Clot catchers

Hello everyone!

So my question is what do you use for clot catchers in your NICU department if you use clot catchers and if not do you see any issues?  We were given some samples from a vendor before I gained management of the devices and I am having a hard time now finding the devices to reorder.  The ones I thought were correct came to be the NOVA clot catchers for syringes.  If these can be used for capillary samples as well could you help me learn how to?

Thanks!
