The utility model relates to the technical field of nasal
medical instruments, and discloses a
nasal irrigation device capable of conveniently controlling
irrigation dosage, which comprises a shell, a
catheter connected to the bottom of the shell, and a spray head connected to one end, far away from the shell, of the
catheter, a first cavity and a second cavity are formed in the shell, and the first cavity is communicated with the second cavity. And an elastic mechanism is arranged on the inner top wall of the first cavity. According to the
nasal irrigation device capable of conveniently controlling the
irrigation dosage,
medicine in a second cavity can be squeezed to a spray head through a
piston by pressing a
handle, then
medicine is sprayed to a
nasal cavity, when a certain amount of
medicine is sprayed, a positioning key can move to a positioning hole to be connected with the shell in a clamped mode, and a positioning rod and the
piston can be fixed; the situation that the liquid in the
nasal cavity is sucked into the device to pollute the device due to springback of the
piston can be effectively prevented, the spray head can be conveniently disassembled and assembled in the mode that the guide
pipe is in threaded connection with the spray head, and then the spray head can be conveniently replaced and cleaned.
