Description

Visual field angle adjustable multifunctional visual laryngoscope

Technical Field

The utility model relates to the technical field of medical equipment, in particular to multifunctional visual laryngoscope with adjustable visual field angle.

Background

Tracheal intubation is an important medical procedure for general anesthesia or rescue resuscitation of patients. Whether the tracheal intubation process is successful or not directly influences the success or failure of general anesthesia or rescue resuscitation.

The visual laryngoscope is widely applied to clinical anesthesia as an auxiliary tool of the tracheal intubation, and particularly, for some patients with difficult intubation by the common laryngoscope, the intubation accuracy is greatly improved, and the intubation difficulty is reduced. However, the current common visual laryngoscope still has the following defects. Firstly, the method comprises the following steps: the visual angle of the lens of most visual laryngoscopes is mostly fixed, can not adjust, still has some patients to expose the glottis smoothly because of the angle does not coincide, and then can't solve the intubate difficulty. Although some products have certain angle adjusting function, the method has the defects of inconvenient operation, poor practicability and the like. II, secondly: visual laryngoscopes are mostly used for difficult airway intubation, and some patients with difficult airway need to be intubated by trachea while being awake. The conscious intubation can cause great stimulation to the patient, and a series of stress reactions can be caused. In order to reduce the discomfort caused by the conscious intubation, it is necessary to gradually anesthetize the surfaces of the oral cavity and the laryngeal part of the pharynx well before the endotracheal intubation. Most of the laryngoscope and local anesthetic injection devices used in clinic at present are two devices, so that ideal surface anesthesia of the throat is difficult to achieve.
