Inhalation-free nasal feeding tube injector

The invention discloses a suction-free nasal feeding tube injector, which relates to the technical field of medical treatment, and comprises a containing device, the upper end of the containing device is movably connected with a connecting device, and the upper end of the connecting device is fixedly connected with a positioning device. By arranging the telescopic pipe, the connecting pipe is connected with the nasal feeding pipe, meanwhile, negative pressure attraction force generated through a first gear ring, a magnetic suction plate, a second rotating block, a second rotating groove, a magnetic suction groove, a magnetic suction ring and a turbine fan is used for sucking food slurry water entering the protection cylinder through a plurality of suction holes through a suction pipe; and then the food slurry is conveyed into the nasal feeding tube through the telescopic tube and the connecting tube to feed a patient, so that the problems that most nasal feeding tube injectors at present are not provided with
