This study aimed to develop a device that detects and monitors the blood glucose level of a diabetic patient. The device automatically releases the D50 water when it detects hypoglycemia (low blood glucose level) and sends data to the doctor through GSM. When it detects hyperglycemia (high blood sugar level), it shuts down both the D50 water and the dextrose. This study utilized two methods namely experimental development and descriptive approach. Experimental development was employed in making the prototype design. On the other hand, descriptive approach, which involved assessment of the functionality of the device by 30 purposively chosen evaluators, namely, medical specialists, medical technologists, nurses, engineers, and diabetic patients. Based on the functionality test, the device exhibited very high efficiency in terms of its automation of D50 drip during hypoglycemia, and turning off the D50 water and dextrose during hyperglycemia, communication and requisition of data using GSM, wireless transmission of data with transceivers, and the efficiency of the graphical user interface. However, limitations also came to light, and it is recommended that these limitations be addressed to anyone who may develop similar device in the future.
