    Abstract: The disclosure provides a drug monitoring device assembled outside an intravenous infusion set for intravenous infusion, including a fastening assembly, a monitoring sensor mounted on the fastening assembly, and a monitoring module. The monitoring sensor includes at least one turbidity light transmitter for emitting first light beams and at least one light receiver. The first light beams change in directions when passing through the intravenous infusion set. The at least one light receiver generates a first sensing signal in response to receiving one of the first light beams. The monitoring module generates a turbidity warning message when a number of the first sensing signals received during an estimation time period is greater than a turbidity warning threshold.

    Abstract: A lung sound monitoring device is provided. The lung sound monitoring device includes an acoustic sensor and a processor. The acoustic sensor is configured to capture the chest cavity sound of a subject at a first monitoring position on the subject and convert the chest cavity sound into a first chest cavity sound signal. The processor is configured to receive the first chest cavity sound signal and perform a filter process to obtain a first lung sound signal, and convert the first lung sound signal into a first lung sound spectrum using time-domain frequency-domain conversion. The processor acquires a first intensity index according to the first lung sound spectrum, and outputs a prompt signal according to the first intensity index to indicate whether the first monitoring position is a qualified monitoring position.

    Abstract: Provided is a heart rate activity detecting method based on dynamic images. The method includes tracking a moving object. Preset brightness is determined based on an ambient condition. An image of the moving object is captured to generate a corresponding RGB color space, which is then converted to an image color space with adjustable brightness. The brightness of the image color space is adjusted according to the preset brightness to generate an image with corrected brightness, which is then converted to a RGB color space with the corrected brightness for calculating a heart rate activity of the moving object. The disclosure is capable of addressing the issue of an unstable light source by adjusting the brightness of the dynamic images, and then calculating the heart rate activity of the moving object according to the dynamic images. A heart rate activity detecting system based on dynamic images is also provided.
