  • Patent number: 7217253
    Abstract: A device and two-step sequential method for providing medication for injection and infusion by a jet injector includes a cassette which connects an injector system to a reservoir. The cassette forms a fluid pathway at an interface of a cassette lower body and a cassette upper body. The cassette also forms an impulse chamber with a nozzle leading therefrom. The fluid pathway interconnects the reservoir with the impulse chamber. The medication flows from the reservoir along the fluid pathway and into the impulse chamber. Force from an impulse generator drives the fluid medicament from the impulse chamber through the nozzle, out an orifice in a tip of the nozzle, and into the skin of a patient. To prevent the pressure waves generated by the jet injector from damaging a glass reservoir, the fluid pathway is formed with pressure attenuators.

  • Publication number: 20050020969
    Abstract: An integral data logging system for a jet injector includes at least one electrical switch that changes state (e.g. from OFF to ON) during an injection procedure. The switch(es) are connected to an electrical circuit having a microprocessor, a clock and an electronic memory. When a switch changes state, this information along with the applicable date and time is recorded in the electronic memory. A communications link is provided to upload the stored data to a remote computer for subsequent manipulation and analysis to determine compliance with a prescribed dosing regimen. In one implementation, the injection duration is logged by using a trigger release switch and an end-of-stroke switch. The end-of-stroke switch is configured to change state after the drive bar of the injector transits through the injector tube. The injection duration is indicative of dose amount and can be used to distinguish between valid and invalid injections.

  • Publication number: 20040106895
    Abstract: An injector for injecting a fluid medicament includes an injector body, a medicament chamber and a plunger that can be advanced into the chamber to expel medicament from the distal end of the chamber. An air-in-tip mechanism is provided within the injector body for partially withdrawing the plunger from the chamber to create an air pocket in the chamber adjacent the distal end. The air-in-tip mechanism includes a gripper ring that is positioned within the injector body and initially oriented to allow the plunger to move freely through the gripper ring. A user operable button is attached to the gripper ring to first tilt the gripper ring until it engages the plunger and then move the plunger proximally to create the air pocket. Alternatively, a face cam and push rod assembly can be activated when the injector's locking nut is turned to automatically tilt and move the gripper ring.

  • Publication number: 20040042930
    Abstract: The present invention relates to a reaction chamber for use in processing liquid samples, particularly liquid specimens from medical patients. The reaction chamber of the present invention comprises a primary chamber and a capillary channel located at each of an inlet and an outlet of the primary chamber. The reaction chamber also has a capillary lock feature associated with it. The capillary lock feature positions the liquid specimen in the primary chamber and the capillary channels and retains the liquid sample therein. The reaction chamber of the present invention may be employed in a cartridge or other device that processes such liquid samples.

  • Patent number: 6669664
    Abstract: A vacuum control system for a jet injector includes a power source and vacuum pump for creating suction at the injector tip. The injector includes a drive bar to expel medicament into the patient. Before injection the drive bar and an inner barrel are separated from each other, and at the end of the injection the drive bar contacts the inner barrel. A user operable switch that is moveable between an ON position and an OFF position is also provided. The power source, vacuum pump, drive bar, inner barrel and user operable switch are all electrically connected via an electrical circuit. The electrical circuit is configured to activate the vacuum pump when the user operable switch is in the ON position and the drive bar is separated from the inner barrel, and to deactivate the vacuum pump when the drive bar contacts the inner barrel.

  • Patent number: 6645169
    Abstract: A method for injecting a fluid medicament into a patient uses a syringe having a plunger that can be advanced into the syringe chamber. As the plunger is advanced, the medicament is expelled from the chamber through an injection tube that extends from the chamber. Preferably, the injection tube is formed as a cone-shaped funnel with a taper of generally decreasing radius in a distal direction. The steps for the method include creating a gas pocket in the distal portion of the injection tube. Then, as the plunger is advanced into the chamber to accelerate the fluid medicament through the injection tube, the gas pocket allows the accelerating fluid medicament to gain momentum. The change in this momentum as the fluid medicament collides with the skin will generate an impulse force that is manifested as an initial pressure spike. This pressure spike creates a hole in the skin of the patient as the fluid medicament exits the tube.

  • Patent number: 6440110
    Abstract: An apparatus and method for collecting a large volume of blood from an umbilical cord in a sterile environment are shown and described. A housing having an inner region adapted to retain an umbilical cord in a desired location is provided, the housing having an opening through which the cord extends from the inner region of the housing to a region external to the housing. The cord is cut by a blade coupled to the housing, either by the motion of the blade from a first position to a second position, or by the movement of two portions of the housing from a first extended position to a second collapsed position. The newly cut end of the umbilical cord falls and hangs freely in the inner region of the housing, blood flowing from the placenta and umbilical cord via gravity into a blood collection region of the housing. The blood collection region may be flexible, and may be coupled to a conventional blood collection bag.

  • Patent number: 6406456
    Abstract: An injector for the intra-muscular, subcutaneous, or intra-dermal delivery of a fluid medicament to a patient includes a cylindrical member which has a closed end and an open end, and which is formed with a compartment between these two ends. An injection tube extends from the closed end through the cylindrical member and into the compartment. A suction pump is connected in fluid communication with the compartment to create a partial vacuum in the compartment when the open end of the cylindrical member is held against the skin of the patient. Due to this vacuum, skin of the patient is drawn into the compartment to position the tip of the injection tube against the skin. Also, skin that is adjacent the tip is drawn by the vacuum into the compartment. This stabilizes the skin around the injection tube tip and thereby minimizes any movement of skin relative to the tip during an injection of fluid medicament into the patient.

  • Patent number: 6293436
    Abstract: A liquid dispensing container of the squeeze bottle type has a low center of gravity liquid bottle with a hemispherical base portion and a frusto-conical neck portion. A spout assembly is coupled to an upper end of the neck portion for dispensing liquid when a deformable bottom wall of the base portion of the bottle is flexed. The spout assembly includes a bottle cap with a through bore in which a flexible dispensing tube is slidably extensible and retractable to dispense liquid, such as lubricating oil, into locations that would otherwise be inaccessible. A wiper element in the bottle cap associated with the through bore provides a liquid impervious seal between the bottle cap and the tube and ensures that excess liquid on the outer surface of the tube is scraped off as the tube is extended. A nozzle is connected to a distal end of the tube and a pop-up sealing cap is slidable back and forth over the nozzle to selectively open and close a dispensing hole in the pop-up cap.
