Description
technical field [0001] The invention relates to the technical field of medical equipment, and more specifically relates to an air-oxygen mixing module that can be applied in high and cold environments. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] The air mixer is part of the ventilator and its function is to mix air and oxygen. Air mixers in the prior art generally do not have the function of heating the mixed gas, and the ventilator in the high cold e...
