Patent ID: 8657844

Claim:
A medical expanding apparatus comprising: an expanding member for being expanded in the human body using air pressure; an air tube, whose one end is coupled to the expanding member, for holding the expanding member and for guiding the air into the inside of the expanding member; a connecting part, whose one end is fitted into the other end of the air tube to be tightly coupled to the air tube, for guiding the air into the air tube; a body having an air inflow pipe, for transferring the air flowing in through the air inflow pipe to the connecting part in order to expand the expanding member, wherein one end of the body is coupled to the other end of the connecting part; and a front cover, coupled to the one end of the body, for closely coupling the connecting part and the body, so that the body holds the connecting part; wherein the connecting part is formed with a tapered inner portion through which air passes, so that the expanding member can be expanded by the air at the same pressure as the air flowing in the body.
