Abstract

An apparatus for accurately infusing large volumes of fluids into a patient at specific rates over an extended periods of time. The apparatus includes one or more dispensers of a low profile, laminate or layered construction each having a stored energy source in the form of a distendable membrane or an elastomeric cellular mass, which in cooperation with a base, defines a fluid chamber having a fluid inlet and a fluid outlet. The apparatus further includes a support for supporting the dispensers in a coupled relationship with a manifold system which has an outlet to which an administration set can be connected. In one form of the invention, the apparatus also includes a filling vial assembly that can be coupled with the dispensers to fill the fluid chambers thereof with the fluids to be infused.
