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 Th

Embodiment Construction

[0028] The present invention provides a device for assisting breathing aerosol gas and a method for regulating breathing aerosol gas. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] The design concept of the technical solution of the present invention is as follows: Since only the aerosol medicine that enters the bronchioles and alveoli and is deposited in the small airways and alveoli can play a role, it is necessary to ensure that the aerosol medicine can enter the respiratory tract with inhalation, and it is also necessary to ensure that the breathing The length of time, prolong the time of a single breath, try to make the breather (person...

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...
