Infusion Liquid Level Detection Tool Using IR Sensors and Photodiode Based on Microcontroller

摘要

Infusion device is a means for injecting certain chemical fluids, nutritional fluids, blood transfusions and chemotherapy to patients. The fluid enters the body through veins. The use of infusion is actually not so problematic if the patient can be controlled and monitored periodically for a short time by the nurse. Some problems present when there is lack of human resources in the hospital or nurse’s negligence. One of the problems is the administration of intravenous fluids. When the fluid runs out, there is no sign or warning directly sent to the nurse. Therefore, a system to control and monitor the level of infusion fluid is necessary to design. The system is designed to detect the level of infusion fluid using a level sensor and a microcontroller as the data processor and hardware regulator. This system sends messages to nurses by short message text application. The result of the research showed that when the infusion fluid is about to finish, the system notifies the nurse by sending an SMS.
