| 摘要 |
This invention is a fluid delivery device (20) having a self-contained stored energy membrane (34) for defining in conjunction with a base (22) a fluid delivery reservoir (30), and for expelling fluids from the reservoir (30). The device (20) includes novel reservoir filling syringe (68), and filling adapter (64) for conveniently filling the fluid reservoir (30) of the device (20). Additionally, the device (20) includes a unique crushable or collapsible needle cover (50) which surrounds and protects the infusion cannula (44) until time of use and then readily deforms as the device (20) is connected to the patient so as to permit the needle (44) to cleanly penetrate the patient's skin. The needle cover (52) maintains the cannula (44) in a substantially aseptic condition and enables self-administration by patients, such as young patients or needle adverse patients, which does not require their consciously inserting a needle into the skin.
