Description

Atomization, humidification and disinfection system for hyperbaric oxygen chamber Technical Field The invention relates to the technical field of medical appliances, in particular to an atomization humidification and disinfection system of a hyperbaric oxygen chamber. Background The hyperbaric oxygen chamber is a core medical device for hyperbaric oxygen therapy, and by constructing a sealed treatment environment which is higher than atmospheric pressure, a patient can inhale high-concentration oxygen so as to obviously improve the blood oxygen partial pressure and increase the blood oxygen and tissue oxygen content, further improve the oxygen diffusivity and the effective diffusion distance, and finally realize the treatment purpose of diseases such as ischemic and anoxic diseases, decompression diseases and the like. The technical design of the existing hyperbaric oxygen chamber mainly focuses on two main core treatment parameters of oxygen concentration regulation and air pressure maintenance, and has obvious defects in consideration of key comfort indexes such as humidity in the chamber. In the hyperbaric oxygen treatment process, the high concentration oxygen environment in the cabin is easy to cause the air humidity to be reduced, and the relative humidity in the cabin is usually reduced to below 30 percent. In such a low humidity environment for a long time, the problems of airway mucosa dryness, throat discomfort, skin dehydration and the like are easy to occur to patients, and symptoms such as cough, nasal hemorrhage and the like are easy to be induced to partial sensitive patients, so that the treatment comfort is reduced, the treatment compliance of the patients is also influenced, and the smooth implementation of a treatment scheme is not facilitated. In order to improve the humidity environment in the cabin, in the prior art, an attempt is made to directly introduce an ultrasonic humidifier, an evaporation type humidifier and the like for humidification, but the equipment still has the technical defects that the conventional humidifier is driven by electric energy to atomize, such as a high-pressure oxygen cabin with the publication number of CN120078607B, the high-pressure oxygen cabin can humidify the internal environment of the cabin through additionally arranging parts such as an interaction channel, a sealing mechanism and an atomizing mechanism on the main body of the cabin, and can prevent the external environment from communicating with the main body of the cabin to cause the leakage of oxygen, pressure and fog, thereby ensuring the curative effect of the high-pressure oxygen cabin, but also needing to carry out large-scale reformation on the main body of the cabin, if the main body of the cabin is replaced with different brands/models, the parameters of the interaction channel and the driving assembly are required to be redesigned, the common use is not, the compatibility is poor, and a professional manufacturer is required to operate the operation in the reformation process, so that the high-pressure oxygen cabin is difficult to adapt to the high-pressure oxygen cabin with different types of specifications, the use cost is increased, the economy is poor, and meanwhile, the high-pressure oxygen cabin is a high-pressure combustion-supporting environment, and the oxygen is a gas, and the high-pressure oxygen cabin is a fire-resistant to the electric power fan due to the high-pressure oxygen cabin, and the high-pressure oxygen cabin has the safety and stable electric power explosion performance. In addition, there is also the atomizing device to the design of local breathing gas among the prior art, like a high-pressure oxygen cabin internal respiration gas buffering atomizing humidification device of bulletin number CN219208589U, and the device has realized the atomizing humidification of breathing gas through atomizing intake pipe and siphon cooperation, has solved the dry problem of breathing gas in the single face guard, still has obvious limitation: firstly, the scene suitability is narrow, the device is designed only aiming at the low-pressure environment of the single breathing mask, the internal pressure of the single breathing mask is usually less than or equal to 0.02MPa, the whole structure of the device comprises a container, a pipeline and the like which are designed to be used locally around low pressure, the full cabin high-pressure environment of 0.1MPa-0.3MPa of a high-pressure oxygen cabin is not considered, namely, under the full cabin high-pressure environment, the related structure of the device cannot bear high-pressure impact, the sealing failure is easy to occur, and the component adapting to low pressure is difficult to resist high pressure, so that the atomization function is interrupted, the oxygen leakage is easy to be caused, and the potential safety hazard is brought to the high-pressure oxygen treatment; secondly, coverage is limited, mist of the device is d
