Abstract

Measuring body temperature depends on the type of thermometer and measured body area. A thermometer placed on the tympanic membrane is considered ideal because the tympanic membrane and hypothalamus have arterial blood supply originating from the carotid artery (neck). Therefore, it is considered directly close to the core temperature. The Tympani Thermometer with external storage can facilitate the doctor's performance in diagnosing patients. This tool is designed using the MLX90614 sensor as a passive infrared sensor that can receive infrared energy from the tympanic membrane. The study aims to design a tympani thermometer. It compared the measurement results of the designed tool with ear thermometers that have been calibrated to get the error value. Based on the results, this prototype works well and has an error of 0.7°C in the left ear and an error of 0.24°C in the right ear.

Abstract

Embedding is an anatomical pathology laboratory device that is very important for producing quality slices and is also a device used to process paraffin tissue, so that the tissue can be cut with higher precision using a microtom (slicer). From the process of melting paraffin crystals using a manual heating process with bunsen flame heaters (fire heaters) so that the paraffin crystals can be transformed from the crystal into liquid. While paraffin crystals that have been processed from the crystal to liquid form are poured into the mold and left to freeze. In this case, an embedding system device will be made equipped with heating and cooling. The temperature used for the liquefaction process is 50ï‚°C while the temperature for cooling is 17ï‚°C. After making the process of making device, experiment device, and retrieving data, the error percentage results were 0.016% at the heating temperature and 0.08% at the coolant temperature, and the percentage of heating samples obtained in the sample was 61.3%, while the percentage samples for parts coolers get a value of 92%

Abstract

ECG or Electrocardiograph is a tool to find out the electrical activity of the heart in patients. Electrocardiogram (ECG) is a graphic result records electrical potential resulting from by heartbeat, (Mervin J. Goldman, 1990). ECG recording very useful to know present certain hypertrophy, arrhythmia, pericarditis, for example potassium electrolyte disturbances. Tool this be named generator signal ECG. Tool the generator signal ECG functioning for produce the signal Electric heart in adult patient sand to check ECG error or no. So that it can ease technical electro medic in maintenance medical equipment periodically. The tool utilizes IC 14521 as oscillator or signal generator and using IC 14 017 as a shift register who has responsibility to remove from pin 1 to pin the other. The benefits of the ECG signal generating device so that technical electro medic easy and not difficult in check ECG without must using patients. So this tool as a form clone of the human heart. The tool such as a patient simulator. Based on the results of laboratory tests that have been done with the author concluded that, ECG signal generating device to function properly so that produce form of mock patient's heart signal that shown monitored oscilloscope in the waveform display P, Q, R, S, T.
