A drug inhalation device for the upper respiratory tract

Abstract

The invention relates to a medicine inhalator, in particular to a medicine inhalation device for the upper respiratory tract. A T-branch pipe comprises a pipe (5), an air intake and exhaust pipe (6), an inverted-cone pipe (7) and a necking pipe (9). The inverted-cone pipe is arranged at the lower end of the pipe, the necking pipe is arranged at the lower end of the inverted-cone pipe, the air intake and exhaust pipe is arranged on one side of the pipe, and then the T-branch pipe is formed. A medicine inhalation pipe (8) is arranged on the lower portion of the necking pipe, a ball (3) is arranged in the inverted-cone pipe, and the lower end of an inhalation pipe (1) is connected with the upper end of the pipe in an inserted mode. According to the medicine inhalation device for the upper respiratory tract, the ball in the T-branch pipe is utilized to control powder to synchronously enter a nidus portion in the nasal cavity from the medicine inhalation pipe when a patient inhales, the ball closes the inverted-cone pipe communicated with the medicine inhalation pipe when the patient exhales, and therefore the purposes that breath is not affected and the powder is not wasted are achieved.
