A system and method for a patch-like, self-contained substance infusion device which can be attached to a skin surface via an adhesive contact surface. 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 a fluid reservoir assembly. This allows the release of one or more spring-loaded patient needles into the skin surface, and establishes a fluid communication path between the patient needles and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button activation assembly further allows the release of one or more improved safety mechanisms after use.

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.

A one-piece low drag septum is provided for preventing escape of fluid from an introducer needle during removal of such a needle from a catheter and introducer needle assembly. The septum generally includes a distal portion, a proximal portion, a cavity portion, and a longitudinal axis. The distal portion acts as a primary seal to prevent escape of blood from the catheter into the assembly and is generally positioned furthest away from the user of the apparatus and nearest the patient. The cavity portion reduces friction placed on the introducer needle. The proximal portion of the septum acts as a secondary seal to prevent escape of material from the cavity, seals the cavity, and wipes the needle as it is being withdrawn from the catheter assembly.
