Abstract

The invention relates to a negative pressure double-set drainage tube, which includes an outer sleeve and a dredging inner sleeve. There are pores, and the pores of the raised strips are converging and communicating with a channel arranged in the side wall of the outer end of the outer casing. The inner wall of the outer section of the outer casing is provided with a circle of grooves along the circumferential direction, and the corresponding channel is set in the groove Opening, the opening is connected with the channel. After adopting the above technical scheme: ensure that the position in the body cavity of the overtube is not moved, and various blockages such as blood clots, tissue fragments and protein mixtures can be easily and effectively removed, and smooth drainage can be easily restored, which is safe , Efficiently upgrade passive drainage to active drainage to achieve the best drainage effect is the most important thing in conservative treatment, so that it is possible to avoid secondary surgery.

Description

technical field [0001] The invention belongs to the field of medical drainage tubes, in particular to a negative pressure double-sleeve drainage tube. Background technique [0002] Drainage is an important technology in medicine, and effective drainage is the purpose. At present, most hospitals at home and abroad use ordinary rubber or silicone drainage tubes for drainage after thoracic, abdominal surgery or various organ tissue surgery. Blockage by lumps and tissue cell protein aggregates affects the prognosis of the disease and the observation and judgment of postoperative conditions; in the case of fistulas, it is impossible to effectively upgrade passive drainage to active drainage. Therefore, it is necessary to improve the traditional drainage tube. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: thoracic cavity, lung, heart, mediastinum and other parts, abdominal gastrointestinal, liver and gallbladder, postoperativ...
