Breathing humidifier, dry burning detection method thereof and computer readable storage medium

Abstract

The invention relates to a breathing humidifier and a dry burning detection method thereof and a computer readable storage medium, the breathing humidifier and the dry burning detection method thereof comprise the following steps: 1, controlling the temperature of a heating disc to be maintained at a preset temperature; secondly, the current input power P < total > of the heating disc is substituted into a standard relation between power and temperature to obtain the normal temperature T < disc > of the heating disc; step 3, calculating according to a formula = to obtain a temperature difference delta T; if the delta T is smaller than or equal to the threshold value D, the second step is executed again, and when the delta T is larger than the threshold value D, dry burning is judged; the threshold value D is 4-5 DEG C. Due to the fact that the standard relation between the power and the temperature is adopted in dry burning detection, and the standard relation between the power and the temperature comprises the power loss condition of the heating disc, the quality of the heating disc, the quality of water in the humidifying tank and the initial temperature, the judgment accuracy is high.

Description

technical field [0001] The invention relates to a medical device, in particular to a humidifier of a ventilator, a dry burning detection method thereof, and a computer-readable storage medium. Background technique [0002] Respiratory humidifier, that is, the humidifier for ventilator is an important part of the ventilator. Its function is to warm and humidify the inhaled gas. Good heating and humidification can prevent and reduce the secondary infection of the respiratory tract in mechanically ventilated patients, as well as the stimulation of the cardiopulmonary system, and keep the alveoli moist. At the same time, it can also reduce the consumption of heat and moisture in the respiratory tract, make the airway less prone to phlegm scab, reduce the viscosity of secretions, and promote expectoration. [0003] A respiratory humidifier usually includes a humidification tank and a heating plate. The heating plate is used to heat the humidification tank to vaporize the liquid ...

AI Technical Summary

Problems solved by technology

This dry burning detection method is to directly compare the output power of the heater with the preset power to determine whether it is dry burning, but in practice, there are many factors affecting the output power of the heater, such as the ambient temperature, the contact between the heating plate and the humidification tank As well as the water level in the humidification tank, etc., after the superposition of these factors, it directly affects the accuracy of the judgment conclusion of dry burning, and it is easy to misjudgment
