The utility model relates to the technical field of medical auxiliary instruments, in particular to a eustachian tube catheter. The Eustachian tube catheter comprises a first section, a second section, a third section and a connector which are sequentially arranged, the first section is made of thermoplastic elastomer materials, the second section is made of one or more materials of nylon elastomers, polyvinyl chloride, polyurethane, nylon elastomers, polyethylene or silicone rubber, the hardness of the second section is larger than that of the first section, and the third section is made of thermoplastic elastomer materials. The third section is made of materials including but not limited to the materials of the second section, but the hardness of the adopted materials is larger than that of the second section. Namely, according to the Eustachian tube catheter, through the design that the first section is made of the thermoplastic elastomer material, when the Eustachian tube of a patient is dysfunctional or
