Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a multipurpose pediatric artery positioning pen. Background technique [0002] The arteries pulsate regularly with the contraction and relaxation of the human heart and the rise and fall of blood pressure. In the field of pediatric medical care, blood gas analysis monitoring and femoral artery blood sampling require arterial localization. At present, pediatric medical staff mainly rely on clinical experience and anatomical position to locate arteries, but there are certain errors and inaccurate positioning, which increases the difficulty of puncture. The success rate of clinical arterial puncture is low, and puncture failure often increases the pain of children and brings certain pain. medical risks. [0003] The patent with the application number CN201621017783.5 discloses an arterial puncture auxiliary positioning pen, which includes a pen body and a pen head. A cavi...
