  • VASCULAR MONITORING SYSTEM, DEVICE AND METHOD
    Publication number: 20260123905
    Abstract: A Doppler blood flow monitoring device includes a signal generation module, a signal reception module, a signal filtration module, a signal conversion module, at least one speaker, and a user interface. The signal generation module is configured to send a signal to a probe positioned in a probe receptacle on a vascular coupler positioned about a patient's vessel. The signal reception module is configured to receive a return signal from the probe. The signal filtration module is configured to filter the return signal. The signal conversion module is configured to convert the filtered signal into an audible indication and a visual indication corresponding to a characteristic of blood flow in the patient's vessel. The at least one speaker is configured to emit the first audible indication. Additionally, the user interface is configured to display the visual indication.
