Description

Apparatus and method for topical anesthesia and oral distraction for conscious intubation

technical field

The present invention relates to the field of medical instruments and devices, in particular to a device capable of intubating a target subject awake when the target subject is awake and a method for using the same.

Background technique

At present, for those whose airway is difficult to ensure unobstructed, such as intracranial surgery, thoracotomy, prone position or sitting position, etc., general anesthesia surgery is extremely difficult Endotracheal intubation should be performed for obese patients, general anesthetics that significantly inhibit breathing or those who use muscle relaxants. Endotracheal intubation can keep the airway open, facilitate the removal of secretions in the trachea and bronchi, facilitate the implementation of assisted breathing and artificial respiration, and can also reduce the dead space of the airway in patients with respiratory failure, facilitating oxygen inhalation and assisted breathing.

Among them, fiberoptic bronchoscopy is an endoscopic technique with a wide range of clinical applications. Although the operation is not large, it can make many diseases that are hidden in the trachea, bronchi and deep inside the lung difficult to find. Diagnosis and treatment can save many patients from the pain of surgery.

Endotracheal intubation under light anesthesia can cause severe coughing, throat and bronchospasm, rapid heart rate and violent fluctuations in blood pressure, resulting in myocardial ischemia. Severe vagal reflexes can lead to cardiac arrhythmias and even cardiac arrest. Prevention methods include: appropriate deepening of anesthesia, anesthesia of the inner surface of the larynx and trachea before intubation, application of narcotic analgesics or short-acting antihypertensive drugs, etc. According to the current technology, most of the hard material gum pads are used for intubation, and for people without teeth, contacting the hard material between the gums will increase the damage to the gums. In order to reduce the pain of the patient, intubation is performed in the oral cavity after anesthesia. For patients with general anesthesia who have difficult airways, conscious intubation is used under the guidance of a fiberoptic bronchoscope, but the patient's spontaneous breathing should be preserved during the intubation process. , Improve the safety of anesthesia. If the surface anesthesia of the oral cavity and throat is insufficient, the patient will experience nausea, coughing, and breathlessness. It is difficult to insert the fiberoptic bronchoscope into the glottis, and the operating space in the oral cavity is limited. Patients are prone to bite the tracheal tube and fiberoptic bronchoscope.
