PURPOSE: To propose a supersonic-doppler-probe that can be used together with a hollow needle for sticking the needle into blood vessel. CONSTITUTION: Hollow needle 5 is stuck into blood vessel after its place is probed by a supersonic-doppler-probe. Needle guide 17 pierces through probe head 11 concentrically. Hollow needle 5 pierces through needle guide 17 to stick into blood vessel at an extremely high accuracy. Supersonic-doppler-probe 1 extends to wedge shape within the scope of probe head 11 and needle guide 17, and the probe 1 is distanced transversely from the stuck needle. |
