Abstract
Description
Technical Field
[0001] The utility model relates to the field of ventilator-related products, in particular to a ventilator pipeline condensate water drainage structure. Background Art
[0002] Ventilators are currently widely used in hospitals to rescue and treat patients. When using ventilators, in order to prevent the patient's airway from drying out, active heating humidifiers are used to increase the humidity and temperature of the patient's inhaled gas. Since the ambient temperature is generally lower than the temperature of the gas in the ventilator pipeline, a large amount of condensed water will be generated in the breathing pipeline, and the condensed water will be deposited in the water collecting cup in the middle of the ventilator pipeline. Since the water collecting cup is generally an open structure, it is easy to cause the water collecting cup to overturn when the ventilator is maintained and used. Condensed water is conducive to the growth and reproduction of bacteria, which will not only pollute the surrounding air, but also cause harm to nursing staff. Utility Model Content
