The first embodiment is as follows: referring to fig. 1-4, an easily-flushed dual drainage cannula for abdominal cavity comprises an outer cannula 1 and an inner core tube 2; the inner core tube 2 is arranged inside the outer sleeve 1, and a drainage cavity 3 is formed between the outer sleeve 1 and the inner core tube 2; one end of the outer sleeve 1 is provided with a drainage hole 101, and one end of the inner core tube 2 is provided with an inner hole 201; the end of the inner core tube 2 with the inner hole 201 is also provided with a cleaner 4, the outer wall of the cleaner 4 is abutted against the inner wall of the outer sleeve 1, and the cleaner 4 can be driven to move and scrape in the outer sleeve 1 by pulling the inner core tube 2. The cleaner 4 is a conical block 401, a horizontal end face on the conical block 401 is fixedly connected with one end of the inner core tube 2, and the outer wall of the conical block 401 is abutted against the inner wall of the outer sleeve 1. The outer wall of the conical block 401 is further provided with a plurality of notches 4011. The outer wall of the cleaner 4 is attached to the inner wall of the outer sleeve 1, when the drainage tube is blocked, the inner core tube 2 is pulled to drive the cleaner 4 to move and scrape the inner wall of the outer sleeve 1, so that the blocked human tissue is dredged and washed without replacing the drainage tube, the operation is more convenient, and secondary damage to the wound surface of a patient is avoided. Adopt conical block 401 as purger 4, the cone head on the conical block 401 can play the effect of direction in penetrating purger 4 and inner core pipe 2 in outer tube 1 to reach and make things convenient for the drainage tube to install the effect. The notch 4011 can make the liquid in the drainage tube pass through the conical block 401 when the conical block 401 is pulled to clean the blockage in the drainage cavity 3, thereby facilitating the pulling of the cleaner 4.

Referring to fig. 2-3, a threaded male connector 102 is mounted at one end of the outer sleeve 1 away from the drainage hole 101, a nut female connector 202 is mounted at one end of the inner core tube 2 away from the inner hole 201, and the outer sleeve 1 and the inner core tube 2 are fixed by the threaded male connector 102 and the nut female connector 202 in a threaded manner. The outer sleeve 1 and the inner core tube 2 are detached, connected and fixed.

Referring to fig. 2, a water flushing head 103 is connected to one end of the outer sleeve 1 far away from the drainage hole 101. The water flushing head 103 can be connected with a labor-saving saline injection bag, and the physiological saline is injected into the drainage cavity 3 to be washed, and meanwhile, the accumulated liquid in the abdominal cavity can penetrate through the self-sealing valve 1011 to enter the drainage cavity 3 from the one-way passing characteristic of the self-sealing valve 1011, and the physiological saline cannot penetrate through the self-sealing valve 1011 to enter the abdominal cavity, so that the isolation effect is achieved, and the washing effect of the physiological saline on the blockage in the drainage cavity 3 is increased.

In the utility model, firstly, the inner core tube 2 driving the conical block 401 penetrates into the outer sleeve 1, the inner core tube 2 and the outer sleeve 1 are fixed by matching the threaded connection male head 102 and the nut connection female head 202, thus completing the fixation of the drainage double sleeve, then one end of the drainage tube with the drainage hole 101 is inserted into the sinus on the abdominal wall and enters the abdominal cavity, the other end of the inner core tube 2 is connected with a negative pressure device, the pressure in the inner core tube 2 is reduced, the effusion in the abdominal cavity passes through the self-sealing valve membrane 1011 under the action of the pressure and enters the drainage cavity 3, passes through the inner hole 201 and enters the inner core tube 2, and finally flows out from the other end of the inner core tube 2, thus realizing the drainage function. In-process at the drainage, the human tissue of mixing in the abdominal cavity hydrops can enter into drainage chamber 3 and pile up and form the jam, after carrying out a period of drainage, be connected normal saline injection bag and wash water hole, thereby laborsaving salt solution erodees drainage chamber 3, female 202 is connected to the nut of rotating again, contact outer tube 1 and inner tube 2's threaded connection, outside pulling inner tube 2, thereby drive toper piece 401 and remove outward mutually, will pile up the tissue deposit in drainage chamber 3 through the conical duct and take out outer tube 1, thereby reach the purpose that conveniently washes, and easy operation, need not the plug drainage tube and change, can not cause the secondary damage to the patient's surface of a wound.

The second embodiment participates in fig. 5 to 7, and the present embodiment is different from the first embodiment in the structure of the cleaning device 4, and the specific difference is that: the washer 4 includes an air bag 402, a connecting tube 403 and an inflation port 404; the connecting pipe 403 is arranged in the inner core pipe 2, and the inlet and the outlet of the connecting pipe 403 are respectively communicated with the inflating port 404 and the air bag 402; the air bag 402 is arranged at one end of the drainage cavity 3 with the drainage hole 101; the air charging port 404 extends out of the inner core tube 2 through the outer wall of the inner core tube 2. The outer wall of the air bag 402 is also provided with a diversion trench 4021. Firstly, the air cylinder and the connecting rod are placed in the inner core tube 2, when the accumulated objects in the drainage cavity 3 need to be cleaned, the air bag 402 is inflated through the inflation hole, so that the air bag 402 is expanded and enlarged, the outer wall of the air bag 402 is abutted against the inner wall of the outer sleeve 1, then the inner core tube 2 and the air bag 402 are pulled, and the human tissue accumulated in the drainage cavity 3 is taken out of the outer sleeve 1 by rubbing the air bag 402 against the inner wall of the outer sleeve 1. Gasbag 402 is under the not expanded state, and is small, and it is more convenient to get into drainage chamber 3, adopts the expanded mode of blowing simultaneously, can both make gasbag 402 outer wall and the inseparable laminating of outer tube 1 inner wall when pulling gasbag 402 clearance plug at every turn, can not appear wearing and tearing lead to laminating inseparable, and the condition that influences 4 cleaning effects of purgers appears.
