Description

Technical Field

[0001] The utility model belongs to the technical field of water seal bottles, and particularly relates to a water seal bottle that prevents backflow. Background Art

[0002] The water seal bottle is a common and important device in the medical field, usually used in operations such as closed chest drainage. Its main function is to prevent outside air from entering the chest cavity through the principle of water seal, while being able to observe and record the discharge of gas or liquid in the chest cavity. When treating patients with pneumothorax, the gas in the chest cavity can be discharged into the water seal bottle through the drainage tube, and the water in the water seal bottle can prevent the outside air from flowing back into the chest cavity, which helps to re-expand the lungs and restore normal function. However, when the water seal bottle has reflux during use, reflux will occur when it is not operated properly. Reflux will cause the gas or liquid in the chest cavity to be unable to be effectively discharged, hindering the re-expansion of the lungs and the recovery of the disease. At the same time, the refluxed liquid may carry outside Bacteria, pollutants, etc. enter the chest cavity, causing chest infection and aggravating the patient's condition. Therefore, when the water seal bottle needs to be replaced during use, in order to prevent the water seal bottle from reflux, it is generally clamped on the outside of the external drainage tube with a hemostatic forceps. However, in the clamping process, the tube body may be deformed, causing the clamped area to sag inward, causing the inner channel of the corresponding area to narrow, which may easily cause blockage of the tube body. At the same time, the clamping method using the hemostatic clamp may easily cause scratches between the hemostatic clamp and the outer wall of the tube body, causing wear of the tube body.
