  • Patent number: 6394980
    Abstract: 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 distendable membrane, chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet. The apparatus also includes a highly novel fluid flow indicator that provides a readily discernible visible indication of fluid flow through the apparatus. Additionally, the apparatus includes a fill assembly comprising a prefilled vial that can be used to fill the fluid reservoir of the device with a selected medicinal fluid.
    Type: Grant

  • Publication number: 20010039397
    Abstract: An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus includes a housing having a delivery outlet and an elastic distendable membrane for defining a chamber within the housing. Also provided is a flow rate control assembly delivery outlet. The apparatus further includes a mechanism for quickly and easily priming the fluid flow passageways of the fluid delivery component. Additionally, the apparatus includes a novel fluid flow indicator that provides a readily discernible visible indication of fluid flow through the apparatus. Further provided is a fill assembly for filling the fluid reservoir of the device with a selected medicinal fluid and locking mechanisms for preventing unauthorized tampering with the flow rate control mechanism as well as the priming mechanism.
