Disposable trachea cannula capable of being compressed and inflated manually

Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to a disposable trachea cannula capable of being compressed and inflated manually.

Background

Tracheal intubation is a medical technique widely used in clinical medicine, and is mainly used for establishing an artificial airway so as to facilitate mechanical ventilation and treatment. In emergency situations, such as when the patient cannot breathe spontaneously or has dyspnea for some reason, the tracheal cannula can quickly restore the respiratory function of the patient, so as to fight for further treatment. Furthermore, endotracheal tubes are also commonly used in anesthesia procedures and Intensive Care Units (ICU) to ensure that the patient is adequately supplied with oxygen.

The balloon of the tracheal tube is an important component and is positioned at the distal end of the tracheal tube and can be inflated and deflated. The function of the air bag is mainly to seal the opening of the trachea cannula and prevent sputum, blood or other secretions of a patient from entering the lung. Meanwhile, the air bag can play a certain compression role, and is beneficial to controlling the bleeding of the respiratory tract.

However, the balloon on the existing tracheal cannula has some problems in use.
