Abstract
A guiding type endotracheal tube mainly comprises a tube 1 and a ventilation joint 2. The guiding type endotracheal tube is characterized in that: the head end of the tube 1 is provided with an arc-shaped curved surface 3; the arc-shaped curved surface 3 integrally has an inwards retreating arc shape; a sharp end 4 has a shape that the ventral surface warps upwards and terminates at the central line position of the pipe body; two sides of the head end of the tube 1 are provided with a pair of circular Murphy holes 5 which respectively have an upper sharp end and a lower circular end; the sharp end of the tube is positioned at the central part and is soft and can be easily bent than the tube body. The guiding type endotracheal tube has a soft sharp end and performs a self guiding function when the endotracheal tube is inserted, thereby reducing endotracheal tube insertion difficulty. When a bougie is used for guiding tube insertion, the upwards wrapped arc-shaped sharp end can be adhibited with the bougie smoothly and closely, thereby facilitating endotracheal tube guiding, improving tube insertion success rate, and reducing damage of throat part, glottis and anterior mucosal of trachea below the glottis by tube insertion. The guiding type endotracheal tube is suitable for tube insertion into trachea through laryngeal mask and tube insertion on the glottis under video laryngoscope.
Description
Technical field
This utility model relates to medical medical instruments field, is specifically related to a kind of clinical artificial airway's of foundation novel tracheal intubation.
Background technology
When the conventional laryngoscope of clinical employing is implemented tracheal intubation, often run into glottis and appear infull situation, as CL classification III or IV level, this moment conventional airway tube the unusual difficulty or easily cause damage of intubate, even severe depletion of oxygen and death take place.
After adopting intubate bougie guidance tracheal intubation and video laryngoscope to improve glottis to appear again intubate can improve the success rate of tracheal intubation.Yet, the method of intubate bougie guiding needs endotracheal tube tip and bougie to fit tightly ability easy importing glottis and does not cause damage, at present conventional endotracheal tube tip is to the side opening, and bougie and endotracheal tube tip are easy to form bifurcated and obstacle intubate and cause damage when guiding.Video laryngoscope widely-used makes glottis appear no longer becomes difficulty, yet but shines into bigger difficulty to tracheal intubation.After adopting video laryngoscope clinically, can see glottis but the sight that inserts the endotracheal tube difficulty occurs again and again, even cause death.Because video laryngoscope all is a laryngeal mirror, making the oral cavity of air flue enter the mouth to the camber of glottis opening obviously increases, and brings difficulty to intubate.
The utility model content
The purpose of this utility model is the guiding type endotracheal tube that designs in order to solve the problem that runs in the above-mentioned intubate, the operation of convenient clinical intubate, grasped by numerous doctors easily and accept, successful intubation is increased, when also having reduced intubate simultaneously to the damage of glottis and trachea antetheca.
Guiding type endotracheal tube mainly comprises conduit and ventilating joint, it is characterized in that conduit adopts the material on flexible soft ground, and joint and conduit junction are detachable.
Described guiding type endotracheal tube, its head end are characterised in that arc-shaped curved surface integral body is the interior circular arc of receiving, and the tip is the outside of belly and is upturned, ends at the body position of center line;
Described guiding type endotracheal tube is characterized in that the head end both sides of conduit are provided with a pair of circular down Mo Feikong of point that presents, and increases most advanced and sophisticated flexibility and makes the tip more flexible, prevents pipe obstruction simultaneously;
Described guiding type endotracheal tube is characterized in that conduit is 90 ° of arc-shaped bends at most advanced and sophisticated 1/3 place;
Conduit integral body of the present utility model has suitable flexibility, has played the effect of self-guiding when tracheal intubation is expert at the tip, has reduced the intubate difficulty; When using the bougie guide cannula, the circular arc that upwarps most advanced and sophisticated can and bougie smoothly, closely paste and be one, make things convenient for the importing of conduit, improve the success rate of intubate, a damage to giving birth to when having alleviated intubate; Most advanced and sophisticated pliability and deformability have also been improved conduit and have been entered the difficulty of further inserting behind the glottis, have reduced the damage of intubate to throat, glottis harmony student trachea antetheca mucosa.

The specific embodiment
Guiding type endotracheal tube, mainly comprise conduit 1 and ventilating joint 2, it is characterized in that conduit 1 tip is provided with an arc-shaped curved surface 3, the circular arc of receiving in arc-shaped curved surface 3 integral body are, most advanced and sophisticated 4 are the outside of belly is upturned, ends at the body position of center line, the most advanced and sophisticated both sides of conduit 1 are provided with a pair of circular down Mo Fei hole 5 of point of presenting, and conduit 1 is 90 ° of arc-shaped bends at most advanced and sophisticated 1/3 place;
When being expert at tracheal intubation, when arc-shaped curved surface 3 enters glottis, reason owing to the human physiological structure, conduit 1 is extruded, alters course, and making conduit enter the air flue degree of difficulty increases, and this moment is because the compressing of physiological structure, last point changes the finedraw shape into by original opening shape in circular Mo Fei hole 5 down, thereby cushioned the compressing that physiological structure brings, avoided the damage of mucosa, the difficulty that makes conduit 1 insert reduces.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection of the present utility model.
