Design of Robotic System for the Mannequin-Based Disinfection Training

The purpose of skills training is making trainers master skills correctly and utilize them efficiently in their work and life. As one of the most important skills training of nurses, the disinfection training is often trained on the medical mannequin. The effect of the mannequin-based disinfection training is often not ideal because of the lack of the feedback information generated by the disinfection training of novice nurses. To solve this problem, we design a new robotic system for the mannequin-based disinfection training by transforming the medical mannequin. The robotic system is made up of the force processing module, the location processing module and the data fusion module. The force processing module handles the vertical downward force applied by the forceps with sterilized cotton ball on the medical mannequin, and transmits the force filtered by the moving average filter to the data fusion module. The location processing module transmits the plane position information applied by the forceps to the data fusion module. The data fusion module integrates the location information and the force information to generate the pressure and the three-dimensional coordinate information of the forceps exerted on the medical mannequins. After the test of the West China Medical School, the output data of the newly designed robotic system meets the requirements of the sensing sensitivity and working range for the mannequin-based disinfection training. The new robotic system could also be utilized in other medical training fields, e.g. the massage training, the acupuncture training and so on.
