Nasotracheal intubation device

Abstract

The invention relates to a nasotracheal intubation device. The nasotracheal intubation device comprises a nasotracheal tube and a guide core, the guide core comprises an elastic metal guide rope of which the front portion turns to a curve after preplasticizing, a positioning sleeve connection cap for sleeving a pipe mouth of the nasotracheal tube sleeves the metal guide rope, and the positioning sleeve connection cap is adjustably arranged outside the metal guide rope; an end cap is fixed to the front end of the metal guide rope, the head of the end cap is in an arc shape, a traction steel wire which extends along the metal guide rope and penetrates out of the positioning sleeve connection cap is connected with the tail portion of the end cap, and a traction operation device is connected with the end, penetrating out of the positioning sleeve connection cap, of the traction steel wire; a guide ring is arranged on the portion, close to a turning point, of the curve portion of the metalguide rope, and the traction steel wire penetrates through the guide ring and pulls the traction steel wire under the guidance of the guide ring to drive the end cap on the metal guide rope to move around the inner arc side of the curve portion of the metal guide rope. By the adoption of the nasotracheal intubation device, a transnasal tracheal catheter is shaped, and the angle of the front end ofthe transnasal tracheal catheter can be adjusted, so that nasotracheal intubation operation is simpler and more reliable, and the surgical safety and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to medical devices for the nasopharynx and throat, more specifically a nasotracheal intubation device. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis, which is called endotracheal intubation. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. . Existing methods of tracheal intubation include oral intubation and nasal intubation. [0003] Nasotracheal intubation is a method of tracheal intubation used by anesthesiologists to meet surgical requirements. During nasal endotracheal intubation, when the endotracheal tube passes through the nasal cavity and reaches the glottis, there will be a certain angle between the opening of the endotracheal tube and the glottis, whi...
