A therapeutic device for improving the respiration of a patient, with a curved or bent pipe section and a mouthpiece inserted in a first end of the mouthpiece and adapted to provide an easy-to-handle medicinal device by means of which diseases of the airway can be treated, or the pulmonary volume, as well as the pulmonary inhalation performance, of a patient can be improved. This is achieved in that a holding peg connected to the pipe section can be pushed into a second end of the pipe section, and a passage channel disposed in the holding peg which penetrates into the inside of the pipe section, completely or in part, and the holding peg has a flexible hose is attached to it which runs inside the pipe section, the free end of which can move freely in the area of the mouthpiece between inner walls of the pipe section.

The invention belongs to the technical field of medical instruments and provides an inhalation training instrument for pulmonary inhalation administration. The inhalation training instrument comprisesa tank, an inhalation cylinder, a resistance regulator, a flow sensor, a signal converter and a data analysis part. The inhalation cylinder can rotate around the axis of the tank. Along with rotationof the inhalation cylinder, fan-shaped regulating holes in the resistance regulator coincide with different vent holes, so that resistance borne by airflow is regulated, the flow sensor measures actual flow, the actual flow is converted by the signal converter and then transmitted to the data analysis part, the data analysis part calculates inhalation acceleration, inhalation peak flow velocity and inhalation volume according to flow data, and the data are displayed through a displayer of the data analysis part. According to the inhalation training instrument for pulmonary inhalation administration, the data results such as the inhalation acceleration, the inhalation peak flow velocity and the inhalation volume are visualized, a patient is helped to train the inhalation mode, the pulmonary deposition rate of medicine and the uniformity of delivery dosage are improved, and the patient can obtain a better treatment effect in inhalation medicine treatment.

The invention discloses a tea tree oil clathrate powder inhalation and application thereof to treatment of infected pneumonia. Tea tree oil is prepared into clathrate to improve stability and reduce irritation, and water solubility is also improved to achieve suitableness for pulmonary inhalation. The tea tree oil clathrate powder inhalation is excellent in treatment effect on infected pneumonia including bacterial pneumonia and fungal pneumonia and is convenient to carry and use.

The present invention relates to pharmaceutical compositions which are useful in the treatment of diseases where excess mucus is present in the respiratory tract, such as cystic fibrosis and chronic obstructive pulmonary disease. In particular, the invention relates to pharmaceutical compositions for administration by pulmonary inhalation.
