Automatic injection device

An automatic injection device for providing a subcutaneous injection of a TNF inhibitor into a user, comprising:

• a housing having an open first end, a second end and a window disposed in a side wall for viewing the interior of the housing;
• a syringe movably disposed in the housing, the syringe including a barrel portion for holding the TNF inhibitor, a hollow needle in fluid communication with the barrel portion for ejecting the TNF inhibitor from the syringe, and a bung for sealing the barrel portion and selectively applying pressure to the TNF inhibitor to force the TNF inhibitor through the hollow needle;
• an actuator for selectively moving the syringe towards a first end of the housing so that the needle extends from the first end of the housing;
• and
• an actuator for expelling the TNF inhibitor from the syringe after movement of the syringe towards the first end of the housing.

An automatic injection device for providing a subcutaneous injection of a TNF inhibitor into a user, comprising:

• a housing having an open first end, a second end and having a window formed in a side wall thereof,
• a syringe movably disposed within the housing for storing and selectively ejecting the TNF inhibitor from the open first end;
• and
• an indicator that aligns with the window in the side wall when the syringe is substantially empty of the TNF inhibitor.

An automatic injection device for providing a subcutaneous injection of a substance into a user, comprising:

• a housing having an open first end and a second end;
• a plunger including a rod configured to be connected or adjacent at a first end to a bung of a syringe, a compressible portion projecting from the rod along at least a portion of a length of the rod, the compressible portion having a first expanded position for moving a syringe towards the first end of the housing and a second compressed position for applying a pressurizer to the bung, and a flange between a second end of the rod and the compressible portion;
• and
• a biasing mechanism for biasing the plunger towards the first open end of the housing, the biasing mechanism disposed about the second end of the rod between the flange and the second end of the housing.

A article of manufacture, comprising:

• an automatic injection device having a pre-filled syringe containing a dose of a TNFα inhibitor;
• and
• an alcohol preparation pad,
• packaged with instructions for use to treat arthritis by injecting the dose into the skin of a user using the automatic injection device.

A device for training a user to use an automatic injection device, comprising

• a housing having a window,
• an activation button coupled to a first end of the housing;
• and
• an indicator movably disposed within the housing, wherein the indicator aligns with the window of the housing after a user activates the activation button.

A kit for training a recipient on use of an automatic injection device, wherein the automatic injection device comprises a needle and a medication, the kit comprising:

• (a) a demonstration automatic injection device which lacks the needle and the medication, the demonstration device comprising a housing having a window, an activation button coupled to a first end of the housing;
• and an indicator movably disposed within the housing, wherein the indicator aligns with the window of the housing after a user activates the activation button;
• and
• (b) instructions for using the automatic injection device.

An audiovisual device for training a recipient on use of an automatic injection device, wherein the automatic injection device comprises an activator mechanism and a medication, the audiovisual device conveying to the recipient instructions to:

• (a) position the automatic injection device at an injection site;
• (b) engage the activator mechanism to begin injection of the medication;
• (c) maintain engagement of the activator mechanism for a prescribed period of time to continue injection of the medication or until a visible indicator of completion is detected;
• and
• (d) remove the automatic injection device from the injection site after passage of the prescribed period of time or once the visible indicator of completion is detected.

A method of training a recipient on use of an automatic injection device, wherein the automatic injection device comprises an activator mechanism and a TNF inhibitor, the method comprising conveying to the recipient instructions to:

• (a) position the automatic injection device at an injection site;
• (b) engage the activator mechanism to begin injection of the TNF inhibitor;
• (c) maintain engagement of the activator mechanism to continue injection of the TNF inhibitor until a visible indicator of completion is detected or for a prescribed period of time to continue injection of the TNF inhibitor;
• and
• (d) remove the automatic injection device from the injection site once the visible indicator of completion is detected or after passage of the prescribed period of time.

An automatic injection device for providing a subcutaneous injection of an antibody, or antigen binding portion thereof, into a user, comprising:

• a housing having an open first end, a second end and a window disposed in a side wall for viewing the interior of the housing;
• a syringe movably disposed in the housing, the syringe including a barrel portion for holding the antibody, or antigen binding portion thereof, a hollow needle in fluid communication with the barrel portion for ejecting the antibody, or antigen binding portion thereof, from the syringe, and a bung for sealing the barrel portion and selectively applying pressure to the antibody, or antigen binding portion thereof, to force the antibody, or antigen binding portion thereof, through the hollow needle;
• and
• an actuator including a first biasing mechanism for selectively moving the syringe towards a first end of the housing so that the needle extends from the first end of the housing and for expelling the antibody, or antigen binding portion thereof, from the syringe after movement of the syringe towards the first end of the housing.
