Problems solved by technology

However, the structure of the tube is too complicated, and the practicability is not strong. Firstly, the consumables are increased, and secondly, the tube has a huge risk. The rupture of the balloon will cause a large amount of gas to enter the left atrium, which is the last thing you want to see in heart surgery, because the gas Through the left atrium, the left ventricle will enter the coronary artery, which will be fatal

Abstract

The invention discloses a left heart suction device for the cardiac surgery. The left heart suction device comprises a left heart suction tube and a rolling pump used for forming negative pressure in the left heart suction tube. The left heart suction tube comprises a tube body and a suction head. The suction head is provided with a suction hole. The front end of the tube body is connected and communicated with the suction head through a connector, and the connector is provided with a valve hole and a unidirectional air valve mounting on the valve hole. When the negative pressure in the tube body is increased to a set value, the unidirectional air valve is stressed to be switched on so that outside air can enter the tube body. According to the left heart suction device, the blocked suction tube can recover to be smooth conveniently, the damage to the endocardium caused by the blockage of the suction tube by blood blocks is avoided, and operation safety is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a left heart suction device for cardiac surgery. Background technique [0002] The left heart suction device is an important part in heart surgery. In heart surgery that requires extracorporeal circulation, the blood returned from the upper and lower vena cava is returned to the blood storage tank through the vena cava, and the blood in the operation field is drained back to the heart through the right heart drainage tube. The blood storage tank, the arterial part uses the aortic cannula to infuse oxygenated blood into the aorta, and the pulmonary artery return blood in the left heart is drained through the left heart drainage tube. This is very important, because whether the left heart drainage is unobstructed not only affects the operation field, but also A large amount of blood in the left heart will make the heart full, increase the tension of myocardial cells, and seriously affect the hea...
