Description

Technical Field

[0001] The present invention relates to the field of abdominal drainage, and particularly to an abdominal tube drainage device for preventing leakage. Background Art

[0002] Generally, after abdominal surgery, an abdominal drainage tube needs to be placed to drain exudate, blood, cavity fluid, etc. in the abdominal cavity to the outside of the body, so as to reduce the body's absorption of exudate toxins, prevent abdominal abscess, and at the same time observe whether postoperative complications occur. If the patient has a large amount of ascites, exudate often occurs around the abdominal drainage tube, contaminating the incision dressing. Therefore, a drainage device is often needed;

[0003] Patent: CN213099801U relates to an anti-leakage abdominal drainage device, including a liquid storage tank. One side of the top of the liquid storage tank is fixedly provided with a vacuum generator, and the vacuum generator is connected to the liquid storage tank through a pipeline in a penetrating manner. A hose is fixedly penetrated and provided at the top of the liquid storage tank. By setting a puncture head, it is convenient to insert the threaded drainage tube and the puncture tube into the patient's abdominal cavity for drainage. By setting the puncture tube, the surface of the puncture tube is smooth and convenient to penetrate into the patient's abdominal cavity, which can reduce pain. After the puncture tube is inserted into the patient's abdominal cavity, the threaded drainage tube is rotated through a rotating wheel so that one end of the threaded drainage tube extends out of the inner cavity of the puncture tube. The exudate in the abdominal cavity can flow into the threaded drainage tube from the drainage hole and then flow into the inner cavity of the liquid storage tank through the hose, which is convenient to use. By setting the vacuum generator and the pressure gauge, the vacuum generator can evacuate the inner cavity of the liquid storage tank, and the pressure gauge can detect the pressure in the inner cavity of the liquid storage tank, which is convenient for drainage operation;

[0004] In the above technology, only a single liquid storage tank can be used to collect abdominal fluid, which is not convenient for timely cleaning of abdominal fluid. Moreover, in the above technology, the sealing cover needs to be adhered to the human body through double-sided adhesive, which is easy to fall off after long-term adhesion and has a poor sealing effect, so improvement is needed. For this reason, we propose an abdominal tube drainage device for preventing leakage. Summary of the Invention

On the left side of the upper surface of the box body 1, two liquid inlets 2 are integrally formed. At the top of the two liquid inlets 2, a transfer box 1 is fixedly connected in common. On the left side of the transfer box 1, a flow control valve 4 is fixedly connected. At the left end of the flow control valve 4, a drainage tube 5 is fixedly connected. Inside the transfer box 1, a connecting cylinder 6 is provided. The inside of the connecting cylinder 6 is fixedly connected to the input end of the flow control valve 4. On the outer side wall of the connecting cylinder 6, two sealing cylinders 1 are rotatably connected through a rotating shaft;

[0032] A connecting rod 15 is fixedly connected in common between the two sealing cylinders 1;

[0033] On the lower surface of the sealing cylinder 1 in front of the connecting cylinder 6 and on the left side of the sealing cylinder 2 10 behind the connecting cylinder 6, through-type docking holes 1 are opened;

[0034] The drainage tube 5 is used for draining abdominal fluid. The introduced abdominal fluid will enter the inside of the connecting cylinder 6 through the flow control valve 4. By rotating the sealing cylinder 1, a set of docking holes 1 can be adjusted to be docked and communicated with the liquid inlet 2. In this way, the abdominal fluid can be controlled to enter separately from one of the two liquid inlets 2, and then the abdominal fluid can be controlled to flow into the front or the rear inside the box body 1;

[0035] On the right side of the upper surface of the box body 1, two vacuum ports 8 are integrally formed. At the top of the two vacuum ports 8, a transfer box 2 is fixedly connected.
