Although the working section of the balloon in the above patent application has soft villi-like protrusions on the surface, which can make the balloon and the blood vessel have a buffering contact effect, while blocking the blood flow and reducing the damage to the vascular endothelium, the villi arranged on the surface of the balloon are easy to cause blood vessel contamination during the process of balloon advancement, resulting in the problem of low balloon use effect. For this reason, a high-safety vascular balloon blocking emergency device is proposed. Summary of the invention

[0009] As a further solution of the present invention: the end of the first conduit away from the second conduit is fixedly connected to a connecting pipe, the connecting pipe is arranged to be connected with the first conduit, the end of the connecting pipe away from the first conduit is fixedly connected to the first ventilation pipe, the second ventilation pipe, the third ventilation pipe and the fourth ventilation pipe, the first ventilation pipe, the second ventilation pipe, the third ventilation pipe and the fourth ventilation pipe are respectively connected with the connecting pipe.

[0010] As a further solution of the present invention: the first ventilation pipe and the second ventilation pipe are located on the same side of the connecting pipe, and the first ventilation pipe and the second ventilation pipe are arranged in parallel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the second capsule layer is arranged in a concave shape and placed on the first capsule layer, and the thickness of the second capsule layer is thinner than that of the first capsule layer, so that the first capsule layer can drive the expansion of the second capsule layer when it expands. When the balloon member is extended to the corresponding position of the blood vessel, the expansion of the first capsule layer drives the expansion of the second capsule layer. Since the second capsule layer is arranged in a ring shape on the first capsule layer, when the second capsule layer expands, the first villi arranged on the outer surface of the second capsule layer can block the blood vessel and reduce the symptoms of vascular bleeding. On the basis of the second capsule layer, an annular third capsule layer is arranged on the first capsule layer, and the concave degree of the second capsule layer is 1 / 2 of the concave degree of the third capsule layer. Therefore, the first villi on the second capsule layer contact the inner wall of the blood vessel earlier than the second villi on the third capsule layer, thereby achieving a double-layer barrier effect.

[0015] 2. The first ventilation tube and the second ventilation tube are located on the same side of the connecting tube, the first ventilation tube and the second ventilation tube are arranged in parallel, the first ventilation tube and the second ventilation tube are arranged at 45 degrees to the first catheter, the center line of the third ventilation tube and the center line of the first catheter are on the same horizontal line, the fourth ventilation tube is located below the connecting tube, and the fourth ventilation tube is arranged at 45 degrees to the first catheter, so as to realize multi-angle inflation of the balloon, thereby facilitating the expansion of the balloon component and facilitating the balloon component to clear blockages at different angles in the blood vessel.

[0028] It should be noted that during medical use, the expansion operation of the balloon component 20 is performed through the first ventilation tube 121, the second ventilation tube 122, the third ventilation tube 123 and the fourth ventilation tube 124. The setting of the endoscopic probe can observe the specific operation process. The first ventilation tube 121 and the second ventilation tube 122 are located on the same side of the connecting tube 12, and the first ventilation tube 121 and the second ventilation tube 122 are arranged in parallel. The first ventilation tube 121 and the second ventilation tube 122 are both arranged at 45° to the first catheter 10. The center line of the third ventilation tube 123 and the center line of the first catheter 10 are on the same horizontal line. The fourth ventilation tube 124 is located below the connecting tube 12, and the fourth ventilation tube 124 is arranged at 45° to the first catheter 10, so that the balloon 20 can be inflated at multiple angles, thereby facilitating the expansion of the balloon component 20 and facilitating the balloon component 20 to clear blockages at different angles in the blood vessel.

[0029] Balloon 20 Example 1: Figure 1-Figure 4As shown, the balloon member 20 includes a first balloon layer 201, the first balloon layer 201 is wrapped on the outer surface of the second catheter 11, both sides of the first balloon layer 201 are adhered to the outer surface of the second catheter 11, an annular second balloon layer 202 is arranged on the first balloon layer 201, the second balloon layer 202 is arranged in a concave shape on the first balloon layer 201, and the thickness of the second balloon layer 202 is thinner than that of the first balloon layer 201, and the outer surface of the second balloon layer 202 is covered with a first villi 203.

[0030] It should be noted that the second balloon layer 202 is arranged in a concave shape and placed on the first balloon layer 201, and the thickness of the second balloon layer 202 is thinner than that of the first balloon layer 201, so that the first balloon layer 201 can drive the second balloon layer 202 to expand when it expands. When the balloon member 20 is extended to the corresponding position of the blood vessel, the expansion of the first balloon layer 201 drives the second balloon layer 202 to expand. Since the second balloon layer 202 is arranged in a ring shape on the first balloon layer 201, when the second balloon layer 201 expands, the first villi 203 arranged on the outer surface of the second balloon layer 202 can block the blood vessel and reduce the symptoms of vascular bleeding.

[0031] Balloon 20 Embodiment 2: Figure 5-Figure 8 As shown, the balloon component 20 includes a first balloon layer 201, which is wrapped on the outer surface of the second catheter 11, and both sides of the first balloon layer 201 are adhered to the outer surface of the second catheter 11.

[0032] It should be noted that, similarly, on the basis of the second capsule layer 202, an annular third capsule layer 204 is arranged on the first capsule layer 201, and the depression degree of the second capsule layer 202 is 1 / 2 of the depression degree of the third capsule layer 204. Therefore, the first villi 203 on the second capsule layer 202 contact the inner wall of the blood vessel earlier than the second villi 205 on the third capsule layer 204, thereby achieving a double-layer barrier effect.
