Clinical anesthesia intubation auxiliary device

Abstract

The invention relates to a medical instrument, in particular to a clinical anesthesia intubation auxiliary device which is characterized in that a bite block assembly comprises an upper bite block and a lower bite block which are mutually overlapped, a shear fork structure is arranged at the tail end of the bite block assembly, a guide pipe penetrates through a through hole formed in the center of the bite block assembly, and an opening and closing mechanism is connected with the guide pipe and the shear fork structure; the pipe conveying assembly is arranged at the tail end of the guide pipe and connected with the opening and closing mechanism, and the mouth moistening assembly is connected with the opening and closing mechanism. The upper tooth cushion is clamped with the upper teeth of a patient, the lower tooth cushion is clamped with the lower teeth of the patient, the opening and closing mechanism is driven by the guide pipe to be matched with the shear fork structure to separate the upper tooth cushion and the lower tooth cushion which are arranged in the oral cavity of the patient, and therefore the oral cavity of the patient is opened. When the oral cavity of a patient is opened, the opening and closing mechanism drives the tube conveying assembly to act, at the moment, the initial section of the trachea cannula manually penetrating through the guide tube to be conveyed to the throat of the patient reaches the tail end of the gas guide tube, the initial section of the trachea cannula enters the sound channel through the throat of the patient through the tube conveying assembly, and finally the trachea cannula is in the same direction with the respiratory tract.

Description

technical field [0001] The invention relates to a medical device, in particular to an auxiliary device for clinical anesthesia intubation. Background technique [0002] Emergency endotracheal intubation has become an important measure in the process of cardiopulmonary resuscitation and the rescue of critically ill patients with respiratory dysfunction. Tracheal intubation is an important rescue technique commonly used in emergency work, and it is one of the most widely used, most effective and quickest means in respiratory management. [0003] The traditional tracheal intubation fixation method is to place the tracheal tube in the median position of the oral cavity, place the tooth pad between the upper and lower molars, cross and fix with two tapes, wrap and fix the tracheal tube and the tooth pad, and use a white tape around the neck to tie a knot on the face. fixed. [0004] However, due to the approximately 90° angle between the throat of the human body and the oral ca...

AI Technical Summary

Problems solved by technology

[0004] But because there is an angle of approximately 90° between the human throat and the oral cavity, it is difficult to extend the intubated trachea from the oral cavity into the respiratory tract. Therefore, a device that can assist the trachea to enter the respiratory tract is provided. assisting equipments
