<p>The invention proposes a Doppler ultrasound probe (1) which can be used directly in conjunction with a hollow needle (5) for puncturing a blood vessel. The hollow needle (5) can be placed after the desired blood vessel has been located by the Doppler ultrasound probe (1). A needle guide (17) leads concentrically through the probe head. The hollow needle (5) is pushed through the needle guide (17). It can thus be placed very accurately. The Doppler ultrasound probe (1) can be opened in wedge-shaped fashion in the region of its probe head (11) and the needle guide (17), so that it can be extended from the sides of the needle that has been placed. <IMAGE></p> |
