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).

15. A 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 a medicament; a 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; 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; a channel fluidly connected to the needle; a valve disposed between the reservoir and the channel to selectively permit delivery of the medicament from the reservoir to the channel; a drive spring movable from a pre-activated position to an activated position; and a rotor movable between a pre-activated position and an activated position, the rotor supporting the drive spring in the respective pre-activated positions of the rotor and the drive spring; 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 movement of the activator button from the activated position to the pre-activated position wherein the bottom enclosure includes a bottom surface for contacting the skin of the patient and the surface of the bottom enclosure includes a substantially cylindrical housing about which the rotor is rotatably disposed, the pressurizing system being disposed within the cylindrical housing; and when the activator button is moved from the pre-activated position to the activated position, the activation arm moves the rotor to the activated position, thereby releasing the pressurizing system to pressurize the reservoir and releasing the drive spring to move to the activated position to drive the needle to penetrate the skin of the patient, and the activator button opens the valve to permit delivery of the medicament from the reservoir to the needle via the channel. - View Dependent Claims (16)

17. A device, comprising:
-
a body including a top enclosure and a bottom enclosure not movable relative to the top 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 a medicament; a 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 to rotate relative to the top enclosure, 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. A 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 a medicament; a 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; wherein the device further comprises; a channel fluidly connected to the needle; a valve disposed between the reservoir and the channel to selectively permit delivery of the medicament from the reservoir to the channel; a drive spring movable from a pre-activated position to an activated position; and a rotor movable between a pre-activated position and an activated position, the rotor supporting the drive spring in the respective pre-activated positions of the rotor and the drive spring; wherein the bottom enclosure includes a bottom surface for contacting the skin of the patient and the surface of the bottom enclosure includes a substantially cylindrical housing about which the rotor is rotatably disposed, the pressurizing system being disposed within the cylindrical housing; and when the activator button is moved from the pre-activated position to the activated position, the activation arm moves the rotor to the activated position, thereby releasing the pressurizing system to pressurize the reservoir and releasing the drive spring to move to the activated position to drive the needle to penetrate the skin of the patient, and the activator button opens the valve to permit delivery of the medicament from the reservoir to the needle via the channel. - View Dependent Claims (24)
