    摘要： A system and method is provided including a fluid communications network that sends priming and waste fluid to a waste bag, obviating the presence of open fluid containers in an operating room or catheter lab. The fluid communications network is constructed and arranged to allow nearly automated priming and bubble removal, thereby reducing the possibility of operator caused errors in set-up and reducing the time required for set-up. The fluid communications network is useable for attachment to a balloon catheter for inflation thereof. In order to provide greater control and automation of the inflation of the balloon catheter, a conversion kit is provided that can be used to convert an existing automatic injector into an injector useable for automatically controlling the small amount of injection fluid typically associated with balloon catheters.

    摘要： Implantable ports and other devices are cleansed by the injection of a washing solution into a region in the device or in a tissue pocket surrounding the device. In a first embodiment, the washing solution 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 washing solution 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 washing solution. Kits will include devices, syringes, access devices, and instructions for cleansing according to the methods of the present invention.

    摘要： A medical fluid administration system is provided for connection with an intravenous tubing system in fluid communication with a patient. In an exemplary embodiment the system includes a conduit, a housing connected to the conduit, and a piston having a slit received in the housing and displaceable in its entirety along the longitudinal axis of a region of the housing. A contact member is positioned within the housing for engaging the piston when the piston is displaced along the longitudinal axis of the housing and forcibly pressed against the contact member. The contact member and the piston are sized and configured such that the opposing walls of the slit are deflected laterally to open the slit when the piston is forcibly pressed against the contact member, so that when the piston is pressed against the contact member, fluid can flow through the slit in direct contact with the opposing walls and through the conduit.

    摘要： A feedback controlled drug delivery system includes the automated sampling and analysis of a patient sample and dosing the patient based on the analysis. Automated sampling may be performed by direct analysis of the patient sample, such as for the measurement of a blood sample coagulation state or a glucose level. The drug delivery system includes a sample set that has a bidirectional patient tube that allows for delivery of the patient sample to an analyzer, and at another time, the infusion of a therapeutic drug. A controller receives a measurement from the analyzer, and based on that measurement, adjusts the delivery of the therapeutic fluid. The sample set has a quick--clear Leur fitting that allows for more effectively clearing a first fluid from a Leur fitting when starting a second fluid. The system also has a reagent cassette holder that protects, using a foam gasket, a reagent on a sample slide. Further, the system provides an interlock apparatus that assures a sample tube is occluded by either or both a slide clamp and by a platen arm compressing the sample tube to a peristaltic pump.

    摘要： A flow adjusting tube clamp is used with a chamber in a solution administration device. The tube clamp is pivotally mounted to the cap at a second pivot element. The tube clamp includes first and second elongated tube passages that overly the cap inlet ports as the clamp is pivoted. The tube passages define varying cross-sectional open areas therethrough. The passages are arcuate so that they continuously overly the inlet ports as the clamp is pivoted. The inlet ports are configured to receive flexible tube portions that traverse through the tube passages in the clamp. Each tube passage includes at least one open area and at least one occluding portion to establish and terminate flow therethrough. The clamp is pivotable from a prime position to an intermittent flow position and from an intermittent flow position to a continuous flow position, to effect varying flow conditions.
