Temperature and humidity control system for humidifier of respiratory support equipment and control method thereof

Abstract

The invention provides a temperature and humidity control system for a humidifier of respiratory support equipment and a control method thereof, wherein the temperature and humidity control system forthe humidifier of the respiratory support equipment comprises: a humidifier main body, a first temperature and humidity acquisition device, a second temperature and humidity acquisition device, a first heating device, a second heating device, a temperature acquisition device and a humidifying controller. A water box is arranged inside the humidifier main body, the first heating device is used forheating gas in a pipeline of the respiratory support equipment, the second heating device is used for heating water in the water box, the temperature acquisition device is used for acquiring a temperature value of the second heating device, and the humidifying controller is used for receiving the temperature and humidity values acquired by the first temperature and humidity acquisition device andthe second temperature and humidity acquisition device, comparing the received temperature and humidity values with the target temperature and humidity values, and outputting a control signal to thefirst heating device or the second heating device. The invention aims to change the existing temperature control method into a humidity control method in order to control humidity, and partial temperature adjustment is only for humidity control, so that the humidity output to a patient end is constant, and the degree of comfort and the treatment effect of the patient are improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment manufacturing, in particular to a temperature and humidity control system and method for a humidifier of respiratory support equipment. Background technique [0002] A humidifier is usually a device used in conjunction with apnea therapy or other household / medical ventilators. Its function is to provide the humidity level of human breathing gas. It is specified and standardized in the special standard ISO8185 and the domestic standard YY0786. [0003] Humidification capacity is an important indicator of a heated humidifier, which defines the humidification output capacity to be achieved within the specified gas flow range. [0004] Traditional respiratory support equipment is mostly equipped with an electric thermostatic steam generator, and its humidification efficiency is affected by factors such as the amount of inhaled gas, the contact area and contact time of air and water, and wate...

AI Technical Summary

Problems solved by technology

[0004] Traditional respiratory support equipment is mostly equipped with an electric thermostatic steam generator, and its humidification efficiency is affected by factors such as the amount of inhaled gas, the contact area and contact time of air and water, and water temperature. However, most of the current respiratory support equipment is controlled by temperature. The humidity is constant, but the humidity keeps changing. This kind of control method makes it difficult to achieve a comfortable humidity level that is beneficial to the patient.
