Technical Field

[0001] The utility model relates to the technical field of drainage, in particular to a cardiovascular drainage device. Background Art

[0002] Drainage is one of the commonly used surgical methods in cardiovascular medicine, such as drainage of pericardial effusion or blood. Existing drainage devices for cardiovascular medicine generally include a drainage component that provides a power source and pipeline installation and a drainage bottle for storing liquid. However, existing devices have certain disadvantages. For example, a cardiovascular drainage device recorded in announcement number CN218652616U includes: a support plate, a carrier box is fixedly installed on the support plate, a storage structure is movably connected to the inside of the carrier box, an upper cover body is clamped on the carrier box, and an air extraction structure is connected to the upper cover body;

[0003] Although the above device can free the hands of medical staff and prevent the cardiovascular drainage tube from falling randomly, the above device lacks fixation with the nursing cart. When the device is moved by the nursing cart, the device may fall, and it is not convenient to quickly replace the liquid storage component, resulting in the liquid extraction tube easily shaking during manual replacement.
