Description
Technical field
The present invention relates to a kind of gas surface humidification device, be specifically related to a kind of device that dry gas is carried out to surperficial humidifying.
Background technology
Medical science general knowledge is pointed out, human body is lived in the environment that humidity is lower for a long time, can cause a series of health problems such as body immunity decline, nasal mucosa damage, and suffers from the patient of the respiratory tract disease that tracheitis, bronchitis, pneumonia, pulmonary abscess, pulmonary tuberculosis, bronchial asthma etc. are more serious, more responsive to living environment, also higher to the requirement of air humidity.Result of study and clinical practice all prove to only have in the time that air amount humidity reaches 45%-75%, are just conducive to treatment and the rehabilitation of various respiratory tract diseases.For ensureing that people live under health environment, or realize the object for the treatment of respiratory system disease, people can carry out humidification to the oxygen or the air that suck, therefore, and a kind of device that dry gas is carried out to safe humidification of market demand.
The mode that gas humidifying product carries out humidifying to dry gas is in the market divided into into two kinds of water humidifying and surperficial humidifyings, traditional water humidifying that enters is that dry gas is passed into humidification fluid inside, gas clashes into continuously and emerges from the water surface in aqueous water, and then mixes the humidifying method that improves total moisture content in gas with numerous droplets.Because this humidifying method noise is larger, droplet is very easily brought the aerosol in water in air-flow into and is detrimental to health again, is now eliminated gradually.Surface humidifying be dry gas flow through moistening humidifying material surface, take away the humidifying method of steam, the method noiselessness, and thoroughly avoided water humidifying to produce aerocolloidal risk, is a kind of humidifying method of widely promoting at present.
The patent of invention of ZL201010539175.1 discloses a kind of oxygen surface humidifying device, this patent provides a kind of unobstructed cavity gap type aseptic noiselessness oxygen humidifying device, device is provided with main casing, humidification fluid transport portion, humidification fluid storage part, surperficial humidifying part, wherein humidification fluid transport portion utilizes capillary principle that the humidification fluid in humidification fluid storage part is delivered to surperficial humidifying part, make surperficial humidifying part keep moistening, dry Oxygen Flow, through surperficial humidifying part, is brought saturated steam layer Oxygen Flow into and is evenly diffuseed to form moistening oxygen.Breed bacteria when avoiding device long-term storage, has added antibiotic substance in humidification fluid, form liquid antibiotic system.But, exceed product in device outer packaging breakage or the resting period and guarantee the quality the time in particular cases, its inner antibacterial system may lose efficacy, the humidifying surface of surface humidifying part likely produces bacterium colony, now dry oxygen high speed impact humidifying surface, bacterium colony is evoked by high velocity air and brings in Oxygen Flow, once be sucked by human body, will produce infection risk; In addition, when carrying moisture due to humidification fluid transport portion, antibiotic substance in humidification fluid is also transported to surperficial humidifying part with moisture, and deposit gradually on the humidifying surface of surperficial humidifying part, especially in the region of humidification fluid transport portion and surperficial humidifying part junction, deposit even more serious.In the time of the region of dry oxygen high speed impact antibiotic substance deposition, the antibiotic substance of deposition is likely evoked by high velocity air and brings in Oxygen Flow, once be sucked by human body, will produce another kind of infection risk; For ensureing the safety of gas surface slaking process, further improve the technique effect of gas surface humidifying, research staff need to develop one and can avoid above-mentioned risk, address the above problem, the safer reliably stable gas surface humidification device in gas humidifying field.
