Lab Animal Infusion
Large Animal Ambulatory
Ambulatory infusion systems utilize an implanted or wearable syringe pump, allowing the animal to move freely. This system eliminates the need for tethers, enabling animals to explore and exhibit more natural behaviors. With proper preparation, animals, including primates, can be group-housed while receiving ambulatory infusions.
Compared to tethered infusion, ambulatory models reduce both human interference and animal stress. Animals can be dosed with minimal human intervention and may be monitored and controlled remotely, which is crucial for certain studies, such as safety pharmacology assessments.
Ambulatory Infusion System for Rabbits
Maintain healthy and freely-moving rabbits with our ambulatory infusion systems.
Ambulatory infusion studies in rabbits require a lightweight pump due to the animal’s smaller size. As a result, tethered infusion systems are also a common approach. Our team can assist you in customizing options for your protocol, including catheters, access systems, pumps, and more, based on your specific needs.
