Pressure sensing neck blood vessel recognition instrument and recognition method thereof

The invention discloses a pressure sensing neck blood vessel recognition instrument and a recognition method thereof.The recognition instrument comprises a protective sleeve, a display screen fixed to the top end of the protective sleeve and a feeler lever connected to the lower portion of the protective sleeve in a floating mode, and one end of the feeler lever is exposed to the outer side of the protective sleeve; and the other end transmits the pressure to a pressure sensor at the bottom end of the display screen through a buffer piece arranged in the protective sleeve. According to the method, the projection of the jugular artery and vein is quickly and accurately marked on the surface of the neck skin by utilizing a pressure sensing neck blood vessel recognition instrument in cooperation with a marking pen and a pressure data graph, so that jugular vein puncture is facilitated, and the accuracy and the safety are improved. The device is low in cost, simple in principle and easy to operate, meanwhile, the
