The application provides a humidification
control system and method for a ventilation therapy device, including a ventilation therapy device main body, a
respiratory humidifier, a heating circuit, and a nasal
oxygen tube, wherein: the ventilation therapy device main body includes a fan and a first controller; The humidifier includes a water tank, a heating plate, a temperature sensor at the inlet of the water tank, and a temperature sensor on the heating plate; among them, the air outlet of the fan is connected to the air inlet of the water tank; the air outlet of the water tank is connected to the air inlet of the heating pipeline The air outlet of the heating pipeline is connected with the input port of the nasal
oxygen tube; the heating pipeline includes a temperature sensor at the inlet of the heating pipeline and a heating control module of the heating pipeline; the first controller makes the
water vapor in the current water tank The
relative humidity of the first mixed
airflow obtained after mixing with the air input by the fan is the target
humidity. The present application ensures that the
airflow inhaled by the patient is a mixed
airflow conforming to the target temperature and
humidity, so as to ensure the comfort of the patient.
