Description

Technical Field

[0001] The utility model belongs to the technical field of bronchial occlusion kits, and particularly relates to a bronchial occlusion kit. Background Art

[0002] The bronchus is a section of pipeline from the carina of the trachea to the hilum of the lung, one on the left and one on the right. The left bronchus is relatively slender, while the right bronchus is relatively short and thick. In thoracic surgery, bronchial occlusion kits are often used to occlude one side of the bronchus, so that the lung on the occluded side is not ventilated, which is convenient for doctors' subsequent surgical operations. In the prior art, there are several problems with bronchial occlusion kits. First, the visible catheter in the bronchial occlusion kit often does not have a threaded wire support, so it is prone to the situation that the front end is too hard and the middle section is too soft due to material problems, and the supportability is poor. Second, the lens inside the visible catheter is easily contaminated during use, and the flushing tube in the prior art is often arranged parallel to the lens, so the lens cannot be flushed well. Third, for patients with a high opening of the right upper lung (opening above the carina), the existing occluder is difficult to occlude, and it is very difficult to perform single-lung ventilation of the left lung. Therefore, we propose a bronchial occlusion kit to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bronchial occlusion kit, which can perform single-lung ventilation in patients with various tracheobronchial anatomical structures during use, is easy to insert, has little damage, the lens is not easily contaminated, and is easy to be flushed clean and aspirated if contaminated.

A through hole is opened at the right end of the connecting cover 15. The occluder 1 is located inside the through hole. The right end of the visible catheter 11 is detachably connected to the left end of the connecting tube 12;

[0026] On the left side inside the visible catheter 11, a lens 16 is fixedly installed. Inside the visible catheter 11, two flushing tubes 17 are symmetrically installed in the front and back. The water outlet ends of the two flushing tubes 17 are both inclined towards the lens 16. The water inlet ends of the two flushing tubes 17 are jointly installed with a U-shaped connecting tube. On the upper side of the U-shaped connecting tube, a water inlet tube 18 is provided. The upper end of the water inlet tube 18 extends out of the visible catheter 11. Inside the wall of the visible catheter 11, an installation groove is opened. Inside the installation groove, a threaded steel wire 19 is fixedly installed. On the left side of the circumference of the visible catheter 11, a small cuff 20 and a large cuff 21 are respectively installed. Both the small cuff 20 and the large cuff 21 are provided with inflation tubes 22. One end of each of the two inflation tubes 22 extends out of the visible catheter 11 and is fixedly connected to a connector 23.

[0027] When the visible catheter 11 needs to be installed, the right end of the visible catheter 11 can be inserted into the left end of the connecting tube 12. The sputum suction assembly can extend into the visible catheter 11 through the second assembly tube 14. The visible catheter 11 is supported by the threaded steel wire 19 inside, which increases the flexibility of the tip of the visible catheter 11 and the support of the entire tracheal catheter.
