摘要：
Provided are a balloon (100), a balloon connecting structure (200) and a balloon device. The balloon connecting structure (200) is used for being detachably connected to the balloon (100), the balloon connecting structure (200) comprises an outer catheter (220) and an inner catheter (210), wherein one end of the outer catheter (220) is used for being connected to the outside of a self-closing structure (110), and when the outer catheter (220) is subjected to a first external force, the outer catheter (220) can be separated from the self-closing structure (110)； one end of the inner catheter (210) is used for being connected to the inside of the self-closing structure (110), and when the inner catheter (210) is subjected to a second external force, the inner catheter (210) can be separated from the self-closing structure (110)； through the action of the first external force and the second external force, after the balloon (100) reaches a stomach, the balloon connecting structure (200) can be conveniently separated from the balloon (100)； and when the outer catheter (220) or the inner catheter (210) is in a state separated from the self-closing structure (110), the inner catheter (210) is movably arranged in the outer catheter (220) in a penetrating manner. Preferably, after the balloon connecting structure (200) is separated from the balloon (100), the balloon connecting structure and the balloon can be connected together again when necessary in order to facilitate adjusting the volume of the balloon (100).L'invention concerne un ballonnet (100), une structure de raccordement de ballonnet (200) et un dispositif à ballonnet. La structure de raccordement de ballonnet (200) est utilisée pour être raccordée amovible au ballonnet (100), la structure de raccordement de ballonnet (200) comprend un cathéter externe (220) et un cathéter interne (210), une extrémité du cathéter externe (220) étant utilisée pour être raccordée à l'extérieur d'une structure à fermeture automatiq
