Description

Continuous oxygen supply device with atomization humidification function

technical field

The utility model relates to medical auxiliary equipment, in particular to a continuous oxygen supply device with atomizing and humidifying functions.

Background technique

Artificial airway is a gas channel established by inserting a catheter into an organ or directly into the trachea through the upper respiratory tract. and critical surgery for critically ill patients. In clinical work, some patients usually need to undergo tracheotomy when their trachea is intubated for a long time and do not meet the conditions for extubation, and a tracheal cannula is inserted at the incision to meet the patient's oxygen supply needs. However, patients with tracheotomy lose the function of the upper respiratory tract to warm, humidify or filter the inhaled gas, and then phlegm scabs appear, causing airway blockage and increasing the chance of lung infection. At present, there are few humidification devices for patients with tracheal intubation. The existing atomization humidification devices need to use a laryngeal mask or a mask. Long-term use will easily cause the skin around the wound to remain in a moist state and cause inflammation; the laryngeal mask or mask does not have Sputum collection function, the sputum spit out by the patient directly enters the laryngeal mask or mask during the atomization oxygen supply process, which increases the chance of infection of the patient; during the humidification process, medical staff need to frequently observe the patient's potion or water humidification, which increases the nursing workload. Especially the workload of night care.
