Abstract

The invention provides an adjustable blood vessel ring constriction band, comprising a balloon, a woven outer sleeve, an elongated catheter and a subcutaneous fixed joint. The balloon is in a strip shape, and two ends of the balloon are provided with connecting ring buckles. The knitted jacket is sleeved on the outside of the balloon, the balloon is connected with an elongated catheter, and the other end of the elongated catheter is provided with a fixing joint, and the puncture needle or the subcutaneous fixing joint are connected through the fixing joint. The elongated balloon surrounds theblood vessel and is sutured and fixed by connecting ring buckles at both ends of the balloon. The inner diameter of the annular contraction balloon of the invention can be adjusted by injecting and extracting the liquid in the balloon after suturing the fixing points on both sides; We can measure the pressure in the balloon by connecting the piezometer tube and the piezometer, and measure the pressure of the lateral wall of the annular constriction vessel directly, and then evaluate the hemodynamics of the annular constriction vessel.

Description

technical field [0001] The invention relates to a blood vessel annular constriction belt, in particular to an adjustable blood vessel annular constriction belt, which belongs to the technical field of medical apparatus and equipment. Background technique [0002] In recent years, the success rate of surgery for most congenital heart diseases, including complex and severe diseases, has been significantly improved. For some complex congenital heart diseases, the key to improving the success rate of surgery and long-term curative effect is the use of constriction belts for pulmonary artery surgery. The degree of ring reduction and the adaptability of the patient's cardiovascular system. The traditional constriction belts are ordinary polyester belts or silicone rubber belts with woven mesh belts built-in, both of which are inelastic and cannot be extended and expanded. Once the degree of constriction is determined, it is difficult to adjust according to the patient's hemodynami...
