Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a mediastinum washes sleeve pipe.
Background
Full drainage is one of the main modes for controlling infection in surgery, and the irrigation sleeve negative pressure drainage is an important treatment measure for drainage, and the irrigation sleeve negative pressure drainage is clinically used for abdominal surgery, such as intestinal fistula, pancreatic fistula, incision deep infection and the like. When the sleeve negative pressure drainage is used for abdominal drainage, the main functions are as follows: 1) Can avoid the complications such as the damage or the blockage of the abdominal cavity tissue entering the negative pressure tube caused by the single-cavity negative pressure drainage; 2) The drainage liquid can be diluted by continuously flushing with the external physiological saline, so that wound cavity hydrops and necrotic tissues can be timely discharged, the wound surface and the pus cavity can be efficiently drained, the local part, particularly the periphery of the fistula, can be kept relatively clean, and the growth of fresh granulation tissues and the formation of the fistula can be promoted; 3) Reduce toxin absorption into blood, improve systemic symptoms and shorten hospitalization time.
At present, most of flushing sleeves used in clinic are made by doctors or related products in the market, are mainly used for abdominal surgery drainage, and are not suitable for flushing and drainage of neck anastomosis fistula after esophageal cancer operation. The main reasons are: 1) The pyogenic cavity of the esophageal-neck anastomotic stoma is mostly limited to the mediastinum, the space is relatively narrow, the specifications of the existing sleeve product or the self-made sleeve are difficult to match, the sleeve product or the self-made sleeve is mostly placed at a position where the progress incision is relatively shallow when being placed, and the ideal flushing drainage can not be achieved for the pyogenic cavity at the deep part of the mediastinum; 2) The existing sleeve product or the outer tube of the self-made sleeve is soft in texture, the mediastinum space is relatively small, and in addition, more factors exist relative to the abdomen of a patient in actions of neck movement, swallowing, cough and the like, so that the drainage of the flushing sleeve is not smooth; 3) The outer tube of the existing sleeve has no internal support, and when surrounding tissues are adsorbed or the negative pressure is too large, the outer tube is easy to flatten and block.
In order to solve the problems, the method adopted at present is to insert 2 sterile sputum suction tubes or gastric tubes into mediastinum after a neck incision is opened, wash one tube, suck the other tube, add a 3 rd tube as a suction tube if necessary, adjust the positions of the irrigation tube and the suction tube, and continuously wash negative pressure drainage. However, the treatment method has the defects of more pipe placing, high pipe falling risk and high pipe blockage occurrence rate.
Therefore, a mediastinum flushing sleeve is needed to solve the problem of negative pressure suction for continuous flushing of a cervical anastomosis fistula mediastinum septal cannula after esophageal cancer operation.
