Method and device for controlling respiratory humidifier, respiratory humidifier and storage medium

Abstract

The embodiment of the invention discloses a method and device for controlling a breathing humidifier, the breathing humidifier and a storage medium, and the method comprises the steps that the temperature and relative humidity of an air inlet of a humidifying tank are determined, and the temperature and the air flow set by a user are obtained; based on the temperature set by the user, the gas flow set by the user, the temperature of the gas inlet and the water surface area of the humidifying tank, the water temperature needed by the humidifying tank to output saturated steam corresponding to the temperature set by the user is determined, and heated and humidified gas is generated. According to the scheme, the cost is reduced, the accuracy is better, and condensate water can be prevented from being generated.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a method and device for controlling a respiratory humidifier, a respiratory humidifier and a storage medium. Background technique [0002] In clinical practice, the temperature and humidity of the gas have a great impact on the comfort of the patient. If the patient directly inhales cold and dry air for a long time, it will easily lead to thick bronchial secretions, block the trachea, increase the burden of breathing, and cause lung infection. Therefore, respiratory humidification instruments capable of heating and humidifying gas have appeared on the market at present, and provide mild and humid gas to patients by heating the breathing tube. [0003] However, when this respiratory humidification instrument is used for a long time, condensed water is formed in the air outlet pipeline, which is easy to choke the patient and makes the patient feel uncomfortable and inconvenient to ...

AI Technical Summary

Problems solved by technology

[0003] However, when this kind of respiratory humidification instrument is used for a long time, condensed water will be formed in the air outlet pipeline, which will easily choke the patient and make the patient feel uncomfortable and inconvenient to use.

Therefore, there are two solutions for the existing respiratory humidifier to solve the problem of condensed water: one is to add a condensed water collector (such as a ventilator) on the heating pipe, but this method increases the cost of consumables and is easy to Infection, the pipeline is complicated, and it is inconvenient to use; another is to add temperature and humidity sensors at both ends of the heated breathing tube, and simultaneously detect the temperature and humidity of the gas output from the humidification tank, and detect the temperature and humidity of the gas output from the heating tube; but this This method needs to use multiple temperature and humidity sensors, which is expensive, and the sensitivity, stability, and accuracy of the temperature and humidity sensors are low in high relative humidity environments. This method cannot avoid the problem of condensed water
