PRESSURE-SENSING NECK BLOOD VESSEL IDENTIFICATION INSTRUMENT AND IDENTIFICATION METHOD THEREFOR

The present invention discloses a pressure-sensitive neck blood vessel identification instrument and an identification method therefor. The identification instrument includes: a protective cover, a display screen fixed on the top of the protective cover, and a contact rod floatingly connected below the protective cover, with one end of the contact rod exposed. On the outside of the protective case, the other end conducts pressure to the pressure sensor at the bottom of the display through a buffer member built into the protective case. This method uses a pressure-sensitive neck blood vessel identifier, combined with a marker and a pressure data chart, to quickly and accurately mark the projection of the carotid artery and vein on the surface of the neck skin, thereby facilitating jugular vein puncture and improving accuracy and safety. The invention is low in cost, simple in principle and easy to operate. At the same time, it can efficiently trace the trend curves of arteries and veins and reduce the situation of accidentally entering arteries during venipuncture.
