摘要:
Embodiments of the invention are directed to flush syringe assemblies comprising an integrated contamination-prevention device integrated with device connector flushing positioned so that the practitioner cannot forget to apply disinfectant. The flush syringe assemblies comprise a barrel with an elongate plunger rod disposed therein and a cap comprising a passageway. The plunger rod includes a stopper of which at least a portion can be embedded in the passageway of the cap to form a plug in the cap.

An apparatus may include a needle for sustained delivery of drugs and other agents to the inner ear or other tissues of a human or an animal. The needle can include an insertion stop, and can be placed through the round window membrane or through a surgically-prepared hole in a bone. The needle can be in fluid communication with a port and/or with a micro-infusion or osmotic pump. A cochlear implant electrode can be used instead of a needle.

Die Erfindung betrifft eine Infektionsschutzvorrichtung für Endoexo-Implantate 1 gekennzeichnet durch eine schlauchförmige Schutzmembran 2, die aus dem sterilen Bereich des Körperinneren heraus in den unsterilen Außenbereich bewegt wird und so an der Hautdurchtrittsstelle 6 eine Wandbewegung von innen nach außen erzeugt, die das gegenläufige Eindringen von Mikroben verhindert.
摘要:
An infection-prone living body site may be rendered substantially sterile by sealing a bacteria-resistant enclosure (10) about the body site and passing gas into the enclosure for bacteriocidal or bacteriostatic effect. Apertures (24, 26) having bacteria filters (28) are used for gas entry and exit.
摘要:
The present invention relates to subcutaneously implanted graft-port systems, devices and methods for establishing access to the vascular system of a patient requiring multiple blood treatments over an extended period of time. The systems, devices and methods disclosed herein reduce miscannulation, promote intra-session hemostasis, and decrease the incidence of bacteremia and sepsis among other improvements and advantages. The devices include a port with a flattened plateau-like surface for receiving an access tube. The flat surface may include a tactile or visual guide to assist with placement of the access tube into the tapered seat. Optional valve mechanisms reduce the size and form factor of the implantable graft-port device and seals the conduit of the port closed to physiologic pressures until the valve is opened upon percutaneous insertion of the access tube. The access tube does not pass into the conduit. A mismatch fit between the access tube and tapered seat causes a decrease in the cross-sectional sealing area, a reduction in the overall device size, and an increase in blood flow during treatment. Lock solutions to prevent fowling and infection are also disclosed.
