摘要： A disposable surgical drape having a folding funnel, folding frame means, and splash shield functions as a fluid collector for use during surgery. A portion of the splash shield is placed under the patient while the remainder extends over the operating table end to direct fluid flow to a folding funnel which is shaped and positioned as desired with folding frame means. Fluid draining into the funnel is collected for measurement. Folding frame means impart a substantially frusto-conical or frusto-pyramidal shape to the funnel in use and employ one or more hinged struts to help maintain the funnel mouth substantially open and horizontal.

摘要： A magnet keeper-shield assembly adapted to hold and store a permanent magnet used to generate a high gradient magnetic field that, in one embodiment, may penetrate into deep targeted tumor sites in order to attract magnetically responsive micro-carriers. The magnet keeper-shield assembly includes a magnetically permeable keeper-shield with a bore dimensioned to hold the magnet. A lever mechanism is used to push the magnet partially out of the keeper-shield. The actuator is assisted by several springs extending through the base of the keeper-shield.

摘要： A monitor to provide substantially real-time estimates of fluid absorption rate and tissue loss rate in a patient during a surgical procedure. The monitor estimates fluid source flow rates and waste fluid flow rates based on weight changes per unit time or direct reading fluid flow rate meters. Tissue loss flow rates are estimated based on tissue concentration measurable in waste irrigation fluid using an optical comparator, and are used to correct waste fluid flow rates. Correct waste fluid flow rates are used in turn to obtain estimated fluid absorption rates.

摘要： An improved liquid-filming apparatus of the type which utilizes centrifugal action to distribute blood on a specimen-display surface, i.e. on a conventional laboratory slide, and which utilizes a waste-collecting means about the perimeter of the slide display surface. The invention is based on the discovery that the display surface is advantageously related to the surrounding structure in such a way that blood does not disintegrate into minute droplets upon leaving the slide surface and before it can be immobilized in the collecting means. By providing a transitional blood-receiving surface immediately adjacent the supply surface, applicant has avoided the problem of such disintegration.

摘要： A cryosurgical probe has a refrigerant supply conduit for conducting refrigerant to the hollow thermally-conductive probe tip. A refrigerant exhaust conduit extends through the probe into the tip and the end of the exhaust conduit in the tip is positioned a selected distance proximally of the end of the supply conduit. Thus, when refrigerant flows through the supply conduit to the tip, it tends to follow a flow path taking it more or less directly to the exhaust conduit. This creates a dead gas space inside the tip proximally of the end of the exhaust conduit, thereby minimizing direct cooling of portions of the probe adjacent to and proximally of the dead gas space and confining the freeze zone distal to that space. By adjusting the height of the exhaust conduit end proximally of the supply conduit end, the size of the freeze zone at the tip can be controlled. Further, if the probe has a defrost mode, defrost is enhanced because only the working end of the tip need be warmed.
摘要翻译：冷冻手术探头具有用于将致冷剂传导到中空导热探针针头的制冷剂供应导管。制冷剂排出管道通过探针延伸到尖端中，并且尖端中的排气管道的端部被定位在供应管道的端部的近侧的选定距离处。因此，当制冷剂通过供应管道流到尖端时，倾向于遵循直接将它或多或少地排到排气管道的流路。这在排气管道的端部附近的尖端内部产生死气体空间，从而最小化与死气体空间相邻并近端的探针的部分的直接冷却，并将冷冻区限制在该空间的远端。通过调节供气管端部近侧的排气管道端的高度，可以控制尖端处的冻结区的大小。此外，如果探头具有除霜模式，则除霜需要加热，因此除霜是增强的。

摘要： A disposable wound treatment electrode is disclosed that is usable in combination with a releasable connector for enabling effective delivery of an electrical signal to a patient. The electrode and connector are configured so that the connector provides a readily accessible tool to facilitate disposal of the electrode after use, and a method of utilization for effecting this end is also disclosed. The electrode includes an electrically non-conductive cover sheet, an electrically conductive and preferably non-metallic disperser formed at least in part by carbon and having a portion, preferably integral with the remainder of the disperser, that extends through an aperture in the interior portion of the cover sheet, and a non-adhering wound contact sheet. In addition, protectors are provided for an integral portion of the disperser extending through the cover sheet, a retainer is provided to receive an electrically conductive skin moisturizer, and/or the peripheries of the cover sheet and the wound contact sheet are sealed together to form a closed envelope.
