Re:Sucking in blood and air holes

[ME]

I’m sorry. I suppose I did not clearly communicate my blood question. Not worried about sealing in blood, but more along the lines of sucking blood into the sealing device. Do you think that it is an issue that some gets in the machine. I will not try to make a habit of doing so, but in the mean time while im perfecting the technique, it may not be avoidable. Thanks.
