[0002] The skills of pediatric scalp vein puncture mainly include selecting a suitable puncture site. Generally, the frontal median vein, anterior temporal vein, temporal vein and sutural vein can be selected. And before puncture, the hair on the scalp surface needs to be shaved off, which is beneficial to the exposure of the skin and more conducive to operation. At the same time, a suitable pillow also needs to be selected. Generally, a relatively small needle needs to be selected. When inserting the needle, the needle should form an angle of 15 degrees with the scalp. Generally, the bevel of the needle tip needs to face upward. The right hand also needs to hold the needle, and the left hand needs to fix the skin. Then directly puncture the skin into the vein. After puncturing into the vein, obvious blood return can be seen. Finally, use adhesive tape for fixation to avoid falling off during use.
[0003] However, when medical staff perform scalp vein puncture on children clinically, due to the young age of the patients, poor compliance, non-cooperation, crying, sweating, the manual clamping and fixing effect by family members and medical staff is poor, and it is easy to slip during the puncture process, increasing the puncture time of the patients, improving the puncture difficulty of medical staff, resulting in a decrease in the puncture success rate, and even medical accidents may occur.
