Embodiment 1
[0028] see figure 1 , 2In this embodiment, the balloon with controllable flow rate in the body for reducing ischemia-reperfusion injury includes: a tail joint 1, a hard push tube 2 (a metal push tube is used in this embodiment), a perfusion hose (including a proximal soft tube) Tube 3 and distal hose 6), balloon 5, guide wire 7 and flow control components; the perfusion hose is a double-layer tube structure. There is a first pressurized chamber 9 inside the metal push tube 2, and a second pressurized chamber 10 inside the inner tube of the perfusion hose. The two communicate with each other to form a complete pressurized chamber. The first pressure chamber 9 is a hollow cavity along the central axis of the metal push tube 2, and the second pressure chamber 10 is a hollow cavity arranged in the perfusion hoses 3, 6, and one end thereof is connected to the first pressure chamber. Cavity 9 communicates, and the other end is provided with a pressure hole at the position where th...
