Description

Tracheal catheter

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to endotracheal tube.

Background

In the trachea cannula operation, after the trachea is cut, the upper respiratory tract completely loses the heating, humidifying and filtering functions of gas, the defense function is weakened, sputum scabs are formed on the artificial airway or the upper respiratory tract if the humidification to the artificial airway is insufficient in the nursing work, and the sputum scabs can block the bronchus once being formed, so that the airway resistance is increased, and the peripheral dyspnea and asphyxia are caused. The trachea is easy to be infected when being cut, the tube placing time is too long, the ischemia necrosis of the tracheal mucosa is easy to cause, certain damage or airway blockage is caused to the lung function, and the lung infection rate is increased along with the reduction of the humidification degree of the airway.

The existing humidification mode for patients with tracheotomy clinically is to connect an atomizer with an atomizer connecting cover at the tracheotomy position to humidify an airway, and on one hand, the humidification mode can not ensure that the humidification port can not be completely inserted on a tracheal cannula, so most of mist is lost during humidification, medicine waste is caused, and incomplete humidification easily forms sputum crusts to block the tracheal cannula for replacement; on the other hand, the dressing at the incision is frequently wet due to too large spraying area, bacteria are easy to breed to cause infection, the dressing is repeatedly replaced to cause discomfort of patients, and the nursing cost and the workload of medical care personnel are increased.
