Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to abdominal cavity drainage tube that sustainable negative pressure washed.
Background
The abdominal cavity drainage tube is widely used in general surgery department operations, and mainly aims to drain abdominal cavity contents through the drainage tube, discharge residual or continuously generated seepage, hematocele, fistula contents and necrotic tissues in an abdominal cavity out of the body through the drainage matters, judge whether complications such as hemorrhage, intestinal fistula, pancreatic fistula, biliary fistula and the like occur in the abdominal cavity, relieve abdominal cavity infection and prevent postoperative abdominal cavity abscess from occurring.
At present, flushable drainage tubes such as a dripping double-cannula (Richardson tube) are applied, the purpose of flushing and draining abdominal cavities is achieved through water inlet of an outer tube and suction of an inner tube, and the double-cannula flushable drainage tube has relevant and therapeutic significance for treating the disease conditions of hematocele, effusion, abdominal abscess and digestive tract fistula. However, this type of drainage tube has the following problems:
the negative pressure suction force is difficult to control: in clinical use, the abdominal drainage tube is retained in the abdominal cavity and is often adjacent to tissues and organs such as intestinal wall, blood vessel, omentum majus, gallbladder and pancreas, the suction force of the drainage tube is too small to suck out the effusion, and the suction force of the drainage tube is too large to easily lose the tissues and organs in the abdominal cavity, thereby causing iatrogenic complications such as hemorrhage, intestinal fistula, biliary fistula and the like. The peritoneal irrigation drainage tube is often connected with a central negative pressure machine or a movable negative pressure machine, the suction force can not be accurately controlled, and particularly the movable negative pressure machine is only sucked by one suction force, so that the abdominal cavity is easily damaged by the aid of the suction force. In addition, even if the negative pressure suction device can maintain a certain negative pressure suction force, because the seepage speed of the drainage fluid in the abdominal cavity is not constant, when the seepage fluid is less, the drainage tube is easy to adsorb adjacent tissues and organs to cause side damage.
(II) water leakage: the drainage tube is easy to adsorb necrotic tissues to cause pipeline blockage in the process of flushing and drainage, and the suction force in the drainage tube is reduced; the irregularity of the tube wall prevents the skin at the opening of the drainage tube from being completely attached to the drainage tube; these all cause the effusion to flow out of the operation mouth, pollute the operation mouth and increase the psychological burden of the patient and the workload of medical care.
