The invention belongs to the technical field of medical instruments, and discloses a hydrops drainage device for the cardiovascular medicine department, which comprises a suction bottle and a bottle rack, the suction bottle is clamped on the bottle rack through a lantern ring, the suction bottle is connected with a suction pipe, a negative pressure pipe and a first flow guide pipe in a sealed mode, the suction pipe is sleeved with a guide pipe, the negative pressure pipe is connected with a negative pressure suction pump. the inner side of the suction bottle is connected with a collecting plate, the lower end of the first flow guide pipe is sleeved with a flow guide pipe adjuster and an arch-shaped buffer pipe, the arch-shaped buffer pipe is connected with a liquid flowmeter, a liquid outlet pipe of the liquid flowmeter is connected with a second flow guide pipe, the second flow guide pipe is connected with a liquid three-way valve, two liquid outlets of the liquid three-way valve are respectively in pipe connection with a first liquid outlet pipe and a second liquid outlet pipe, the first liquid outlet pipe is connected with a first hydrops bottle, and the second liquid outlet pipe is connected with a second hydrops bottle. The hydrops drainage device solves the problems that in the drainage process of an existing hydrops drainage device, a hydrops bottle cannot be replaced, and the hydrops amount detection precision is low, and is suitable for hydrops drainage in the cardiovascular medicine department.
