Abstract
In a syringe for ultrasonically aided penetration of arterial or venous vessels the transmitter and the receiver are arranged in the piston. This simplifies manipulation and, particularly if a physiological saline solution is simultaneously injected to directly couple the ultrasound to the soft parts surrounding the vessel, enables vessels even in anatomically difficult positions to be localized simply and without the danger of complications.
