Abstract: A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a ‘fiducial’ marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.

Abstract: The invention provides an IV system for monitoring a patient that is positioned on the patient's body. The IV system includes: 1) a catheter that inserts into the patient's venous system; 2) a pressure sensor connected to the catheter that measures physiological signals indicating a pressure in the patient's venous system; 3) a motion sensor that measures motion signals; and 4) a processing system that: i) receives the physiological signals from the pressure sensor; ii) receives the motion signals from the motion sensor; iii) processes the motion signals by comparing them to a pre-determined threshold value to determine when the patient has a relatively low degree of motion; and iv) process the physiological signals to determine a physiological parameter when the processing system determines that the motion signals are below the pre-determined threshold value.

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.

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.

Abstract: The invention provides a system for characterizing fluids in a tissue located in a portion of a patient. The system features an impedance system that includes a current-injecting electrode that injects an electrical current into the portion of the patient and a signal-measuring electrode that measures an impedance signal affected by the injected electrical current and an amount of the fluids. At least one of the electrodes includes an alignment feature that, during use, is aligned on the portion using a marking on the portion. The system also includes a processing system that receives the impedance signal from the impedance system or a signal determined from it. It then processes the signal to determine a parameter related to the degree of fluids in the tissue. The marking, for example, can be a permanent or semi-permanent marking, such as a tattoo.

Abstract: The invention provides an intravenous (IV) dressing system that helps secure an IV catheter to a patient while simultaneously using embedded peripheral venous pressure (PVP), impedance, temperature, optical, and motion sensors to characterize properties of the IV system (e.g., infiltration, extravasation, occlusion) and the patient's physiological parameters (e.g., heart rate, SpO2, respiration rate, temperature, and blood pressure). Notably, the system converts PVP waveforms into arterial BP values (e.g., systolic and diastolic blood pressure).
