Ventilator humidifier and respiratory humidification treatment device

Abstract

The invention discloses a ventilator humidifier. The humidifier includes an outer shell with an inner hollow, and a water diversion plate divides the outer shell into two independent upper and lower cavities, wherein the upper cavity is a water storage chamber for storing humidifying liquid, and the lower cavity is a humidifying chamber used for evaporating and vaporizing; the plate surface of the water diversion plate is uniformly provided with a fine passage for water to flow downward, and a water control component is arranged above the water diversion plate; the side wall of the humidifying chamber is provided with an air inlet and an air outlet, and an evaporation device is used for heating the humidifying liquid which drips from the upside; the humidifying liquid is heated and evaporated in the humidifying chamber to be mixed with oxygen entering from the air inlet and humidify the dry oxygen. The evaporation device only needs to heat a micro amount of water dripping through the water diversion plate, so that only a small amount of heat needs to be provided to evaporate the micro amount of water so as to achieve the purpose of saving energy. The humidifying chamber and the water storage chamber are isolated from each other, and even if sloshing occurs, the humidifying liquid cannot flow back into an air outlet pipe. The invention also provides a respiratory humidification treatment device which includes the above ventilator humidifier, and the device can achieve the same technical effects.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and further relates to a ventilator humidifier. In addition, the present application also relates to a respiratory humidification treatment device comprising the above-mentioned ventilator humidifier. Background technique [0002] When the ventilator is used alone to treat respiratory diseases, the ventilator outputs dry gas, and the patient is prone to side effects such as dry nose and throat, tongue pain, and even nosebleeds. The humidifier of the ventilator can increase the humidity of the gas entering the lungs, and the additional moisture can make up for the dry tissues of the nose and throat, prevent the above problems from occurring, and make patients feel more relaxed and comfortable breathing. [0003] The current ventilator humidifier heats the humidification liquid in the water box through a heating plate, and the heating plate is installed at the bottom of the heating water...

AI Technical Summary

Problems solved by technology

[0004] This heating method has great disadvantages. To improve the humidification capacity, the working temperature of the heating plate must be increased. Because it heats the liquid in the heating water tank as a whole, it will inevitably increase power consumption, and even the power consumption of the humidifier is greater than that of the humidifier. Power consumption of the ventilator

In order to facilitate maintenance, the traditional humidification water box structure often adopts an opening or a wide mouth, which is difficult to prevent backflow, which increases the risk of humidification fluid flowing backward into the ventilator or tilting to leak
