摘要

The apparatus to take blood samples from animals, with minimum invasion, uses blood-sucking bugs (W) within a container (1) with a perforated wall (1.1) placed against the animal's skin (F). The bug sucks blood through the perforated wall, and is then secured in place by a moving wall (1.2) when engorged, for the collected blood to be extracted from its abdomen by a hollow needle (3).
