  • Patent number: 6436084
    Abstract: Implantable ports and other devices are disinfected by the injection of an anti-microbial agent into a region in the device or in a tissue pocket surrounding the device. In a first embodiment, the anti-microbial agent is injected through an aperture in the device to flush internal regions of the device before infusing the tissue pocket and flushing outwardly through a tissue tract leading to the device. In other embodiments, the anti-microbial agent is injected directly to a target site on the exterior of the device. Implantable devices may include special, usually hardened, target regions for receiving the sharpened end of a needle used to inject the anti-microbial agent. Kits will include devices, syringes, access devices, and instructions for disinfection according to the methods of the present invention.

  • Patent number: 6416497
    Abstract: The needle protection holder encloses an automatically retractable safety syringe and needle within a tubular cylinder after the needle has been used. Its intended purpose is to remove a needle attached to a syringe from a patient, both human and animal, thereby containing the needle safely within the holder or cylinder. With such a construction, the holder prevents the exchange of bodily fluids caused by needle sticks which are known to cause serious illnesses including death to medical technicians and personnel.

  • Patent number: 6391005
    Abstract: An apparatus having a shaft that can sense the depth of penetration, for penetrating into an object (the substrate). The substrate being penetrated has impedance that varies according to the depth under a surface of the substrate. The shaft has a tip for penetration and has conductive ends near to the tip of the shaft. A change of impedance of material of the object between the conductive ends can be sensed to provide information on the depth of penetration. A processor can be provided external to the object being penetrated by the shaft to gather and process the impedance information to determine whether the desired depth has been achieved.

  • Patent number: 6387069
    Abstract: An extracorporeal blood set may be primed with physiological solution for use in a blood transporting process such as hemodialysis. The set comprises tubing having a patient connector on an end thereof, and a first branch tube in connection with a source of the solution. The branch tube connects with the set between the ends of the set. The branch tube also connects with further branch tubing, having a second connector which is capable of sealing connection with the patient connector. The method comprises the steps of connecting the patient connector and the second connector to form a closed loop of tubing. One then passes the solution from the source in flow through the first branch tube and further branch tubing to fill them and the set tubing with the solution. One then disconnects the patient connector for subsequent connection with the vascular system of a patient.

  • Patent number: 6379342
    Abstract: An ampoule which has been designed to contain sterile medicinal fluids of various types and doses in a measured dose fashion, which allows direct administration via linkage to standardized existing indwelling catheters, tubing and even hypodermic needle hubs by virtue of a contained Luer Lock fitting. The invention eliminates the need to draw up fluids into intermediary devices such as needles and syringes or other injection devices, thus minimizing costs and enhancing safety and convenience. The ampoule, by virtue of finger pressure on its flexible structure, allows complete administration directly into the body or its structures. The contents of the ampoule are protected and the sterility of contents and linkage mechanism is protected by a cover which occludes the opening into the ampoule until use. The ampoule also allows direct administration by connection of its Luer Lock fitting to standard hypodermic needles and hubs for injection into or through body structures.

  • Patent number: 6379336
    Abstract: A protective device for injection or aspiration needles has a barrel piece telescopically slidable over an adapter sleeve mounted at one end to the luer coupling of the syringe or to a multisample collector. An injection needle is mounted within the adapter sleeve, projecting out through an opening in the opposite nose end of the barrel piece. An interposed spring urges the adapter sleeve and barrel piece apart towards a fully extended position. The barrel piece and adapter sleeve are latched together in a ready to use position with the needle partially protruding out from the barrel piece. As the syringe or multisampling system is advanced, the needle is extended out through the barrel piece end to allow penetration into the patient's body, and automatic unlatching is induced as penetration begins.

  • Patent number: 6364866
    Abstract: A syringe loading device is disclosed that includes a vial holder, a syringe insertion guide and holder, a transparent cover mounted to the vial holder and syringe insertion guide and holder, and an ejection button. The vial holder is adapted to hold a vial containing liquid contents and has an integrated interference snap fit to removably receive a cap of the vial. The syringe insertion guide and holder, which is placed adjacent the vial holder and integrated therewith, is adapted to allow a syringe having a needle at one end to be removably inserted, needle end first, into the syringe insertion guide and holder with the needle penetrating into the vial. The syringe insertion guide and holder also has biased syringe clamps that hold the body of the syringe in a removably fixed position. The transparent cover slidably mounts parallel to the vial holder and syringe insertion guide and holder to protect the vial and syringe when placed in the syringe holder.
