ABSTRACT
Objective Nasal administration,as a common means of treatment of respiratory diseases,may normally cause bronchospasm,cough and other adverse reactions,the efficiency of nasal nebulizers has been criticized as well.This paper aims to develop a medicine atomizing device,pharmaceutically atomized in solving the existing problems,providing a modern instrument for treatment of respiratory diseases by traditional Chinese medicine.Methods The device could prepare medicine by decoction and filtration,which means this unit is divided into two functional modules,medicine preparation and herbal atomization.1 200 W heating plate is placed in decoction unit and is programmed to fit traditional decoction protocol.Steam and ultrasonic nebulised medicine are combined in atomizing unit.Another non-contact infrared heating unit also located in to control the temperature precisely.Different forms of traditional Chinese medicine and different filtration methods were selected to optimize the atomizing effect.Results An implementation of two sequence of filtration enabled optimization of atomizing.After 15 volunteers'trial,this device functioned well on Bama nasal medical protocol,and could effectively avoid the adverse reactions of the traditional way of cold fog atomizing.Conclusions The nasal nebulizer equipment on which Chinese herbal medicine treatments could directly performed,produced atomized mist particle size suitable for nasal treatment,and by generating warm steam to avoid the common clinical administration caused choking to hypoxia and other adverse reactions.Meanwhile,instrument has a friendly interactive feature to meet the clinical requirements for medicine nebulizer treatment.
