Nasal trachea cannula inspectoscope

Abstract

The invention discloses a nasal trachea cannula inspectoscope. The nasal trachea cannula inspectoscope comprises an eye lens, an irradiation light source and a guide catheter. One end of the guide catheter serves as an operation and observation part end, and the other end of the guide catheter servers as a bendable part end. A first operation handle and a second operation handle are arranged at the operation and observation part end, wherein the first operation handle controls a bendable part to be bent front and back, and the second operation handle controls the bendable part to be bent left and right. A divergent optical fiber channel, a focusing optical fiber channel and an observation optical fiber channel are arranged inside the guide catheter, the light outlet end of the observation optical fiber channel, the light inlet end of the divergent optical fiber channel and the light inlet end of the focusing optical fiber channel are all located at the operation and observation part end, the light inlet end of the observation optical fiber channel, the light outlet end of the divergent optical fiber channel and the light outlet end of the focusing optical fiber channel are all located at the bendable part end, the eye lens is arranged at the light outlet end of the observation optical fiber channel, and the irradiation light source is arranged at the light inlet end of the divergent optical fiber channel and the light inlet end of the focusing optical fiber channel. The nasal trachea cannula inspectoscope can accurately guide a trachea cannula to stretch into a trachea, and can detect whether foreign matter or lesions exist inside the trachea.

Description

technical field [0001] The invention relates to a tracheal intubation inspection mirror, in particular to a nasotracheal intubation inspection mirror. Background technique [0002] Endotracheal intubation has become an important measure in cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. Endotracheal intubation is an important rescue technique commonly used in emergency work. It is one of the most widely used, most effective and fastest methods in respiratory management. It is a basic skill that medical personnel must master proficiently. play a vital role. [0003] In clinical practice, the tracheal intubation tube is inserted into the trachea through oral guidance, and the intubation operation is completed, and then a ventilator is connected to the tracheal intubation tube to assist critically ill patients with respiratory dysfunction to complete breathing movements. However, for coma patients, patients undergoing general ...

AI Technical Summary

Problems solved by technology

However, for coma patients, patients undergoing general anesthesia or patients with closed teeth, etc., it is impossible to insert the endotracheal tube into the trachea through the oral guidance, and the endotracheal intubation through the oral cavity has the following disadvantages: the pain caused to the patient Large, affecting the normal eating of patients, and it is easy to cause fatigue of patients during long-term intubation, increasing the chance of oral infection

Although there are some nasally guided endotracheal intubation techniques in the prior art, these techniques often rely on correcting the endotracheal intubation through the mouth so that the endotracheal intubation can be accurately inserted into the trachea, which is difficult to operate
