Example Embodiment

[0024] Example 1

[0025] See figure 1 , figure 1 It is a schematic structural diagram of a pressurized drainage tube used for upper lobectomy surgery disclosed by the present invention. As shown in the figure, a pressurized drainage tube for thoracic cavity is proposed according to the purpose of the present invention. The pressurized drainage tube It includes a chest tube 1, an airbag 2 arranged on the chest tube 1, an air inlet tube 3 for inflating the airbag 2 is provided on one side of the chest tube 1, and at least one drainage hole 4 is provided on the chest tube 1 at the front end of the airbag 2 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 in the chest cavity after inflation. The shape of the airbag after inflation is designed into the shape of the upper lung lobe, which is suitable for patients with upper lobectomy for hemostasis and balances the...

Example Embodiment

[0035] Example 2

[0036] Such as figure 2 As shown, the rest is the same as Example 1, except that the airbag is arranged on the lower side of the chest tube. The shape of the airbag 2 after inflation matches the shape of the lower or middle and lower lung lobes in the chest cavity. The airbag 2 can be filled after being inflated. The chest cavity to balance the pressure in the chest cavity. By designing the shape of the inflated airbag into the shape of the lower lobe or the middle and lower lobes, it is suitable for hemostasis in patients with the lower or middle and lower lobes resected to balance the pressure in the chest cavity.

Example Embodiment

[0037] Example 3

[0038] Such as image 3 As shown, the rest is the same as in Example 1, except that the airbags are 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. The airbag 2 can be filled after being inflated. The chest cavity to balance the pressure in the chest cavity. The airbag is inflated and spliced ​​to form the shape of the whole lung, which is suitable for patients undergoing pneumonectomy for hemostasis and balances the pressure in the chest 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. As long as the shape of the upper and lower airbags is designed into the corresponding organ shape, the corresponding organ shape can be formed by splicing after inflation. , No specific restrictions.

[0040] The invention discloses a pressurized drain...

Abstract

The invention discloses a pressurized drainage tube for a chest. Air bags are arranged on a chest tube; the air bags are aerated to be expanded continuously, a shape of the aerated air bags is matched with the shape of lung lobes, or matched with the shape of other spleens; when an organ is removed, the chest tube is inserted into the chest and then the air bags on the chest tube are aerated, so that the air bags effectively fill the chest to ensure equalization of the pressure in a human body, reduce even avoid the phenomenon of exudation of a chest wall; the pressure in the air bags can be increased or reduced according to the situation of exudation in the chest after operation, the pressure in the air bags is gradually reduced along with post operation time, then residual lung is expanded correspondingly, and finally the aim of removing the pressurized drainage tube is achieved; and meanwhile, the air bags companion the chest tube, once the air bags leak or air and blood exist in a cavity, the air and the blood can be drained by drainage holes in the chest tube through the chest tube timely, and the problems of discharge of pneumatosis and dropsy in the chest are also effectively solved.

Description

technical field [0001] The invention relates to the technical field of postoperative thoracic cavity drainage, in particular to a pressurized drainage tube for the thoracic cavity. Background technique [0002] After thoracotomy, due to lobectomy or pneumonectomy, there is a huge cavity left in the thoracic cavity, and the negative pressure in the thoracic cavity generated by postoperative breathing may increase the amount of blood and fluid in the thoracic cavity. Second or even multiple thoracotomy to stop bleeding will increase the patient's medical expenses and prolong the hospital stay. [0003] The traditional way to deal with extensive bleeding in the chest cavity is gauze filling: by using medical uterine gauze, the residual cavity in the chest cavity is filled in a certain order, and the gauze is gradually drawn out 2-3 days after the operation. The problem is that the opening of the thorax after surgery is likely to cause intrathoracic infection, and at the same t...
