As described above, the insertion of an airway intubation to secure the airway of an unconscious patient is currently only at the level where only a few experts in advanced medical institutions can skillfully handle it, and even in this case, it is difficult to perform the procedure because a laryngoscope must be used. follows

In addition, when the patient is conscious, he resists during the laryngoscope or tracheal intubation procedure, which causes physical damage to the patient and makes laryngoscope and tracheal intubation difficult. There is an inconvenience.

In addition, if the larynx is inflamed or swollen due to trauma, etc., it is impossible to visually confirm the insertion of the tracheal intubation into the airway using a laryngoscope, making it practically impossible to intubate the trachea, which also makes the procedure difficult. there is.

There are various reasons, but even if the intubation procedure is performed, it is difficult to confirm if the distal end of the intubation enters the esophagus rather than the airway. It is late to recognize that intubation has been performed abnormally.

In this way, when the airway intubation is connected to the esophagus rather than the airway, normal oxygen supply to the airway cannot be smoothly performed, and when intubation is performed later through the airway rather than the esophagus, time is delayed, which endangers the patient's life. It is a situation that is not free from various problems such as being a cause.

Accordingly, the present invention was invented to solve the above problems, and the outer cannula 110 inserted through the oral cavity 101 to the vicinity of the airway 102;

The airway intubation unit 100 to which the technique of the present invention is applied includes an outer cannula 110 inserted through the oral cavity 101 to the vicinity of the airway 102, and an airway 102 through the outer cannula 110. It consists of an inner cannula 130 that is located inside the inlet and substantially supplies oxygen.

The outer cannula 110 has a tube-type outer cannula body 111 having a curvature equivalent to that of the oral cavity 101 and the esophagus 103 and having an arc shape, and the outer cannula The body 111 is made of a hard material such as silicone, plastic, or PVC that can maintain its shape even if there is movement after insertion into the patient.

On the outside of the outer cannula body 111, a flow prevention device 112 for holding the outer cannula 110 in close contact with the mouth of the patient is further provided, and on the inside of the outer cannula body 111, an inner It includes guide means 113 for guiding the cannula 130 into the airway.

The flow prevention device 112 is integrally or independently formed at the outer end of the outer cannula body 111 and coupled to the outer cannula body 111, while the inner cannula 130 passes through the center. It is provided with an anti-gut body 115 having an inner cannula hole 114 so as to be able to

Fixed blades 116 are integrally formed on both sides of the anti-ball body 115, and fixing holes 117 are formed at both ends of the fixed blades 116 to connect fixing means 118 such as bands. So that it can be maintained by banding with the patient's head.

The induction means 113 forms an induction area 120 in the form of half open in the direction of the airway at the inner end of the outer cannula body 111, and the outer cannula in the middle of the induction area 120. The body 111 is formed with an guide jaw 121 protruding in the direction of the airway for guiding the inner end of the inner cannula 130 entering the airway 102.

Although the degree of opening of the induction area 120 is described as about half of that of the outer cannula body 111, the degree of opening can be determined in various ways from 1/3 to 2/3 of the diameter of the outer cannula body 111. will be.

The guide jaw 121 forms an inclined surface 123 protruding from the entry direction to the airway direction so as to facilitate the entry of the inner cannula 130 and guide it in the direction of the airway 102.

The iter cannula body 111 of the induction area 120 includes a balloon 125 and is connected to the pump 126 located outside the outer cannula 110, and is inflated by pumping so that the induction area 120 It allows the entire body to be pushed in the direction of the airways.

The balloon 125 may be configured to surround the entire induction area 120, or when the balloon 125 is inflated by mounting the balloon 125 only in the opposite direction of the airway 102, the induction area 120 is moved to the airway ( 102), it would be more desirable to be able to easily push in the direction.

The inner cannula 130 is made of the same material as the outer cannula 110, such as silicone, plastic or PVC, and the outer cannula 110 has good movement (insertion and release) inside the outer cannula 110. It has more softness and has a tubular type inner cannula body 131 having a relatively longer length than the outer cannula 110.

The upper end of the inner cannula body 131 has a connector 132 for connecting to an oxygen supplier, and the inner cannula 130 is properly inserted into the airway 102 at the lower end of the inner cannula body 131. To include an identification means 135 that the operator can identify whether or not it has been.

The identification means 135 includes a fluorescent or phosphorescent material at the lower end of the inner cannula body 131 or from the outside through an energizing means such as a conductive wire connected along the wall surface of the inner cannula body 131. It may include an ultra-thin lamp that is turned on by receiving power from a battery or the like.

When the identification means 135 is normally inserted into the airway 102, it can be identified by looking at the light emission state from the outside, but when inserted into the esophagus, it cannot be visually recognized from the outside even if it emits light, so it is difficult to identify the normal insertion state. will be able to

Looking at the state of use of the airway intubation unit 100 to which the technology of the present invention is applied as described above is as follows.

Initially, the outer cannula 110 constituting the airway intubation unit 100 is inserted through the oral cavity of the patient so that the fixed wings 116 of the flow prevention device 112 are in close contact with both sides of the mouth, and then the fixing hole 117 ) to prevent the outer cannula 110 from moving randomly by binding it to the head using a fixing means 118 such as a band.

At this time, the inner end of the outer cannula 110 reaches a position close to the airway 102 and the esophagus 103, and the guide area constituting the guide means 113 formed in the direction of the airway 102 at the inner end ( 120) is directed in the direction of the airway 102.

In this state, the air balloon 125 constituting the induction means 113 and coupled to the induction area 120 is inflated using the pump 126 so that the induction area 120 is positioned closer to the airway 102. will do

As described above, the inner cannula body 131 constituting the inner cannula 130 is inserted into the outer cannula body 111 while the outer cannula body 111 is positioned close to the airway 102. .

Then, the inner cannula 130, which is softer than the outer cannula 110, is naturally inserted, and in particular, the inner cannula 130 is also inserted along the outer cannula 110 facing the airway 102. ) direction is inserted.

In this process, the inner end of the inner cannula body 131 can be naturally inserted in the direction of the airway 102 by the guide jaw 121 and the inclined surface 123 further formed in the guide area 120.

That is, when the inner end of the inner cannula body 131 reaches the guide area 120 of the outer cannula body 111, it changes direction toward the airway 102 along the guide jaw 121 and the inclined surface 123. because it becomes possible.

In addition, the inner end of the inner cannula body 131 is naturally inserted into the airway 102 by the induction means 112, but it can be confirmed that it is correctly inserted is an identification means ( 135), so it can be confirmed from the outside through the neck (airway) by light emission (phosphorescence) of the identification means.

When the inner cannula body 130 is inserted into the airway 102, it can be confirmed through the airway from the outside by the identification means 135, but when it is inserted into the esophagus 103, the identification means 135 emits light. Even if it is, it is difficult to identify the light emitting state from the outside, so it is possible to determine whether it is inserted into the airway 102.

In the description of the present invention, it is exemplified that the intubation unit 100 is inserted into the oral cavity to perform the procedure, but it is natural that the intubation unit 100 can be inserted into the nasal cavity and the procedure is not specified as either the oral cavity or the nasal cavity.

As described above, the present invention can accurately and naturally insert the inner cannula into the airway by the outer cannula naturally inserted in the oral cavity and esophageal direction and the guide means of the outer cannula, so that even without a high level of expertise or experience, the airway can be secured. Since oxygen can be supplied to the patient through the sound level, it has advantages such as providing ease of operation and ensuring safety.
