Designing and Prototyping of an Electromechanical Ventilator based on Double CAM operation Integrated with Telemedicine Application
In this paper, we proposed to design a new model of mechanical ventilator based on the Ambu bag automation for the patient who is unable to take breath normally. Here we have automated an Ambu bag for air supply whose inlet is connected with an oxygen cylinder and environmental air and outlet is connected to lung patient. The project device includes a robotic operator which can operate an Ambu bag continuously by compressing and decompressing it. The robotic operator is a Computer Aided Manufacturing (CAM) arm that is controlled by a single microcontroller for operating on the Ambu bag from outside. It has a great advantage of using a single adult Ambu bag to deliver necessary air to all aged lung patients by setting different controlling modes with respect to age with reducing the necessity of pediatric Ambu bag and infant Ambu bag. By considering all of the physiological parameters, we have added three modes namely Adult mode, Pediatric mode, and Child mode. Each mode is included by different respiratory rate and tidal volume to be friendly with their corresponding subject. The proposed device can detect the air pressure and temperature from the Ambu bag outlet to make feedback for preventing the lung harm of the patient and display the parameters using an LCD. All medical data can be transferred via a communication protocol to an Android or iOS phone for telemedicine purposes in real time. The overall system is portable, small in size (45cmx25cmx35cm) low weighted, time efficient, and cost effective. There is no need for training or the study of an operator about the proposed system to handle the device for the benefit of automation of the device.
