Abstract

The use of medical equipment in the world of health is very much needed, one of which is an electrostimulator which can be used to help recovery in post-stroke patients. Electrostimulators can be made with several conditions, namely: controller, stimulator, and electrodes. Apart from that, there are 4 parameters needed for the electrostimulator, namely 1) Pulse Amplitude, 2) Pulse Width, 3) Pulse Shape, 4) Pulse Frequency. In this electrostimulator, it is highly recommended to use a surface electrode, apart from being a non-invasive electrode, this electrode also provides comfort and is easy to use. Judging from this, an innovation was carried out, namely making an electrostimulator with the choice of 2 modes, namely continuous and intermittent. The research procedure was carried out in several stages starting from preparing tools and materials, measurements and functional tests. The results of the research are a design for an electrostimulator therapy device with a power supply connected to a microcontroller and displayed on an LCD. The test results showed that the error percentage at the power supply input was 5.9%, the power supply output was 3%, and the buzzer output was 0%. The results of testing and analysis of the tool on the oscilloscope showed that the error percentage at frequency values of 2 Hz, 4 Hz, 5 Hz, 7 Hz and 8 Hz was 0.05%, 0%, 2%, 4% and 8% respectively. Based on the results of this research, it can be concluded that the tool is as desired and good to use.

Abstract

The development of electromedical technology encourages the creation of safer and more efficient surgical tools, one of which is electric cautery. This study aims to design and build an electric cautery prototype based on an Arduino Uno microcontroller equipped with a Liquid Crystal Display (LCD) to display current (0–6 A) and frequency (0–50 Hz) parameters in real-time. The research method uses a Research and Development (R&D) approach, starting from the design stage, prototyping, to functional testing and simple clinical trials on chicken tissue. The test results show that the tool has a high level of accuracy, with a maximum relative error of 3.9% in current and 1.6% in frequency, still within the tolerance limits of the IEC 60601-2-2 standard. Simple clinical trials show that the tool is able to cut tissue well while coagulating so that the wound area remains neatly closed. These findings indicate that Arduino-based electric cautery with real-time monitoring features can be an innovative and safer alternative compared to conventional devices, although further clinical trials with stricter medical standards are still needed.
