Abstract

A coupling part (1) can be slid on an exchangeable ultrasonic Doppler probe (2). The material inside the housing (11) is a transmission mass (12) and transmits ultra-sound in an optimum manner. Embodiments for conventional probes and for special divisible probes are possible. In order to carry out ultrasonic Doppler examinations in sterile conditions also, the coupling part (1) may be supplied in a sterile package. The coupling part may be provided with a needle guide in order to be used as a punction aid. These variants may be laterally removed from the needle after punctioning.
