Negative-pressure double-sleeve drainage tube

Abstract

The invention relates to a negative-pressure double-sleeve drainage tube which comprises an outer sleeve and an inner dredging sleeve. The negative-pressure double-sleeve drainage tube is characterized in that a plurality of convex strips are evenly distributed on the inner side wall of an inner section of an outer sleeve body in the circumferential direction, holes are formed in the centers of the convex strips, the holes of the convex strips converge with and are communicated with a channel formed in the outer end side wall of the outer sleeve body, a circle of groove is formed in the inner wall of an outer section of the outer sleeve body in the circumferential direction, and an opening, corresponding to the channel, is formed in the groove and is communicated with the channel. After the technical scheme is adopted, it is ensured that the in-cavity position of the outer sleeve is not moved, various blockages such as blood clots, tissue fragments and mixed proteins are simply and effectively cleared, smooth drainage is easily restored, passive drainage is safely and efficiently changed into initiative drainage, a best drainage effect is achieved and is the priority among priorities of conservative treatment means, and accordingly possible second operation is avoided.

Description

technical field [0001] The invention belongs to the field of medical drainage tubes, in particular to a negative pressure double-set drainage tube. Background technique [0002] Drainage is an important technique in medicine, and effective drainage is the goal. At present, most hospitals at home and abroad use ordinary rubber or silicone drainage tubes for drainage after thoracic and abdominal surgery or various organ tissue operations. The lumen of this drainage tube is easily clotted due to its structure and material (material). blocks and tissue cell protein aggregates, affecting the outcome of the disease and the observation and judgment of postoperative conditions; in the case of fistula, etc., it is impossible to effectively upgrade passive drainage to active drainage. Therefore, it is necessary to improve the traditional drainage tube. Contents of the invention [0003] The technical problem to be solved by the present invention is: thoracic cavity lung, heart, me...
