Description

technical field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an auxiliary drainage device for pericardial effusion. Background technique

[0002] The pericardium is a thin film covering the outside of the heart. There is serous fluid between the pericardium and the heart wall, which can lubricate the myocardium and prevent the heart from rubbing against the chest cavity and causing injury. Can be divided into serous pericardium and fibrous pericardium. Pericardial effusion is a relatively common clinical manifestation and one of the important signs of pericardial disease. Pericardial effusion can be seen in exudative pericarditis and other non-inflammatory pericardial lesions. It can usually be confirmed by physical examination and X-ray examination. Chronic pericardial effusion is formed when pericardial effusion persists for more than several months. When the pericardial effusion suddenly increases sharply, the adap...
