ABSTRACT:
The puncturing device for blood vessels has an ultrasound probe (20) which permits location, based on the Doppler effect, of the blood vessel (50). By means of a guide duct (13) the puncturing needle (30) can be directed at least approximately coaxially relative to the beam transmitted by the probe (20). Puncturing must be performed in a sterile manner. To this end, according to the invention, the probe is enveloped in a sterile covering, this covering having a sterile coupling member (1) in which a reflector (12) for the ultrasound beam and a needle guide duct (13) are situated. The coupling member (1) may be part of the covering; alternatively, however, it may be designed as an attachment to be placed on the covering. The sterile covering with the coupling member (1), which is intended to be used once only, eliminates the need for time-consuming, repeated gas sterilization of the puncturing device.
