Trachea cannula capable of conveniently determining position in airway

Abstract

The invention discloses a trachea cannula capable of conveniently determining the position in an airway, and belongs to the technical field of trachea cannulas. The detection mechanism is installed on the outer side wall of the trachea cannula, an infrared receiving tube and an infrared transmitting tube are installed on the side, facing the air bag, of the detection circuit board, and a power connector is installed at the edge of the side, away from the air bag, of the detection circuit board; an infrared transmitting circuit, an infrared receiving circuit and a voltage amplifying circuit are etched on the side, away from the air bag, of the detection circuit board, and the infrared transmitting circuit and the infrared receiving circuit are both connected to a power connector. Therefore, the requirements of the technology on the proficiency and clinical experience of the doctor are greatly reduced, and the efficiency and the success rate of the tracheal intubation are improved.

Description

technical field [0001] The invention relates to the technical field of tracheal intubation, in particular to a tracheal intubation that can conveniently determine the position in the airway. Background technique [0002] Endotracheal intubation is an important technique to establish an artificial airway, ensure the smoothness of the airway, and meet the body's oxygen supply needs and carbon dioxide excretion. It is also the basic technology of modern emergency medicine and modern anesthesiology; it is a key technology for ventilation support and respiratory therapy; Critically ill patients and cardiopulmonary resuscitation play an important role in rescue and treatment. [0003] Clinically, it is widely used in many departments and departments including respiratory department, emergency department, ICU and so on. Tracheal intubation is the most commonly used method to open the airway in first aid, resuscitation and clinical anesthesia, but due to anatomical and pathological...

AI Technical Summary

Problems solved by technology

A large number of clinical data show that it is most appropriate to fix the end of the cannula at the upper end of the carina about 2cm-3cm. If it is too shallow, it will cause the cannula to fall off, hinder the normal operation, and affect the oxygen supply of the patient's body; if the insertion distance is too deep, it may cause Can enter one side of the bronchi, causing atelectasis on the other side of the patient's lung, which may cause chest pain, sudden dyspnea and cyanosis, and even shock
