Abstract:
According to an aspect, there is provided a method of determining the respiration rate of a subject, the method comprising obtaining a signal from a sensor that is worn or carried by the subject; analyzing the signal to determine a plurality of values for a breathing-related feature; forming a histogram from the plurality of values for the breathing-related feature, the histogram comprising a plurality of groups, with each group having an associated count that is the number of occurrences of a value or values for the breathing-related feature corresponding to the group; applying a weighting to the count associated with each group to form weighted counts; and determining the respiration rate from a mean of the histogram with the weighted counts.
Abstract:
An upper airway stimulator for treating obstructive sleep apnea is described. In some embodiments, the upper airway stimulator monitors the phase difference between ribcage expansion and abdomen expansion to detect apneic events and stimulates to alleviate those events. In some embodiments, the upper airway stimulator applies primary stimulation when an apneic event is not detected and secondary stimulation when an apneic event is detected. In some embodiments, the upper airway stimulator applies primary stimulation when the patient is not in an apneic position and secondary stimulation when the patient is in an apneic position.
Abstract:
Die Erfindung betrifft ein Erfassungsgerät sowie ein Verfahren zur Erfassung und Auswertung eines hinsichtlich der Atmung einer schlafenden Person indikativen Messsignals im Zusammenhang mit der Observation schlafbezogener Atmungsstörungen. Weiterhin betrifft die Erfindung auch Instrumente zum Abgriff von hinsichtlich der Atmung eines Patienten indikativen Signalen. Der Erfindung liegt die Aufgabe zugrunde, Lösungen bereitzustellen, die es ermöglichen, eine besonders aussagefähige Untersuchung hinsichtlich des Auftretens schlafbezogener Atmungsstörungen, insbesondere in der gewohnten Umgebung des Betroffenen, durchzuführen. Gemäß einem ersten Aspekt der vorliegenden Erfindung wird diese Aufgabe erfindungsgemäß gelöst, durch ein mobiles Erfassungsgerät mit einer Sensoreinrichtung zur Erfassung eines hinsichtlich eines nasalen Atemgasstromes indikativen Nasalstromsignales, und/oder eines oralen Atemgasstromes indikativen Atemgasstromsignals; und einer unter Einschluss einer Speichereinrichtung gebildeten elektronischen Datenverarbeitungseinrichtung zur Verarbeitung der hinsichtlich des zeitlichen Verlaufs der nasalen bzw. der oralen Atmung indikativen Atemstromsignale, wobei die Datenverarbeitungseinrichtung derart konfiguriert ist, dass diese eine Speicherung von hinsichtlich des zeitlichen Verlaufs der Atemstromsignale indikativen Daten veranlasst.
Abstract:
The present invention relates to device, system and method for detecting a cardiac and/or respiratory disease of a subject. The proposed device comprises a sound input (20) for obtaining a sound signal representing sounds generated by the subject's body; a motion input (21) for obtaining a motion signal representing motions generated by the subject's body; and a processor (22) for processing the obtained sound signal and motion signal. This processing includes identifying inhalation and/or exhalation periods of the subject based on the motion signal, detecting abnormal lung sounds during inhalation and/or exhalation periods based on the sound signal, determining abnormal lung sound characteristics of the detected abnormal lung sounds, determining breathing characteristics of the subject's breathing based on the sound signal, determining the phase of the abnormal lung sounds in the inhalation-exhalation cycle, and detecting a cardiac and/or respiratory disease of the subject based on the determined abnormal lung sound characteristics, the determined breathing characteristics and the determined phase of the abnormal lung sounds in the inhalation-exhalation cycle.
Abstract:
The invention relates to a device (1) for monitoring the respiration of a user, said device comprising: - a textile support (2) with a tubular part (21) formed by knitting a largely electrically insulating ground thread, the tubular part (21) being suitable for covering the chest of the user, - at least one respiration sensor (3, 4) formed by knitting a detection thread (17), the detection thread (17) comprising an inner core of electrically insulating material and an outer sheath surrounding the inner core, the outer sheath being formed of electrically conductive material, in which the respiration sensor (3, 4) forms a conductive band (31, 41) having a first end (311, 411) and a second end (312, 412) which are positioned at a distance from each other, the ends being suitable for connection to an appliance for measuring the electrical resistance of the conductive band (31, 41).
Abstract:
A multi-sensor wireless abdominal monitoring system comprising a low-profile belt that fits around the abdomen and is embedded with specialized wireless sensors. The system is configured to continuously monitor a range of gastrointestinal and abdominal wall functions. The system wirelessly transmits data to an external device, such as a smartphone or computer for storage and download to a central server. The acquired data may be monitored remotely through specialized software that generates clinically interpretable information presented through a graphical user interface. The device provides data that are immediately actionable for a wide range of inpatients and outpatients with high prevalence disorders in varied clinical settings.
Abstract:
Systems and methods of identifying medical disorders in one or more subjects are disclosed herein. In one embodiment, sound is transmitted toward a subject and at least a portion of the sound reflected by the subject and is acquired as echo data. The acquired echo data is used to generate a motion waveform having a plurality of peaks detected therein. At feast a portion of the plurality of peaks may be indicative of movement of the subject. One or more medical disorders in the subject can be identified based on, for example, time durations and/or amplitude changes between peaks detected in the motion waveform.
Abstract:
A sweat and heart rate determination system includes a transmitter (1) configured to transmit a radio wave to a human body; a receiver (2) configured to receive the reflection wave of the radio wave transmitted by the transmitter (1); a heart rate determination part (34,234) configured to determine a heart rate based on a result of a frequency analysis for the reflection wave received by the receiver (2), a sweat determination part (44, 244) configured to determine a sweating state of the human body based on a strength of the reflection wave received by the receiver (2); and an output part 48, 248) configured to output information related to the heart rate determined by the heart rate determination part, and information related to the sweating state determined by the sweat determination part (44, 244).
