Abstract

The invention relates to an atrial shunt system, and belongs to the technical field of medical instruments. The atrial shunt system comprises an atrial shunt conveying device and an atrial shunt, the atrial shunt conveying device comprises a hanging head switch, a sliding valve, a handle, an outer sheath tube, a pushing tube, a control hanging head, an inner sheath tube and a tip end. the inner sheath tube penetrates through the outer sheath tube, and a tip is arranged at one end of the inner sheath tube; a pushing tube is arranged at the tail end of the outer sheath tube, and a control hanging head is arranged at the tail end of the pushing tube; a handle is arranged at the end, close to an operator, of the outer sheath tube; a hanging head switch connected with the control hanging head is arranged on the handle; the handle is further provided with a sliding valve connected with the pushing tube; a gap for mounting the atrial shunt is formed between the outer sheath tube and the inner sheath tube; and the atrial shunt is separated from the atrial shunt conveying device by controlling deformation of the hanging head. According to the atrial shunt system, the heart blood can be shunted, so that the purposes of delaying heart failure and treating heart failure are achieved; and the atrial shunt system is relatively simple in structure and safe and reliable to use.

Description

technical field [0001] The invention relates to an atrium shunt system, which belongs to the technical field of medical instruments. Background technique [0002] Heart failure is the final result of various cardiovascular events and the cumulative effect of various cardiac abnormalities, ultimately leading to a decline in the pumping function of the heart. Cardiovascular patients with clinical manifestations of heart failure have a poor prognosis. The incidence of chronic heart failure is high, and the 5-year survival rate is similar to that of malignant tumors. The more severe the heart failure, the higher the risk of death, which seriously threatens people's health and quality of life. Heart failure is an abnormal change in the structure and function of the heart caused by various reasons, which makes the systolic ejection and / or diastolic filling function of the ventricle dysfunction, thus causing a group of complex clinical syndromes. [0003] In patients with heart f...
