Document Type and Number:
WIPO Patent Application WO/2021/248581
Kind Code:
A1
Abstract:
Disclosed are a therapeutic humidification apparatus capable of monitoring the mixing of air and oxygen, and a monitoring method thereof, which belong to the technical field of medical machinery. According to the present invention, an ultrasound oxygen concentration sensor is used for real-time monitoring of the oxygen concentration and gas flow output by the therapeutic humidification apparatus; the measurement results are fed back to a system computer in real time; and the system computer regulates an oxygen control module connected to an oxygen inlet and a flow control valve connected to a gas inlet according to the real-time measurement results to jointly regulate the current oxygen concentration and gas output flow of the therapeutic humidification apparatus. When there is an abnormal gas flow or oxygen concentration, the system computer controls the oxygen control module and the flow control valve of the therapeutic humidification apparatus in a timely manner for regulation so as to ensure that the gas flow and oxygen concentration output by the therapeutic humidification apparatus meet the requirements, thereby improving the reliability of the therapeutic humidification apparatus and improving the safety of home-based treatment.
