Hi guys, just a quick question about my needles and injecting here.
On my pins at the opposite end of the pointy bit, there is like a little ball of air/an empty void that is between the pin and the part where you attach to the syringe. Does anyone know what the purpose of this ball is?
And sometimes when I inject, I aspirate and see no blood, inject, then remove the needle and the little air ball thing has a very small droplet or 2 of blood. What gives here? Am I not aspirating properly or something?
Thanks
Snoot
