摘要： An apparatus for accurately infusing fluids into a patient at specific rates over an extended period of time and the method for making same. The apparatus includes one or more dispensers of a low profile, laminate or layered construction each having a stored energy source in the form of a distendable membrane or an elastomeric cellular mass, which in cooperation with the base, defined a fluid chamber having a fluid inlet and a fluid outlet. The apparatus further includes, in lieu of a rigid ullage, a high novel, conformable ullage made of yieldable materials. The conformable ullage uniquely conforms to the shape of elastomeric membrane as the membrane returns to its less distended configuration. This arrangement will satisfy even the most stringent delivery tolerance requirements and will elegantly overcome the limitations of materials selection encountered in devices embodying the rigid ullage construction. Additionally, with the novel ullage construction, the ullage can be located either between the base and the fluid to be delivered, or alternatively, can be located between the elastomeric membrane and the fluid to be delivered. Further, a plurality of subreservoirs can be associated with a single ullage thereby making it possible to incorporate a wide variety of delivery profiles within a single device.

摘要： A fluid delivery device for infusing medicinal fluids having a self-contained stored energy membrane for expelling fluids at a precisely controlled rate. The device is of a compact, low profile, laminate construction so that it can conveniently be used for the fluids, such as insulin and the like, into an ambulatory patient at controlled rates over extended periods of time. Included within the device are various fluid flow control elements including a unique hydraulic fluid rate control system for ultra low flow delivery. Also included is a highly novel flow indictor for providing a positive indication of fluid flow from the device and for indicating at any given time the amount of fluid remaining in the device.
