Description
Technical Field
The invention belongs to the field of medical drainage tubes, and particularly relates to a body cavity drainage tube.
Background
In the day of increasing operations, various complications of the operations always afflict patients and surgeons, wherein the common one is adhesion, namely pleural adhesion formed in a chest cavity, intestinal adhesion formed in an abdominal cavity and pelvic adhesion formed in a pelvic cavity. The traditional tubular or spiral multi-channel drainage tube is generally placed in an operation area, the lowest point of the body position around the operation area is located, blood seepage or inflammatory exudation can exist on the surface of an operation wound and around the surface of the operation wound in the process of postoperative recovery, tissues around the drainage tube can be adhered to each other by the exudates to form a package, the exudates in a body cavity can not be sufficiently drained, and the exudates can form wider adhesion on the part. Slight adhesion can cause intermittent pain and discomfort in the operation area of a postoperative patient and affect the daily life of the patient. Adhesion in a more severe case may cause the normal function of the organs in the operation area to be affected, such as intestinal obstruction and intestinal necrosis caused by intestinal adhesion, and infertility caused by pelvic adhesion, which all need to be treated again by operation. In addition, various traditional anti-adhesion liquid medicines are liquid, are not easy to be uniformly smeared in a complicated body cavity, and easily flow out of the body cavity along a drainage tube together with exudates in the body cavity, so that the traditional anti-adhesion liquid medicines have limited effects and cannot effectively prevent various adhesions.
The head and horn of the body cavity heat perfusion chemotherapy are gradually exposed in the process of tumor treatment, the body cavity heat perfusion chemotherapy is gradually accepted and popularized by the medical community, but the abdominal cavity drainage tube used in the body cavity heat perfusion is still the traditional tubular drainage tube or the spiral multi-channel drainage tube, the traditional drainage tube can not prevent adhesion and package, the periphery of the pipeline is easily packaged, and finally, in the process of heat perfusion, hot water can not ensure that the hot water is fully and effectively perfused to most positions of the body cavity, so that the body cavity heat perfusion process has the condition of partial tissue omission. There is therefore a need for a more scientific body cavity drainage tube.
