently mounted within the injector housing.

8. The injector of any one of the preceding claims, further comprising a biasing member applying a biasing force upon the cartridge door, thereby biasing the cartridge door toward the fully open position thereof.

9. The injector of claim 8, further comprising an arm positioned in a blocking position blocking the cartridge door from reaching the fully open position thereof under the bias forcing of the biasing member, the arm being deflectable from the blocking position upon application of a force in addition to the biasing force, thereby enabling the cartridge door to reach the fully open position thereof.

10. The injector of claim 9, wherein the cartridge door includes a window in a sidewall thereof, the arm being positioned to catch onto the window in the blocking position and the arm being deflectable out of engagement with the window upon application of the force in addition to the biasing force to enable the cartridge door to reach the fully open position thereof.

11. The injector of any one of claims 8-10 in combination with an injector packaging, the packaging being configured to maintain the cartridge door in the fully closed position thereof, against the biasing force of the biasing member, when the injector is positioned in the packaging.
