This negative pressure blood drawing needle adopts the shape of concave red blood cells on both sides, which is round and lovely and effectively relieves children's fear when drawing blood. At the same time, children's participation is added to reduce children's fear. Children gently squeeze the middle of the round cake, then trigger the mechanism and automatically pump into a vacuum state.

Just a young man who is afraid of drawing blood. Ha, seeing here, he is still afraid. This is my personal feeling.
I think there will still be babies crying, not because the design is not good, but because they start crying when they see the doctor as soon as they enter, and they can't stop crying at all
The design idea is very good, but there is a fatal problem. The normally printed square barcode label cannot be pasted on the round cake so well, and it is easy to fold. This is the gap between the idea and the actual landing. Hope to hit the face ~
Interesting
I feel very practical. I hope I can produce and use it in my life in the future.
This needle is quite cute, but I don't know if it sticks to the skin???
Great!
The concept of turning the operation of the injection tube into a rounded concave-convex shape is very creative, and it is more perfect if there is a design to prevent misoperation
What I fear most since I was a child is also injections
I am the girl who received the injection and cried in the picture.
