Technical Field
The utility model relates to the field of medical equipment, concretely relates to wash smooth and easy chest tube of even drainage.
Background
The drainage tube is used for drainage in clinical surgery to guide pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, prevent postoperative infection and accelerate wound healing. The traditional drainage tube is generally made of materials such as silicon rubber or polyurethane, when in use, one end of the catheter is inserted into the drainage position in vivo or on a wound surface, and the other end of the catheter can be connected with other external apparatuses such as a drainage connecting tube and the like in vitro, and drainage is carried out in vitro through the action of internal pressure, gravity or negative pressure suction isopiestic pressure. The common drainage catheter for thoracic cavity, ventricle, cerebrospinal fluid, lumbar vertebra, craniocerebral drainage catheter, abdominal cavity, thoracic cavity, ventricle, bile duct, etc.
In the prior art, a utility model with publication number CN211096442U discloses a medical thoracic drainage tube, which comprises an outer sleeve and an inner core drainage tube, wherein the inner core drainage tube is positioned inside the outer sleeve, the front end of the inner core drainage tube extends out of the front port of the outer sleeve, and the side wall of the extending part is provided with a drainage side hole; the side wall of the outer sleeve close to the front port is provided with a first air bag, the side wall of the outer sleeve is embedded with a first air bag pipe used for being connected with the first air bag, and the free end of the air bag pipe extends out of the pipe wall of the outer sleeve and is connected with a valve. The utility model discloses an inner core and drainage tube of overcoat mainly are to the operating problem that appears in the operation process, use the gasbag to oppress the artery of damage, prevent the intercostal artery effectively and bleed and prevent that the drainage tube from deviating from.
The utility model discloses a grant utility model patent of publication No. CN104548322B also discloses a drainage catheter is washed to thorax, and this drainage catheter rear end leaves inclined side hole area needle chest pipe, takes guide wire pipe respectively one, and the chest pipe is put into to the conventionality after, opens chest pipe rear end inclined side hole leather plug, takes guide wire pipe to insert to suitable position from chest pipe inclined side hole, and the pipe rear end is fixed with the local embedding of chest pipe inclined side hole, pulls out the guide wire, external heparin cap. The flushing fluid enters the thoracic cavity through the catheter and is drained out through the chest tube. The drainage tube that this scheme provided can wash and the drainage to the thorax simultaneously, can pull out the pipe when need not washing, continues thorax closed drainage. However, this solution requires a separate insertion catheter during the irrigation process, which makes the irrigation process more complicated.
However, in view of the technical solutions of the chest drainage catheters disclosed in the prior art, most of the conventional drainage catheters have only a drainage function, or have drainage and flushing functions. However, in the actual operation process, especially for patients with empyema, the infected area is large, and the infected part of the thoracic cavity needs to be washed, and the conventional thoracic catheter with washing is difficult to wash the washing liquid uniformly to the infected area, so that the medicines such as antibiotics cannot reach the infected area sufficiently and uniformly, the cure time of the patients is prolonged, and meanwhile, as the drainage catheter, the liquid in the drainage catheter is solidified, and the unsmooth drainage is easy to occur. To the technical problem that exists among the prior art, the utility model aims at providing a thoracic drainage catheter, this pipe has drainage and washing function, can wash evenly simultaneously.
