Vascular management device using electrical stimulation

Vascular Management Device Combining Dual-Patch Blood Flow Velocity Comparison and Electrical Stimulation Optimization

This technology is a vascular management device consisting of a terminal unit that senses blood flow velocity at two points on a single blood vessel using first and second patches and calculates vascular abnormalities based on the difference between the two velocities, and a pad unit that applies electrical stimulation to the vessel when an abnormality is detected.

Existing vascular management methods struggle to quantitatively assess blood flow velocity abnormalities, and even when electrical stimulation is applied, the intensity, frequency, and cycle cannot be optimized for individuals, leading to inconsistent stimulation effects.

This technology automatically searches for optimal conditions where the difference between the two blood flow velocity peaks is minimized by varying the intensity, frequency, and cycle of electrical stimulation. It can be applied to wearable vascular health management devices to provide personalized blood flow improvement.

Key Features:

• A patch unit consisting of a first patch attached to a first point on a blood vessel to sense blood flow velocity, and a second patch attached to a second point on the same vessel to sense blood flow velocity.
• A terminal unit that quantitatively calculates vascular abnormalities based on the difference between the first and second blood flow velocities received from the patch unit.
• A pad unit attached near the blood vessel between the first and second patches to apply electrical stimulation when a vascular abnormality is detected.
• A pad control unit that operates the pad unit by determining the optimal conditions that minimize the difference between the two blood flow velocity peaks while varying the intensity, frequency, and cycle of the electrical stimulation.
