Description

  TECHNICAL FIELD The present invention relates to a tracheal intubation aid used when performing oral tracheal intubation and a method of using the same.

  In anesthesia or emergency medical care, the airway is secured by inserting or placing an endotracheal tube into the trachea (human airway). Conventionally, when performing endotracheal intubation by inserting an endotracheal tube into a patient's trachea, as shown in FIG. 3, the patient's oral cavity 101 is pushed open with a laryngoscope 102 and the endotracheal tube 103 is viewed while looking at the back of the throat. Was inserted. In recent years, there is a stylet (video stylet scope) with a video camera, and an endotracheal tube can be directly attached to the stylet for intubation. In this case, a laryngoscope is unnecessary.

  Specifically, in the case of a video styletscope, the doctor opens the mouth of the patient performing tracheal intubation and inserts a stylet with a video camera to look for the epiglottis. When the epiglottis is confirmed, the endotracheal tube is inserted into the glottis. When the tip of the endotracheal tube enters the glottis, the endotracheal tube is advanced to an appropriate position while firmly grasping the position of the stylet. Then, with the endotracheal tube firmly held, the stylet is removed.

  By the way, when the endotracheal tube is intubated using a stylet with a video camera, the epiglottis is in contact with the posterior pharyngeal wall and the glottis cannot be visually recognized, so that intubation may be difficult. That is, the airway that passes from the oral cavity (or nasal cavity) to the pharynx and the larynx including the vocal cords crosses the esophagus, so that food and drink do not enter the airway, the pharynx is raised and swallowed during swallowing Has closed the vocal cords.

  Airway closure may occur due to tongue base subsidence, foreign matter, edema, etc. When tracheal intubation, the epiglottis that causes airway closure must be raised.

  However, the conventional blade is provided for the purpose of assisting the insertion and placement of the endotracheal tube, and has no configuration or purpose for raising the epiglottis.

  In addition, when using an auxiliary blade, when performing tracheal intubation, one doctor operates the video camera with one hand and advances and holds the blade with the other hand to advance the endotracheal tube. To complete the intubation, you have to leave it to another person's assistant. That is, when one doctor cannot complete tracheal intubation and it is necessary to perform fistula of the epiglottis as well, there is no choice but to rely on multiple hands.

  Therefore, the present invention, when performing oral tracheal intubation, by attaching to the endotracheal tube itself, the fistula of the epiglottis in contact with the pharyngeal posterior wall can be easily and safely performed, and the endotracheal tube is connected to the glottis. An auxiliary tool for tracheal intubation that can be easily removed when inserted into a tube and a method of using the same.

  In order to solve the above problems, the present invention provides the following.

  (1) An auxiliary tool for tracheal intubation, which has a substantially semicircular arc shape, has crests formed at both ends, and troughs formed from one end to the other end.

  According to the present invention, on both sides, a crest is integrally formed at one end and the other end, and a trough is integrally formed from one end to the other, and the endotracheal tube attached by both the crests is gripped. Thus, the tracheal intubation aid equipped with the endotracheal tube can be inserted into the airway. At this time, the fistula of the epiglottis in contact with the posterior pharyngeal wall can be performed at one end or the other end.

  In addition, since the valley is formed from one end to the other end without forming a straight line from one end to the other end, the contact area with the attached endotracheal tube is reduced, and the removal tool for tracheal intubation is removed. Can be made easier. On the other hand, in order to prevent unintentional removal of the auxiliary tool for tracheal intubation, the peaks at both ends function as hooks for holding the endotracheal tube. Further, by integrally forming the crests at both ends and the troughs connected to the crests, it is possible to eliminate the risk of parts falling off.

  (2) Among the ridges forming the peak, the ridges at one end are spaced apart in the circumferential direction, and the ridges at the other end are close to each other in the circumferential direction. .

  According to the present invention, since the protruding ridges at one end are spaced apart in the circumferential direction, the attached endotracheal tube can be easily removed as compared with the protruding ridges at the other end. . Moreover, since the convex line | wire of the other end is adjoining in the circumferential direction, natural removal of the mounted endotracheal tube can be made difficult compared with the convex line | wire of the one end spaced apart. By such separation and proximity of the ridges, it is easy to remove the tracheal intubation aid when inserting the endotracheal tube into the glottis and firmly prevent unintentional removal of the tracheal intubation aid Can do.

  (3) A tracheal intubation assisting device characterized in that at least the one end and the vicinity thereof are smooth.

  According to the present invention, since at least one end and the vicinity thereof are smooth, damage to the pharynx and the pharynx can be reduced, and the endotracheal intubation aid can be inserted into the oral cavity and the airway from one end.

  (4) The usage method which attaches an endotracheal tube to a half-shaped hollow cylindrical part using the said auxiliary tool for tracheal intubation.

  According to the present invention, by attaching the endotracheal tube to the tracheal intubation aid, the fistula of the epiglottis in contact with the pharyngeal posterior wall can be easily performed.

  The tracheal intubation aid of the present invention and the method of using the same have the effect of facilitating the fistula of the epiglottis by attaching the tracheal intubation aid to the endotracheal tube itself. In addition, the pharynx and pharyngeal damage during insertion can be reduced, and the endotracheal tube can be easily removed when inserted into the glottis.

The figure which shows the auxiliary tool for tracheal intubation which concerns on embodiment of this invention. The figure which shows the use condition of the auxiliary tool for tracheal intubation which concerns on embodiment of this invention. The figure which shows the method of the conventional tracheal intubation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing a tracheal intubation auxiliary tool 1 according to an embodiment of the present invention, in which (A) is a side view, (B) is a rear view, and (C) is a front view. The tracheal intubation auxiliary tool 1 has a substantially semicircular arcuate shape in which a hollow cylindrical pipe member is halved, and includes a first peak F ₁ and a second peak F ₂ and F ₁ -F. ₂ are formed integrally. Since it is a hollow cylindrical pipe member, both ends 2 and 3 are opened, and an endotracheal tube is attached to the open ends 2 and 3. In addition, the pipe member of the tracheal intubation auxiliary tool 1 is made of a flexible flexible material such as polyethylene and is formed so as not to have a sharp shape.

The first peak portion F1 is composed of a _first ridge 4a and a second ridge 4b located on the coaxial circumference, and the tip of the first ridge 4a and the tip of the second ridge 4b are circumferential. And has a function of mounting an endotracheal tube as a deep first mounting hook. Since the circumference is longer than that of the second hook for attachment described later, the endotracheal tube attached by artificial external pressure can be removed by the proximity in the circumferential direction, but unintended natural It makes removal difficult.

The second crest F ₂ is composed of third projections 5a and fourth projections 5b coaxially positioned circumferentially, the tip and the tip of the fourth projections 5b of the third projections 5a are circumferentially It has a mounting function of the endotracheal tube as a shallow second mounting hook. Since the circumference is shorter than that of the first attachment hook, the removal of the attached endotracheal tube can be facilitated by the distance in the circumferential direction. That is, since the second peak F ₂ is located in the patient's body (the epiglottis), it is difficult to directly apply artificial external pressure, and contact with the endotracheal tube so that it can be easily removed by a simple operation. The area is reduced.

Further, in order to reduce damage of the pharynx and pharynx during insertion of the auxiliary instrument 1 for tracheal intubation, and to facilitate fisting of the epiglottis in contact with the pharyngeal posterior wall, the second peak F ₂ and its The vicinity is smooth and the open end 3 has a thin spatula shape.

Valleys T is first mountain portion F ₁ and the second continuous with the mountain portion F _2, having the reproduction function of the endotracheal tube. Spaced valleys T against the circumferential direction, the first crest F ₁ and greater than the second crest F _2, the circumference than the first mounting hooks and second mounting hooks short It has become.

  FIG. 2 is a diagram showing a usage state of the tracheal intubation aid 1 according to the embodiment of the present invention. The tracheal intubation auxiliary tool 1 is directly attached to the endotracheal tube 20 and can easily perform fist raising of the epiglottis before tracheal intubation. In addition, since the video stylet scope 10 is inserted into the endotracheal tube 20 from the distal end 11 thereof, the endotracheal tube 20 into which the video stylet scope 10 is inserted is attached to the endotracheal intubation aid 1. Preparation for tracheal intubation can be made and can be adequately handled by one doctor.

Removal of the removed tracheal intubation auxiliary tool 1 from the endotracheal tube 20 is performed by removing the first mounting hook at the open end 2 (first peak F ₁ ) located outside the body, and removing the tracheal intubation auxiliary tool 1. By pulling out, the second mounting hook at the open end 3 (second peak portion F ₂ ) located in the body is released and can be removed.

  INDUSTRIAL APPLICABILITY The endotracheal intubation aid and the method of using the same according to the present invention are useful as those that can easily perform fistula of the epiglottis during tracheal intubation with a simple operation.
