Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an external gas mixer for a hydrogen-oxygen breathing machine. Background Art

[0002] A hydrogen-oxygen ventilator is a medical device that is mainly used to provide oxygen assistance to patients during breathing. By adjusting the hydrogen-oxygen mixed gas in different proportions, the hydrogen-oxygen ventilator can help patients absorb oxygen more effectively and effectively improve the treatment effect of respiratory system-related diseases. Hydrogen-oxygen ventilators are widely used in hospital emergency treatment, rehabilitation treatment and other occasions. They have important therapeutic significance for patients with impaired respiratory system function or respiratory diseases.

[0003] The existing external gas mixer for hydrogen-oxygen ventilators does not have a detection mechanism. Without a detection mechanism, the operator cannot accurately understand the ratio of oxygen to air in the mixer, and the adjustment is relatively blind, which may easily lead to an inappropriate mixing ratio. At the same time, if the oxygen concentration of the mixed gas deviates from the normal range, it will cause safety problems such as insufficient oxygen inhalation or oxygen poisoning in patients.
