PROBLEM TO BE SOLVED: To provide simulated blood usable for a flow phantom for ultrasonic diagnostic devices over a long time since the simulated blood is safe to organisms and harmless to the natural environment with no change over time in the density thereof and sonic speed therein nor no precipitate and floating of a resin powder.SOLUTION: The simulated blood for flow phantoms for ultrasonic diagnostic devices comprises a suspension in which a resin powder with a density of 1.05×10(kg/m) is dispersed in an aqueous solution, in which the aqueous solution is an aqueous solution with a density of 1.05×10(kg/m) including water, a water-soluble polyhydric alcohol and a water-soluble silicone. The simulated blood such that the density of the simulated blood and sonic speed in the simulated blood comply with an IEC international standard is formed by using the three-component aqueous solution including a water-soluble silicone in which the sonic speed decreases with increase in the concentration of the silicone. The precipitating and floating of the resin powder is prevented by making the density of the resin powder the same as that of the three-component aqueous solution. |
