摘要:
A breath monitoring device including a flow sensor that may measure a respiration rate of a patient and to identify apnea events in the patient's breathing; a CO 2 sensor that may operate at low power and to measure a CO 2 concentration in the patient's breath; and a processor that may integrate the measurements obtained from the flow sensor and the CO 2 sensor and to determine the respiratory status of the patient based on the integration.

Aspects are generally directed to systems and methods that integrate contactless electric field detectors to measure biophysical signals generated by a body. In one example, a biophysical sensing system includes a sensing assembly including an array of contactless electric field detectors, each of the contactless electric field detectors being configured to sense a corresponding component of an electric field generated by a body, a control system to receive sensor data indicative of the components of the electric field sensed by each of the contactless electric field detectors, the control system being configured to generate an estimate of the electric field based on the sensor data, and a feedback system coupled to at least the control system, the feedback system including at least one feedback interface, the feedback system being configured to operate the feedback interface to provide feedback based on the estimate of the electric field.
摘要:
A system, device and method for automatically and remotely acquiring sensor data from a wearable patch mounted on a patient. An example device implemented as a wearable patch includes a sensor assembly comprising a plurality of sensors configured to detect a corresponding plurality of sensory modalities and generate electrical signals representing the sensory modalities. A signal converter receives the electrical signals from the plurality of sensors and converts the signals to sensor data signals comprising a data representation of at least one of the electrical signals. A communications interface communicates the sensor data signals to a sensor data processing system.
摘要:
A method for determining proper placement of a sensor pod on a patient comprising: performing a first quality control procedure on a detection device, wherein the first quality control procedure generates a tone and wherein each of said sensor pods measures and compares the measured sound to a predetermined measurement in real-time; wherein a sensor pod is determined to have met quality control if said sound is within 10% of the predicted measurements; performing a second quality control procedure on said sensor pods, wherein said sensor pods measure sounds on a patient; wherein the system, once engage, detects sounds from the sensor pods and compares the detected sounds in real-time to a predicted sound based on the fluid flow vessel, and wherein said method provides for an audio or visual alarm when said sensor pod is not detecting the predicted sounds, indicating an improper location for the sensor pod.
摘要:
A system for improving a health status of a person by analyzing and applying frequency information at a person is disclosed. The frequency information could be collected from an audio sample, or could be collected via feedback frequencies occurring when a test frequency is applied at the person. The system analyzes the collected frequency information to determine a status of the patient, for example a fundamental frequency of the person and/or a weak frequency of the person. Based upon the frequency information, the system generates a protocol to implement one or more frequencies at the person, for example sonic frequencies, light frequencies, and/or vibrational frequencies. Depending upon which frequencies are implemented, the state of the person can be improved.
摘要:
A monitoring and alerting system can be used in any condition with a respiration component. Respiratory symptoms as well as supporting physiological functions are tracked against the user' s baseline and alerts the user when there is a worsening trend. The system is self-contained in a wearable that detects and logs the signals, analyzes them and generates alerts. The wearable is untethered during use and may be attached to the body in various manners, such as with adhesives, clothing, clips, belts, chains, necklaces, ear pieces, clothing circuits or the like. Information can further be transmitted both wirelessly and via wire to devices, cloud storage, or the like.
摘要:
A fetal phonocardiogram system featuring an array of acoustic sensors designed to be temporarily affixed to a pregnant patient to convert the vibrations associated with a fetal heartbeat and/or fetal movement into a signal. The signal can be amplified and transferred to a processing element for filtering non-fetal sounds in order to resolve the fetal heartbeat. The filtered signal can be used in conjunction with an array of multiple acoustic sensors to locate a fetal position relative to the array.
摘要:
Methods and apparatus for guiding medical care based on sensor data from the gastrointestinal tract are described utilizing an apparatus which can be used with enteral feeding. Generally, the apparatus includes an elongated body having a length configured for insertion into a stomach and at least one pair of electrodes located along the length of the elongated body and positionable for placement within the stomach. A controller in electrical communication with the at least one pair of electrodes is included and the control may also be configured to measure a conductivity or impedance between the pair of electrodes and to determine a gastric residual volume of the stomach based on the measured conductivity or impedance.
