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. 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 novel adjustable flow rate control means for precisely adjustably controlling the rate of fluid flow from the reservoir of the device.

Variable rate infusion apparatus with indicator and adjustable rate control

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.

Fluid delivery apparatus with flow indicator and vial fill

An elastomeric bladder stored energy type infusion apparatus that can be filled with a medicinal fluid and, after being filled, can efficiently delivery the medicinal fluid to the patient at a selected rate. The apparatus includes a delivery component for delivering medicinal fluid to the patient and a fill component that can expeditiously be used to fill the fluid reservoir of the delivery component in the field.

Fluid delivery apparatus with reservoir fill assembly

An apparatus for delivering fluids at a precisely controlled rate which includes a fluid dispensing component having a fluid reservoir for containing the fluids to be delivered and a reservoir fill component which can be removably interconnected with the fluid dispensing component. The reservoir fill assembly is uniquely designed to accept a vial component of conventional construction which is factory filled with the medicinal fluid to be delivered to the patient. The dispenser component embodies a highly novel fluid flow indicator that provides a readily discernible visual indication of fluid flow status through the device.

An apparatus for delivering fluids at a precisely controlled rate which comprises a fluid dispensing component having a fluid reservoir for containing the fluids to be delivered and a reservoir fill component which can be removably interconnected with the fluid dispensing component. The dispensing component can be used for the precise infusion of pharmaceutical fluids to an ambulatory patient at controlled rates. The reservoir fill assembly is uniquely designed to accept a vial component of conventional construction which is partially received within a novel adapter subassembly that can readily be removably interconnected with the fluid dispensing component.

An apparatus for visually indicating fluid flow through a fluid system or apparatus such as a medical infusion device. The apparatus comprises a pair of thin, indicia bearing films disposed in an overlaying relationship. These films are shifted relative to each other by movement of mechanical actuators which are deflected solely by the pressure of the fluid within the fluid conduits of the system of the apparatus. The two films are stacked in closed proximity and are preferably constructed from a substantially transparent flexible material such as mylar. One surface of the inferior film is printed with a plurality of integrated symbols depicting various fluid flow conditions. The superior film functions as a mask over the inferior film and is printed with a pattern of diagonally extending, alternating clear and opaque stripes. The print ratio of the superior film permits viewing at any one time of only one of the symbols printed on the inferior film.
