Description

Wireless Visual Double Lumen Endotracheal Tube

technical field

The utility model relates to the field of medical equipment, in particular to a wireless visual double-chamber trachea intubation tube.

Background technique

In clinical practice, ensuring the airway is unobstructed and maintaining normal gas exchange is the first task that must be solved when rescuing critically ill patients such as patients receiving anesthesia, patients with severe trauma, and patients with respiratory and cardiac arrest. The basic guarantee for circulatory and central nervous system resuscitation and rescue of kidney function. It has been reported in the literature that more than 50% of anesthesia-related serious complications are caused by improper airway management, and about 30% of anesthesia-related deaths are caused by failure to manage difficult airways. Therefore, the knowledge and skills of quickly establishing an artificial airway, performing artificial ventilation, and ensuring effective gas exchange play an important role in emergency resuscitation. In order to ensure the patency of the airway, people are constantly researching, exploring, and looking for various new tools to help improve the success rate of endotracheal intubation when the airway is difficult, or when the endotracheal intubation cannot be completed temporarily, certain tools can also be used. tools to ensure effective ventilation of patients.

Endotracheal intubation refers to the technique of inserting a special catheter into the trachea through the glottis. Emergency endotracheal intubation has become an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. The existing endotracheal tube itself does not have a video function. During the intubation process and after the endotracheal tube is inserted, other tools, such as laryngoscopes, video laryngoscopes, video light sticks, endoscopes, etc., are needed to cooperate with direct vision. After the glottis is exposed, a catheter is inserted orally into the trachea. However, these instruments need to be tediously sterilized before being used again, and the equipment is expensive, and many medical institutions cannot afford it.

At present, there is no similar product. The patent CN 201880158 U discloses an improved right double-lumen bronchial tube. The left opening is the same as that of the traditional right double-lumen bronchial tube.
