Abstract

A uterine activity analysis apparatus, comprising a rendering device at least one controller coupled to the rendering device, and configured to acquire a uterine activity signal (UAS) corresponding to uterine activity of a patient; determine uterine activity information based upon the acquired UAS and render, on the rendering device, content based at least in part including UAS upon the determined uterine activity information. The controller may compare the determined uterine activity information with threshold uterine activity information and provide clinical decision support (CDS) based upon the decision. Furthermore, the controller may render a breathing guide to illustrate a preferred breathing pattern, when the start of a contraction is detected.

First claim

1 . A uterine activity analysis apparatus, comprising:
a rendering device; and at least one controller coupled to the rendering device and configured to:
acquire a uterine activity signal corresponding to uterine activity of a patient;
determine uterine activity information based upon the acquired UAS, said uterine activity information comprising information related to at least one parameter of the acquired UAS being indicative of a contraction; and
render, on the rendering device, content based at least in part upon the determined uterine activity information.

2 . The apparatus of claim 1 , wherein the at least one controller is further configured to form the content in accordance with a selected uterine activity representation theme.

3 . The apparatus of claim 1 , wherein the at least one controller is further configured to compare the determined uterine activity information with threshold uterine activity information and provide clinical decision support based upon the decision.

4 . (canceled)

5 . The apparatus of claim 1 , wherein the at least one controller is configured to render a menu including a plurality of uterine activity representation themes for selection by a user.

6 . The apparatus of claim 1 , wherein the at least one controller is configured to render a breathing guide to illustrate a preferred breathing pattern, when the start of a contraction is detected.

7 . A method of rendering content related to uterine activity of a patient, the method performed by at least one controller of the imaging system and comprising acts of:
acquiring a uterine activity signal corresponding to uterine activity of a patient; determining uterine activity information based upon the acquired UAS, said uterine activity information comprising information related to at least one parameter of the acquired UAS being indicative of a contraction; and rendering, on a rendering device, content based at least in part upon the determined uterine activity information.

8 . The method of claim 7 , further comprising an act of forming the content further in accordance with a selected uterine activity representation theme.

9 . The method of claim 7 , further comprising an act of comparing the determined uterine activity information with threshold uterine activity information and provide clinical decision support based upon the decision.

10 . (canceled)

11 . The method of claim 7 , further comprising an act of rendering a menu including a plurality of uterine activity representation themes for selection by a user.

12 . The method of claim 7 , further comprising an act of rendering a breathing guide to illustrate a preferred breathing pattern, when the start of a contraction is detected.

13 . A computer program stored on a computer readable non-transitory memory medium, the computer program configured to carry out a method as defined in claims 6 - 10 .

14 - 19 . (canceled)

20 . The apparatus of claim 5 , wherein the selection by the user is performed either online or offline.

21 . The apparatus of claim 1 , wherein the content is annotated with information pertaining to the corresponding contractions and events indicating a time at which the corresponding contractions occurred, the duration and/or intensity.

22 . (canceled)

23 . The method of claim 7 , wherein the content is annotated with information pertaining to the corresponding contractions and events indicating a time at which the corresponding contractions occurred, the duration and/or intensity.

24 - 25 . (canceled)

26 . The computer program of claim 13 , further comprising nonlinear filtering to eliminate and/or reduce large spikes in the raw uterine activity signal.
