FLUID DELIVERY DEVICE WITH TEMPERATURE CONTROLLED ENERGY SOURCE

摘要

A fluid delivery apparatus (50) for infusing medicinal fluids into a patient which is of a compact, low profile, fluid storage device (52), laminate construction, with a cooperating and remotely located infusion means (54) for infusing the medicinal fluid (F) into the patient. The apparatus embodies a novel thermal expanding polymer material (70) which uniquely functions as an internal energy source for expelling the medicinal fluids from the device. The apparatus can be used for subdermal, intradermal and intramuscular infusion of fluids and in one form of the invention, includes a novel delivery cannula having a body portion disposed within a circuitous channel (108) formed within the base (56) of the apparatus and a pierceable portion (100d) which extends outwardly from the base of the apparatus.
