Description

A tracheal tube type constant temperature atomizing inhaler

technical field

The utility model relates to the field of medical instruments, in particular to a tracheal catheter type constant temperature atomizing inhaler.

Background technique

Indications and humidity and temperature standards for airway humidification At present, clinical airway humidification is common in patients with airway bypass (tracheal intubation or tracheostomy). Due to the complete loss of humidification and warming function of the upper airway in these patients, the incoming gas must be fully humidified and warmed. The humidifier output power needs to be at least 30mg/L (equivalent to 100% relative humidity at 30°C), which is considered to be the minimum humidity requirement to prevent airway secretions from scabbing and mucosal damage, but it is worth noting: here The proposed humidifier output power standard does not refer to the humidity of the gas entering the patient's lungs. The gas will cool during the pipeline transmission process. As the temperature decreases, the absolute humidity also decreases, and the humidity and temperature reaching the lungs cannot be determined. .

In 2006, the relevant guidelines of the Critical Care Professional Committee of the Chinese Medical Association put forward that the airway humidification standard commonly used in clinical practice is formulated according to the comparison of the airway airway temperature level between the intake part of the respiratory system and the normal airway temperature. Medical gas passes through tracheal intubation or tracheal cannula, the temperature in the airway is 32-37°C, and the relative humidity is 95%-100% (absolute humidity 36-40mg/L). If the temperature and humidity are lower than the above levels, humidity will be generated. Absence, above this level, fluid overload and patient discomfort may occur.
