Embodiment Construction

[0026] See attached Figure 1-8 , a nasal endotracheal intubation guide core disclosed by the present invention, comprising an elastic metal guide wire 1 whose front part is preformed into a curved shape, the curvature of the curved part of the metal guide wire 1 can be prefabricated according to needs, the metal guide wire The cable 1 overcoat has a positioning socket cap 2 for being socketed on the mouth of the nasal endotracheal intubation I. The front end of the metal guide cable 1 is fixed with an end cap 3. The head 31 of the end cap 3 is arc-shaped to avoid the end cap. For damage to endotracheal intubation, the end cap 3 includes a spherical head and a tubular tail 32. The tubular tail 32 of the end cap 3 is sleeved on the metal guide wire 1 and can be fixed by welding. The tail of the end cap 3 is connected with a metal The guide wire 1 extends and passes through the traction steel wire 4 of the positioning socket cap 2. The positioning socket cap 2 is provided with a...

Abstract

The invention relates to a nasal trachea cannula guide core. The nasal trachea cannula guide core comprises an elastic metal guide rope, the front portion of the metal guide rope is pre-plasticized into a curved shape, the metal guide rope is sleeved with a positioning sleeving cap, a pipe orifice of a nasal trachea cannula is sleeved with the positioning sleeving cap, an end cap is fixed to the front end of the metal guide rope, and the head of the end cap is in an arc shape. The tail portion of the end cap is connected with a traction steel wire which extends along the metal guide rope and penetrates out of the positioning sleeving cap, the end, penetrating out of the positioning sleeving cap, of the traction steel wire is connected with a traction operation device, a guide ring is arranged at the position, close to the turning point, of the curved part of the metal guide rope, the traction steel wire penetrates through the guide ring, and under the guidance of the guide ring, the traction steel wire is pulled to drive the end cap on the metal guide rope to move along the inner arc-shaped side of the curved part of the metal guide rope. By means of the nasal trachea cannula guidecore, moulding of the nasal trachea cannula is achieved, it is achieved that the angle of the front end of the nasal trachea cannula can be adjusted, the operation of the nasal trachea cannula is easier and more reliable, and the safety and the efficiency of an operation are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to medical devices for nasopharynx and throat, and more specifically to a nasotracheal intubation guide core. 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 glott...
