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.
Claims8
A drug delivery device, comprising:
- a body having a reservoir disposed therein for containing a medicament;
- a rotor disposed in the body to move from a pre-activated position to an activated position to activate the device;
- 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 for covering the injection needle and preventing movement of the rotor to prevent device activation;
- wherein:
- the needle cover comprises a lockout pin engageable with the rotor through an opening in the device body to prevent device activation;
- the needle cover comprises a needle cover clip rotatably disposed on a needle-covering portion;
- and
- the lockout pin is disposed on the needle cover clip.
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;
- 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;
- and
- a rotor disposed in the body to move from a pre-activated position to an activated position to activate the device;
- wherein:
- the second portion of the needle cover engages the rotor to prevent the rotor from moving to the activated position;
- the rotor has an engagement slot;
- the second portion of the needle cover comprises a lockout pin for engaging the engagement slot through an opening in the device body to prevent device activation;
- the second portion of the needle cover comprises a needle cover clip rotatably disposed on the first portion of the needle cover;
- and
- the lockout pin is disposed on the needle cover clip.
