The invention relates to a novel disposable suction type medicine atomizer. Due to the fact that the structure of an existing liquid medicine atomizer is too simple, the atomization effect of sprayed liquid medicine is greatly affected by airflow generated in breathing, insufficient airflow causes poor atomization effect or insufficient atomization of the liquid medicine, particles of the sprayed liquid medicine is large to make a medicine receiver feel uncomfortable, and feelings of aches and itches are caused. The novel disposable suction type medicine atomizer comprises an atomizing spray head and a base, the atomizing spray head is connected to the base in a sealing mode, an atomization core and an airflow-guiding pillar are arranged in the base, the atomization core is in a frustum shape, an atomization cross beam is arranged at the upper end of the atomization core, the airflow-guiding pillar stretches into the atomization core, the inner wall of the tail end of the airflow-guiding pillar shrinks and is in a conical surface shape, a secondary atomization dam board is arranged in the atomizing spray head, and an atomizing spray head cover is arranged above the secondary atomization dam board.

The invention relates to a novel inhalation preparation, in particular to a preparation suitable for inhalation drug administration of children ranging from 0 to 12 years. After medicine difficult to be dissolved in water and auxiliary materials are mixed, a wet grinding method is adopted for smashing, mixed suspension liquid containing particles with the particle size appropriate is obtained, the particle size is 0.1-7 microns, and preferentially, the particle size is 0.1-5 microns; and further, the preferential particle size is 0.1-3 microns. Solid powder is obtained through a freeze-drying method. Sealing is performed for obtaining the novel inhalation; and before use, the novel inhalation preparation is mixed with liquid suitable for atomization, re-dispersion is performed, and the mixed suspension liquid capable of being used for atomizing inhalation of children is obtained. The preparation is stored and transported in the form of the solid powder, the problem that when a mixed suspension liquid form is adopted, the physical stability and the chemical stability are poor is avoided, the medicine particle size hardly changes, impurity increase is little, and the content hardly changes. Compared with inhalation powder aerosol, the novel inhalation preparation is especially suitable for atomizing medicine administration of children, medicine smaller in particle size can be adopted, and even though under the situations that breathing of an infant is slight and the effective portion deposition rate is low, an ideal medicine effect can also be achieved.
