Output and measurement system and method for humidifying amount of breath humidifying treatment instrument

Abstract

The invention provides an output and measurement system for the humidifying amount of a breath humidifying treatment instrument. The system comprises a breath humidifying treatment instrument host, ahumidifier, a water storage container, a conveying mechanism, an air inlet air channel and a warming breathing pipeline. The air inlet air channel is provided with a flow sensor and a humidity sensor,a water flow sensor is arranged on the conveying mechanism, and the breath humidifying treatment instrument host is provided with a microcontrol unit. Compared with the prior art, the output and measurement system for the humidifying amount of the breath humidifying treatment instrument is simple and effective, and realizes real-time and accurate output and measurement. An output and measurementmethod for the humidifying amount of the breath humidifying treatment instrument is concise and effective in step and high in measurement precision.

Description

technical field [0001] The invention relates to the technical field of humidification volume control of a respiratory humidification therapeutic instrument, in particular to a humidification output measurement system and method of a respiratory humidification therapeutic instrument. Background technique [0002] Respiratory devices (such as respiratory humidifiers) generally have the ability to change the humidity of breathable gas in order to reduce patient airway dryness and patient discomfort and related complications caused by airway dryness. The use of a humidifier placed between the flow generator and the patient generates humidified air that minimizes drying of the nasal mucosa and increases patient airway comfort. [0003] According to national standards and other relevant regulations on the requirements of respiratory device-related products, it is necessary to measure the humidification output of the respiratory humidification therapeutic instrument, but the respir...

Problems solved by technology

[0003] According to national standards and other relevant regulations on the requirements of respiratory device-related products, it is necessary to measure the humidification output of the respiratory humidification therapeutic instrument, but the respiratory humidification therapeutic instrument in the related art does not have convenient, effective, real-time and accurate humidification. The output measurement system and corresponding measurement methods, such as weighing measurement, rely on manual operation and cannot be measured accurately in real time; for example, by setting a temperature and humidity sensor at the humidified gas output end of the humidifier, the structure is complex and cumbersome, and the temperature and humidity The connection structure between the sensor and the respiratory humidification treatment device is inconvenient to set up. Since the temperature and humidity sensor is easy to generate condensation, the design and production of the temperature and humidity sensor are extremely demanding, and the temperature and humidity sensor is easily damaged or the output is wrong. data

Therefore, the humidification volume output measurement system of the respiratory humidification therapeutic instrument in the related art has the disadvantages of complex and cumbersome structure, poor effectiveness, low accuracy, and poor real-time performance of humidification volume measurement.
