The invention discloses a treatment device used for medical wards in the respiratory internal medicine department. The treatment device structurally comprises an atomizing and guiding pipe, an atomizing tank, a driving support, a fixed base, anti-slipping feet, control knobs and an atomizing main unit. The four anti-slipping feet are evenly arranged at the bottom of the fixed base at equal intervals through buckling, and the top of the fixed base and the bottom of the atomizing main unit are buckled. The driving support is arranged and drives an impeller and a driving shaft in a main drive mechanism to rotate through air when an atomizing and air supplying pipeline performs air supplying, then a power source is input into a second drive mechanism, an electricity-conducing mechanism is driven to start a driving device, the driving device drives a stirring device to perform stirring inside the atomizing tank, medicinal powder and water can be rapidly mixed, in this way, it is avoided that the dispersion degree of an atomizing medicament is decreased because the medicinal powder deposits on the bottom, and the effective utilization rate of the medicament is increased.
