Blood flow velocity management device using visual stimuli

HMD device for managing blood flow velocity using flickering black-and-white spot visual stimuli

This technology is a blood flow velocity management device consisting of a terminal unit that senses blood flow velocity at the common carotid artery and radial artery using attached patches and calculates the difference between the two, and an HMD unit that provides flickering black-and-white spot visual stimuli to minimize this difference.

Existing blood flow management methods have limitations in that they cannot directly improve imbalances between body parts through visual means, and they fail to optimize the brightness or flickering frequency of stimuli according to an individual's condition.

By varying the brightness and flickering frequency of black-and-white spots to find the optimal conditions that minimize the difference between the two peak blood flow velocities, this technology can be applied to wearable healthcare devices to improve blood flow imbalances through visual stimulation alone.

Key Features:

• A patch unit consisting of a first patch attached to the user's common carotid artery to sense blood flow velocity and a second patch attached to the radial artery to sense blood flow velocity.
• A terminal unit that quantitatively calculates the difference between the first and second blood flow velocities received from the patch unit in real time.
• An HMD unit that provides visual stimuli corresponding to black-and-white spots flickering at a predetermined frequency to minimize the difference between the two blood flow velocities based on the calculated quantitative data.
• An HMD control unit that operates the HMD unit by varying the brightness and flickering frequency of the black-and-white spots to determine the optimal conditions that minimize the difference between the two peak blood flow velocities.
