The utility model relates to the technical field of medical devices, in particular to a cross-shaped irrigation and drainage tube.

Background technique

With the progress of the times, the rapid development of science and technology, the continuous improvement of medical level, the ability to treat some major diseases, especially malignant tumors, has been continuously enhanced, and the surgical skills of many hospitals have also been continuously improved, which has benefited the population and enabled mankind to overcome diseases on the road. continuous progress. However, with the development of some major operations, the surgical wounds are larger, and there may be exudation, blood oozing, necrosis, and accumulation of exudates on the wound surface. If these exuding blood exudates and necrotic tissues are not removed in time, it will affect the operation. The healing of the wound surface may even lead to infection of the surgical wound surface and the opening of the anastomosis in severe cases. In severe cases, it may cause severe infection in the abdominal cavity, large blood vessel bleeding, and ultimately lead to the death of the patient. At present, the most commonly used solution in clinical practice is to use negative pressure drainage technology to drain these oozing blood exudate and necrotic tissue out of the patient's body, that is, place a negative pressure drainage tube at the wound surface and use negative pressure to drain the effusion. However, under normal circumstances, the negative pressure drainage tube is easily sealed by necrotic tissue during the suction process, which makes the negative pressure suction tube unable to work normally and affects postoperative recovery. What's more, when an anastomotic leakage occurs at the wound anastomosis, the contents of the digestive tract and digestive juices leak around the anastomosis. If the leakage cannot be drained out in time, the risk of infection and bleeding will increase sharply. Local flushing with exogenous sterile saline is required to dilute and drain these exudates.

At present, the commonly used drainage tubes in clinical practice include single-lumen and double-lumen drainage tubes. Single-lumen drainage tubes include ordinary drainage tubes with average drainage effect and cross drainage tubes with better drainage effect, but they all lack the flushing function. When there are complications, the leakage fluid cannot be diluted and drained out of the patient in time. The ordinary double-lumen tube has a flushing function, but the drainage effect is not good, and the drainage hole is easily blocked, which affects the drainage effect.

Chinese patent document: CN203749999U discloses a flushable anti-pressure drainage tube, including a drainage section tube body, a hollow section tube body, a flushing tube and a flushing tube joint, and the drainage section tube body is provided with a cross-shaped reinforcement The tube body of the drainage section is divided into three drainage cavities and a flushing cavity by cross-shaped reinforcing ribs. The drainage notch is axially provided on the wall of the drainage cavity, and the flushing cavity wall is provided with a flushing hole. The flushing tube and the flushing cavity The cross-shaped reinforcing rib in this patent document greatly enhances the compression resistance of the drainage tube body, which increases the compression resistance of the drainage tube and also ensures the drainage speed. When a large blood clot blocks the drainage section, it can pass The drainage section is dredged by injecting the flushing liquid from the flushing tube, avoiding the occurrence of blockage, thereby realizing continuous drainage, reducing the infection rate, and effectively reducing the treatment cost. However, by arranging reinforcing ribs to separate into three drainage cavities and one flushing cavity, the flushing cavity occupies one side of the tube wall, which greatly limits the drainage efficiency.

To sum up, there is an urgent need for a cross-shaped irrigation and drainage tube that can not only achieve drainage and flushing, but also ensure high drainage efficiency, can effectively prevent the drainage tube from clogging, and has a simple structure and convenient use.
