Abstract

The invention discloses a multifunctional breather valve. The multifunctional breather valve includes a breather valve body, a pipe, and a patient end interface, a spray gas connection port and an exhaust port arranged in the pipe. A one-directional inhalation valve is arranged in the gas-spray gas connection port. A limit board is arranged in the exhaust port. The limit board is provided with a communication port. An expiration resistance adjusting device is arranged for the communication port. The expiration resistance adjusting device includes a one-direction expiration valve, a reset spring and a resistance adjusting device. According to the invention, spray gas can be inhaled into the lung part fully and is output during the inspiration process synchronously, secreta is discharged timely, the pipe pressure is stable under different pressure levels due to noninvasive mechanical ventilation and lung injury caused by over high airway pressure during the mechanical ventilation process is avoided. The multifunctional breather valve is suitable for serving as a one-direction valve for aerosol inhalation treatment, an exhalation valve for shock sputum excretion and noninvasive mechanical ventilation, a cough pressure relief valve during the mechanical ventilation process and a valve for breath muscle exercise.

Description

technical field [0001] The invention relates to the technology in the field of medical equipment, in particular to a multifunctional breathing valve. Background technique [0002] Aerosol inhalation therapy is one of the common treatment methods in the Department of Respiratory Medicine. The aerosol gas inhaled into the lungs along with the air flow must reach the small airways to exert its curative effect. However, breathing has an inspiratory phase and an exhalation phase. When inhaling, the aerosol gas can reach the lungs along the inspiratory airflow. Yes, so that the aerosol gas during exhalation is expelled before it can do its job. In addition, there is an anatomical dead space in the respiratory tract, which is the part of the airway from the mouth to the respiratory bronchioles. The anatomical dead space of a normal adult is 140ml, and there are few differences between individuals. When exhaling, the first exhaled gas is the anatomical dead space. Gas, then, comes...
