Abstract: The present invention relates to a portable non-invasive hemodynamic monitoring system that obtains various parameters related to cardiovascular function, including blood oxygen saturation, perfusion index, pulse wave, electrocardiogram, respiration, bioimpedance, etc., and analyzes the collected data to obtain parameter data such as cardiac output, non-invasive blood pressure, cardiac index, pulmonary arterial pressure (PAP), etc.

Abstract: The present disclosure relates to an apparatus for predicting a hemodynamics parameter being conventionally obtained from an implanted sensor or catheter (invasive sensor), e.g., pulmonary artery pressure, based on noninvasive biosignals, such as electrocardiographic (ECG), impedance cardio graphic (ICG), phonocardiogram (PCG), pulse oximetry plethysmograph (PPG). The present disclosure also relates to a method of feeding multiple noninvasive biosignals and/or general inputs into an AI model or AI models to predict a hemodynamics parameter, such as pulmonary artery pressure, which is conventionally obtained from an implanted sensor or catheter.

Abstract: An electrode unit for measuring physiological electrical activity in a subject is provided. The electrode unit comprises a base material, an electrode, a connector, a conductive ribbon, a space limiting module, and a film. The base material includes a first base material layer and a second base material layer. The electrode is inserted in an opening of the first base material layer. The conductive ribbon is placed on the first base material layer. The conductive ribbon connects the electrode and the connector. The connector is placed inside the space limiting module. The space limiting module is placed inside an opening of the film. The second base material layer is placed on top of the conductive ribbon. The film is placed over the first base material layer and the second base material layer.
