  • System and method for monitoring the life of a physiological sensor
    Patent number: 11317837
    Abstract: Aspects of the present disclosure include a sensor configured to store in memory indications of sensor use information and formulas or indications of formulas for determining the useful life of a sensor from the indications of sensor use information. A monitor connected to the sensor monitors sensor use and stores indications of the use on sensor memory. The monitor and/or sensor compute the useful life of the sensor from the indications of use and the formulas. When the useful life of the sensor is reached, an indication is given to replace the sensor.

  • Medical monitoring system
    Patent number: 11298021
    Abstract: The present disclosure includes a host device that is part of a patient monitoring system. The host device can provide an improved, organized, uncluttered, and graphically-rich display that presents an integrated display of real-time patient data and alarms from multiple integrated or non-integrated devices, such as patient monitors, ventilators, anesthesia gas machines, or intravenous (IV) pumps. The host device may provide a supplementary display for the patient data collected by the multiple devices and present information, such as comprehensive real-time patient status, historical trends, or alarm indicators, in an organized manner for particular clinical scenarios. The one or more displays can be central to a care team for a patient, and the care team can together simultaneously view and act upon the information presented.

  • Wellness analysis system
    Patent number: 11289199
    Abstract: A wellness analyzer is in communications with sensors that generate real-time physiological data from a patient. The wellness analyzer is also in communications with databases that provide non-real-time information relevant to a medical-related assessment of the patient. In a diagnostic mode, a monitor layer inputs the sensor data and adjunct layers input the database information. Adjunct layer logic blocks process the database information so as to output supplemental information to the monitor. Monitor logic blocks process the sensor data and the supplemental information so as to generate a wellness output. In a simulation mode, a simulator generates at least one parameter and the monitor generates a predictive wellness output accordingly.

  • Patient monitoring system
    Patent number: 11272852
    Abstract: A method of determining blood pressure measurements includes inflating a cuff, receiving an indication of pressure inside the cuff during inflation, determining a blood pressure based at least in part on the received indication, assigning a confidence level to the blood pressure, and determining whether the confidence level satisfies a threshold confidence level. Based at least on a determination that the confidence level satisfies a threshold confidence level, the method can include causing a display to display the blood pressure. Based at least on a determination that the confidence level does not satisfy a threshold confidence level, the method can include deflating the cuff, receiving an indication of pressure inside the cuff during deflation, determining another blood pressure, and causing a display to display a blood pressure.

  • Autonomous drug delivery system
    Patent number: 11259745
    Abstract: An autonomous drug delivery system advantageously utilizes physiological monitor outputs so as to automatically give a bolus of a rescue drug or other necessary medication when certain criteria and confidence levels are met. An emergency button is provided to manually trigger administration of the rescue drug. The rescue drug may be an opioid antagonist in response to an analgesia overdose, a hypotensive drug to avert an excessive drop in blood pressure or an anti-arrhythmia drug to suppress abnormal heartbeats, to name a few.

  • System for displaying medical monitoring data
    Patent number: 11241199
    Abstract: A first medical device can receive a physiological parameter value from a second medical device. The second physiological parameter value may be formatted according to a protocol not used by the first medical device such that the first medical device is not able to process the second physiological parameter value to produce a displayable output value. The first medical device can pass the physiological parameter data from the first medical device to a separate translation module and receive translated parameter data from the translation module at the first medical device. The translated parameter data can be processed for display by the first medical device. The first medical device can output a value from the translated parameter data for display on the first medical device or an auxiliary device.

  • Non-invasive blood pressure measurement system
    Patent number: 11234602
    Abstract: A system for non-invasively determining an indication of an individual's blood pressure is described. In certain embodiments, the system calculates pulse wave transit time using two acoustic sensors. The system can include a first acoustic sensor configured to monitor heart sounds of the patient corresponding to ventricular systole and diastole and a second acoustic sensor configured to monitor arterial pulse sounds at an arterial location remote from the heart. The system can advantageously calculate a arterial pulse wave transit time (PWTT) that does not include the pre-ejection period time delay. In certain embodiments, the system further includes a processor that calculates the arterial PWTT obtained from the acoustic sensors. The system can use this arterial PWTT to determine whether to trigger an occlusive cuff measurement.

    Abstract: A perfusion trend indicator inputs a plethysmograph waveform having pulses corresponding to pulsatile blood flow within a tissue site. Perfusion values are derived corresponding to the pulses. Time windows are defined corresponding to the perfusion values. Representative perfusion values are defined corresponding to the time windows. A perfusion trend is calculated according to differences between representative perfusion values of adjacent ones of the time windows.

  • Plethysmograph variability processor
    Patent number: 11229374
    Abstract: A plethysmograph variability processor inputs a plethysmograph waveform having pulses corresponding to pulsatile blood flow within a tissue site. The processor derives plethysmograph values based upon selected plethysmograph features, determines variability values, and calculates a plethysmograph variability parameter. The variability values indicate the variability of the plethysmograph features. The plethysmograph variability parameter is representative of the variability values and provides a useful indication of various physiological conditions and the efficacy of treatment for those conditions.

  • Adaptive alarm system
    Patent number: RE49007
    Abstract: Systems and electronic processes for reducing electronic alarms in a medical patient monitoring system. For example, a system for reducing electronic alarms can include an optical sensor and one or more hardware processors in electronic communication with the optical sensor. The one or more hardware processors can be programmed to measure oxygen saturation values of a patient over a first period of time, determine if at least one oxygen saturation value obtained over the first period of time exceeds a first alarm threshold, determine whether a first alarm should be triggered based on the determination that the at least one oxygen saturation value obtained over the first period of time exceeds the first alarm threshold, determine a second alarm threshold to be applied during a second period of time subsequent to the first period of time, the second alarm threshold replacing the first alarm threshold.

  • Physiological trend monitor
    Patent number: RE49034
    Abstract: A physiological trend monitor has a sensor signal responsive to multiple wavelengths of light transmitted into a tissue site. The transmitted light is detected after attenuation by pulsatile blood flow within the tissue site. A processor has an input responsive to the sensor signal and a physiological parameter output. Features are extracted from the physiological parameter output. Criteria are applied to the features. An alarm output is generated when the criteria are satisfied.
