Auxiliary device for difficult trachea cannula

Abstract

The invention relates to an auxiliary device for difficult trachea cannula. The device comprises a trachea cannula body, an inner ring extension tube and an inner ring fixing tube, wherein the inner ring extension tube and the inner ring fixing tube are arranged in the trachea cannula body. One end of the trachea cannula body is a tail end connector, and the other end is a front end insertion opening. The inner ring fixing tube is installed inside the tail end connector of the trachea cannula body through a rotating shaft. One end of the inner ring fixing tube extends out of the trachea cannula body and is connected with an end-expiratory carbon dioxide monitoring device, and the other end is in threaded connection with the inner ring extending tube in the trachea cannula body. The outer side face of the inner ring extension tube and the inner side face of the trachea cannula body are arranged in an attached mode and can slide relatively. The end, away from the inner ring fixing tube,of the inner ring extension tube is arranged at the front end insertion opening of the trachea cannula body, and a micro camera is installed in the end opening through a supporting column. According to the invention, the telescopic length of the inner ring extension tube can be adjusted; the angle of the end of the inner ring extension tube can be adjusted; and end-expiratory carbon dioxide can bemonitored.

Description

technical field [0001] The invention belongs to the technical field of medical airway intubation equipment, and in particular relates to an auxiliary device for difficult airway intubation. Background technique [0002] The management of difficult airway is still one of the most serious challenges anesthesiologists face, and it is closely related to anesthesia safety and anesthesia quality. If it is not managed properly, the normal ventilation of the patient cannot be maintained, which will directly affect the life of the patient. Therefore, how to deal with difficult airway and how to control the ventilation of patients with difficult airway are hot issues that doctors in the field of anesthesia are concerned about. [0003] At present, the auxiliary device for difficult airway intubation is mainly a kind of end-tidal carbon dioxide guided endotracheal intubation device disclosed by CN106902434A. Although it improves the convenience in the process of inserting the difficul...

[0003] At present, the auxiliary device for difficult airway intubation is mainly a kind of end-tidal carbon dioxide guided endotracheal intubation device disclosed by CN106902434A. Although it improves the convenience in the process of inserting the difficult trachea, it does not have the ability to Intuitively displayed equipment and instruments and instruments for clear monitoring of end-respiratory carbon dioxide lead to unclear observation and monitoring values. At the same time, the length of the pipeline is not easy to adjust, which affects the convenience of use
