  • Patent number: 7828772
    Abstract: A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as antibiotics, blood clotting agents, analgesics, and like medicinal agents from collapsible containers at a uniform rate. The dispenser includes a novel stored energy source that is provided in the form of a compressible-expandable member that functions to continuously and uniformly expel fluid from the device reservoir. The apparatus further includes a novel fluid flow control assembly that precisely controls the flow of the medicament solutions from the device reservoir to the patient.

  • Patent number: 7789853
    Abstract: A fluid dispenser for use in controllably dispensing fluid medicaments, such as antibiotics, oncolytics, hormones, steroids, blood clotting agents, analgesics, bio-pharmaceuticals and like medicinal agents from a reservoir that has been filled from pre-filled containers. The fluid dispenser includes a housing to which fill-vials can be connected for filling the dispenser reservoir with the fluid, and a stored energy source provided in the form of a substantially constant-force spring that provides the force necessary to continuously and uniformly expel fluid from the device reservoir. The fluid dispenser also includes a fluid flow control assembly that precisely controls the flow of the medicament solution to the patient.

  • Patent number: 7735522
    Abstract: A flow control device that is uniquely capable of providing uniform flow under changing environmental conditions of temperature and pressure. The device achieves flow rate stabilization by taking advantage of the properties of the moving fluid in a channel with eddy currents that are generated as fluid moves past obstacles located in the fluid flow path. The shape and magnitude of such eddies depend on the viscosity of the fluid. Additionally, the device can also simultaneously stabilize the fluid flow rate under varying pressure by using a strategically positioned, yieldably deformable elastomeric membrane. Therefore, the invention uniquely combines two devices into one novel fluidic device that can stabilize a flow rate under simultaneously changing temperatures and pressures.

  • Patent number: 7694938
    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.

  • Patent number: 7513273
    Abstract: A flow control device having no moving parts that controls fluid flow along a fluid pathway in such a way that flow rate remains constant irregardless of environmental changes. The device achieves a constant flow rate by taking advantage of the properties of the fluid moving along the fluid pathway and maintains the constant flow rate irregardless of changes in viscosity due to changes in temperature.

  • Patent number: 7481244
    Abstract: A flow control device of the character having a fluid pathway for permitting fluid flow therealong under conditions of varying temperature and pressure for achieving substantially constant output flow rate from the fluid pathway. One or more flexibly deformable vanes, which extend into the fluid pathway, are constructed and arranged to flexibly deform in a manner to further occlude the fluid pathway when the pressure within said fluid path way increases.
