摘要 |
A system and method for a patch-like, self-contained substance infusion device (1000) which provides one or more substantially hidden patient needles (222) which can be placed in fluid communication with a fluid reservoir subassembly (100) that includes a rigid bladder portion (120) used in conjunction with a non-distensible bladder film (170), such as a metallized film. Simple removal of an interlock allows a disk (130), or Belleville spring assembly to apply an essentially even and constant pressure to the contents of the fluid reservoir assembly, and allows the device to then be attached to a skin surface via an adhesive contact surface. A push button activation assembly (300) is provided which can then be used to release and seat one or more spring-loaded patient needles into the skin surface, and establish a fluid communication path between the patient needles and the pressurized fluid reservoir contents thereby delivering an infusion into the skin.
