<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 an elastic distensible membrane (40), chamber (50) having a fluid outlet (52). Disposed within the fluid chamber (50) is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet (52). The apparatus also includes a highly novel fluid flow indicator (36) that provides a readily discernible visible indication of fluid flow through the apparatus. Additionally, the apparatus includes a fill assembly (49) comprising a pre-filled vial that can be used to fill the fluid reservoir (50) of the device with a selected medicinal fluid.</p> |
