Problems solved by technology

[0003] The jet atomization equipment is simple and the atomization effect is good, but at the same time there are also great shortcomings: the atomized drug can be normally inhaled into the respiratory tract when the patient inhales, but the atomized drug is effectively discharged when the patient exhales , not only affects the effect of atomization treatment, but also the utilization rate of the drug is only about 50%, resulting in great waste
Patent No. 201010196906.7 and Patent No. 201010239146.3 also proposed the technical solution of synchronous nebulization, but the core is to guide the patient to passively synchronize with the nebulizer by issuing repeated cross-sound prompts of "exhale~" and "inhale~". The operation requires education and training, and it is inconvenient to use, and it is difficult to effectively synchronize when nebulizing treatment for children or the elderly with poor coordination ability

Abstract

The invention relates to a jet type aerosol inhalation system realizing intelligent medicine control. The system mainly comprises a core control module (1), a respiratory rate sensor (2), an air flow control switch (3), a delay adjustment device (4), an air source input device (5) and a medical vaporizer (6). The system intelligently controls the output of aerosolized drugs to be synchronous with the respiratory rate of a patient, greatly increases the effective inhalation quantity of the drugs, improves the aerosol treatment effect and avoids waste caused by ineffective aerosol discharging of the drugs, thereby having quite high clinical significance and use value.

Description

technical field [0001] The invention relates to an intelligent drug-controlled jet-type atomization inhalation system, which is a medical device used in the treatment process of atomization inhalation in medical institutions or households, and belongs to the category of medical equipment. Background technique [0002] Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The main mechanism of jet nebulization inhalation therapy is to use compressed air or high-flow medical oxygen through a small nozzle according to the principle of Venturi injection. A high-speed airflow is formed, and the negative pressure generated drives the liquid or other fluids to be sprayed onto the barrier together, and splashes around under the high-speed impact to make the droplets of the liquid medicine become mist-like particles and spray out from the air outlet. The drug is inhaled into the respiratory tract to achieve therapeuti...
