Technical Field

[0001] The utility model belongs to the technical field of medical devices, and more specifically, relates to a device for sucking accumulated fluid. Background Art

[0002] When a part of the body is infected or an autoimmune reaction occurs, the immune system will activate its defense mechanism, resulting in increased vascular permeability, causing fluid and cellular components to seep into the tissue spaces, forming effusions.

Timely extraction of the effusions can help restore normal physiological functions. However, traditional methods usually use manual syringes or simpler negative pressure suction devices. However, these devices have difficulty in ensuring the stability of suction. Due to the unstable suction, the effusion cannot be continuously and effectively extracted, and excessive or insufficient suction will have a direct negative impact on the treatment effect.
