Humidifier for noninvasive ventilation

Abstract

The invention relates to the technical field of medical breathing equipment, in particular to a humidifier for noninvasive ventilation. The humidifier comprises a bottom case, a heating assembly, a humidifier main body and an upper cover, wherein the humidifier main body is provided with a water box; the heating assembly is fixed at the bottom case; a through hole is formed in the bottom of the humidifier main body; a heating disc of the heater assembly is embedded in the through hole; the heating disc and the bottom of the humidifier main body form the bottom surface of the water box; an air inlet hole and an air outlet hole are formed in the side surface of the water box; the air inlet hole is connected with a flow disturbing device capable of scattering airflow entering the water box. The humidifier for noninvasive ventilation is provided with the flow disturbing device, so that the airflow entering the humidifier can be scattered and fully contacts the water surface in the humidifier; the humidifying effect is good; the integral humidifier main body replaces the separated water box and main body structure in the prior art; the heating effect is better; the structure of the humidifier is simple; the cost is lower.

Description

technical field [0001] The invention relates to the technical field of medical breathing equipment, in particular to a humidifier for non-invasive ventilation. Background technique [0002] As a device with artificial ventilation function, ventilator has been widely used in the treatment of respiratory failure, sleep apnea hypopnea syndrome and other diseases caused by various reasons, and it occupies a very important position in the field of modern medicine. Usually the ventilator needs to be used together with a humidifier. A humidifier is a device that can change the temperature and humidity of the breathing gas. The respiratory tract of a normal human body has a humidifying and warming effect on the inhaled gas, which is an important part of the non-specific defense function of the respiratory system. Physiological heating and humidification is mainly completed in the nasopharyngeal cavity. When the gas reaches the back of the pharynx, the temperature is about 30°C, the...

AI Technical Summary

Problems solved by technology

[0003] The airflow of existing humidifiers enters directly from the air inlet, and the airflow may come out directly from the air outlet without fully touching the water surface. The humidification effect is poor, and the comfort experienced by the user is not enough

In addition, the water tank and the heating component of the existing humidifier are separated, the heating effect is poor, and the structure of the humidifier is relatively complicated, and the production cost is relatively high
