Desain Sistem Pengatur Laju Aliran Infus Menggunakan Sensor Droplet Berbasis Arduino Uno Si KHAIRUL IHSAN 1903113079
ABSTRACT
A research has been conducted to help the medical staff at the hospital. One treatment that is often done is intravenous infusion therapy. Infusion devices are useful in administering medication, nutrition, and hydration to patients. The purpose of this study is to calculate and regulate the flow rate of the infusion into patient's body. Measuring the number of infusion drops is quite simple; it is done by counting the pulses from the recipient, but it is still done with high measurement accuracy. The liquid released from the infusion will be converted into droplets, which are then detected by three optocoupler sensors arranged around the detection area. This research uses a microcontroller called the Arduino UNO. The Arduino UNO provides results received from the sensor and coded using the Arduino IDE software to be displayed on a 16x2-character Liquid Crystal Display (LCD) and can be saved to an SD card for further analysis. The samples used in this study were Sodium Chloride (NaCl), Water, and Ringer's Lactate. The calibration tools carried out were droplet sensor testing, servo motor testing, and RTC module testing. The detection results on the droplet sensor configuration produce an average error value for each sample, namely 2.414% NaCl, 1.178% water, and 1.328% Ringer's lactate. The results showed that the average accuracy level of the sensor was 98.36%. The results obtained from this research can be implemented to determine whether the tool is suitable for use or not. The testing conducted is still in the laboratory scale, and in the future, this system can be developed for monitoring infusions in real-time over a longer period of time and using more complex data processing features.
