Unmet Need:
Blood pressure monitoring is extremely important in a clinical setting for understanding the current state of a patient, as well as for the diagnosis of various conditions. Many current devices have limitations in accuracy in obese patients, patients with severe vascular disease, and during episodes of low blood pressure. Additionally, they lack applicability in individuals with low or non-pulsatile flow, such as those with left ventricular assist devices or on veno-arterial extracorporeal membrane oxygenation. Thus, there is an imperative need for a non-invasive blood monitoring device that could accurately measure vital sign regardless of patients’ existing condition.
Technology Overview
Researchers at Johns Hopkins University have developed an automated, non-invasive blood pressure monitoring cuff which uses 3D ultrasound and colorflow, pulse wave and continuous Doppler processing for the measurement of blood pressure. This device will be the first automated blood pressure cuff designed to measure blood pressure in patients with low or non-pulsatile flow, which would increase efficiency and effectiveness as, compared to current standard of procedure, it doesn’t require highly trained clinician to operate the device and the results generated are more reliable.
Stage of Development
Individual portions of the device are undergoing testing. A prototype is under development.
