Abstract: An apparatus for delivering fluids at precisely controlled rates to ambulatory patients. The invention comprises a housing having a fluid reservoir to contain fluids to be delivered to the patient, a novel stored energy membrane for expelling fluid from the reservoir and a unique flow control assembly in communication with the fluid reservoir for the precise infusion of pharmaceutical fluids to ambulatory patients at precisely controlled rates. The flow control assembly includes a novel rate control member having a plurality of fluidic micro-channels through which the fluid is selectively directed.

Abstract: A dual reservoir fluid dispensing apparatus for use in controllably dispensing fluid medicaments, such as antibiotics, analgesics and like medicinal agents from either or both of the device reservoirs. The fluid dispensing apparatus includes novel fill means for selectively filling each of the reservoirs with the same or different medicaments that are to be dispensed to the patent. Stored energy sources are provided in the form of a pair of constant force spring members of novel design that provide the force necessary to continuously and substantially uniformly expel fluid from the reservoirs. The apparatus also includes novel adjustable flow rate assemblies that are disposed intermediate the outlet port of the fluid reservoirs and the outlet port of the device for precisely controlling the rate of fluid flow from the outlet port toward the patient.

Abstract: A distal rate control device, which can be conveniently interposed between a fluid supply line and fluid delivery line for precisely controlling the rate of fluid flow toward the delivery line. The device includes a readily adjustable flow rate control device having a novel flow control plate that can be placed in fluid communication with the fluid supply line and with the fluid delivery line. The flow control plate is provided with a plurality of elongated fluidic flow control channels that are in communication with a rate selector member that is rotatably carried by the device housing. Rotation of the rate selector member places a selected one of the flow control channels in communication with the fluid delivery line.

Abstract: A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as antibiotics, analgesics, and the like medicinal agents from the reservoir of the device. Uniquely, the dispenser includes a novel bellows-type reservoir and vial fill means for filling the bellows-type reservoir with the medicament to be dispensed. The dispenser also includes a novel stored energy source in the form of a constant force spring which controllably urges the medicinal fluid from the device reservoir. Additionally, the apparatus of the invention includes a novel adjustable flow rate control assembly that is disposed intermediate the fluid reservoir outlet and the outlet port of the device for precisely controlling the rate of fluid flow from the outlet port toward the patient.

Abstract: Nanofilms useful for filtration are prepared from amphiphilic species and one or more polymeric components. The amphiphilic species or components may be oriented on an interface or surface. A nanofilm may be prepared by coupling one or more of the components. The nanofilm may also be deposited or attached to a substrate.

Abstract: A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as, antibiotics, analgesics, and like medicinal agents from the device reservoir which is provided in the form of a novel bellows type assembly. The fluid dispenser includes a unique stored energy mechanism which takes the form of a constant force spring member of novel design that provides the force necessary to continuously and substantially uniformly expel fluid from the device reservoir. The device also includes novel adjustable flow rate control assembly that is disposed intermediate the fluid reservoir outlet and the outlet port of the device for precisely controlling the rate of fluid flow from the outlet port toward the patient.

Abstract: This invention is related to the fields of organic chemistry and nanotechnology. In particular, it relates to materials and methods for the preparation of organic synthons and bridged macrocyclic module compounds. The bridged macrocyclic module compounds may be used to prepare macrocyclic compositions such as nanofilms, which may be useful for filtration.
