Artificial airway temperature and humidity pipeline kitTechnical Field
The utility model relates to a medical auxiliary instrument technical field, concretely relates to warm and humid pipeline external member of artifical air flue.
Background
Normally, nasal cavity, pharyngeal cavity and respiratory tract all have the functions of heating and moistening inhaled air. After the artificial airway is established, inhaled air directly enters the lower respiratory tract without being humidified by the upper respiratory tract temperature, so that the respiratory tract mucosa is dried, the incidence rate can reach 30% -66%, and serious hazards such as airway mucosa injury, ciliary movement limitation, sputum scab blockage, lung infection rate increase and the like are caused. The lower limit of absolute humidity in the airway is 20mg/L, and the acceptable lower limit is 30ng/L in long-term mechanical ventilation, and the international standard is 33mg/L at present, but the standard is difficult to reach by clinical routine flow setting. After trachea intubation or tracheotomy, the upper respiratory tract completely loses the heating, humidifying and filtering functions of gas, the defense function is weakened, if the humidification to the artificial airway is insufficient in nursing work, sputum scab is formed on the artificial airway or the upper respiratory tract, and once the sputum scab is formed, the bronchus can be blocked, so that the airway resistance is increased, and peripheral dyspnea and asphyxia are caused. Therefore, airway humidification is important. Airway humidification refers to a method for heating a solution or water and dispersing the solution or water into superfine particles by an artificial method so as to increase the temperature and humidity in inhaled air and achieve the functions of moistening airway mucosa, diluting sputum, keeping normal movement of mucociliary and clearing.
The humidifying device is divided into an active humidifying device and a passive humidifying device, wherein the active humidifying is to heat and humidify actively by heating a humidifier, namely to heat and humidify the absorbed gas and increase the content of water vapor; the passive humidification is carried out through a heat and humidity exchanger (artificial nose), namely the heat and the moisture in the exhaled air of a patient are stored to heat and humidify the inhaled air. But artifical nose is unsuitable for all patients, easily causes the patient to breathe the difficulty, the utility model discloses not only improved the effect of humidifying and avoided the risk, improved patient's comfort level moreover.
