Blood pressure measuring apparatus with respiratory variation and venous pressure
A recently granted patent (Publication Number: US11903684B2) discloses a blood pressure measuring apparatus that includes a cuff, pressure control unit, detection unit, analysis unit, and determination unit. The apparatus is designed to obtain arterial pressure, respiratory variation on the artery waveform, and venous pressure through a one-time blood pressure measurement. The method involves specific processes to obtain diastolic and systolic blood pressure, respiratory variation, and venous pressure within a predetermined time frame of 140 seconds. Additionally, the apparatus includes a display unit and display control unit to visualize the obtained values on a two-dimensional graph, providing a comprehensive overview of the measurements.
Furthermore, the patent also covers a blood pressure measuring method that involves detecting pressure waveforms, obtaining arterial pressure, respiratory variation, and venous pressure based on the detected waveforms. The method includes specific processes for obtaining each parameter within a set time frame. Notably, the method emphasizes the importance of accurate and timely measurements, with specific intervals and time periods defined for obtaining each parameter. The apparatus and method described in the patent aim to provide healthcare professionals with a reliable and efficient tool for measuring blood pressure and related parameters in a living body, ensuring comprehensive and accurate results within a short duration.
