Processing apparatus and method for processing electromyogram signals related to respiratory activity

摘要

The present invention relates to the field of medical technology, and in particular, determines respiratory activity in patients with chronic obstructive pulmonary disease (COPD) based on surface electromyogram measurements obtained from intercostal muscles on a subject's chest. It has something to do with it. A processing device for processing an electromyographic signal indicative of the activity of a target muscle in a human or animal body related to the measurement of respiratory effort during at least one other muscle activity is shown. The processing apparatus comprises: a first interface for receiving a first electromyogram signal obtained from the target muscle and the other muscle at a first location on the body; a second location on the body And a second interface for receiving a second electromyogram signal obtained from the other muscle, and a similarity signal based on the first electromyogram signal and the second electromyogram signal An analysis unit for determining a respiratory phase if the similarity signal obtained from the first and second electromyogram signals is lower than a first predetermined threshold value. And / or if the similarity signal obtained from the first and second electromyogram signals exceeds a second predetermined threshold, the respiratory phase is determined to be the expiratory phase Configured to do.
