Abstract
An ultrasonic Doppler probe which can be used together directly with a hollow needle for puncturing a blood vessel is disclosed. The hollow needle can be set once the blood vessel sought has been located with the ultrasonic Doppler probe. A needle guide passes concentrically through the probe head. The hollow needle is pushed through the needle guide. It can thus be set with great accuracy. The ultrasonic Doppler probe can be opened in the shape of a wedge in the vicinity of its probe head and the needle guide, permitting it to be removed to the side from the set needle.
