    摘要： A pump module includes a peristaltic pump having a pump rotor, a drive mechanism to rotate the rotor, and a tubing clamp adjacent to and separate from the peristaltic pump. A cover is movable between a closed position on the pump module, enclosing both the pump rotor and the tubing clamp, and an opened position spaced from the pump module, exposing both the pump rotor and the tubing clamp. The cover carries a tubing organizer, which holds tubing. The tubing organizer serves, as the cover moves toward the closed position, to orient the tubing in a desired way with the pump rotor and tubing clamp. The tubing organizer also serves, as the cover moves toward the opened position, to orient the tubing away from the pump module.

    摘要： Blood separation systems and methods utilize a membrane separation device comprising a gap between a microporous membrane and a surface facing the microporous membrane, one of the microporous membrane and the surface being rotatable relative to the other to cause separation of whole blood in the gap into plasma and concentrated red blood cells. The systems and methods include an inlet pump element coupled to the membrane separation device to convey whole blood having a known beginning hematocrit value into the gap for separation. The systems and methods also include a drive element coupled to the membrane separation device to cause rotation of the rotatable one of the microporous membrane and the facing surface. The systems and methods command the inlet pump element and the drive element as a function of the known beginning hematocrit value. This command technique obtains concentrated red blood cells having a high end hematocrit value that remains substantially constant despite variances in the known beginning hematocrit value, and, in particular, when the known beginning hematocrit value is low.

    摘要： A safety trocar is provided which includes a spring-loaded shield that shields the cutting tip of the obturator after the obturator penetrates tissue. The distal end of the shield is hemispheric in profile and contains a slot which conforms to the geometry of the cutting tip. The rounded distal end enables the shield to spring forward to shield the cutting tip as soon as the tip perforates the tissue. A valve is located at the proximal end of the trocar tube to seal the end of the tube. The valve is oriented at an acute angle with respect to the longitudinal axis of the trocar tube. The valve is controllable by an external lever which will hold the valve open or permit it to spring shut. An incremental advancement mechanism cooperates with the obturator to permit only incremental advance of the obturator. Instead of using a discrete shield component the shielding function may be provided by spring-loading the trocar tube itself to spring forward and shield the obturator tip after the tip penetrates tissue.

    摘要： An improved surgical instrument is described. The instrument comprises a housing. The housing has a handle for activating a force, and a link for translating the force. The instrument also comprises a probe. The probe has jaws or an anvil for holding a single wound closure element, a movable crimp bar for crimping the single closure element in the jaw or anvil, the proximal end of the crimp bar being connected to the distal end of the link, a spring for advancing a plurality of wound closure elements, and an injector for loading a single wound closure element, from the plurality, into the jaws or onto the anvil. The improvement comprises the link indirectly connected to the spring and the injector to integrally effect the crimp bar, spring and injector.The surgical instrument can be a ligating instrument.
