Description
Technical Field
The invention relates to a disposable video laryngoscope lens with an endotracheal intubation guide groove and an airway surface anesthesia guide groove, which is applicable to the field of medical appliances.
Background
Video laryngoscopes facilitate exposure of the higher glottis due to the curvature of their laryngoscope blades and the large angle of the front end. Disposable laryngoscope blades can avoid cross-infection. Thus, video laryngoscopes fitted with disposable laryngoscope blades are widely used for general anesthesia endotracheal intubation in current clinical anesthesia practice. However, no disposable video laryngoscope blade with an endotracheal intubation guide groove is seen in the market of medical materials at present, and the video laryngoscope with the disposable laryngoscope blade is used for completing endotracheal intubation by molding an endotracheal tube into a fishhook shape through a tube core. When the video laryngoscope exposes the glottis, the oropharyngeal cavity space is exposed very limited due to the radian of the lens, when the tracheal catheter which is bent to 80 degrees at the front section enters the pharyngeal portion through the oral cavity, the front section of the catheter, particularly the cuff portion, is very easy to be polluted by secretion in the oral cavity, the polluted catheter is placed into the trachea, and the capability of resisting bacterial colonization is reduced due to the fact that the cuff is inflated and then the tracheal mucosa is pressed, so that the incidence rate of tracheal and pulmonary inflammation is finally increased. Furthermore, the use of such a core for endotracheal tube shaping, which is not sterilized during clinical anesthesia practice, also increases the risk of bacterial contamination inside the endotracheal tube. Thus, disposable video laryngoscope blades commonly used in the clinic today may reduce cross-contamination of the oropharynx between patients, but may increase the risk of intratracheal and pulmonary infections in patients. Therefore, the structure of the disposable video lens commonly used at present needs to be clinically improved, and the lower respiratory tract infection caused by the pollution of the tracheal catheter is reduced or even avoided on the premise of not influencing the tracheal intubation operation.
When the glottis of a common laryngoscope is exposed, the laryngeal tissues and muscles are required to be lifted up forcefully to enable local tissues to be subjected to great acting force, the lifting force of the video laryngoscope is only 1/10-1/5 of that of the common laryngoscope due to the radian of a laryngoscope blade, so that the irritation to the root of the tongue and the throat is reduced, the hemodynamics of a patient is more stable, and meanwhile, the occurrence of postoperative pharyngalgia and pharyngeal mucosa hemorrhage is reduced, and the situation is more obvious for a patient with a wakeful intubation. Under the assistance of a video laryngoscope, the surface anesthesia of the mouth and throat parts is carried out by using the laryngeal anesthesia tube, so that the operation of the awake patient for carrying out the oral trachea cannula is simple and easy to implement. Because the laryngeal anesthesia tube is thinner, the bending angle and the direction need to be continuously adjusted during operation, and even an assistant is needed to help to hold the local anesthesia needle cylinder at the tail part of the laryngeal anesthesia tube so as to assist in fixing the direction of the front end of the laryngeal anesthesia tube for local anesthesia spraying. And similar situations with the tracheal catheter exist, such as the front end of the laryngeal anesthesia tube is easy to be polluted by the secretion of the oropharynx part. For this reason, improvement of the structure of disposable video lenses commonly used in clinic is required.
