Device for assisting breathing aerosol gas and method for regulating breathing aerosol gas

Abstract

The invention discloses a device for assisting respiration aerosol gas and a method for regulating the respiration aerosol gas. When the device is used for inhalation, atomizing gas is triggered to be generated, and the atomizing gas and absorbed air enter the respiratory tract synchronously. A one-way exhalation valve is arranged on an exhalation opening, exhalation resistance is regulated through the one-way exhalation valve, positive end-expiratory pressure is generated, exhalation time is prolonged, the time of the aerosol gas in the respiratory tract is guaranteed, the aerosol gas can be absorbed, and meanwhile gas of the lung can be fully exhaled. An inhalation flow limiter is arranged on a gas inlet connecter, the ratio of the sprayed aerosol gas to non-aerosol gas is regulated through the inhalation flow limiter, proper inhalation flow speed and enough long inhalation time are guaranteed, it is guaranteed that aerosol medicine is fully inhaled into the lung, and the curative effect is achieved.

Description

technical field [0001] The invention relates to a breathing assistance device, in particular to a device for assisting breathing aerosol gas and a method for regulating breathing aerosol gas. Background technique [0002] Aerosol inhalation therapy is one of the common treatment methods in respiratory department. [0003] During aerosol inhalation therapy, the aerosol gas inhaled into the lungs along with the air flow must reach the small airways to exert its curative effect. However, there is an anatomical dead space in the respiratory tract, which refers to the respiratory tract between the oral cavity and the respiratory bronchioles. The gas capacity of the anatomical dead space of a normal adult is 140ml, and the gas capacity refers to the volume of gas that can be accommodated. When inhaling, the gas passes through the anatomical dead space and then reaches the respiratory bronchioles and alveoli. When exhaling, the gas in the anatomical dead space is exhaled first, an...

AI Technical Summary

Problems solved by technology

In the actual aerosol inhalation treatment, the aerosol drugs that have not yet entered the bronchioles and alveoli and enter the anatomical dead space with inhalation are discharged through exhalation without exerting their effect, and the proportion of aerosol drugs entering the bronchioles and alveoli is relatively small, making the The effect of aerosol inhalation therapy cannot be optimized

[0005] It can be seen from the above that the aerosol inhalation treatment in the prior art cannot ensure the full absorption of the aerosol medicine, and lacks an effective device for assisting breathing aerosol gas. Therefore, the prior art still needs to be improved and developed.
