摘要： An apparatus useful for the rapid collection of blood from a subject (e.g., the vein of a bovine subject) and dispensing the blood therefrom into a collection device includes: (a) a capillary body having a capillary chamber formed therein, with the chamber having an inlet and outlet, and with said chamber configured to draw blood therein through the inlet by capillary action; (b) a hollow barrel connected to the chamber outlet; (c) a plunger positioned in the barrel; and (d) a hollow needle connected to the capillary body, with the hollow needle in fluid communication with the capillary chamber through the capillary inlet, so that blood can be rapidly drawn into the capillary chamber through the needle by the combined action of vein pressure (or other pressure, if present, such as arterial pressure) and capillary action.
