In an endoscopic balloon that is connected to an air supply/exhaust pipe for taking air in and out, the root side of the warped portion of the tube-side end of the air supply/exhaust pipe is aligned along the axial direction of the balloon body. An endoscopic balloon characterized in that it is cut with a tube.

Claims

[Scope of utility model registration request]

Both ends of the inflatable outer tube are attached to the outer periphery of the inner tube to form the insertion section of the endoscope and the balloon body which can be fitted externally, and the attachment section is used for introducing and removing air into and out of the balloon body. In an endoscope balloon formed by connecting an air supply/exhaust pipe, the root side of the curved portion that occurs at the tube side end of the air supply/exhaust pipe is cut along the axial direction of the balloon body. balloon.
