This invention belongs to the field of medical device technology, and specifically relates to a three-stage dilatation balloon for preventing contrast agent leakage. Addressing the problem that existing three-stage dilatation balloons rupture when the operating pressure exceeds the rated burst pressure, resulting in the instantaneous leakage of high-pressure contrast agent into the patient's body, leading to embolism or tissue damage, the following solution is proposed: an outer balloon body, an inner balloon body, a mesh reinforcement layer, a sheath, and a decompression balloon. The inner balloon body is located inside the outer balloon body, and the ultimate expansion diameter of the outer balloon body is larger than that of the inner balloon body. Both are made of different polymer materials, ensuring that the outer balloon body remains intact and forms a leakage-proof barrier when the inner balloon body ruptures. A mesh reinforcement layer is sandwiched between the inner and outer balloon bodies, and the intersection points of the mesh reinforcement layer are discretely connected to the outer wall of the inner balloon body via micro-anchors. This invention achieves automatic emergency storage and manual aspiration and removal of the contrast agent after balloon rupture, solving the safety problem of contrast agent leakage after overpressure rupture of existing balloons.
