Abstract:
Objective To develop a novel automatic water system for ventilator humidifier.Methods By hanging the infusion apparatus high,sustained water was filled by driving force of gravity.Liquid level in the thong of the infusion apparatus was detected by the sensor,and the closing and opening of the closing clip was controlled by solenoid valve.Results The closing clip opened when the liquid level inside the ventilator humidifier fell below the lowest setting value and purified water in the infusion bottle automatically flowed to the humidifier.When the liquid level reached the highest setting level,the closing clip was automatically closed.Conclusions The developed automatic water system for ventilator humidifier is effective,convenient,inexpensive,and realized a sustained,relatively steady and a small amount of water process.Meanwhile,humidifier water is stable,heating is uniform,and gas temperature is relatively constant,which can be applied in clinical use.
