Abstract
A two-component monitoring device and system for monitoring blood pressure from a patient is disclosed herein. The two-component monitoring device includes a disposable component and a main component. The disposable component features: i) a backing structure having a first aperture; and ii) first and second electrodes, each electrode connected to the backing structure and including an electrical lead and a conductive electrode material, and configured to generate an electrical signal that passes through the electrical lead when the conductive electrode material contacts the patient. The main component includes: i) first and second connectors configured to connect to the first and second electrical leads to receive the first and second electrical signals; and ii) an optical component comprising a light source that generates optical radiation and a photodetector that detects the optical radiation. The optical component inserts into the first aperture of the disposable component. The main component optionally includes an acoustic sensor. The system utilizes a processing device, connected to the monitoring device by a cable which receives and processes a plurality of signals to determine real-time blood-pressure values for the patient.
