The method allows controlling the quality of an initial RR series made up of a plurality of (RRi) samples which are respectively a function of time intervals (&#x3b4;ti) which separate two successive heartbeats. During this method, one resamples the RR series so as to obtain a resampled RR series, and one automatically controls the quality of the RR series by automatically calculating at least the mathematical norm value (NORME), in a sliding window, of the resampled RR series, said mathematical norm value being given by the following formula: where N is the number of RRi samples in said window.

Method and device for automatic quality control of an RR series obtained from a cardiac signal

A device allowing the creation of an alimentary bolus flow between two stomas, including means forming a pump; first/second sealed connection means capable of connecting the suction opening to an upstream/downstream stoma located on the abdominal wall of a patient; and first and/or second anti-reflux means. The first and/or second anti-reflux means includes a cavity into which the alimentary bolus passes, an inflatable balloon mounted in the cavity and means for inflating the balloon, that make it possible to modify the inflation of the latter, and the balloon is shaped to shift from an open position in which the balloon is partially inflated and has a neck allowing the passage of the alimentary bolus, to a closed position in which the balloon is more inflated than in the open position and in which the balloon is in contact with the wall of the cavity and the neck is sealed as a result of the portion of the wall of the balloon defining the neck being compressed against itself, at least over a portion of the height of the neck.

Method and device for automatically checking the quality of an RR series obtained from a cardiac signal

A device enabling food bolus flow between two stomas, said device having a pump forming means (), said pump forming means () having an entry opening and an exit opening and being suitable for sucking food bolus through said entry opening and releasing it through said exit opening. The device further includes: &#x2014;first watertight connection means () suitable for connecting said entry opening to a upstream stoma (S) located on a patient's abdominal wall; &#x2014;second watertight connection means () suitable for connecting said exit opening to a downstream stoma (S), located on said patient's abdominal wall; said pump forming means being able to be activated by a user and suitable for being mounted on a patient's body, particularly on said patient's abdomen, in such a manner that once said device is mounted onto said patient's abdomen, food bolus flow can circulate from said upstream stoma (S) to said downstream stoma (S) outside of said patient's abdomen.

The inventive method for processing an RR series comprises a plurality of (RR) samples representing time intervals (dti) between two successive heart beats or the inverse (1/dti) of said time intervals consists in selecting (N) (RRi) samples in a main time window having a predetermined length (n), in cutting said main window into (m) subwindows (F), in calculating an intermediate parameter (A) for each subwindow (F) on the basis of the (RRi) samples contained in the subwindow (F) and in calculating a final parameter as a function of the intermediate parameters (A). The invention is used for analysing a cardiac rhythm variability, in particular for assessing a patient's pain or stress.

The RR series, comprising a number of samples respectively defining the time interval between two successive heartbeats, is filtered by means of a digital band-pass filter (F), having a given band-pass [fc; f'c] and preferably by means of a recursive elective filter (RII). A variability index (I), is calculated which is a function of the instantaneous amplitude [vs(n)] of the discrete signal (S) coming from said band-pass filter. The variability index (I) is preferably a function of and particularly equal to the effective value of the discrete signal (S) from the band-pass filter.
