The development of a novel steerable bougie to assist in airway management
Background: This paper describes the development of a new airway device that will improve the speed and safety of endotracheal intubation in anaesthesia and critical care. Case of need, design specification and fabrication of the steerable bougie mechanism is discussed. Aims: Identify the need for a novel steerable bougie whilst considering technology readiness levels associated with medical device design. Analyse and produce suitable mechanisms utilising smart materials to increase device functionality aiding successful patient intubation procedures. Methods: This work describes the total design activity that contributes to the successful development of medical devices, from case of need, to smart material actuation mechanisms. Research focuses on identifying a suitable control mechanism to allow a steerable tip to be integrated into a bougie with a control device attached to the laryngoscope. Results: Data collected from a user group survey supported the development of a novel bougie, with better shape retention, variable rigidity within the tip, and an integrated steerable function. Analysis of several mechanisms, artificial muscles, and smart materials identified a cost-effective steerable mechanism that can be incorporated into a bougie. Conclusion: Users have defined a need for an improved bougie. Controlling smart materials and mechanisms, within the predefined dimensions, identified strengths and weaknesses associated with steerable functions. The performance of the selected mechanism for incorporation requires a high level of control to accurately steer a device within the human airway

Utilising object tracking for the performance analysis of difficult airway equipment - a Shape Retention Testing System (SRTS)
Failure to secure the airway on induction of anaesthesia can result in death and disability. Current equipment does not always provide an optimum solution. Most anaesthetists consider bougies essential equipment for safe anaesthesia. Evaluative systems providing accurate objective data assessing bougie introducer performance data do not exist. The Shape Retention Testing System (SRTS) utilises the IntelÂź RealSenseTM SR300 camera to create an accurate and repeatable testing environment. SRTS collected data will allow anaesthetists to compare device performance that will inform purchase and usage decisions of bougies, ensuring optimum benefit for safe practice

Mechanical performance assessment system for endotracheal tube introducers using motion detection and object tracking
Failure to secure the airway with an endotracheal tube in a timely manner on induction of anaesthesia can lead to serious complications, including death. Equipment design and selection can often contribute to procedure success or failure, although current equipment does not always provide optimum solutions. Most anaesthetists consider endotracheal tube introducers (bougies) essential equipment; however, there are many different types available, with little relative performance data to inform choice. To date, no performance assessment system exists that is capable of assessing the shape retention properties of bougies. This paper discusses the design development process of the Shape Retention Testing System (SRTS) that utilises motion detection, object tracking and image processing to assess the relative performance of bougie introducers

Performance analysis system for endotracheal tube introducers: standardising for success
Equipment design and selection can contribute to the success or failure of difficult airway management. The design of medical devices/testing systems completed by multidisciplinary design teams that include healthcare professionals can significantly influence device success or failure. This paper presents an overview of the design tasks used to develop the Shape Retention Testing System (SRTS) for the assessment of bougie introducers. By using a multidisciplinary design team that includes healthcare professionals, critical design tasks such as design criteria generation, product design specification (PDS) generation, focused design approaches, and iterative design processes have ensured essential feedback is collected to influence the SRTSâs design and manufacture
