Dried biological fluid spot punch device and related methods |
摘要 |
A dried biological fluid spot punch device includes a tube, a frit, and a filter disposed on the frit. The tube includes a main section and a distal section adjoining the main section. The main section includes a proximal tube end circumscribing a proximal tube opening, and the distal section includes a distal tube end circumscribing a distal tube opening. The distal section further includes a distal tube having a tapered inside diameter that reduces from the main section to the distal tube opening. The frit is disposed in the distal section at a distance from the distal tube opening and fixed in position by frictional contact with the distal tube wall. The punch device may also include a punching tool. The punching tool may include a body engaging the tube at the proximal tube end and an ejection mechanism configured for disengaging the body from the tube. |
