The present invention relates to assembly and development of a manually operated mechanical system capable of generating aerosols by nebulization of drug solutions for inhalation purposes. In the present invention the assembly however does not require an electricity or battery operated air compressor, which is an inseparable part of the conventional systems. It can be used to deliver drugs to the lungs and the respiratory tree in a fashion similar to the electricity-operated system. The system is capable of use in treatment of respiratory diseases (like asthma, bronchitis, bronchiolitis, pneumonitis, COAD, pulmonary tuberculosis and cancer lung etc) similar to the conventional commercially available nebulizer systems. It can therefore be used to deposit drugs like salbutamol, salmetrol, steroids, surfactants, and ipoproteum etc through the inhalation route. The assembly system of the present invention is of significant medical importance particularly in areas and times when there is no electricity and more particularly for unconscious or severely ill patients, where it can prove life-saving.
