Rodent and Small Animal Retro-Orbital Bleeding Device

In order for the FDA to approve human trials, researchers must show efficacy of their drug in rodent or small animal models. These studies almost always require a blood sample from the animals to monitor key bio-markers during the study. Yet, the most preferred method of drawing blood, from the submandibular vein, can negatively impact the study by inadvertently reducing eating and drinking as well as locomotor and sensorimotor behavior. This can ruin an entire study and waste thousands of dollars. An alternative sampling method is retro-orbital bleeding (ROB). However, this technique is currently being performed “free hand” by veterinary/biomedical research professionals. This lack of control and precision increases the time it takes to complete the ROB, as well as risks injury to both the animal and the researcher. This device offers a solution to this expensive problem by creating a more controlled way of performing an ROB.
