BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary device applied to a doll for intubation training in order to carry out insertion training of a laryngeal mask used for airway maintenance in anesthesia, intensive care, and emergency medicine. .

[0002]

2. Description of the Related Art As a method for securing an oral airway in anesthesia or the like, a method of endotracheal intubation is generally used, and a method of inserting a laryngeal mask into the larynx has recently been performed. For this reason, there was no training device for the insertion of the laryngeal mask, and the patient experienced the case to acquire and master the skill of inserting the laryngeal mask.

[0003]

As described above, if the skill of inserting a laryngeal mask is to be acquired and familiarized based on the experience of the case as described above, it will take time to acquire and acquire the insertion skill because the opportunity for insertion is restricted. In addition, in order to maintain the acquired skills, it is necessary to insert them at intervals, but there is no such opportunity. Further, in the case of a paramedic or the like involved in emergency medical care, it is necessary to insert the laryngeal mask promptly and accurately under difficult emergency conditions, and there is a limit to mastering the skill through cases. Therefore, it is necessary to provide many opportunities for inserting the laryngeal mask, and it is desirable to perform insertion training for the laryngeal mask in a widely used intubation training doll. By the way, the laryngeal mask is that the tip of the mask is slanted from the right corner of the mouth to the hard palate, and the whole mask is spread with the hard palate, and the tip of the mask is pushed along the curve of the pharyngeal rear wall so that the tip of the mask faces the larynx. Inserted in. However, the doll for intubation training has low rigidity because the posterior pharyngeal wall is molded with a flexible material that is integral with the flexible tube that forms the esophagus, so that the posterior pharyngeal wall is pushed by the laryngeal mask when the laryngeal mask is inserted. The back of the laryngeal mask bulges out and the tip of the laryngeal mask is pushed in the wrong direction, so that the laryngeal mask cannot be inserted into the larynx. In view of the above points, an object of the present invention is to provide an auxiliary device for allowing insertion of a laryngeal mask by a doll for intubation training.

[0004]

In order to achieve the above-mentioned object, the present invention is a laryngeal mask insertion training auxiliary device applied to a bust-shaped doll for intubation training, which is inserted into the head of the doll. The doll's esophagus is detachably engaged with a spatula-shaped instrument body having a required rigidity, which comes into contact with a portion extending from the posterior pharyngeal wall of the doll to the upper part of the esophagus.

[0005]

The auxiliary device is brought into contact with the portion of the doll for intubation training that extends from the posterior pharyngeal wall to the upper esophagus to ensure the required rigidity of the portion from the posterior pharyngeal wall to the upper esophagus. This prevents bulging of the posterior pharyngeal wall due to the insertion force of the laryngeal mask, and the laryngeal mask can be indirectly guided by an auxiliary device along the posterior pharyngeal wall and inserted into the larynx. Further, if the auxiliary device is removed from the doll, the original intubation training can be performed.

EXAMPLES Referring to FIG. 1, reference numeral 1 shows a laryngeal mask used for airway maintenance in anesthesia, intensive care, and emergency care. The laryngeal mask 1 is formed by attaching a hollow cuff 3 to the periphery of an oval-shaped mask body 2, and a breathing tube 4 is attached to a tube connecting portion 4a on the back surface of the mask 1 communicating with a breathing hole 2a formed in the mask body 2. Cuff 3 with connecting
The air tube 5 for air injection is connected to the cuff 3
The inside of the cuff 3 is squeezed and the cuff 3 is squeezed into the patient's larynx. Then, air is injected into the cuff 3 to inflate the cuff 3, and the mask 1 is used as shown in FIG. 1 (b). Cover the patient's larynx to secure the airway.

In order to acquire and master the skill of inserting the laryngeal mask 1, a doll 10 for intubation training fixed in a supine position on a fixed base 6 as shown in FIG. 2 (b) is shown in FIG. 2 (a). The auxiliary device 20 shown in the figure was attached to the doll 10 so that the laryngeal mask 1 could be inserted and trained. The intubation training doll 10
It has a bust-like shape composed of a chest 11 and a head 12, and is fixed to a fixing base 6 at the chest 11. The chest 11 is made of plastic or the like in a hollow shape, and the head 12 is fixed to the periphery of the opening formed in the center of the shoulder. Head 12
A skin 13 formed in the same shape as a human head and made of a flexible material such as rubber, a jaw portion 14 formed of a hard material such as plastic and an upper jaw 14a and a lower jaw 14b, and the jaw portion 14 are encapsulated. A bag-shaped oral member 15 formed of a flexible material such as rubber, and an esophagus 16 integrally formed with the oral member 15
And a trachea 17 extending from the esophagus 16 in the larynx, the open end of the oral member 15 is adhered to the inner surface of the peripheral portion of the mouth hole 13a formed in the epidermis 13, and the pharynx of the oral member 15 is further provided. The nasal cavity member 18 was attached to the upper portion, and the open end of the nasal cavity member 18 was adhered to the inner surface of the peripheral portion of the nostril 13b formed in the epidermis 13.

The auxiliary device 20 is a spatula-shaped device made of a relatively rigid material such as plastic, which comes into contact with a portion of the oral member 15 of the doll 10 extending from the posterior pharyngeal wall 15a to the upper part of the esophagus 16. The main body 21 is formed with an engaging portion 22 that engages with the esophagus 16 so that the esophagus 16 is sandwiched between the auxiliary body 20 and the back of the esophagus 16 from the abdominal opening of the chest 11 of the doll 10. When the insertion portion 22 is inserted into the doll 10, the engaging portion 22 is engaged with the esophagus 16, and when the distal end of the engaging portion 22 abuts against the larynx widening portion of the esophagus 16 and further insertion is stopped, the instrument body 21 Is the posterior wall of the pharynx 1
The portion extending from 5a to the upper part of the esophagus was contacted.
The instrument body 21 may be anything that comes into contact with the posterior pharyngeal wall 15a and the upper part of the esophagus 16 at a portion corresponding to the range of cervical vertebrae 1 to 3 in the human body. Further, the instrument body 21 is formed to have a curve substantially similar to the curve extending from the posterior pharyngeal wall 15a to the upper part of the esophagus with a pillow placed on the occipital region of the human body in the supine position, and the rigidity that resists the insertion force of the laryngeal mask. Further, a stopper portion 23 bent to the back side is formed at the tail end portion of the device body 21, and a ring-shaped finger hook portion 24 is formed so that the auxiliary device 20 can be easily attached and detached.

Next, the usage state of the auxiliary device 20 will be described based on the insertion of the laryngeal mask 1 into the intubation training doll 10. First, as shown in FIG. 3 (a), with the air inside the cuff 3 of the laryngeal mask 1 being squeezed to squeeze the cuff 3, the laryngeal mask 1 is slanted from the right mouth corner of the doll 10 to the upper jaw 14a. Then, the entire back face of the mask 1 is slid along the upper jaw 14a while the trajectory of the mask 1 is adjusted so that the tip of the mask 1 faces the larynx by spreading the entire mask 1 on the upper jaw 14a. Push it so that it touches. Mask 1 so far
Can be inserted without the auxiliary device 20 because the upper jaw 14a of the doll 10 is formed of a hard material and has a required rigidity. Next, the mask 1 is inserted into the pharynx along the posterior pharyngeal wall 15a. At this time, if the doll 10 is not equipped with an auxiliary device, the rear wall of the pharynx 15a is formed of rubber or the like as described above and has low rigidity, so that it bulges rearward due to the insertion force of the mask 1. With that momentum, the mask 1 as shown in FIG.
4 is bent toward the back side of the mask main body 2 and does not proceed, or the mask main body 2 is curved to the front side due to the restoring force of the posterior pharyngeal wall associated with the swelling as shown in FIG. Is not inserted into the trachea 17, and the mask 1 cannot be correctly inserted into the larynx. However, as shown in FIG. 3B, when the auxiliary device 20 is in contact with the part of the doll 10 extending from the posterior pharyngeal wall 15a to the upper part of the esophagus 16, the mask 1
Swelling of the posterior pharyngeal wall 15a to the back case due to the insertion force of the mask is prevented, and the mask 1 can be indirectly guided by the auxiliary device 20 and inserted into the larynx. After that, as shown in FIG. 3C, air is injected into the cuff 3 of the mask 1 from the air tube 5 to inflate the cuff 3, and the mask 1 covers the larynx to secure the airway.
