Abstract
A method and apparatus for detecting a physiological signal and for providing indication of an event relating to the physiological signal. The apparatus including an input terminal for connection to a patient to acquire a physiological signal having at least one physiological event, an analysis module having a processor and software for operating the processor to determine an occurrence of the event and to generate a signal upon the occurrence of the event, and an indicator that receives the signal and provides to a user an indication of the event in response to the signal. The method including obtaining the physiological signal, determining the onset of the physiological event, and generating a signal in response to the onset of the physiological event.
Claims19
A medical device, comprising:
- an input terminal for connection to a patient to acquire a uterine activity signal comprising a uterine contraction;
- an analysis module comprising a processor and software for operating the processor to determine a change in incremental slope of the uterine activity signal, to determine an indication of an event relating to the uterine contraction based on the change in incremental slope, and to generate a signal upon the indication of the event;
- and
- an audible indicator that receives the signal and provides to a user an audible indication of the event in response to the signal, the audible indication of the event being perceptible by a user without requiring the user to view a visual display of the uterine activity signal.
A software program for indicating to a user the occurrence of a uterine contraction in a uterine activity signal obtained from a patient, the software indicating the uterine contraction by:
- obtaining the uterine activity signal;
- determining a change in incremental slope of the uterine activity signal;
- determining an occurrence of an event relating to the uterine contraction based on the change in incremental slope of the uterine activity signal;
- generating a signal upon the occurrence of the event;
- providing the signal to an audible indicator;
- and
- providing an audible indication of the occurrence of the event from the audible indicator to a user in response to the signal, the audible indication of the occurrence of the event being perceptible by the user without requiring the user to view a visual display of the uterine activity signal.
