Left atrium suction tube

Abstract

The invention discloses a left atrium suction tube. The left atrium suction tube comprises a drainage tube body, a spiral air bag fixed to the side wall of the front end of the drainage tube body and an inflation and deflation device communicated with the spiral air bag, wherein a plurality of side holes are formed in the portion, corresponding to a spiral groove of the spiral air bag, of the side wall of the front end of the drainage tube body, and the inflation and deflation device communicates with the spiral air bag through an inflation and deflation tube and air holes located in the side wall of the drainage tube body. According to the left atrium suction tube, after the spiral air bag is inflated, the atrium wall tissue can be opened, left returned blood enters the side holes in the front end of the drainage tube through the spiral groove to be sucked out, the situation that the side holes of the drainage tube are wrapped by the atrium wall tissue is avoided, the problems that the side holes are blocked, and left returned blood drainage is not smooth are solved, the left atrium suction tube is particularly suitable for a child open heart surgery, a good surgery view is created, the surgery time is shortened, and the surgery quality is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a left atrial suction tube. Background technique [0002] The left atrial drainage tube is one of the necessary intubation tubes for open heart surgery. During the operation, the surgeon inserts the catheter into the left atrium of the patient through the atrial septal hole or the right superior pulmonary vein, and connects the roller pump to attract blood from the left heart to the blood storage tank. It can completely attract the blood from the left heart, which is conducive to creating a good surgical field of view, shortening the operation time, improving the quality of the operation, and playing the role of decompression and exhausting of the left heart; When the drainage tube sucks the blood back to the surgical field, the side hole of the drainage tube is likely to be wrapped by the atrial wall tissue, resulting in the blockage of the side hole and poor drainage of...
