Design of wireless infusion monitor based on Bluetooth 4.0

Based on design of the technologies of infrared photoelectric monitor spectroscopy measurement, this article gives a design of wireless infusion monitor based on Bluetooth 4.0 (BLE4.0) low energy technology. It works with smart mobile Application (APP). The wireless infusion monitor uses a Radio Frequency (RF) integrated chip CC2540 as Micro Control Unit (MCU). The signal of received infrared diode is sampled by Analog-to-Digital Converter (ADC) and processed with the threshold filtering. Then it comes to the information of infusion. The data is packaged in a custom format and send to the smart mobile APP via BLE 4.0. The infusion monitor is responsible for monitoring the infusion process in real time. A sound alarm is issued when the wireless infusion monitor detects a dangerous condition. The APP is responsible for computing the infusion information and displaying it. At the end of this paper, the feasibility of the wireless infusion monitor is verified through practical test.
