The present invention relates to a blood flow improving device, the power button and the exhaust valve is formed on the front surface and the inner side of the bottom is provided with a fastening hole and a through hole formed in the center of the bottom, the outer case is covered with a silicone material, the suction port And a discharge port formed therein, and a discharge port communicating with an intake port located in the through hole provided in the exterior case is connected to the motor, so that the air flowing from the intake port by the operation of the motor is moved through the discharge port, and a battery is provided. The main body is formed of a battery storage case is formed and the battery mounting portion for supplying power to the motor, and a cylindrical hole is formed through the inside and connected to one side of the through hole is connected to the hanging hole is coupled A cylindrical body formed with a pair of auxiliary hooks to be fitted to the other side of the cylindrical body, Is the central aperture are removable available urethane material of the decor and the ring, is coupled to the fitted decorated ring through hole is formed in the center it consists of a compression ring of the possible removal of silicon material. Therefore, according to the present invention, clogged or narrowed corpus cavernosum due to blood vessels, erectile dysfunction, premature ejaculation, etc. of terminal tissues far away from the heart such as fingers or toes is smoothly pierced to allow normal blood circulation, repetitive expansion and contraction movements. It has the effect of forming strong blood vessels and spongy bodies, and has the advantage of stability and portability compared to electric rechargeable by supplying power using batteries, and can reduce production cost by simple configuration. It does not have to be a burden, it is a very useful design that can be expected to improve the usability by easy and simple operation structure.본 고안은 혈류
