Abstract

A hemostatic method is performed as follows: A) An at-puncture hemostatic pressure is applied to a puncture in a blood vessel via a main geometric side, and at least one off-puncture hemostatic pressure is applied to at least one position away from the puncture via at least one auxiliary geometric side, wherein the off-puncture hemostatic pressure acts on the blood vessel either directly or indirectly. B) During the hemostatic process, an ongoing flow velocity of the blood in the blood vessel is obtained and is reduced to lower than a normal flow velocity in the blood vessel by applying the at-puncture and off-puncture hemostatic pressures simultaneously, wherein the at-puncture and off-puncture hemostatic pressures are lower than a systolic pressure in the blood vessel.
