Technical Field

Background

Oxygen uptake is also referred to as inhalation of oxygen. It is a treatment method for relieving hypoxia which is commonly used in clinic. The oxygen inhalation aims to improve the blood oxygen content in the body of a patient and the level of the arterial oxygen saturation so as to correct the phenomenon of oxygen deficiency of the patient, finally promote the metabolism of the patient, relieve the mental overdraft and assist in treating various diseases, such as cerebrovascular disease, chronic tracheitis and the like. The oxygen inhalation should be heated and humidified, the temperature of 37 ℃ and the humidity of 95-100 percent in the respiratory tract are necessary conditions for the normal clearing function of the mucociliary system in the trachea, so the oxygen inhalation should pass through a humidifying bottle and a necessary heating device to prevent the dry and cold oxygen inhalation from stimulating and damaging the airway mucosa, causing dry phlegm and affecting the 'clearing doctor' function of the cilia. Patent document CN108066875A discloses a heat-insulating device for an oxygen tube, which only performs the function of heating and heat-insulating, but does not improve the humidification. The humidification bottle is very inconvenient because the humidification bottle needs to be replaced frequently, especially outdoors or in the home. Therefore, designing an oxygen therapy structure with heating and heat preservation functions is an urgent problem to be solved.
