Description

Cross flushing drainage tube

Technical Field

The invention relates to the technical field of medical instruments, in particular to a cross-shaped flushing drainage tube.

Background

With the progress of the times, the rapid development of science and technology, the medical level is continuously improved, the treatment capacity of serious diseases, particularly malignant tumors, is continuously enhanced, the surgical skills of a plurality of hospitals are continuously improved, the crowd is benefited, and the human beings are continuously advanced on the way of overcoming the diseases. However, with the development of some major operations, the operation wound surface is large, and the phenomena of exudation, bleeding, necrotic substances and effusion accumulation can occur at the wound surface, for example, the oozing blood and necrotic tissues are not cleared in time, so that the healing of the operation wound surface can be affected, even the operation wound surface is infected and the anastomotic stoma is open under severe conditions, severe patients can further cause severe infection of the abdominal cavity and hemorrhage of large blood vessels, and finally the death of patients is caused. The current solution which is commonly used clinically is to drain the oozing blood and necrotic tissues out of the body of a patient by using a negative pressure drainage technology, namely, a negative pressure drainage tube is arranged at the position of a wound surface, and the accumulated liquid is drained by using negative pressure. However, in general, the negative pressure drainage tube is easily sealed by necrotic tissues in the suction process, so that the negative pressure suction tube cannot work normally, and the postoperative rehabilitation is influenced. Moreover, when the anastomotic fistula occurs in the wound anastomotic stoma, the digestive tract contents and digestive juice leak to the periphery of the anastomotic stoma, and if the leakage liquid cannot be drained in time, the risk of infection and bleeding is increased sharply, and at this time, exogenous sterile normal saline is needed to flush the local part, dilute the leakage liquid and drain the leakage liquid.

The drainage tube that uses always clinically at present has single chamber and two-chamber drainage tube, and the single chamber includes the ordinary drainage tube that drainage effect is general and the better cross drainage tube of drainage effect, nevertheless all lacks the washing function, can not in time dilute the weeping liquid in time and the drainage goes out the patient external when complication such as anastomotic fistula has taken place, and ordinary two-chamber pipe has the washing function, but the drainage effect is not good, and the drainage hole is blockked up easily and is influenced the drainage effect.

Chinese patent documents: CN203749999U discloses a washable pressure-resistant drainage tube, which comprises a drainage section tube body, a hollow section tube body, a flushing tube and a flushing tube joint, wherein a reinforcing rib with a cross-shaped section is arranged in the drainage section tube body; this cross strengthening rib of patent document has strengthened the crushing resistance of drainage section body greatly, has guaranteed drainage speed when increasing drainage tube crushing resistance, when meetting great clot and blockking up the drainage section, can dredge the drainage section through the mode of injecting into the flush fluid from the flushing pipe, has avoided the emergence of jam to the realization lasts the drainage, has reduced the infection rate, has effectively reduced treatment cost. But it separates into the mode of three drainage chambeies and a washing chamber through arranging the strengthening rib, makes the washing chamber occupy one side pipe wall, very big restriction drainage efficiency.

In summary, a cross-shaped washing drainage tube which can realize drainage washing, can ensure efficient drainage efficiency, can effectively prevent the drainage tube from being blocked, and is simple in structure and convenient to use is urgently needed.
