[0024] Example:

[0025] A drainage device, in this embodiment, includes a syringe 1 and a suction tube 2, the top end of the suction tube 2 is threadedly connected to the syringe 1, and the bottom end of the suction tube 2 is provided with a drainage head 3; a discharge pipe 4 is provided on the suction tube 2, one end of the discharge pipe 4 is connected to the suction tube 2, and the other end of the suction tube 2 is provided with a connector 5 that matches the waste liquid container; a partition 6 is provided on a corner 7 where the discharge pipe 4 near the drainage head 3 meets the inner wall of the suction tube 2, and sealing pads 11 are provided on both end surfaces of the partition 6, and a sealing pad 11 is provided on the outer side surface of the partition 6 There is a sealing ring 12; a fixed shaft 8 is provided on the corner 7, and a rotating sleeve 9 is provided on the outer sleeve of the fixed shaft, and the outer part of the rotating sleeve 9 is integrally formed with the partition 6; a torsion spring 10 is provided between the rotating sleeve and the fixed shaft 8, and the torsion spring 10 is sleeved on the outer part of the fixed shaft 8; one end of the torsion spring 10 is fixedly connected to the fixed shaft 8, and the other end of the torsion spring 10 is fixedly connected to the rotating sleeve; the drainage pipe 4 is inclined with the suction pipe 2 along the direction close to the drainage head 3, and the inclination angle is greater than 15° and less than 75°. A first sliding groove 13 is provided on one side of the inner wall of the suction pipe 2 so that the axis of the partition 6 is parallel to the axis of the drainage pipe 4, and a second sliding groove 14 is provided on the other side of the inner wall of the suction pipe 2 so that the axis of the partition 6 is parallel to the axis of the suction pipe 2; the first sliding groove 13 and the second sliding groove 14 are respectively matched with the sealing ring 12.

[0026] Specific usage:

[0027] First, place the drainage head 3 to the drainage part of the patient, and then connect the connecting head 5 to the waste liquid bag. At this time, the partition 6 cooperates with the first sliding groove 13, and the torsion spring 10 is in the initial state. Then the medical staff starts the operation. The medical staff first starts the suction operation through the syringe 1. During the suction, due to the negative pressure of the syringe 1, the rotating sleeve 9 rotates, so that the partition 6 is disengaged from the first sliding groove 13, and the partition 6 is cooperated with the second sliding groove 14 (at this time the torsion spring 10 is in a compressed state). At this time, the channel of the suction tube 2 is opened, and the pipeline of the drain tube 4 is closed. Then the medical staff continues to perform the suction operation, thereby sucking the patient's accumulated fluid into the syringe 1.

[0028] When the syringe 1 is filled with accumulated fluid, the medical staff stops withdrawing the piston. At this time, the negative pressure provided by the syringe 1 disappears, causing the torsion spring 10 to rotate the partition 6 under the action of the restoring force, thereby allowing the partition 6 to disengage from the second sliding groove 14 and re-engage with the first sliding groove 13. At this time, the pipeline of the suction tube 2 is closed and the pipeline of the drainage tube 4 is opened. Then the medical staff squeezes the piston to slide back, so that the accumulated fluid is discharged from the drainage tube 4 into the waste liquid bag.

[0029] By continuously performing the above process, continuous suction and discharge of the accumulated fluid can be achieved. There is no need to disconnect the filled syringe 1 from the drainage tube, drain the accumulated fluid in the syringe 1, and then reconnect the drainage tube for suction. This operation is very convenient and avoids spilling of the accumulated fluid to pollute the environment.

[0030] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
