    摘要: An irrigation solution re-circulating system comprises a reservoir of irrigation solution, a solution supply line for joining the reservoir in fluid communication with a surgery site for delivering a controlled volume, pressure, and temperature of the irrigation solution to the surgery site, and a return line for further joining the surgery site in fluid communication with the reservoir. A pump, which is preferably non-hemolyzing, is connected to the return line for returning a controlled volume of the irrigation solution from the surgery site to the reservoir. The system further comprises at least one filter connected to the return line for removing contaminants from the irrigation solution prior to return to the reservoir to permit re-circulation of the solution without impairing endoscopic visualization of the surgery site, while providing solution for expanding the surgery site to permit performance of the attendant surgical procedure.

    摘要: The present invention provides a package for and method of packaging a sterilizable calibratable medical device including a hydratable sensor component. The device is maintained in a sterile environment during storage and in a clean environment during the calibration procedure. The package includes a manifold connected to the sensor component by plumbing. The plumbing establishes fluid communication between the manifold and the sensor component and/or between the sensor component and the ambient environment of the plumbing. The manifold, plumbing and medical device are sealed in a wrap including a gas-permeable surface. The wrap and its contents, including the interior surfaces of the components, are sterilizable by exposing the wrap to a gaseous sterilization solution and appropriately adjusting the plumbing. The medical device is hydratable by directing the hydration solution to the sensor component by means of the plumbing. In order to store the package over an extended period of time, a gas-impermeable chamber is defined which includes the ambient environment of the plumbing. The gaseous environment of the medical device is thereby controllable. In this manner, the device is prepared for calibration and is storable in the sterile environment. By connecting a reservoir including calibration solution to the plumbing, the calibration solution is directed to the sensor component without removing the medical device from its clean environment. The temperature of the sensor component and the solution are controlled throughout the calibration process in order to ensure that the device is calibrated in accordance with its intended use. The present invention further discloses a solution for preparing the medical device for use. The solution is chemically compatible with the intended use of the device.

    摘要: A cap and Luer connector arrangement with an improved external seal is provided for a fluid transfer connector or fitting that has a nozzle with a surrounding annular collar located coaxially within a surrounding sealing lip. The cap includes a structure of resilient material which defines an end wall, an annular, inner sleeve extending from the end wall, and an annular, outer skirt extending from the end wall to define an annular receiving channel between the outer skirt and the inner sleeve. At least a portion of the inner sleeve has an inner surface for sealingly engaging the nozzle. A distal end of the outer skirt includes a seal region having a V-shaped cross-sectional crevice. The Luer connector sealing lip and seal region are distorted when the sealing lip is received into the crevice during initial screwed-on installation of the cap to the Luer connector, forming an external seal. The sealing lip and seal region are heat set during autoclave-sterilization of the cap and Luer connector arrangement, which prevents reinstallation of the cap once removed.
