Pressurized drainage tube for chest

[0025] See figure 1 , figure 1 It is a structural schematic diagram of a pressurized drainage tube for upper lobectomy disclosed by the present invention. As shown in the figure, a pressurized drainage tube for chest cavity is proposed according to the purpose of the present invention. It includes a chest tube 1, an air bag 2 arranged on the chest tube 1, an air intake tube 3 for inflating the air bag 2 is arranged on one side of the chest tube 1, and at least one drainage hole 4 is opened on the front end of the air bag 2 on the chest tube 1 The shape of the airbag 2 after inflation matches the shape of the upper lung lobe in the chest cavity, and the airbag 2 can fill the chest cavity to balance the pressure of the chest cavity after inflation. By designing the inflated shape of the airbag to the shape of the upper lung lobe, it is suitable for hemostasis in patients with upper lobectomy to balance the pressure in the thoracic cavity.

[0036] Such as figure 2 As shown, the rest are the same as in Example 1, the difference is that the airbag is arranged on the lower side of the chest tube, and the shape of the airbag 2 after inflating matches the shape of the lower lobe or middle and lower lobe of the chest cavity, and the airbag 2 can be filled after inflating Thoracic cavity to equalize the pressure in the chest cavity. By designing the inflated shape of the airbag to the shape of the lower lobe or the middle and lower lobe, it is suitable for hemostasis in patients with lower or middle and lower lobectomy to balance the pressure in the thoracic cavity.

[0038] Such as image 3 As shown, the rest are the same as in Example 1, the difference is that the airbags are two located on both sides of the chest tube 1, the airbags on both sides are spliced ​​to form the entire lung, which matches the shape of the whole lung, and the airbag 2 can be filled after inflated Thoracic cavity to equalize the pressure in the chest cavity. The shape of the whole lung is formed by splicing the inflated airbags, which is suitable for hemostasis in patients with pneumonectomy to balance the pressure in the thoracic cavity.

[0039] In addition to being used for thoracopulmonary resection and filling, the present invention can also be used for other abdominal organs such as spleen removal, etc., as long as the upper and lower airbag shapes are designed to correspond to organ shapes, and the corresponding organ shapes can be formed by splicing after inflating , there is no specific limit.
