Groundbreaking innovation combines SunTech‘s cuff-based blood pressure with Valencell’s PPG-based blood pressure monitoring technology

New technology set to transform patient safety, care, and comfort

Morrisville, NC (February 8th, 2021) SunTech Medical Inc., the leading provider of clinical-grade blood pressure (BP) measurement technologies and devices, and Valencell Inc., the leader in highly accurate biometric sensors for wearables, today announce proof of concept for DeltaTrak™ technology. The patent-pending innovation combines the gold-standard accuracy of SunTech’s Advantage™ cuff-based BP and its superior motion tolerance capabilities, with continuous interpolative BP monitoring from Valencell’s optical PPG (photoplethysmography) technology between cuff readings. The proof of concept will allow for joint development discussions with medical device manufacturers interested in integrating this capability into their products.

Julian Mullaney, SunTech’s Vice President of R&D, commented: “The SunTech and Valencell collaboration has resulted in a groundbreaking solution that has not been possible before. We’re excited about the possibilities for this combination of motion-tolerant BP and PPG technology, particularly in the high-acuity clinical and veterinary market segments that can benefit from truly continuous monitoring.”

“Cuff BP measurements must be spaced apart in time to allow for blood flow, and patient comfort. The DeltaTrak™ technology is designed to provide comfortable BP monitoring continuously during and in between those clinical-grade cuff measurements,” explained Paul Matsumura, SunTech’s Sr. Director of Research and Technology.

DeltaTrak™ technology is designed to trigger a new cuff reading if the continuous signal violates pre-set guardrails.  This functionality is intended to address the currently unmet need for continuous BP monitoring in situations where continuous cuff inflation is simply not feasible, such as hemodialysis, emergency medicine, OR and ICU, ambulatory BP studies, cardiac rehabilitation, and sleep. In clinical settings like sleep and hemodialysis, fewer cuff inflations could also provide a more comfortable patient experience.

SunTech and Valencell have developed a solution to an industry-limiting problem that has remained unsolved for decades – continuous BP monitoring combined with clinical-grade accuracy in high acuity situations. We hope this technology will address a critical unmet need.”

This innovation is the result of a multi-year collaboration between SunTech and Valencell, announced in January 2020. SunTech Medical’s parent corporation, Halma plc., is also an investor in Valencell and played an integral role in the collaboration.   

“The cooperation with Valencell has been really productive,” said Rob Sweitzer, President of SunTech Medical.  “Their data science team and knowledge of PPG tech, combined with SunTech’s experience in clinical markets and our BP algorithm experts, will result in valuable new solutions to improve patient safety.”
