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;

a movable member operably connected with the body, the movable member having an opening;

an injection needle displaceable relative to the reservoir and adapted to penetrate 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 for limiting movement of the movable member, the second portion comprising a lockout pin, the first portion and the lockout pin being insertable through a same body opening of the body;

wherein the second portion extends directly from the first portion.

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

3. The device according to claim 1, wherein the needle cover comprises a handle portion rotatable relative to the first portion.

4. The device according to claim 3, wherein the second portion is disposed on the handle portion.

5. The device according to claim 1, further comprising an adhesive pad disposed on the body for contacting a patient'"'"'s skin.

6. A drug delivery device, comprising:

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

a movable member disposed at least partially within the body and movable along a path, the movable member having 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 portion for covering the injection needle and a second portion comprising a lockout pin movable from a first position preventing device activation to a second position enabling device activation;

wherein the second portion extends directly from the first portion;

wherein the first portion and the lockout pin are insertable into a same body opening in the body;

wherein in the first position, the lockout pin extends longitudinally in a first direction transverse to the path and is disposed in the opening of the movable member; and

wherein the needle cover is removable from the body to enable device activation.

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

8. The device according to claim 6, further comprising an adhesive pad disposed on the body for contacting a patient'"'"'s skin.

9. A drug delivery device, comprising:

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

an injection needle displaceable relative to the reservoir and adapted to penetrate the skin of a patient, the needle providing a path for the medicament between the reservoir and the patient, and having a longitudinal axis that is not parallel to a longitudinal axis of the reservoir;

a movable member movably disposed at least partially within the body, the movable member having an opening; and

a needle cover having;

a first portion for covering the injection needle; and

a second portion for preventing device activation, the second portion comprising a lockout pin disposed in the opening of the movable member when preventing activation;

wherein the second portion extends directly from the first portion; and

wherein the first portion and the lockout pin are insertable into a same body opening in the body.
