Nowadays, many bedridden and speechless patients stay in hospitals and have to stay in nursing homes. Nurses and caregivers in hospitals must understand each patient individually and meet their needs. The study aims to inform the patient's needs to the relevant staff via a wireless environment without the need to talk. The main purpose of the study is to understand what the patient needs from the different hand movements he makes. The electromyography (EMG) examination method was used to understand hand movements. Two types of electrodes are used for EMG examination: needle and surface. Although the two electrodes have advantages and disadvantages compared to each other, surface electrodes are more preferred. Because, unlike needle electrodes, surface electrodes allow EMG signals to be collected without disturbing the patient. In the study, the "Oymotion EMG Armband" device was used to collect EMG signals. The device can collect EMG signals and send the signals wirelessly to the microcontroller card via Bluetooth communication. Two separate Arduino UNO boards containing ATmega328P microcontroller were used for wireless communication and mobile interface connections. To facilitate patient-nurse communication, an interface for mobile devices has been designed by the operation of the device. The patient's hand movements are evaluated in the microcontroller to which EMG signals are transmitted, and the patient's wishes are visualized through the mobile interface. With the internet of medical things based (IoMT) system, patients can easily communicate their wishes with simple hand gestures without the need to speak, and nurses and caregivers can immediately understand the patient's wishes with the mobile interface and carry out the procedures quickly.
