<p>This invention is an apparatus (30) for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus (30) is of a compact, low profile, laminate construction, and includes an elastic distending membrane (34), a chamber (46) having a fluid outlet (52). Disposed within the fluid chamber (46) is a thin fluid permeable member (66) which precisely controls the rate of fluid flow through the fluid outlet (52). The apparatus (30) also includes a highly novel fluid flow indicator (100) that provides a readily discernible visible indication of fluid flow through the apparatus (30). Additionally, the apparatus (30) includes a fill assembly (150d) comprising a prefilled vial (170) that can be used to fill the fluid reservoir (46) of the device (30) with a selected medicinal fluid.</p> |
