Abstract
A system and method for a patch-like, self-contained substance infusion device which provides one or more substantially hidden patient needles which can be placed in fluid communication with a fluid reservoir, wherein the device can be attached to a skin surface via an adhesive contact surface and a push button activation assembly can then be used to remove an interlock, allowing a disk, or Belleville spring assembly to apply an essentially even and constant pressure to the contents of the fluid reservoir, allow the release of the patient needles into the skin surface, and establish a fluid communication path between the patient needles and the pressurized fluid reservoir contents. The push button activation assembly further allows the release of one or more improved safety mechanisms after use.
