  • Patent number: 11844590
    Abstract: The invention provides a neck-worn sensor (referred to herein as the ‘necklace’) that is a single, body-worn system that measures the following parameters from an ambulatory patient: heart rate, pulse rate, pulse oximetry, respiratory rate, temperature, thoracic fluid levels, stroke volume, cardiac output, and a parameter sensitive to blood pressure called pulse transit time. From stroke volume, a first algorithm employing a linear model can estimate the patient's pulse pressure. And from pulse pressure and pulse transit time, a second algorithm, also employing a linear algorithm, can estimate systolic blood pressure and diastolic blood pressure. Thus, the necklace can measure all five vital signs along with hemodynamic parameters. It also includes a motion-detecting accelerometer, from which it can determine motion-related parameters such as posture, degree of motion, activity level, respiratory-induced heaving of the chest, and falls.

  • Patent number: 11823779
    Abstract: A medical device data back-association system, apparatuses, and methods are disclosed. In an example embodiment, a server receives first medical device data from a medical device including a device identifier and stores the first medical device data to an unassociated record in a database after determining that there is no association between the device identifier and any patient identifier or medication order identifier. While the medical device is administering the medication to a patient, the server receives an identifier message including at least two of the device identifier, the patient identifier, and the medication order identifier. The server creates an identifier association between a medical record of the patient and the medical device using the identifier message. The server uses the identifier association to store subsequent medical device data from the medical device to the medical record of the patient.

  • Patent number: 11793460
    Abstract: The invention provides a sensor for measuring both impedance and ECG waveforms that is configured to be worn around a patient's neck. The sensor features 1) an ECG system that includes an analog ECG circuit, in electrical contact with at least two ECG electrodes, that generates an analog ECG waveform; and 2) an impedance system that includes an analog impedance circuit, in electrical contact with at least two (and typically four) impedance electrodes, that generates an analog impedance waveform. Also included in the neck-worn system are a digital processing system featuring a microprocessor, and an analog-to-digital converter. During a measurement, the digital processing system receives and processes the analog ECG and impedance waveforms to measure physiological information from the patient. Finally, a cable that drapes around the patient's neck connects the ECG system, impedance system, and digital processing system.

  • Patent number: 11752245
    Abstract: A system and method are disclosed for the automated collection of dialysis data. An example method includes receiving and aggregating dialysis data comprising a fill volume amount and a drain volume amount for at least one continuous ambulatory peritoneal dialysis (“CAPD”) cycle. The method also includes calculating an amount of ultrafiltration removed for each CAPD cycle by subtracting the fill volume amount from the drain volume amount for the respective CAPD cycle, and storing ultrafiltration data that is indicative of the amount of ultrafiltration removed as part of the aggregated dialysis data. The method further includes determining or receiving an indication that a dialysis machine is connected. After the dialysis machine is connected, the method includes transmitting the aggregated dialysis data to the dialysis machine to enable the aggregated dialysis data to be combined with additional dialysis data generated by the dialysis machine for determining total dialysis data.
