Description
Technical Field
The invention relates to the field of medical equipment, in particular to an aerosol intelligent auxiliary drug delivery device based on human inhalation flow and a working method thereof.
Background
The existing slow-resistance lung patients in China are more than 1 hundred million people, and the asthma patients are more than 4570 ten thousand. Both are currently incurable, and symptoms can only be relieved by short-acting β2 receptor agonists and drugs such as inhaled glucocorticoids. The slow lung obstruction and asthma are mainly administrated by inhalation and oral administration, wherein the inhalation administration is the preferred administration route because of the advantages of direct effect on respiratory tract, quick effect, small required dosage and less systemic adverse reaction. Metered dose inhalation aerosols are one of the most common modes of administration by inhalation.
The quantitative inhalation aerosol is a preparation which is prepared by packaging raw medicines, additives and proper propellants together in a pressure-resistant container with a special valve system, spraying out the content in a mist form by the pressure of the propellants when in use and is used for pulmonary inhalation or directly spraying to mucous membranes and skin of a cavity. The disadvantage of metered inhalation aerosols is the high rate of deposition of the drug on the oro-laryngeal side and the high requirements for the inhalation-compression coordination of the patient. The lung deposition rate of the medicine is usually only 5% -20%, and the reason is that the mouth and throat deposition rate of the medicine is high, which not only reduces the treatment effect of the aerosol, but also can cause throat irritation, cough, hoarseness and oropharyngeal candida infection.
Studies have shown that the rate of deposition of aerosol on the oro-laryngeal side is increased and the rate of drug delivery is reduced due to the difficulty of the patient in the coordination of inhalation-compression and poor spray angle and timing.
