Wireless Doppler Ultrasound Patch
The Wireless Doppler Ultrasound Patch is a specialized, low-profile device designed for continuous, non-invasive hemodynamic monitoring. Operating at 4 MHz, this patch employs continuous-wave Doppler principles with a fixed-angle transducer securely adhered over the common carotid artery (CCA). Its wireless design and flexible straps allow for comfortable, long-term wear, providing clinicians with a real-time window into blood flow dynamics. It is clinically validated for tracking critical parameters such as end-diastolic velocity (EDV), pulsatility index, and carotid flow time (CFT), making it an essential tool for optimizing Left Ventricular Assist Device (LVAD) settings, assessing fluid responsiveness, and diagnosing conditions like pericardial tamponade in both ICU and ambulatory settings.
