Technical Field
The utility model relates to a medical instrument especially relates to a exempt from to sew up fixed drainage tube.
Background
After an abdominal or thoracic surgery, a drainage tube is usually left to drain residual blood, exudates and the like in the abdominal or thoracic cavity out of the body, so as to avoid postoperative hydrops and infection. Therefore, surgeons need to secure the drainage tube to the chest wall or the abdominal body surface safely, properly, and comfortably, to prevent the inner section of the drainage tube from falling out of the chest or abdominal cavity, and to prevent the outer section of the drainage tube from falling out of the chest or abdominal cavity.
The most common drainage tube at present is a hollow rubber tube or PVC tube, and the most common method is to suture a thread on the body surface skin near the orifice of the abdominal or thoracic drainage tube and then bind the thread to the external section of the drainage tube. Suturing a thread to the skin can result in scarring, and continued pulling after surgery can cause pain and require later removal of the thread. The silk thread is bound at the external section of the drainage tube, if the binding is not firm, the drainage tube can be separated from the body, and if the binding is too tight, the internal diameter of the drainage tube can be narrowed, the drainage is not smooth, and even the drainage is blocked.
In order to reduce the pain caused by the suture, some new suture-free drainage tubes are provided at present, an air bag is respectively arranged at the inner section and the outer section of the drainage tube body, and the two air bags are expanded by injecting air to play a role in fixing the drainage tube. However, in this method, an injector is required to inject air, and there is a risk of air bag rupture, air leakage and failure of air exhaust, the distance between the two air bags is fixed, while the thickness of the chest wall or the abdominal wall of different people is different, if the distance between the two air bags is significantly larger than the thickness of the chest wall or the abdominal wall, the sliding of the drainage tube may be caused, the outer section of the drainage tube is contaminated with bacteria, the inner section of the drainage tube is clean and sterile, and if the outer section of the drainage tube slides into the chest wall or the abdominal wall, the chest cavity or the abdominal wall, the infection may be caused. If the distance between the two balloons is significantly smaller than the thickness of the chest wall or the abdominal wall, the drainage tube cannot be indwelling, and the balloons press against the chest wall or the abdominal wall, resulting in necrosis of skin tissues.
