Claims (1)

[Claims for Utility Model Registration] (1) A dual valve body rigid container having three cylindrical openings that allows liquid to flow into the inside of one of the openings A from the outside. A check valve is provided inside the other opening B to prevent fluid from flowing in from the outside and allow fluid to flow out from the inside. a suction pump assembly in which an expression cylinder is incorporated into a double valve body rigid container, which is provided with an adapter in which the tip of the syringe cylinder is airtightly fitted in the other opening C; A body fluid suction and discharge device comprising an indwelling needle connected to the opening A directly or via an extension tube, and a connecting tube connected to the other opening B for transporting drainage fluid. (2) A tube that bypasses the dual valve body is disposed between the extension tube connecting the opening A and the indwelling needle and the tube for transporting waste fluid, and a clamp that can be freely opened and closed on the tube conduit. The body fluid suction and discharge device according to claim 1 of the registered utility model claim, characterized in that the body fluid suction and discharge device is equipped with a. (3) The indwelling needle is made of plastic, two lure-sized adapters are arranged at the needle base, and a clamp is attached to the extension tube to open and close the conduit. A body fluid suction and discharge device according to claim 1 of the patent registration claim. (4) inserting a rubber elastic tube into the two luer-sized adapters at the base of the indwelling needle so as to close the openings of the side adapters on the inside to prevent fluid from flowing outward; The body fluid suction and discharge device according to claim 1, which is a registered utility model, and further characterized in that injection cannot be performed unless the pressure is higher than a predetermined pressure. (5) The body fluid suction and discharge device according to claim 1, wherein the indwelling needle is a plastic indwelling needle, and one or more side holes are provided near the tip of the indwelling needle. (6) Body fluid suction and discharge according to claim 1, wherein the indwelling needle is a plastic indwelling needle, and marks are attached at one or more positions at a predetermined distance from the tip.
