Hanyang University AIMD created the first artificial intelligence-based video laryngoscope in Korea. They achieved this through the collaboration of the engineering and medical departments of Hanyang University. Professor Lim Tae-ho (Department of Emergency Medicine) designed the AI-based video laryngoscope, while Professor Kim Jong-soo (Institute for Software Convergence) developed the AI algorithm, and Professor Song Yeong-tak (Department of Emergency Medicine) was responsible for product development and market entry.

Laryngoscope is a piece of equipment used to perform intubation for patients unable to breathe on their own, or to secure the breathing of a patient that needs general anesthesia. Around 85,000 intubations take place inside a hospital every year, and there are an average of 24,000 cardioplegic patients annually. However, putting the tube down one's throat and finding the respiratory tract is difficult. In order to achieve more than 90 percent success rates, a person who has over 50 successful intubations must perform the act. This also means that the 119 ambulance workers usually cannot, and in reality do not use the tubes even in urgent circumstances.
Hanyang University AIMD first started developing the next generation laryngoscope to meet the needs of paramedics and emergency medical technicians (EMTs) who could not use the laryngoscopes because of their costly price and the risk for unsanitary use. The imported video laryngoscopes cost around 15 million won, which makes them hard to access. Also, the ambulance crew faces difficulty attempting to sterilize the equipment with every use, which brought up the need to make the parts that require handling to be disposable.

These drawbacks of video laryngoscopes made the AIMD team take the lead in creating an advanced AI-based video laryngoscope (i-LRYNGO). These new innovations proudly represent three major functions: AI airway identification, wi-fi mirroring, and fast booting (under five seconds). The AI-based video laryngoscope is expected to adopt a function that automatically captures the airway. The wi-fi mirroring function will be designed to share the screen of the laryngoscope with several smartphones in real time, in part for educational purposes. Lastly, the booting is based on the average of four seconds it takes to start the program, which is crucial as AI-based video laryngoscopes are designed to be used in emergencies, thereby causing the necessity for speedy access to the tool.

Apart from the three major functions, the equipment was built for more convenient use by reflecting data from Size Korea to adopt the appropriate shape for the size of Korean hands. Also, the curved structure of the blade in the laryngoscope was readjusted by taking into account the traits of Korean mouth structure. The AIMD team continuously made adjustments and supplementation following the feedback from ambulance workers. As of now, the final product is complete, and licensing from the Korea Food and Drug Administration has been approved.
AIMD has already received many awards such as the 2018 Laboratory Startup Demo-Day Excellence Award, the first HY Innovation Award grand prize, first place in 2018 Lion Cup Competition, and more. While laryngoscopes are used in various emergencies, the Artificial Intelligence-based video laryngoscope is expected to increase the survival rate of emergency patients through its AI algorithm, mirroring, and fast booting time.
