Integrated single-double lung ventilation visual laryngeal maskTechnical Field
The invention relates to the technical field of medical auxiliary instruments, in particular to an integrated single-double lung ventilation visual laryngeal mask.
Background
In clinical anesthesia and airway management, laryngeal masks are a widely used ventilation tool, which is suitable for airway management in general anesthesia patients, and can also be used in endoscopic tracheobomy surgery or in combination with bronchooccluders to achieve single lung ventilation. However, existing laryngeal masks have significant limitations in the following clinical setting.
The ventilation switching of the single lung is difficult, if bleeding or tumors in the operation greatly affect ventilation in the tracheectomy, the traditional laryngeal mask can not be quickly converted into a single lung ventilation mode, which can cause insufficient ventilation and endanger the safety of patients.
And the tumor falling risk is that after the tracheal tumor is resected, if the tumor body falls off, the traditional laryngeal mask can not effectively block the tumor body from falling into the deep bronchus, so that the operation risk is increased.
Air leakage during the operation of the lung-swelling, namely, in the operation of the thoracic surgery, when the traditional laryngeal mask combined occluder is used for ventilation of a single lung, the air leakage is easily caused by poor sealing of the laryngeal mask during the operation of the lung-swelling (such as re-stretching of the lung), and the lung expansion effect is influenced.
The visualization is insufficient, the existing visual laryngeal mask generally only provides glottic observation, and the position of the bronchial catheter cannot be monitored in real time, so that the single-lung ventilation positioning is inaccurate.

Advantageous effects
The invention has the following beneficial effects:
This visual laryngeal mask of integrated form single two lung ventilation realizes quick, stable single lung/two lung ventilation mode conversion through the collaborative design of built-in bronchial catheter and laryngeal mask main part, has solved the unable emergent ventilation demand in the coping art of traditional laryngeal mask and can't prevent that the tumor body drops and falls into deep bronchus after the trachea tumour excision problem.
The independent anti-drop cuff can be inflated immediately after tumor resection to form a physical barrier, so that the tumor body is effectively prevented from falling into the deep bronchus, and the risk of secondary operation is reduced.
The channels such as gastrointestinal decompression, bronchoscope operation and the like are integrated, extra instrument insertion in the operation is avoided, and the airway injury and the operation time are reduced.
The laryngeal mask camera monitors the glottis and tumor positions in an omnibearing way through the adjustable observation window, and the micro camera of the bronchial catheter feeds back the intrabronchial condition in real time to guide the accurate insertion of the catheter into the target bronchus.
Of course, it is not necessary for any one product to practice the invention to achieve all of the advantages set forth above at the same time.
