Chest drainage water-sealed bottle

Abstract

The invention discloses a chest drainage water-sealed bottle and relates to the technical field of a medical instrument. The chest drainage water-sealed bottle comprises a bottle body, an exhaust pipe and a drainage passage for communicating an inner cavity of the bottle body with a human thorax; the drainage passage comprises a thin drainage pipe of which the outer diameter is smaller than 2.2mm, a thick drainage pipe of which the outer diameter is greater than 11mm and a water-sealed pipe of which the front end is connected with the thick drainage pipe and the rear end is inserted into the bottle body; the rear end of the thin drainage pipe is connected with a syringe needle connection part of a syringe; a joint part at the front end of the thick drainage pipe is inserted in a cylinder of the syringe; the bottle body is made of a transparent material and is provided with bottle body scales, a movable suspension loop and a movable supporting base. The chest drainage water-sealed bottle solves the problem that due to the relatively thick drainage pipe of the water-sealed bottle and a large contact area of the drainage pipe, which extends into the human thorax, of the water-sealed bottle and a human body, damage to an operation position is easy to cause and a patient easily feels uncomfortable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a water-sealed bottle for chest drainage. Background technique [0002] The water-sealed bottle is the basic device for closed pleural cavity drainage, and is suitable for closed pleural cavity drainage after various causes of pneumothorax, pleural effusion and surgery. Closed pleural cavity drainage is an important measure to treat pneumothorax, hemothorax and empyema, and is a basic treatment measure in thoracic surgery. Closed pleural cavity drainage is designed according to the physiological characteristics of the human pleural cavity and relies on the liquid in a water-sealed bottle. It isolates the pleural cavity from the outside world and forms a closed device to maintain the negative pressure of the pleural cavity. When high pressure is formed in the pleural cavity due to effusion or gas accumulation, the liquid or gas in the pleural cavity can be discharged into ...
