Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a coronary artery cardioplegia fluid perfusion device. Background Art

[0002] At present, patients with moderate or above aortic valve regurgitation need to be directly perfused with cardioplegia solution through the coronary artery during heart surgery. However, the leak-proof design of the coronary artery perfusion device currently in common use is fixed and cannot be adjusted, which leads to easy leakage of cardioplegia solution in patients with large coronary artery openings. When surgeons observe cardioplegia solution leakage, they will repeatedly adjust the direction of the perfusion device and the depth of insertion into the coronary artery to prevent leakage. During the adjustment process, the adjustment of the perfusion device will repeatedly rub the coronary artery endothelium, increasing the risk of coronary artery endothelium damage, and there is no guarantee that the cardioplegia solution will actually enter the coronary artery, which will affect the perfusion effect, and may lead to serious consequences such as poor myocardial protection and myocardial damage.

[0003] A direct coronary perfusion tube is disclosed in Chinese patent CN 210992514 U. The direct coronary perfusion tube has the characteristics of preventing leakage during perfusion of cardioplegia solution, reducing the risk of coronary endothelial damage, being simple to operate, and reducing the labor intensity of doctors. However, while solving the problems, the direct coronary perfusion tube has the following disadvantages: the exhaust pipe assembly of the device does not have a device to prevent bacteria and dust from entering the shunt bag. Bacteria are likely to enter the shunt bag through the exhaust pipe assembly and contaminate the internal medicine. The device uses a clamp to squeeze the outer balloon, but the squeezing effect is not good and it is easy to fall off. When the perfusion hole is inserted into the coronary artery, the liquid in the outer balloon will flow back into the inner balloon, which may cause the perfusion hole to be fixed by the inner balloon before it is inserted into the coronary artery.
