Publication number: 20030032940Abstract: A male luer connector device that attaches to any standard female luer valve to open a flow channel between the two luers. The male luer is comprised of a tubular housing element, a resilient member contained within the housing and extending within an inner tubular portion defined in the housing, a resilient member that extends within the inner tubular portion of the housing, and a valve member attached to the resilient member that seals the tubular portion. When the male luer is engaged with any standard female luer, a female luer connector device drives the resilient member of the male luer into a compressed position to open the forward end of the male luer and permit liquid flow between the luers.Type: ApplicationFiled: August 10, 2001Publication date: February 13, 2003Inventor: Mark C. Doyle

Patent number: 5700245Abstract: The present invention relates to apparatus and method for the controlled delivery of fluid. The apparatus comprises chemical reactants which combine to generate gas and create pressure to drive a fluid from a container. The reactants and the environment in which the reaction occurs are controlled, thereby causing the fluid to be delivered from the device at a predetermined flow rate.Type: GrantFiled: July 13, 1995Date of Patent: December 23, 1997Assignee: Winfield MedicalInventors: Gregory E. Sancoff, Mark C. Doyle, Frederic P. Field

Patent number: 5588556Abstract: The present invention relates to chemical reactants, compositions, methods to manufacture reactants, and apparatus for the generation of a gas pressure to drive a fluid from an infusion pump at controlled flow rates.Type: GrantFiled: June 5, 1995Date of Patent: December 31, 1996Assignee: River Medical, Inc.Inventors: Gregory E. Sancoff, Mark C. Doyle, Frederic P. Field

Patent number: 5578005Abstract: We disclose apparatus and methods for delivering for patient infusion or other use two or more fluids either sequentially or simultaneously. The apparatus has a fluid delivery compartment containing a first infusion fluid, a flexible membrane, and an openable bag containing a second infusion fluid. An attached gas reaction compartment contains chemical reactants which, when combined, react to evolve gas. The gas expands a gas expansion chamber causing the membrane to move into the fluid delivery compartment, displacing the first infusion fluid. The membrane eventually contacts and compresses the openable bag. Pressure from the membrane causes the bag to open and discharge its contents out of the infusion device.Type: GrantFiled: September 16, 1994Date of Patent: November 26, 1996Assignee: River Medical, Inc.Inventors: Gregory E. Sancoff, Mark C. Doyle, Frederic P. Field

Patent number: 5571261Abstract: A liquid dispensing device and the method of dispensing liquid are disclosed. The device includes a hollow gas- and liquid-tight casing, a flexible gas- and liquid-tight membrane having multiple convolutions disposed across the casing interior and dividing the interior into a propellant chamber and a liquid chamber, an outlet port from the liquid chamber. A pressure relief valve, suitable for use with the device, allows gas to escape from the device when the gas pressure exceeds a predetermined level.Type: GrantFiled: August 5, 1994Date of Patent: November 5, 1996Assignee: River Medical, IncInventors: Gregory E. Sancoff, Mark C. Doyle, Frederic P. Field

Patent number: 5558255Abstract: A liquid dispensing device and the method of dispensing liquid are disclosed. The device is uniquely suited to meet the requirements of hospitals and other institutions for long shelf life in inert condition and ready activation when needed. The device includes a hollow gas- and liquid-tight casing (preferably spherical or cylindrical), a flexible gas- and liquid-tight membrane disposed entirely across the casing interior dividing the interior into a propellant chamber and a liquid chamber; an outlet port from the liquid chamber; two mutually reactive chemicals in the propellant chamber but separated by a barrier; and a member to breach the barrier and permit the chemicals to come into contact; the two chemicals being reactive upon contact to form a propellant gas. The propellant gas thereupon expands against the membrane, moves the membrane to enlarge the propellant chamber, decrease the liquid chamber, and expel the contained liquid from the liquid chamber through the outlet port.Type: GrantFiled: June 5, 1995Date of Patent: September 24, 1996Assignee: River Medical, Inc.Inventors: Gregory E. Sancoff, Mark C. Doyle, Frederic P. Field

Patent number: 5397303Abstract: A device is disclosed which provides direct and effective incorporation of material (such as medicine) from a separate container into the contents of a liquid dispensing device. The device has a hollow sleeve extending outwardly, an openable closure, a securing member which engages a mating member on the container, and a conduit (such as a needle) to provide fluid communication between the device and the container, with the fluid communication occurring upon attachment of the container to the device. The device can also provide for attaching the separate container to the dispensing device but without initially establishing liquid communication between the two.Type: GrantFiled: August 6, 1993Date of Patent: March 14, 1995Assignee: River Medical, Inc.Inventors: Gregory E.

Patent number: 4968379Abstract: Apparatus for uniformly wetting a curvilinear surface of a length of tubing with solvent or other liquid. A wetting element such as a block of porous material has a curvilinear portion with a shape complemental to the shape of the surface to be wetted. The liquid is supplied to the wetting element by capillary action through a porous block or a sponge and passes into and through the wetting element, wetting the curvilinear portion. When the tubing to be wetted is brought into close contact with the curvilinear protein, the liquid is transferred to the tubing, forming a uniform coating on the surface thereof. Compressed air may be applied to the liquid through a pulse valve to urge the liquid into the wetting element as needed to re-wet the wetting element.Type: GrantFiled: May 25, 1988Date of Patent: November 6, 1990Assignee: Pacific Device, Inc.Inventor: Mark C. Doyle
