Bidirectional right-angle vena cava drainage tube

Abstract

The invention relates to a bidirectional right-angle vena cava drainage tube. A main body is a thin tube, and a drainage tube orifice bent at a right angle is arranged at one end. The bidirectional right-angle vena cava drainage tube is characterized in that a through hole is formed in the back position of the right-angle bend. The defect that a traditional drainage tube can be only used for achieving single-sided drainage of the vein is overcome, the bidirectional drainage purpose is achieved through the through hole formed in the back portion of the right-angle bend, the tube insertion position can be changed from the right atrium inlet position of the original vena cava to the brachiocephalic vein position, an enough space is reserved for the superior vena cava, and the bidirectional right-angle vena cava drainage tube is smooth in drainage.

Description

Technical field: [0001] The invention belongs to the field of medical equipment, in particular to a bidirectional right-angle vena cava drainage tube. Background technique: [0002] In cardiopulmonary bypass surgery, a right-angled vena cava drainage tube is routinely placed at the place where the superior vena cava enters the right atrium to drain the blood from the upper body. In some cases of special operations in children with superior vena cava operation, such as Gleen (caval-pulmonary artery bidirectional shunt), TAPVC (total anomalous pulmonary vein drainage), the conventional method is to place a right-angled vena cava at the place where the superior vena cava enters the right atrium. After intubation, the remaining space is small, resulting in defects such as insufficient length, poor exposure, and difficult anastomosis. If the right-angle vena cava drainage tube is placed at the innominate vein, the above problems can be solved, but the structure of the convention...
