Rodent and Small Animal Retro-Orbital Bleeding Device

A more controlled way of performing an ROB to retrieve blood samples from rodents or small animals without negatively impacting the studies.


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 biomarkers 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.
