Zynex has patented a noninvasive method and apparatus for detecting blood volume imbalances in mammals. The method involves obtaining baseline physiological measurements, computing a baseline blood volume index, and monitoring real-time measurements to detect imbalances. The system can detect changes as low as 10% of the normal blood volume. GlobalData’s report on Zynex gives a 360-degree view of the company including its patenting strategy. Buy the report here.

A recently granted patent (Publication Number: US11890079B1) discloses a noninvasive method for detecting blood volume imbalances in mammalian subjects. The method involves obtaining baseline physiologic measurements of various parameters such as heart rate, skin temperature, and peripheral blood flow over a period of time, computing a starting blood volume index, and then calculating a real-time blood volume index based on differences between baseline and real-time measurements. The algorithm used includes coefficients for weighting each difference value, allowing for the detection of blood volume imbalances as low as 10% of the subject's normal total blood volume. The method also includes displaying the real-time blood volume index and any changes from the starting value on an electronic display.

Furthermore, the patent includes details on the apparatus used for this method, which comprises noninvasive sensors capable of obtaining baseline and real-time physiologic measurements at the subject's extremities. The sensors communicate with an electronic display and an integrated circuit to compute the real-time blood volume index and display it accordingly. The apparatus includes various configurations for the placement of electrodes, such as on thigh bands, ankle bands, arm bands, or even in a blood pressure cuff. Additionally, an alarm system is integrated into the apparatus to alert when the real-time blood volume index reaches a predetermined threshold, enhancing the monitoring capabilities for detecting blood volume changes in mammalian subjects.
