All the needles(针）and sryinges针管 are disposable in Canada.Only the knives and scissors
used in the Operation theatre are reusable. There is disposable knife used for certain
procedure. Don't worry for that I have worked in Hospital for so many years.
They fix the needles and Sryinges before patients walk in to save time. But they should not
do that as it will carry certain risk of infection although it is minimum. Not to worry for that. The safe blood taking needles have a small butterfly attached to the end and they are
capped with a small plastic cap in front, that part should not be removed before clients read.That's all. No worries.
