Abstract

A drug delivery device, including a body (104, 116) having a reservoir (160) disposed therein for containing a medicament and an injection needle (152) for penetrating the skin of a patient, the needle (152) providing a path for the medicament between the reservoir (160) and the patient. The device also includes a rotor (580) rotatably disposed in the body (104, 116) for activating the device upon rotation of the rotor (580), a needle cover (112) for covering the injection needle, and a needle cover clip (560) disposed on the needle cover (112) to rotate from a first position preventing rotor rotation to a second position permitting rotor rotation.

Claims

1. A drug delivery device, comprising:

a body having a reservoir disposed therein for containing a medicament, and an opening;

an injection needle for penetrating the skin of a patient, the needle providing a path for the medicament between the reservoir and the patient; and

a needle cover having;

a first, needle-covering portion for covering the injection needle; and

a second portion for preventing device activation, the first and second portions being insertable through the opening.

2. The device according to claim 1, wherein the second portion is adapted to prevent device activation until the needle-covering portion is removed to uncover the needle.

3. The device according to claim 1, wherein the second portion is engageable with an element disposed in the interior of the body to prevent activation.

4. The device according to claim 1, wherein the second portion comprises a pin.

5. The device according to claim 1, wherein the first portion is directly connected to the second portion.

6. The device according to claim 1, wherein the first and second portions are integrally formed as a unitary structure.

7. The device according to claim 1, wherein the needle cover comprises a handle portion rotatable relative to the needle-covering portion.

8. The device according to claim 7, wherein the second portion is disposed on the handle portion.

9. A drug delivery device, comprising:

a body having a reservoir disposed therein for containing a medicament;

an injection needle for penetrating the skin of a patient, the needle providing a path for the medicament between the reservoir and the patient; and

a needle cover having a first portion for covering the injection needle and a second portion movable from a first position preventing device activation to a second position enabling device activation.
