Abstract

Now in health technology benefitable by intravenous therapy (IV) to used replace liquid and can balancing electrolyte in body. But in now using intravenous therapy (IV) uncontrol and unmonitoring can make people was flebitis (blood artery infection caused by chemical and drug irritation.In that condition then we proposed a intravenous therapy drop rate control based on PID. In that reseach will be expended in four work process. In first process is readability intravenous therapy drop who will do by photodiode sensors, in second process is to control automatic intravenous therapy drop rate used with PID controller who will do by Motor Servo when get instruction from smartphone, in third process is readability blockage Intravenous therapy liquid or doesn’t based on there are or no drip intravenous therapy and the fourth process is early warning system for Intravenous therapy liquid as one way to anticipation for Intravenous therapy liquid wear out on patient. Based on experiment shown that control automatic intravenous therapy drop rate had a good result. Getting it being showed of setting time value that can be reached is 16 second And error steady state value is 13 drips

Abstract

trocardiogram (ECG) is a medical test to detect heart abnormalities by measuring the electrical activity produced by the heart, as the heart contracts. ECG can help diagnose various health conditions such as cardiac arrhythmias, heart enlargement, heart inflammation (pericarditis or myocarditis), and coronary heart disease. In general, detection of heart disease can only be done in a hospital using ECG. The system that is used now also cannot be used to automatically detect the patient's illness when using the ECG. In this paper the author makes a tool that can detect portable heart signals. From the detected heart signal we can determine that the heart's condition is normal or there is an abnormality in the heart. The heart signal was detected from the electrode clamp sensor mounted on the right arm (RA), left arm (LA) and right leg (RL). The signal from the sensor is amplified with an amplifier amplifier circuit so that it can be read by the STM32F4 ARM microcontroller. The microcontroller processes the signal from the sensor and will be displayed on the Computer Application. Connection between Microcontroller and PC using a Bluetooth serial connection. The final appearance in this final project can display the shape of the ECG signal and determine that the heart is normal or abnormal. Based on the test results obtained from the comparison of ECG devices made with the ECG type BTL-08 SD there is an error of 1.06%.
