Masimo‘s patent involves a method for determining blood pressure measurements using an inflatable cuff. The system assigns a confidence level to the measurement and displays the result based on the confidence level. If confidence is low, the system will take another measurement before displaying the result. GlobalData’s report on Masimo gives a 360-degree view of the company including its patenting strategy.

A recently granted patent (Publication Number: US11925445B2) discloses a method for determining blood pressure measurements using a patient monitor in communication with an inflatable cuff. The method involves receiving inflatable cuff configuration parameters, determining a first blood pressure based on inflated pressure, assigning a confidence level to the measurement, and deciding whether it meets a threshold level. If the confidence level is below the threshold, a second blood pressure is determined based on deflated pressure, and the results are displayed on a monitor. The method also includes steps for filtering data signals, identifying maximum magnitudes, and associating pressures with systolic readings.

Furthermore, the patent details additional features such as using a replaceable gas reservoir or portable inflation system for cuff inflation, displaying waveforms of data signals associated with blood pressure measurements, determining confidence levels based on noise levels in data signals, and communicating with electronics of the gas reservoir. The method also involves monitoring the pressure level within the gas reservoir, displaying notifications if thresholds are not met, and recording usage data in the reservoir's electronics. Overall, the patent outlines a comprehensive approach to accurately and confidently determine blood pressure measurements using innovative technology and monitoring systems.
