Abstract
A device (100) for delivering a medicament into a patient'"'"'s body by injection into or through the patient'"'"'s skin, including: a main body having a bottom enclosure (104) that has a top surface including a button guide latch (268); a reservoir (160) disposed within the main body for containing the medicament; an injection needle (152) for penetrating the skin of the patient, the needle (152) having a lumen and communicating with the reservoir (160) when the device (100) is activated; a pressurizing system (140, 144) for pressurizing the reservoir (160) when the device (100) is activated; and an activator button (128) movably disposed on the main body and movable from a pre-activated position to an activated position. The activator button (128) includes an activation arm (228). When the activator button (128) moves from the pre-activated position to the activated position, an end of the activation arm (228) engages with the button guide latch (268) and prevents return movement of the activator button (128).

17. A drug delivery device comprising:
-
a body including a top enclosure and a bottom enclosure, the bottom enclosure having a surface including a button guide latch having a guide surface and a retaining surface; a reservoir disposed within the body forming a chamber for containing the medicament; an injection needle for penetrating the skin of the patient, the needle having a lumen and communicating with the reservoir when the device is activated; a pressurizing system for pressurizing the reservoir when the device is activated; and an activator button movably disposed on the body and movable from a pre-activated position to an activated position, the activator button including an activation arm with a cutout and a locking portion having a bearing surface and a locking surface; wherein when the activator button is moved from the pre-activated position to the activated position; the bearing surface contacts and slides along the guide surface of the button guide latch, elastically deforming at least one of the activation arm and the guide surface until an end of the guide surface is reached; and the cutout permits the activation arm to pass over the end of the guide surface, engaging the locking surface with the retaining surface of the button guide latch to prevent return movement of the activator button. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A drug delivery device comprising:
-
a body including a top enclosure and a bottom enclosure, the bottom enclosure having a surface including a button guide latch; a reservoir disposed within the body for containing the medicament; an injection needle for penetrating the skin of the patient, the needle having a lumen and selectively communicating with the reservoir; a pressurizing system for pressurizing the reservoir; and an activator button movably disposed on the main body and movable from a pre-activated position to an activated position, the activator button including an activation arm; wherein when the activator button is moved from the pre-activated position to the activated position, an end of the activation arm engages with the button guide latch and prevents return movement of the activator button; and wherein movement of the activator button from the pre-activated position to the activated position performs at least one function selected from the group of driving the injection needle to penetrate the patient'"'"'s skin, pressurizing the reservoir, and establishing fluid communication between the reservoir and the patient needle.
