Abstract:
1. A portable real time infusion monitoring device for detecting an infusion dripping flow rate in response to the movement of each infusion droplet dripping in an infusion dripping chamber and alarming when infusion dripping abnormalities occur during an intravenous therapy, the said monitoring device comprising: a capacitor, made of two polar plates that are placed in communication with an infusion catheter above an infusion dripping chamber; an capacitance measurement unit electrically connected to the said capacitor and configured to detect periodical capacitance value changes between the said capacitor during an intravenous therapy; a micro control unit (MCU) electrically connected to the capacitance measurement unit that is configured to determine the infusion dripping flow rate by measuring the frequency of the capacitance change between the said capacitor during an intravenous therapy and compare the infusion dripping flow rate with a predetermined baseline values to determine infusion dripping rate abnormalities and generate an alarming signal when infusion abnormalities are detected; a LCD displayer electrically connected to the said MCU, to display the infusion dripping flow rate during an intravenous therapy and generate a warning message when infusion dripping rate abnormalities are determined; a LED light electrically connected to the said MCU that is designed to flash in response to each infusion droplet dripping in the infusion dripping chamber in order to facilitate monitoring the intravenous therapy in a dark environment and remains lit when infusion dripping flow rate stops or abnormalities are determined; a buzzer electrically connected to the said MCU to instantly alarm when infusion dripping flow rate abnormalities are determined.
