Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a heating and humidifying device used for patients who are off-line from respiratory machines. Background Art

[0002] Patients using ventilators in clinical departments undergo off-the-ventilator exercises before being weaned from the machine. Currently, T-tube humidifiers or tracheostomy mask humidifiers (for tracheostomy patients) are commonly used. This type of humidification device does not have a heated humidification function. Cold humidification liquid can easily cause the patient's airway hyperresponsiveness, reducing the patient's weaning success rate. In addition, sterile water in the humidification device needs to be added by medical staff. Excessive addition can lead to excessive humidification, which will reduce the viscosity of airway secretions and dilute surfactants, thereby causing neutrophil infiltration in the lungs and bronchioles, causing excessive secretions, decreased lung compliance, atelectasis, lung infection, etc. Medical staff are busy and cannot add water in time, which will lead to insufficient humidification, resulting in viscosity and retention of airway secretions, serious complications such as lung infection, atelectasis, airway obstruction, and ultimately failure of weaning from the machine. Therefore, those skilled in the art provide a heated humidification device for patients who are off-the-ventilator to solve the problems raised in the above background technology.
