Abstract

A fluid delivery device for infusing medicinal fluids at a precisely controlled rate which includes adapter sleeve means for insuring that only a proper medicament can be used to fill the fluid reservoir of the apparatus. More particularly, the apparatus includes a unique polarity adapter that will mate only with a particular delivery device and positively prevent filling the reservoir of the device with a medicament that is incompatible with the delivery profile of the device. In one form of the invention, the polarity adapter includes a novel double-ended cannula that is carried within the polarity adapter and controls filling of the fluid reservoir.
