The puncture aid is applicable regardless of the shape of an ultrasonic probe or the axial direction thereof when performing ultrasonically guided puncturing, and is also applicable when not performing ultrasonically guided puncturing, such as the landmark method. The puncture aid is capable of preventing erroneous puncturing of the carotid artery and the like by enabling, for example, stable insertion of the puncture needle along the placement line direction of the jugular vein. |
