An intravenous infusion detection device is provided in the invention. The intravenous infusion detection device includes a radar device, a digital signal processing (DSP) device and a controller. The radar device includes a plurality of transmission antennas and a plurality of receiving antennas. The transmission antennas are configured to transmit a plurality of radar signals and the receiving antennas are configured to receive a plurality of reflection signals corresponding to the radar signals. The DSP device transforms the plurality of reflection signals received from the plurality of receiving antennas into a plurality of one-dimensional (1D) waveform diagrams, transforms the plurality of 1D waveform diagrams into a three-dimensional (3D) diagram, and obtains a drip level of a drip bag according to the 3D iagram. The controller is couplted to the radar device and obtains the drip level of the drip bag from the DSP device and calculates the flow rate of the intravenous infusion according to the drip leve
