Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary products, in particular to a chest closed drainage pipeline locking device. Background Art

[0002] Closed chest drainage is mainly accomplished through drainage tubes and drainage bottles. During drainage, one end of the drainage tube is connected to the inside of the chest cavity, and the other end is connected to the drainage bottle, so that the effusion in the chest cavity is drained to the drainage bottle through the drainage tube. This is the method of closed chest drainage. Generally, when patients undergo closed chest drainage, they need to find the drainage position accurately. For patients with pneumothorax, it is necessary to drain from the second rib and the midclavicular line. For patients with effusion in the chest cavity, it is necessary to drain from the side of the chest wall where there is less soft tissue and it is easy for effusion to accumulate. When performing closed chest drainage on patients, the drainage tube and drainage bottle need to be fixed, and they need to be airtight to prevent infection.

[0003] In actual clinical practice, after the patient has completed closed chest drainage, a drainage tube will be left inside the chest cavity to facilitate the connection with the closed chest drainage bottle to drain the effusion. The closed chest drainage bottle includes a bottle body, a connecting tube and a connector. When the patient is draining the pleural effusion, he needs to first pour physiological saline into the bottle body until the liquid level is flush with the reference scale line, and then connect one end of the drainage tube left in the patient's chest cavity to one end of the connector, and the other end of the connector is connected to one end of the connecting tube, and the other end of the connecting tube is connected to the bottle body; the effusion in the patient's chest cavity is drained into the bottle body after passing through the drainage tube, the connector and the connecting tube. The current problem is that the drainage tube is implanted in the human body. For patients with a long drainage time, the drainage bottle needs to be replaced regularly, and the drainage tube needs to be separated from the connector. Multiple connection and separation operations will cause the connection between the drainage tube and the connector to be loose, and sometimes there is also a problem of loose connection between the drainage tube and the connector due to production problems. There is now a clinical desire to have an auxiliary locking device that can lock the drainage tube and the connecting piece together when the connection between the drainage tube and the connecting piece is unstable, and prevents them from getting caught on the patient's clothes, bedding, etc., so as to avoid the risk of separation of the drainage tube and the connecting piece during the drainage process, thereby causing pneumothorax.
