<p>This invention is an apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes either an elastic distendable membrane (50), or a thin barrier member (16) which, in cooperation with a thin planar base (12) defines a fluid chamber (R) having a fluid outlet (28). The apparatus includes an internal stored energy source (18) which functions to controllably expel the medicinal agents from the apparatus. The stored energy source (18) may comprise either a distendable elastomeric membrane (50), or an expandable sponge-like cellular mass (18).</p> |
