Description
Technical Field
The utility model relates to the technical field of visual laryngoscopes, in particular to a novel soft and hard integrated difficult airway visual laryngoscope.
Background
Tracheal intubation is a key step in rescue and general anesthesia, and laryngoscopes are necessary tools. Difficult airways are common clinically and often life threatening for the patient. With the application of visualization technology (a visual laryngoscope and an electronic soft mirror), clinically difficult airways are remarkably reduced, but a few difficult airways cannot be solved by adopting the current tools, and even the use of a visual hard mirror and a soft mirror or the combination of soft and hard mirrors cannot complete the treatment of the difficult airways, because the soft mirror and the hard mirror have advantages and disadvantages.
Visual laryngoscope: the appearance of the visual laryngoscope greatly improves the convenience of the laryngoscope and the success rate of trachea cannula. The visual laryngoscope is a system for the tracheal intubation technology and airway management, and is characterized in that the visual laryngoscope is provided with a visual system on the basis of the original laryngoscope, so that the visual system can observe and monitor the tracheal intubation process, the tracheal intubation process and the tracheal intubation process in real time, thereby improving the convenience of an operator in using the laryngoscope and improving the success rate of intubation; reduces the risks of hypoxia, airway injury and the like in the intubation of patients. In the process of using the visual laryngoscope, the tracheal catheter is required to be sleeved into the tracheal cannula core due to insufficient epiglottis lifting and natural bending of the throat, and the tracheal catheter can slide into the glottis after shaping. But this adds complexity and cost to the endotracheal intubation procedure. At present, a manufacturer uses the tracheal catheter guiding grooves to guide the tracheal catheter into the glottis in the intubation process, but the widths of the guiding grooves cannot be adjusted at present, so that the tracheal catheter cannot adapt to the sizes of tracheal catheters with different pipe diameters, cannot adapt to the widths of the double-cavity tracheal catheters, and causes inconvenience to clinical use due to the fact that the tracheal catheter is too loose or too tight.
Electronic soft mirror: the electronic soft lens is an important tool for solving the difficult air passage at present, but has the biggest defect that the electronic soft lens fails when meeting insufficient space, and meanwhile, when meeting a fuzzy lens such as secretion, blood and the like, a passage, tissues and organs cannot be identified, so that the operation is interrupted, and the advantage of solving the difficult air passage has limitation.
The existing visible laryngoscopes and soft mirrors used clinically have the following defects:
(1) because the fixed size and length influence the clinical treatment effect, the flexibility is lacking;
(2) because of the fixed visual field, in some special patients, the tracheal intubation can not be completed, and the treatment and rescue are delayed, such as the giant tongue, the serious mandibular joint stiffness, the cervical long person and the like;
(3) difficult airway management using bronchofiberscopes suffers from posterior pharyngeal wall obstruction and no discontinuities are a high failure rate;
(4) the condition that the laryngoscope combined with the bronchofiberscope cannula cannot expose the laryngopharynx cavity and the glottis happens sometimes;
(5) there are also soft and hard integrated tools, but the structure and use of the tool are inconvenient, and the tool can not be widely applied in clinic, and can not really solve the clinical problem.
