The present invention provides a method for swallow safety monitoring and a device thereof, which can monitor eating safety in real-time. By means of the real-time records of fundamental breath sound, the feeding safety for patients or weakness persons with dysphagia can be real-timely monitored and alarmed.

A system for monitoring dietary activity of a user includes a wearable device having at least one audio input unit configured to record an audio sample corresponding to audio from a user's neck. The system further includes a processor configured to execute programmed instructions stored in a memory to obtain an audio sample from the audio input unit of a wearable device, determine segmental feature values of a set of selected features from the audio sample by extracting short-term features in the set of selected features from the audio sample and determining the segmental feature values of the set of selected features from the extracted short-term features. The processor is further configured to, using a classifier, classify a dietary activity based on the determined segmental feature values of the audio sample and generate an output corresponding to the classified dietary activity.

An acoustic monitoring system has an acoustic front-end, a first signal path from the acoustic front-end directly to an audio transducer and a second signal path from the acoustic front-end to an acoustic data processor via an analog-to-digital converter. The acoustic front-end receives an acoustic sensor signal responsive to body sounds in a person. The audio transducer provides continuous audio of the body sounds. The acoustic data processor provides audio of the body sounds upon user demand.

Apparatuses for detecting swallowing disorders and methods for using same are provided. In a general embodiment, the apparatuses include a disposable sensor base and a sensor that is received by the disposable sensor base. The sensor base includes a sensor interface having a predetermined cut-away shape and a directionally-keyed mating surface. The sensor includes a handle portion having a shape that corresponds to the predetermined shape of the sensor interface, a support portion configured to be received by the directionally-keyed mating surface when the sensor is inserted into the sensor interface, and electronics configured to collect data sensed by the sensor. The apparatuses of the present disclosure can be attached to a patient's neck to detect and/or diagnose swallowing disorders during a swallowing test.

Predicting gastrointestinal impairment may involve obtaining intestinal sounds of a patient to generate audio data, identifying predefined spectral events in the audio data that are predictive of subsequent gastrointestinal impairment, the spectral events being defined by predefined parameters, and predicting the likelihood of subsequent gastrointestinal impairment relative to the identified spectral events.

A method to measure sound-producing behaviors of a subject with a power- and bandwidth-limited electronic device that includes a processor includes measuring, by a microphone communicatively coupled to the processor, sound in a vicinity of the subject to generate an audio data signal that represents the sound. The method also includes measuring, by at least one second sensor communicatively coupled to the processor, at least one parameter other than sound to generate at least a second data signal that represents the at least one parameter other than sound. The method also includes detecting one or more sound-producing behaviors of the subject based on: both the audio data signal and the second data signal; or information derived from both the audio data signal and the second data signal.

A method for evaluating a gastrointestinal tract may include receiving an electrical signal that includes data pertaining to motility in the gastrointestinal tract of a patient and analyzing one or more characteristics of the electrical signal relative to one or more respective thresholds indicative of an occurrence or an imminence of a condition of the gastrointestinal tract.

Devices and methods for predicting risk and likelihood of post-operative gastrointestinal impairment based on regression analysis of multiple spectral events related to intestinal sounds, with decreased or eliminated falsely elevated values of those events due to ambient noise.

An intestinal activity regulation device includes a regulator that performs a regulation process of regulating intestinal activity of a target person based on the state of the intestinal activity detected by a detector that detects the state of the intestinal activity of the target person.
