초록 ▼

A system and method for a patch-like, self-contained substance infusion device (700) which can be attached to a skin surface via an adhesive contact surface. A push button (780) activation assembly can then be used to remove an interlock (730), allowing a disk or Belleville spring (735) assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly (710). This allows the release of one or more spring-loaded patient needles (760) into the skin surface, and establishes a fluid communication path between the patient needles (760) and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button (780) activation assembly further allows the release of one or more improved safety mechanisms (794) after use.

1. A device for delivering a medicament into a body of a patient by injection into or through a skin surface of the patient, comprising: a housing having an aperture and being adhesively securable to a skin surface of a patient;a needle holder having at least one needle adapted for penetration of the skin surface and for movement through the housing aperture;a reservoir, disposed within the housing, for containing the medicament;an activation button disposed on the device and adapted to actuate the device; anda biased shielding member configured to be held in place prior to device actuation, the shielding member comprising a ramp configured to directly contact and raise the needle holder to retract the needle into the device, the shielding member being adapted to at least partially cover at least one of the needle and the housing aperture. 2. The device as claimed in claim 1, wherein the ramp is configured to slidably cover the needle or the housing aperture. 3. The device according to claim 1, wherein the shield is biased to move substantially parallel to a bottom surface of the housing in which the aperture is disposed. 4. A device for delivering a medicament into a body of a patient by injection into or through a skin surface of the patient, comprising: a housing having a bottom surface with an aperture and being adhesively securable to a skin surface of a patient;an actuation button slidably disposed on the device;a needle holder having at least one needle adapted for penetration of the skin surface and for movement through the housing aperture; anda shielding member configured to be held in place prior to actuation of the device, the shielding member being urged to move substantially parallel to the bottom surface of the housing into a position to at least partially cover at least one of the needle and the housing aperture;wherein the shielding member comprises a ramp configured to contact and raise the needle holder to retract the needle into the device. 5. The device as claimed in claim 4, wherein the ramp is configured to slidably cover the needle or the housing aperture. 6. A device for delivering a medicament into a body of a patient by injection into or through a skin surface of the patient, comprising: a housing having an aperture and being adhesively securable to a skin surface of a patient;an actuation button slidably disposed on the device;a needle holder having at least one needle adapted for penetration of the skin surface and for movement through the housing aperture; anda shielding member configured to be held in place prior to actuation of the device, the shielding member being urged to move substantially parallel to the housing into a position to at least partially cover at least one of the needle and the housing aperture;wherein the shielding member comprises a ramp configured to contact and raise the needle holder to retract the needle into the device;wherein the ramp is configured to slidably cover the needle or the housing aperture.
