  • Publication number: 20250040812
    Abstract: A blood pressure measurement device includes a substrate, a protrusion portion, an image sensor, a first light source, a second light source, and a control and processing unit. The first light source projects a first light toward the base plat. A finger presses the protrusion portion, and the image sensor captures an image of a bright area. The processing unit calculates a number of light-receivable pixels of image sensor and compares with a number of pixels able to receive light of image sensor to obtain a ratio value, and determines whether the finger has enough pressure. The second light source projects a second light toward the substrate, penetrating the substrate and the finger skin to be reflected by a blood vessel. The image sensor captures an image of a changed volume of the blood vessel, and the control and processing unit calculates the systolic or diastolic pressure.
