Abstract
An aspect of the invention described herein includes a method for a digestion diagnosis of a subject. The method includes obtaining electrogastrogram (EGG), bowel sound and NIRS signals from one or more sensors positioned about an abdominal region of a subject, removing artifacts from the signals to obtain conditioned signal data, and determining a digestion condition or feeding readiness of the subject based at least in part on the conditioned signal data.
Claims19
A method for diagnosing a digestion condition of a subject, the method comprising:
- obtaining electrogastrogram (EGG), bowel sound, and Near Infrared Spectroscopy (NIRS) signals from an EGG sensor, acoustic sensor and NIRS sensor, respectively, positioned about an abdominal region of a subject;
- removing artifacts from the signals to obtain conditioned signal data;
- and
- determining a digestion condition of the subject based at least in part upon the conditioned signal data, wherein determining the digestion condition of the subject comprises identifying an abnormal digestion condition or the location or severity thereof.
A system for diagnosis of a digestion condition or feeding readiness of a subject, or a combination thereof, the system comprising:
- a signal recording module configured to acquire GI signals from one or more sensors positioned about an abdominal region of a subject, wherein the GI signals comprise electrogastrogram (EGG), bowel sound, and Near Infrared Spectroscopy (NIRS) signals from an EGG sensor, acoustic sensor and NIRS sensor, respectively;
- a signal conditioning module configured to condition GI signal data from the one or more GI signals, wherein the signal conditioning module is configured to remove artifacts associated with movement of the subject from the GI signal data;
- a signal analysis module configured to determine at least one feature of a GI signal based at least in part on the conditioned GI signal data;
- and
- a condition classification module configured to determine a digestion condition of the subject based at least in part on the at least one feature of the GI signal;
- wherein the signal conditioning module is configured to remove artifacts associated with movement of the subject from the GI signal data and the condition classification module is configured to identify a location and/or a severity of an abnormal digestion condition.
A system for diagnosis of a digestion condition and/or a feeding readiness of a subject and to identify a subject at risk for disease, comprising:
- a computer comprising a computer processing module or modules to process (i) an EGG signal input;
- (ii) a bowel sound input and (iii) a NIRS input;
- a display to present data to an operator of the system;
- and
- an EGG probe, a bowel sound stethoscope and an NIRS probe in communication with said computer;
- and determining with the computer a digestion condition of the subject based at least in part upon the EGG, bowel sound and NIRS input data, wherein determining the digestion condition of the subject comprises identifying an abnormal digestion condition or the location or severity thereof.
