A device for testing the humidification capacity of a humidifier

Abstract

The invention relates to a humidifying capability testing device for a humidifier. The device comprises an environment temperature regulating box, wherein the environment temperature regulating box is internally provided with a gas temperature buffer box, a temperature controller, a temperature measuring probe, an air compressor, an electronic balance, an airflow regulating valve, a pitometer and a humidifier to be measured. The testing is carried out in the environment temperature regulating box, and the gas temperature is regulated between 5 DEG C and 30 DEG C by the environment temperature regulating box; the gas temperature can be adjusted between 18 DEG C and 30 DEG C by the gas temperature buffer box; the airflow regulating valve can be used for adjusting the flow speed within a range of 0L / min to 30L / min; after a certain time of testing, the mass differences displayed on the electronic balance before and after testing are respectively recorded, the average temperature and the gas volume of gas of the humidifier are inputted, and finally the humidifying capability of the humidifier is calculated. According to the testing device disclosed by the invention, the testing problem that the environment temperature, the input gas temperature and the input gas flow need to be adjusted in a large scale in the testing process of the humidifier is solved; in addition, the humidifying capability testing device is high in integration and simple and convenient to operate.

Description

technical field [0001] The invention belongs to the field of medical device detection, and in particular relates to a humidification capacity testing device for a humidifier, which is mainly used for testing the humidification capacity of a humidifier. Background technique [0002] A humidifier is a medical device that adds moisture to the inhaled gas of a patient in the respiratory department. It is mainly used to keep the patient's respiratory tract moist and reduce the damage caused by dry respiratory tract when the patient uses the ventilator for a long time or the respiratory tract is insufficient. [0003] Humidification capacity is the core technical index to examine the pros and cons of this type of medical device. The test of this indicator needs to provide different ambient temperatures, humidifier inlet temperature and input gas flow rate, and test the change of humidifier quality, the volume of passing gas and the average temperature of input gas before and afte...
