Abstract: A water toy device utilizing elongated body having first and second surfaces and first and second ends. A pair of wings extend from the elongated body and are bendable to determine the path of travel of the device in a body of water. An elongated fin projects from the first surface from the elongated body to stabilize the movement of the device.

Abstract: The plunger of a hypodermic syringe has the usual head and shank, but the shank is of articulate construction to permit change from a normal straight operating configuration to an angular configuration, at which angular configuration the shank engages the syringe barrel to control the position of the plunger head. In some embodiments the shank bends through an angle of 180.degree. to lie along the exterior of the barrel and thereby straddle the rim of the barrel to cooperate therewith to limit movement of the plunger head inwardly of the barrel. The straddling folded shank may engage the barrel rim at selected points of the shank to immobilize the plunger head at selected positions. In other embodiments the articulate shank bends through only a small angle to cooperate with the barrel rim to control the plunger head.

Abstract: An intake tube is inserted into a cavity in a patient's body to withdraw fluid therefrom, and means including an outlet tube cooperates with the intake tube to form a passage that is connected to a vacuum source to withdraw the body fluid. The outlet tube has an outlet port for releasable connection to the vacuum source, and a removable plug closes the outlet port when a vacuum is not needed. A thin-walled, flexible reservoir communicates with said passage to accumulate fluid that may flow from the body cavity in the absence of a vacuum. In some embodiments of the invention, the reservoir encloses the two confronting ends of the intake tube and the outlet tube, the arrangement being such that when a vacuum is applied to the outlet tube, fluid flows directly from the intake tube to and through the outlet tube; and in the absence of a vacuum, fluid flows from the intake tube directly to the reservoir.
