氣管內管置入為建立暢通呼吸道與治療呼吸衰竭的重要工作，亦為重症與麻醉醫療中重要的處理之一。尤其，新生兒的呼吸道狹小且解剖結構和成人差異極大，其通常伴隨上呼吸道阻塞與大量氣管分泌物，氣管內管置入治療為臨床上最難處理的病患族群。
為解決此特定族群的臨床症狀，本研究開發一針對急重症兒童、新生兒或早產兒的氣管插管導引或更換的導引系統，降低病兒因氣管插管或更換可能造成的併發症，本實驗開發之導引系統轉向結構將可如同導引通條般容易操作，亦可快速地進行呼吸道處理，降低呼吸道意外傷害等醫源性的併發症發生。此導引系統利用紡錘型氣囊轉向設計轉向，分別是四環式轉向模型與二環式轉向模型，依據啟動氣囊層數控制導引系統轉向程度。轉向設計由多層交錯之氣囊所構成，藉由增加多數量的氣囊層可提高轉向之解析度，初估可達到90˚及180˚之轉向角度，不僅可達到某程度的轉向，亦可利用啟動不同排之氣囊(即軸向相通之氣囊)達到各方位之轉向，完成可控制轉向及方位的導引系統。

Endotracheal intubation is an indispensable technique for the establishment of secured airway and the treatment of respiratory failure. It is one of the most significant sequences in critical care and anesthesiology. Airway management for neonate and pediatric patient is more challenging than adult, because of the different anatomical feature, the smaller airway diameter and accompanied by upper airway obstruction and more secretions.
To resolve the clinical symptoms, the study developed a guiding system that can be carried and redirected for tracheal intubation in acute and severe children, newborns, or premature babies to reduce complications from their endotracheal intubation or replacement. This guiding system with our special steering design will be easy to operate as exchange catheters. It can also quickly perform respiratory treatment and reduce the occurrence of iatrogenic complications as respiratory accidental injuries. The developed guiding system utilizes a spindle-type air bags steering system. There are two models, four-ring steering model and two-ring steering model. The steering degree is controlled according to the number of activated layers. In addition, its steering system consists of a multi-layered air bags. The steering design consists of a multi-layered and staggered airbag. The steering resolution can be improved by adding a large number of airbag layers. Preliminary assessment of the steering angle can reach 90˚ and 180˚.Not only a certain steering degree could be achieved, but also the steering of all sides by switching on different rows of air bags can complete the guiding system that controls steering and orientation.
