Abstract
Description
本発明は，体外式気道確保器具に関する。さらに詳しくは，術中患者の舌根沈下を防止することを目的とした体外式気道確保器具に関する。 The present invention relates to an external airway securing device. More particularly, the present invention relates to an extracorporeal airway securing device for the purpose of preventing tongue subsidence in patients during surgery.
手術を行う際，患者が入眠すると，舌根沈下が生じ，気道を閉塞することがしばしば生じる。この舌根沈下による気道閉塞は，患者の呼吸困難ないし低酸素状態を生じさせてしまうため，対処が必須である。 When performing surgery, if the patient falls asleep, tongue base subsidence often occurs and obstructs the airways. Airway obstruction due to tongue subsidence can cause dyspnea or hypoxia in the patient and must be addressed.
舌根沈下の対処法として，例えば，エアウェイと呼ばれる器具を挿入し気道を確保したり，患者の体位を変更したり，時には麻酔科医自身が患者の顎を上げた状態を保持して舌根沈下を防ぐ場合がある。 As countermeasures for tongue subsidence, for example, an instrument called an airway is inserted to secure the airway, the patient's position is changed, and sometimes the anesthesiologist himself keeps the patient's chin raised to prevent subsidence. May prevent.
エアウェイは，口腔内に器具を挿入するため侵襲的である。そのため，エアウェイの咽頭への刺激により，唾液を誤嚥して呼吸状態が悪化したり，咳嗽反射を誘発して体動により手術の妨げとなることがあり，時には手術を中断せざるを得ない状況に陥ることがある。さらに，麻酔科医による顎の保持については有効な対処法ではあるものの，麻酔科医自身の麻酔業務等に支障が生じることから，適切な対処法とは言い難い。 Airways are invasive because they insert instruments into the oral cavity. Therefore, stimulation of the pharynx of the airway may cause aspiration of saliva and worsen the respiratory condition, or may induce cough reflex and obstruct the operation due to body movements, and sometimes the operation must be interrupted You may fall into a situation. Furthermore, although holding the jaw by an anesthesiologist is an effective countermeasure, it is difficult to say that it is an appropriate countermeasure because it will interfere with the anesthesiologist's own anesthesia work.
このように，舌根沈下を防ぐ種々の手段があるものの，確立された手法はないといえる。このような事情の中，舌根沈下を防ぐための非侵襲的な技術が開示されている（特許文献１）。

＜体外式気道確保器具の態様例２＞
体外式気道確保器具の別の例を図１０ないし図１１を用いて説明を行う。この態様の体外式気道確保器具では，顎先挙上部材が上顎骨固定部材として，ラチェット式ベルト２７と固定ゴム２８から構成されている。加えて，下顎固定部材は，下顎両側の下顎角を固定する下顎角固定部材１２から構成されている。このような構成を備えることにより，鼻下を軸として，安定かつ調整しやすい顎先挙上が可能となるとともに，首から下の体位変更にも対応しうることから，体外式気道確保器具の利便性を向上させる効果を有する。
<Example 2 of an external airway securing device>
Another example of the extracorporeal airway securing device will be described with reference to FIGS. In the extracorporeal airway securing device of this embodiment, the chin tip raising member is composed of a ratchet belt 27 and a fixing rubber 28 as a maxillary bone fixing member. In addition, the lower jaw fixing member is composed of a lower jaw angle fixing member 12 that fixes lower jaw angles on both sides of the lower jaw. By having such a configuration, it is possible to raise the chin tip that is stable and easy to adjust with the nose as the axis, and it is possible to cope with changes in the body position from the neck down. It has the effect of improving convenience.
上顎骨固定部材は，上顎骨に設置・固定されるとともに下顎固定部材に連結し，鼻下を軸として下顎固定部材を引き上げ，顎をあげる役割を有する。上顎骨固定部材は，この役割を果たす限り特に限定する必要はなく，種々の構成・態様をとることができる。 The maxillary bone fixing member is installed and fixed to the maxilla and is connected to the mandibular fixing member, and has a role of raising the jaw by lifting the mandibular fixing member around the nose as an axis. The maxillary fixation member is not particularly limited as long as it fulfills this role, and can have various configurations and modes.
図１０ないし図１１におけるラチェット式ベルト２７は，下顎角固定部材１２とラチェット式に連結している。この連結度合いを調整することにより，下顎角固定部材１２を引き上げることが可能となり，結果として下顎をあげることができる。また，ラチェット式ベルト２７は固定ゴム２８につながっており，患者の呼吸を窮屈にすることがないよう，首の後ろを通じて固定されている。 The ratchet belt 27 in FIGS. 10 to 11 is connected to the lower jaw angle fixing member 12 in a ratchet manner. By adjusting the degree of connection, the lower jaw angle fixing member 12 can be pulled up, and as a result, the lower jaw can be raised. The ratchet belt 27 is connected to a fixed rubber 28 and is fixed through the back of the neck so as not to make the patient's breathing cramped.
上顎固定部材として，ベルト様の形状を有する部材を用いることが好ましい。これにより，下顎固定部材との連結度合いをベルトの長さとして調節することにより，下顎の挙げ具合を調整することが可能となることから，体外式気道確保器具の利便性を向上させる効果を有する。
ベルト様部材と下顎固定部材の連結様式については，ラチェット式に限らず，例えば，ズボン用ベルトのように，ベルト様部材に複数の穴をあけ，下顎固定部材にこれに対応する金属部材を設置するような構成（この構成を「ベルト式」する）としたり，ヘッドホンのようにスライドさせて調整するような構成（この構成を「スライド式」とする）とするなどできる。
A member having a belt-like shape is preferably used as the upper jaw fixing member. By adjusting the degree of connection with the lower jaw fixing member as the length of the belt, it becomes possible to adjust the degree of lifting of the lower jaw, thus improving the convenience of the external airway securing device. .
The connection style of the belt-like member and the lower jaw fixing member is not limited to the ratchet type. For example, a plurality of holes are made in the belt-like member such as a trouser belt, and a corresponding metal member is installed in the lower jaw fixing member. Such a configuration (this configuration is “belt type”), or a configuration that is adjusted by sliding like a headphone (this configuration is “slide type”).
上顎固定部材として，ヘッドホンのヘッドバンドのような形状（ヘッドバンド様形状）からなり，弾性力を有する部材のものを用いることが好ましい。これにより，両側の下顎角を内側に圧迫することが可能となり，両側の下顎固定部材の固定性・安定性を増加させる効果を有する。
この場合，鼻の下を支点として，両側の下顎角固定部材との間のヘッドバンドの長さを調整することにより，下顎角固定部材を上顎側へ挙上することが可能となる。この調整様式としては，前述の種々の連結様式を採用することができる。
As the upper jaw fixing member, it is preferable to use a member having a shape (headband-like shape) like a headband of a headphone and having an elastic force. This makes it possible to press the mandibular angle on both sides inward, and has the effect of increasing the fixation and stability of the mandibular fixation members on both sides.
