Description

Double-mirror display device for difficult trachea cannula

Technical Field

The utility model relates to a trachea cannula technical field, in particular to a double mirror display device for difficult trachea cannula.

Background

The endotracheal intubation is the most effective and reliable method for establishing artificial air passage, and is one technology of setting special tracheal tube through oral cavity or nasal cavity and glottis into trachea, and the technology can provide optimal conditions for eliminating obstruction of respiratory tract, ensuring smooth respiratory tract, eliminating secretion in respiratory tract, preventing aspiration, assisting or controlling respiration, etc. It is often used for the treatment of anesthesia in trachea and critical illness. The difficulty in tracheal intubation refers to the difficulty that a normed anesthetist can easily see the glottis under the direct vision of a common laryngoscope, the naked eye can not see any part of the glottis, and a catheter cannot be inserted into the trachea after repeated and intermittent tracheal intubation attempts, or the tracheal intubation time exceeds 10 minutes. If the patients with difficult tracheal intubation try to perform intubation repeatedly without success, the patients often can cause pharyngeal cavity and laryngeal cavity mucosa tissue damage and bleeding, and pharyngeal cavity soft tissue edema or swelling simultaneously occurs, so that the tracheal intubation difficulty is aggravated, individual patients even develop upper respiratory tract management difficulty, the patients face the dangers of incapability of intubation and incapability of ventilation, anoxic respiratory arrest, botanic people and the like can be seriously caused, and the difficult tracheal intubation always refers to the key and difficult problems which need to be solved urgently by anesthetists.

The visible laryngoscope commonly used for intubation sometimes can not pick up the epiglottis, and the glottis can not be seen after the epiglottis is picked up, so that the insertion of the tracheal catheter can not be known. The disadvantage of this method is that the endotracheal tube is often stuck in the posterior junction of the epiglottis and glottis during the process of sliding inwards along the bronchofiberscope; another method uses a double bronchofiberscope, which is applied in a conscious patient, i.e. a patient with a difficult airway is expected to be under anesthesia after intubation, and the conscious patient has the advantages that the muscle of the patient is tensed, the mandible is not loosened, and although the tongue is also fallen, the inner space of the oral cavity can still be subjected to bronchofiberscope operation. The patient does not breathe spontaneously due to the use of anesthetic, so that the life safety of the patient cannot be guaranteed if the tracheal cannula is not inserted, the repeated intubation may cause edema of tissues around the glottis, and the patient can be quickly lack of oxygen to cause a series of complications if the patient cannot ventilate with the mask. At this time, the lower jaw of the patient is loose, the tongue body falls down seriously, the inner part of the oral cavity does not have enough space for performing the operation of the bronchofiberscope, the double bronchofiberscope loses the advantages in the situation, if the double bronchofiberscope is required to be used, extra people are required to specially lift the lower jaw of the patient, the labor is wasted, and the operation is inconvenient.
