Blood reservoir and oxygenator in combination

Blood reservoir

Holder for blood reservoir

A medical tube clamp wherein first and second plate parts including, on opposing surfaces, compressive protrusions for closing a medical tube are provided with a pair of side walls on both sides projecting from one toward an other of the plate parts, and are also provided with a central guide protrusion projecting from the other toward the one of the plate parts. Both sides of a tip portion of the central guide protrusion make sloping guide surfaces projecting toward a center. When the plate parts are displaced relative to each other so as to become closer, lateral displacement of them is corrected by a slide of the pair of side walls and the sloping guide surfaces, and the central guide protrusion is inserted between the pair of side walls.

Blood reservoir with oxygenator

There is provided a winged indwelling needle for reducing the possibility of damaging a blood vessel or the like by a cannula, including a movable unithaving the cannula and a hub, a tubeconnected to the rear portion of the hub, a holder, and a fixing wing, in which the movable unitis provided on the holderso as to be capable of sliding in the axial direction, is capable of changing in position between a position in use and a stored position which is behind the position in use, and the movable unitis fixed to the position in use so as to be releasable. The holderincludes a protecting cylinderwhich stores only the front portion including a blade pointA of the cannulain the interior thereof when the movable unit is positioned at the stored position and is provided with the fixing wing, and a guide memberexposed upward for guiding the sliding movement of the movable unit

Indwelling needle with wings

An inserter includes a housing, a plunger holding an indwelling member, a lifter contained in the housing in the state where the lifter is axially movable relative to the plunger, a needle holder contained in the housing and having a projection that can be latched by the plunger and the lifter, an insertion needle held by the needle holder and inserted in a cannula, and a spring provided between the plunger and the lifter and applying a biasing force in the direction of biasing the plunger and the lifter away from each other. The projection of the needle holder is latched by the plunger before the indwelling member reaches the body surface of the user, and latched by the lifter after the indwelling member reaches the body surface of the user.

A protector for housing a drug administration needle comprised of a winged hub and a cannula bent substantially perpendicular to a longitudinal axis of the hub at a longitudinal central portion of the hub. The protector comprises a tubular cannula-protecting portion having a cannula entrance at one end and a bottom at the opposite end; and a hub-mounting portion for attachment of the winged hub, the hub-mounting portion being coaxially formed on the cannula entrance of the cannula-protecting portion.
