Medical left ventricular drainage tube

Abstract

The invention discloses a medical left ventricular drainage tube. The medical left ventricular drainage tube comprises a drainage tube body; a main drainage hole is formed in one end part of the drainage tube body; side drainage holes are formed in the side wall at one end of the drainage tube body; a balloon is arranged on each of the sides walls of the drainage tube body on the two sides of the side drainage holes; the two balloons are connected with an infusion connector through an infusion tube; the infusion tube is embedded into the side wall of the drainage tube body; one end of the infusion tube is communicated with the two balloons; the other end of the infusion tube extends out of the side wall of the drainage tube body and is connected with the infusion connector; the infusion connector is also matched with a tapered sealing plug. According to the medical left ventricular drainage tube, the drainage tube body is separated from the left atrium (ventricle) and is not easily adhered to the wall by utilizing the expansion of the balloons; moreover, the drainage tube floats on blood because of density difference, so that the drainage effect is good, the operation is easy to perform, and the medical left ventricular drainage tube is easy to operate.

Description

technical field [0001] The invention belongs to the field of medical surgical instruments, in particular to a medical left heart drainage tube used in heart surgery. Background technique [0002] At present, the left heart drainage tube, which is most widely used in cardiac surgery, is likely to cause the drainage tube to absorb the wall of the left atrium (ventricular) due to the position and other reasons when performing left heart negative pressure suction, resulting in poor drainage and poor surgical field of vision. Clear and repeated adjustment of the drainage tube will prolong the operation time and increase the potential operation risk. Contents of the invention [0003] In order to solve the problems existing in the existing left heart drainage tube, the object of the present invention is to propose a medical left heart drainage tube, by setting a balloon at the end of the drainage tube, and using the support function of the balloon to make the drainage tube and t...
