Pericardial effusion assisted drainage device

Abstract

The present invention relates to the technical field of medical auxiliary devices and particularly relates to a pericardial effusion auxiliary drainage device. The pericardial effusion auxiliary drainage device comprises a puncture needle and a liquid storage tank, an upper part of an outer side wall of the puncture needle is provided with a connecting handle, besides, a needle body of the puncture needle is provided with a liquid inlet inner chamber and a liquid outlet inner chamber, a top end port of the liquid inlet inner chamber communicates with a liquid inlet connection pipe and a top end port of the liquid outlet inner chamber port communicates with a liquid outlet connection pipe; the other end of the liquid inlet connection pipe communicates with a liquid inlet pipeline, the otherend of the liquid outlet connection pipe communicates with a Y-shaped pipeline, the other ends of the Y-shaped pipeline respectively communicate with a liquid guiding pipe and an air guiding pipe, and inner chambers of the Y-shaped pipeline and liquid guiding pipe are respectively provided with a one-way valve; and the other end of the liquid guiding pipe communicates with a connecting pipe of the liquid storage tank, and besides, the other end of the air guiding pipe communicates with a suction cylinder. The pericardial effusion auxiliary drainage device is simple in structure and simple inoperation, can input physiological saline into pericardia of patients through the device after effusion is extracted from the patients, and has strong practicability and extremely excellent market promotion value.

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...
