A method and apparatus for implementing a user interface for displaying uterine contraction information is provided. The contraction signal is processed to derive a sequence of contraction persistence indices. Each contraction persistence index in the sequence is associated to a portion of the contraction signal and conveys whether there is an excess in the rate of contraction in the associated portion of the contraction signal. If there is an excess in the rate of contraction in the associated portion of the contraction signal, the contraction persistence index conveys whether this excess is part of a sustained pattern of excess in the rate of contractions or whether the excess is likely to be transient. The sequence of contraction persistence indices is displayed to a user. Optionally, the graphical user interface is adapted for selectively causing an alarm event based at least in part on the sequence of contractility persistence indices. The method and apparatus may be implemented on any suitable computing platform such as for example desktop computers, laptop computers and personal digital assistants (PDAs).

L'invention concerne un procédé et un appareil destinés à mettre en uvre une interface d'utilisateur servant à afficher des informations sur les contractions utérines. Le signal de contraction est traité pour en tirer une séquence d'indices de persistance des contractions. Chaque indice de persistance des contractions de la séquence est associé à une partie du signal de contraction et indique si le taux de contraction est excessif dans la partie en question du signal de contraction. Si c'est le cas, l'indice de persistance des contractions indique si cet excès fait partie d'un schéma persistant de taux de contraction excessif ou si l'excès est plus probablement transitoire. La séquence d'indices de persistance des contractions est affichée au profit d'un utilisateur. Éventuellement, l'interface graphique d'utilisateur est prévue pour déclencher sélectivement un évènement d'alarme basé au moins en partie sur la séquence d'indices de persistance des contractions. Le procédé et l'appareil peuvent être mis en uvre sur une quelconque plateforme informatique adéquate, comme par exemple des ordinateurs de bureau, des ordinateurs portables et des assistants numériques personnels (PDA).
