Visible laryngoscope

Abstract

The invention discloses a visible laryngoscope which comprises a lens. An optical visible system is arranged in the lens, the front end of the lens is provided with a lighting device, the rear end of the lens is connected with a laryngoscope handle, the laryngoscope handle is provided with a battery compartment and a power switch, the lighting device is connected with the battery compartment and the power switch on the laryngoscope handle through wires, the side face of the lens is provided with a clamping groove allowing a tracheal catheter to advance, the clamping groove extends to the front end of the lens from the rear end of the lens along the side face of the lens, the rear end of the clamping groove is provided with a main catheter inlet, and an auxiliary catheter inlet is formed in the position, located at the bent structure of the lens, of the front end of the clamping groove. According to the visible laryngoscope, the clamping groove structure is provided with the two tracheal catheter inlets, the requirements of orotracheal intubation and nasotracheal intubation can be met at the same time, surgical risks caused due to the fact that an existing doctor for nasotracheal intubation distinguishes through the naked eyes and conducts intubation according to experience are avoided, and the success rate of nasotracheal intubation is increased.

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
