Abstract:
Breast cancer is a cancer with the highest prevalence in Indonesia and one of the factors that trigger lymphedema. Lymphedema caused by disruption of the lymph flow due to removal of some lymph nodes during breast cancer surgery causes swelling of the upper or lower extremities. Compression pump therapy is a therapeutic technique for controlling swelling. This research aimed to design and development of pressure pump based on microcontroller with good performance. The lymphedema pumps were made with 3 chamber handcuffs which had 4 variations of pressure values, i.e. 20mmHg-30mmHg, 30mmHg-40mmHg, 40mmHg-50mmHg, and 50mmHg-60mmHg which could be selected using push button. The reading of the air pressure value on the handcuff used the MPX5050GP pressure sensor. The air control system uses Arduino UNO ATMega 328 microcontroller. The result of performance test of pressure sensor to output voltage showed correlation coefficient 99.93%. The result of pressure calibration showed 99.96% linea
rity. The assembled lymphedema pump had the characteristic of a chamber which was able to inflate and deflate sequentially from distal to proximal with the mean pressure on each chamber. So, the assembled pressure pump has a candidate as lymphedema pump therapy.
