摘要： Systems and methods for monitoring heart failure status in a patient are discussed. A medical-device system includes a storage device to store a correspondence between one or more heart failure comorbidities and corresponding one or more heart failure detection settings, and a heart failure detector circuit to detect a heart failure status of the patient. The heart failure detector circuit receives physiological information and heart failure comorbidity information of the patient, determines a detection setting for the patient based on the received comorbidity information and the stored correspondence, and detect a heart failure status using the received physiological information and the identified detection setting. A therapy circuit can deliver or adjust a heart failure therapy in response to the detected heart failure status.

摘要： A method or system for noninvasive evaluating and monitoring of abnormal cardiopulmonary vibrations includes obtaining one or more signals using one or more noninvasive heart and/or lung vibration signal sensors or transducers that provide a measure of physiological effects that are correlated with cardiopulmonary functions, recording, by a processor and one or more heart and/or lung vibration signal sensors or transducers for turbulence recordings between a first and second cardiopulmonary sounds, analyzing the turbulence recordings for unique vibration signatures associated with cardiopulmonary disease by searching deviations from an average beat, and presenting an assessment of cardiopulmonary disease upon finding that the deviations are above a predetermined threshold. In some embodiments, the system and method further include seeking a largest mean absolute error of a specific segment between an average beat and each beat from a subject to provide a murmur level indicative of cardiopulmonary disease.

摘要： A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment, including either suspending or adjusting turn schedule based on various types of patient movement. Compliance with Head-of-Bed protocols can also be performed based on actual patient position instead of being inferred from bed elevation angle. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

摘要： The disclosure relates to systems and methods for noninvasively performing cardiac auscultation. In some implementations, a method includes: performing, using a BP cuff of a BP cuff system, a blood pressure measurement of a subject to obtain one or more blood pressure values corresponding to the subject; inflating, based on the one or more blood pressure values corresponding to the subject, the BP cuff to a subject specific pressure value; capturing, using the BP cuff system, while the BP cuff is inflated to the subject specific pressure value, a pulse pressure waveform signal associated with an artery of the subject; obtaining a sound waveform signal associated with a heart valve of the subject by filtering the pulse pressure waveform signal to extract sound components associated with the opening or closing of the heart valve; and analyzing the sound waveform signal to identify characteristics of the heart of the subject.

摘要： A compliance-based cleaning device includes an internal housing, a sanitization chamber coupled to the internal housing and configured to receive a piece of equipment to be cleaned, and an ultraviolet lamp. The sanitization chamber transitions between an open position and a closed position by rotating about an axis within the internal housing. The ultraviolet lamp is located in proximity to the sanitization chamber and is configured to perform a cleaning process on the piece of equipment in response to the sanitization chamber entering the closed position.

摘要： A method includes obtaining test criteria for a monitor configured to be attached to a user; obtaining reference data; determining, based on the test criteria and the reference data, a detached state of the monitor. The determining the detached state includes performing a set of tests indicated in the test criteria. The set of tests includes a first test corresponding to a first power consumption by the monitor; and a second test different from the first test. The second test corresponds to a second power consumption by the monitor, and the second power consumption is larger than the first power consumption. The method further includes automatically modifying, in response to the determining the detached state, an operating mode of the monitor.

摘要： A non-invasive and convenient method and apparatus for approximation of left ventricular end diastolic pressure (LVEDP) can be used in both hospital/clinic environments and nursing home or home environments. The method and apparatus use non-invasive sensors and a new “cardiac triangle” computational method to obtain an approximation of LVEDP. The computational method uses hemodynamic and electrocardiogram (ECG) waveforms as input, which can be collected by a portable device or devices.
