Open-Motion
Low intensity infrared device for blood flow and blood volume measurement
Research Use Only; pre-FDA
Open-Motion 3.0
The Open-Motion diagnostic platform using low intensity near-infrared light to measure blood flow, blood volume, and micro-motions deep under the tissue surface. Ready to use out of the box, and also as an open source architecture that allows for customization to suit a wide range of research needs. Standardized design features ensure that clinical studies conducted with these tools can generate critical data to inform the development of future portable, low-cost medical devices.
Key Features
A diagnostic platform designed for noninvasive measurement of blood flow, blood volume, micro-motions, and oxygenation deep beneath tissue surfaces.
- Wearable, modular design for a wide range of applications
- Microsecond laser pulses with high sensitivity and minimal exposure
- Integrated machine learning for real-time classification and analysis
- Compliance with IEC 60601-1; ISO 13485 certification in process
- Complete platform or OEM hardware/software components
- Research use only; pre-FDA
Large Vessel Occlusion Study
The Openwater optical blood flow monitor outperformed both RACE and LAMS for the detection of LVO in patients presenting for acute stroke evaluation. A clinically relevant increase in sensitivity was observed for the Openwater blood flow monitor without a cost to specificity, which ultimately yielded fewer false negatives and false positives.
