AI Technical Summary
Technical Problem
Existing blood pressure monitors with heart reference units are cumbersome, difficult to manufacture, prone to malfunction, and limit patient mobility due to fluid-filled tubes and electrical connections, leading to inaccurate readings.
Method used
A stand-alone heart reference unit with two separate fluid columns, each with one end positioned near the patient and the other ends connected away from the patient, allowing components to be routed conveniently, and a differential pressure transducer to adjust for hydrostatic pressure differences.
Benefits of technology
The solution provides accurate blood pressure readings by adjusting for hydrostatic pressure while minimizing device complexity, enhancing patient mobility, and reducing manufacturing difficulties.
