Single developing line group (U):Tie a developing line to the ultrasound probe and place the ultrasound probe so that the developing line is located in the middle of the median cubital vein. Then al
Double developing line group (D):The two shadow lines were tied to the ultrasound probe so that the inner diameter of the double shadow line = the outer diameter of the ozonated autohemotherapy punctu
Median line group (M):The ultrasound median line is displayed, the ultrasound probe is placed so that the median line is located in the middle of median cubital vein, the puncture needle is aligned wi
Standard out-of-plane puncture group (U):Classical conventional out-of-plane ultrasound-guided puncture of the median cubital vein, without any visualization or localization line guidance. Entering th
