ABSTRACT:
A fluid delivery device having a self-contained stored energy membrane for defining in conjunction with a base a fluid reservoir and for expelling fluids from the reservoir. The device includes novel reservoir filling syringe and filling adapter for conveniently filling the fluid reservoir of the device. Additionally, the device includes a unique crushable or collapsible needle cover which surrounds and protects the infusion cannula until time of use and then readily deforms as the device is connected to the patient so as to permit the needle to cleanly penetrate the patient's skin. The needle cover maintains the cannula 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.
