Description

Multifunctional nasopharynx air duct

Technical Field

The utility model relates to the technical field of medical equipment, especially relate to a multi-functional nasopharynx pipe of ventilating.

Background

As a commonly used rescue means in emergency treatment, the tracheal intubation is one of the most widely applied, most effective and most rapid means in respiratory tract management, and is the basic skill which must be mastered by medical staff. The literature reports that the incidence of difficult intubation is between 1.5% and 13%, and difficult intubation is more likely to occur in sub-optimal environments outside of the operating room, such as emergency rooms, Intensive Care Units (ICUs), patient rooms, and even outside hospitals. Nasal conscious intubation is the most effective method for treating difficult airways.

In the process of trachea intubation, due to the structural characteristics and design defects of a trachea intubation catheter, complications such as laryngeal edema, glottic injury, oral injury, respiratory tract injury, local bleeding and the like can be caused, and the adoption of visual trachea intubation is a good choice in order to reduce the occurrence probability of the complications.

After the tracheal cannula is used for anaesthetizing a patient before an operation, in clinical use, sputum is possibly adhered to the wall of an tracheostomy airway for a long time and is excessively accumulated to form sputum scab due to multiple reasons of insufficient dampness in the cannula, improper sputum suction method, patient expectoration weakness, insufficient body fluid and thick sputum. The current clinical approach to this situation is: 0.5ml of normal saline is dripped into the opening of the tracheal cannula, and then the secretion in the airway and the cannula is sucked out from the near to the far along the tracheal cannula by a sputum suction tube. Because the inner diameter of the tracheal cannula is circular, and the length of the tracheal cannula reaches 250mm and a certain radian, the dropped physiological saline flows from a high position to a low position; meanwhile, the secretion stuck on the tracheal wall cannot be sucked at will, and effective cleaning cannot be achieved.

At present, the nasal endotracheal intubation clinically is conducted through a visual laryngoscope or a fiber bronchoscope for guiding intubation, the operation is complex, the cost is high, and the nasal endotracheal intubation is difficult to popularize in a plurality of primary hospitals. Moreover, the function of the existing endotracheal tube is not complete enough, medical staff may need to use different instruments to perform operations step by step to perform sputum aspiration, gas monitoring and the like when performing intubation-related operations, the steps are complicated, and infection may be generated or the incidence rate of other complications may be increased in the process.
