1. A drug delivery device comprising:
- a base member defining a skin-contacting surface for application to the skin of a subject;
a syringe serving as a reservoir for the drug and which is connected to the base member such that in use the longitudinal axis of the syringe is disposed substantially parallel to the skin-contacting surface;
a delivery needle in communication with the syringe, the needle having an angled bend which directs the tip of the needle substantially perpendicular to the skin-contacting surface such that in use the tip of the needle is adapted to penetrate the skin of the subject; and
means for expelling a drug out of the interior of the syringe.

Abstract
A drug delivery device having a base member defining a skin-contacting surface, a syringe serving as a reservoir for the drug, and means for expelling drug from the syringe. The syringe is connected to the base member such that the longitudinal axis of the syringe is substantially parallel to the skin surface. A delivery needle is in communication with the syringe. The needle has an angled bend which directs the tip of the needle substantially perpendicular to the skin-contacting surface. In use, the tip of the needle is adapted to penetrate the skin of the subject.

32. A method for manufacturing and filling a drug delivery device comprising:
-
providing a base member having a skin-contacting surface, a syringe having drug therein and which is connected to the base member such that in use the longitudinal axis of the syringe is disposed substantially parallel to the skin-contacting surface, a delivery needle in communication with the syringe, the needle having an angled bend which directs the tip of the needle substantially perpendicular to the skin-contacting surface such that in use the tip of the needle is adapted to penetrate the skin of the subject; and
means for expelling a drug out of the interior of the syringe,filling the syringe barrel with the drug under sterile conditions with the drug delivery path and the skin-contacting and skin-penetrating portions of the needle under sterile conditions and carrying out the remainder of the manufacturing and assembly steps in a clean area. - View Dependent Claims (33, 34, 35, 36)

37. A drug delivery device comprising:
-
a housing having an internal drug reservoir;
a drug delivery needle extending from the housing for penetration of the skin of a subject, the needle having an outlet for drug delivery;
a base member defining a skin-contacting surface for application to the skin of a subject, said base member being displaceable relative to the housing between a first position in which the needle is concealed from the exterior of the device and a second position in which the delivery needle protrudes from the device for penetration of the skin, the device further comprising means for locking the device in the first position after a single reciprocation of the device from the first position to the second position and back to the first position. - View Dependent Claims (38, 39, 40, 41, 42)

43. A method of delivering drug to a subject comprising the steps of:
-
providing a drug delivery device having a skin-contacting surface, a syringe having drug therein, and which is connected to the base member such that in use the longitudinal axis of the syringe is disposed substantially parallel to the skin contacting surface, a delivery needle in communication with the syringe, the needle having an angled bend, and means for expelling a drug out of the interior of the syringe;
applying the device to the skin of the subject; and
activating the device. - View Dependent Claims (44, 45, 46, 47, 48, 49)
