ABSTRACT A non-sterile ultrasonic-Doppler unit (400/500/600) for locating and punctur- ing blood vessels is at least partly packed sterile with a sterile device (100/200/300), such that it can be used in a sterile field. The probe (600) of ultrasonic-Doppler unit, that features a slot (610) orientated in the axis of the ultrasonic field, is thus inserted into a sterile cap (300), that a guide tube (340) for the puncturing needle penetrating this cap comes to lie in the slot ofthe probe. The device according to the invention envelopes the probe com- pletely, such that the non-sterile ultrasonic probe (600) does not contaminate the puncturing needle, the patient's skin nor the surgeon. Additionally the cap (300) can contain a coupling member, which guarantees an ultrasonic coupling between the probe (600) and the patient's skin, such that the surgeon need not add any gel. All parts of the device according to the invention are dispos- able single-use articles. (Fig. 3a)
