The Baroreceptor Collar is used to investigate autonomic nervous system research questions as it provides a non-invasive method of stimulating carotid sinus baroreceptors via oscillatory neck pressure and/or neck suction. The Technavance Solution incorporates three-stage vacuum motors, high-flow solenoid valves and piezo-resistance pressure sensors to provide a fully-automated research platform for such investigations. The system’s user-friendly software enables researchers to fully-customize neck pressure / neck suction test protocols, which can be triggered manually or via a third-party ECG. Repeatable transitions between pre-defined pressure and suction set points are easily and automatically achieved using the system’s proprietary control electronics. Results can be exported from the software or fed directly into third-party data acquisition systems.
