[0015] In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the utility model are described in detail with reference to the accompanying drawings for the preferred embodiments of the utility model and their features and functions.

[0016] As attached Figure 1-3As shown, the utility model provides a chest drainage tube for postoperative cardiac and vascular surgery, comprising a tube body 1, on which two electronic closing devices 2 are arranged, the electronic closing device 2 comprising an annular shell 21, a slide groove 22 is arranged on the side wall of the inner ring of the annular shell 21, a slider 23 slidably connected to the slide groove 22 is arranged in the slide groove 22, an electric telescopic rod 24 is arranged between the slide groove 22 and the slider 23, one end of the electric telescopic rod 24 is connected to an end of the slide groove 22 away from the inner ring of the annular shell 21, and the other end is connected to the slider 23, the end of the slider 23 away from the electric telescopic rod 24 is an arc shape with the same radius as the inner ring of the annular shell 21, a power supply and a signal receiver electrically connected to the electric telescopic rod 24 are also arranged in the annular shell 21, and the signal receiver is wirelessly connected to the electronic control board, the annular shell 21 is sleeved on the tube body 1, and the tube body 1 is pressed by the movement of the slider 23 to control the opening and closing of the tube body 1.

[0017] In actual use, before inserting the drainage tube, the operator can first extend the electric telescopic rod 24 through the electronic control panel, and let the slider 23 press the tube body 1 to close the tube body 1. After completing the intubation, control the electric telescopic rod 24 to retract, and move the two electronic closing devices 2 to 10-15 cm away from the intubation site, and then set the two electronic closing devices 2 to perform a squeezing operation every 30 minutes. During the squeezing operation, the electronic device away from the intubation site continues to close the tube body 1, and the other electronic closing device 2 continuously and quickly presses the tube body 1, so that the airflow repeatedly impacts the drainage tube opening to prevent blood clots from forming and blocking the tube opening. Then the two electronic closing devices 2 stop pressing the tube body 1 at the same time, and the pleural effusion can be discharged from the drainage tube under the influence of gravity. When replacing the drainage bottle, the operator can also close the tube body 1 through the two electronic closing devices 2 to avoid causing open pneumothorax.

[0018] In this embodiment, an annular buckle coaxial with the annular shell 21 is provided on the annular shell 21, and the annular buckle is engaged with the tube body 1. The operator can further fix the electronic closing device 2 through the annular buckle to prevent the electronic closing device 2 from moving.

[0019] In this embodiment, the tube body 1 is located in the chest cavity and is provided with a snake bone device 3 and a cylindrical guide rope cavity 32 adapted to the snake bone device 3. There are multiple guide rope cavities 32, and one end of the guide rope cavity 32 away from the snake bone device 3 is provided with an opening connected to the outside world. The traction rope 31 of the snake bone device 3 is located in the guide rope cavity 32, one end of the traction rope 31 is connected to the snake bone device 3, and the other end is located outside the guide rope cavity 32. A fixing ring engaged with the traction rope 31 is provided at the opening. After the operator inserts the tube body 1 into the patient's body, the snake bone device 3 is located in the patient's body and the opening is located outside the patient's body. The operator can change the bending direction of the snake bone device 3 by operating the traction rope 31, thereby changing the position of the end of the tube body 1 to avoid discomfort to the patient caused by repeated intubation.

[0020] The above description is only the preferred embodiment of the utility model, not all embodiments. Anyone should be aware that structural changes made under the inspiration of the utility model, and all technical solutions that are the same or similar to the utility model, belong to the protection scope of the utility model.
