[0002] Rat jugular vein blood sampling is a common blood sampling technique in animal experiments. Rat jugular vein blood sampling relies on the naked eye recognition of the anatomic landmarks of the jugular vein (the outer edge of the sternocleidomastoid muscle, the line connecting the mandibular angle to the sternal notch) by the operator, and needs to be combined with palpation to determine the venous pulsation point. The success rate is significantly affected by the differences between animals (body size / position variation can reach 2-3 mm).
