The flange 140 protrudes like a pair of wings around the intubation body part 100 , and has a larger area than the cross-section of the intubation body part 100 .
본 발명의 추가 실시예에 따르면, 상기 플랜지(140)의 일면은 중심부를 기준으로 후방(후두 방향)을 향하도록 일정곡률로 만곡되게 형성될 수 있다.According to a further embodiment of the present invention, one surface of the flange 140 may be formed to be curved with a certain curvature toward the rear (occipital direction) with respect to the center.
다시 말해, 상기 플랜지(140)의 일면은 중심부를 기준으로 환자의 입술 주변과 맞닿는 면이 일정곡률로 만곡되게 형성될 수 있다.In other words, one surface of the flange 140 may be formed so that a surface in contact with the periphery of the patient's lips with respect to the center is curved with a predetermined curvature.
상기 플랜지(140)가 후방을 향하도록 만곡되게 형성될 때의 작용효과를 살펴보면, 상기 플랜지(140)에 개구되어 형성된 상기 결합홈(120)에서 기관삽관튜브(T)에 가해지는 힘의 방향이 본 발명의 기도유지 및 기관삽관튜브 고정장치로 향하게 됨으로써, 상기 기관삽관튜브(T)를 보다 안정적으로 고정할 수 있게 된다.Looking at the effect when the flange 140 is formed to be curved toward the rear, the direction of the force applied to the tracheal intubation tube (T) in the coupling groove 120 formed by opening the flange 140 is By heading to the airway maintenance and tracheal intubation tube fixing device of the present invention, it is possible to more stably fix the tracheal intubation tube (T).
또한, 본 발명의 다른 추가 실시예에 따르면, 상기 삽관몸체부(100)의 후단부에는 환자의 기도 방향으로 기관삽관튜브(T)의 삽입이 원활해지도록, 상기 삽관몸체부(100)의 폭과 대응되는 폭을 갖고 단부가 라운드진 형상으로 이루어진 삽관가이드(160)가 상기 삽관몸체부(100)의 말단에 일체로 형성될 수 있다.In addition, according to another additional embodiment of the present invention, the rear end of the intubation body part 100 has a width of the intubation body part 100 to facilitate the insertion of the tracheal intubation tube (T) in the patient's airway direction. An intubation guide 160 having a width corresponding to that and having a rounded end may be integrally formed at the distal end of the intubation body 100 .
상기 삽관가이드(160)에 의하면, 환자의 충분한 기도 확보는 물론이고, 기관삽관튜브(T)의 삽입을 보다 원활하게 행할 수 있는 이점을 나타낸다.According to the intubation guide 160, the patient's sufficient airway is secured, as well as the advantage of more smoothly inserting the tracheal intubation tube (T).
상기에서 설명한 삽관몸체부(100)는 탄성의 폴리스티렌(PS, polystyrene), 폴리에틸렌(PE, polyethylene), 폴리프로필렌(PP, polypropylene), ABS 수지(ABS resin, acrylonitrile-butadiene-styrene resin), 폴리염화비닐(PVC, polyvinyl chloride) 중에서 선택된 어느 하나의 소재 또는 2가지 이상이 혼합된 소재로 이루어질 수 있다.The intubation body 100 described above is elastic polystyrene (PS, polystyrene), polyethylene (PE, polyethylene), polypropylene (PP, polypropylene), ABS resin (ABS resin, acrylonitrile-butadiene-styrene resin), polychloride It may be made of any one material selected from vinyl (PVC, polyvinyl chloride) or a mixture of two or more materials.
