The invention discloses a closed drainage apparatus for chests, and relates to the field of medical apparatus and instruments, in particular to structures of drainage equipment. The closed drainage apparatus comprises a drainage tube which is connected with two balloons and an inflating tube. An air passage and two air-through holes are reserved inside the wall thickness of the drainage tube, the air passage is axially arranged, and one end of the air passage is a blind end, while the other end of the same is communicated with the inflating tube. Each of the air-through holes is radially reserved, one end of each of the air-through holes is respectively communicated with the air passage, while the other end of each of the air-through holes is respectively communicated with the corresponding balloons. During thoracocentesis, an anatomical piercing pin knife is inserted into a human body's chest, a piercing knife is withdrawn with a sheath left inside the chest, the closed drainage apparatus for the chest is inserted into the human body's chest from inside the sheath which is taken out when a chest wall is rightly clamped on the middle portion of the two balloons. According to the arrangement, the balloons are guaranteed to clamp in a drainage wound and are sealed and air-proof after being sufficiently inflated.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to the structure of drainage equipment. Background technique [0002] During thoracentesis, the puncture knife assembly is inserted into the chest cavity of the human body, the puncture knife is withdrawn, the sheath tube is left in the chest cavity, the drainage tube is inserted into the chest cavity from the sheath tube, and the sheath tube is withdrawn. Common drainage tube has the following defects: 1, it is difficult to seal between the drainage tube and the drainage wound. 2. The body of the drainage tube is softened, squeezed and flattened under the dual factors of body temperature and muscle tissue pressure, resulting in poor drainage or even no drainage. 3. It is impossible to inject medicine into the chest cavity to flush the pipeline. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a ...
