Humidifying device and ventilation therapy device having the humidifying device

Abstract

A humidifying apparatus (100) and a ventilation therapy apparatus provided with the same. The humidifying apparatus(100) comprises a fluid storing chamber (110) for storing fluid; a humidifying chamber (120) with an air inlet (121) and an air outlet (122) arranged thereon; a communicating device (130) for connecting the fluid storing chamber (110) with the humidifying chamber (120) to provide the fluid in the fluid storing chamber (110) to the humidifying chamber (120); and a vaporizing device (140) arranged on the humidifying chamber (120) for vaporizing the fluid in the humidifying chamber (120), wherein, the fluid in the fluid storing chamber (110) is stopped from being provided to the humidifying chamber(120) when the fluid in the humidifying chamber (120) reaches a predetermined quantity. The humidifying apparatus (100) always does work on a small part of the fluid in the humidifying process and therefore has the advantages of saving the power consumption, avoiding the waste, accelerating the vapor generation, reducing the hazard of fluid back flow and increasing the use space of the fluid storing chamber.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a humidifying device and a ventilation treatment device with the humidifying device. Background technique [0002] To treat apnea and other breathing disturbances during sleep, patients typically use ventilation therapy devices. Ventilation therapy equipment provides positive pressure breathable gas to the patient through the patient contact parts such as the mask to assist the patient to breathe, treat the patient's breathing disorder, and reduce the consumption of breathing work. [0003] Ventilation therapy devices such as Continuous Positive Airway Pressure (CPAP) or Non-Interventional Positive Ventilation Pressure (NIPPV) devices typically use a fan inside the host to introduce gas and deliver the gas at positive pressure to patient-contacting parts such as breathing masks ). However, this direct introduction of the gas to the patient contacting parts is relatively dry. To ...

Problems solved by technology

However, since each humidification process needs to heat all the liquid in the liquid storage chamber at one time, it leads to large power consumption and waste

In addition, since the air outlet of the main engine of the ventilation therapy equipment is directly connected to the liquid storage chamber of the humidification equipment, the liquid in the liquid storage room is easy to flow back into the main engine, which will damage the fan.

At present, in order to prevent liquid backflow, the method adopted is to lower the maximum usable liquid level of the liquid storage chamber, but this will cause a waste of space in the liquid storage chamber
