video laryngoscope

Abstract

The invention discloses a visual laryngoscope, which includes a lens, an optical visual system is arranged inside the lens, an illuminating device is arranged at the front end of the lens, the rear end of the lens is connected with a handle, and a battery compartment and a power switch are arranged on the handle for lighting. The device is connected with the battery compartment on the mirror handle and the power switch through wires. The side of the lens is provided with a card slot for the advancement of the tracheal catheter. The card slot extends along the side of the lens from the rear end of the lens to the front end of the lens. The entrance of the tube, the front end of the card slot is located at the curved structure of the lens and is provided with an entrance of a secondary conduit. The slot structure of the present invention is provided with two tracheal tube inlets, which can meet the needs of oral tracheal intubation and nasal tracheal intubation at the same time, avoiding the need for existing nasal tracheal intubation doctors to rely on their experience to distinguish the intubation with the naked eye. The risk of surgery increases the success rate of nasotracheal intubation.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and relates to a video laryngoscope. Background technique [0002] In the areas of anesthesia, first aid, and intensive care, an endotracheal tube is usually inserted into the windpipe by mouth and a ventilator is used to ensure normal breathing. Especially in the field of anesthesia endotracheal intubation is required work. At present, most hospitals in China generally use non-visual anesthesia intubation before surgery. This tracheal intubation is mainly performed with ordinary steel laryngoscopes. Doctors rely on experience to distinguish the position of the glottis with the naked eye. In patients with difficult glottis exposure, surgery will be difficult. In addition, ordinary laryngoscopes are generally used repeatedly, and cross-infection is prone to occur. In view of the above problems, disposable video laryngoscopes are used more and more widely. The existing disposable vide...

Problems solved by technology

[0003] The main purpose of the present invention is to provide a video laryngoscope, which solves the problem that the endotracheal tube cannot be assisted by the slot on the side of the lens when performing nasal anesthesia intubation with the existing video laryngoscope, thus affecting the success of intubation The problem of rate and operation efficiency
