Abstract

The appts. measures arterial pressure by an external method. It consists of a device for measuring the instantaneous velocity of the blood in an artery and the mean blood circulation velocity using the Doppler effect. The device is fixed close to an artery in a region exempt from deformation due to articulation movements such as the temporal artery. A compact portable magnetic recorder registers signals from the measuring device over a long period. A correlation is established between the velocity of the blood and the arterial pressure of the subject using a computer which supplies a first or second degree relation corresponding to the best approximation of the correlation based on a number of measurements taken under various conditions to which the subject is submitted.

Description

L'invention se rapporte à un procédé de mesure de la pression artérielle par voie externe. The invention relates to a method for measuring blood pressure externally.

La mesure de la pression artérielle s1 effectue ordinairement au moyen d'un tensiomètre suivant la méthode de Vaquez. Cette méthode, facile à mettre en oeuvre, ne permet pas d'effectuer une mesure continue des variations de la pression artérielle. Une telle mesure est possible par irfroduction dans une artère d'une aiguille reliée à un manomètre convenable; mais il est évident qu'on ne peut recourir qu'exceptionnellement à pareille opération, qui ne saurait d'ailleurs permettre des mesures de longue durée. The measurement of the arterial pressure is usually carried out by means of a tensiometer according to the method of Vaquez. This easy-to-use method does not allow continuous measurement of variations in blood pressure. Such a measurement is possible by irradiation into an artery of a needle connected to a suitable manometer; but it is obvious that such an operation can only be used exceptionally, which cannot, moreover, allow long-term measures.

Or, il a été constaté que la pression artérielle était reliée de façon simple à la vitesse de circulation du sang; la relation, qui est généralement linéaire, parfois du second degré, dépend de chaque individu. However, it was found that the arterial pressure was linked in a simple way to the speed of circulation of the blood; the relation, which is generally linear, sometimes of the second degree, depends on each individual.

En conséquence, l'invention a pour objet un procédé de mesure aisé à mettre en oeuvre, même sur une longue durée, et non traumatisant pour le sujet. Ce procédé consiste à établir préalablement, pour le sujet soumis à la mesure, la relation qui existe entre la pression.  Consequently, the subject of the invention is a measurement method which is easy to implement, even over a long period, and which is not traumatic for the subject. This process consists in establishing beforehand, for the subject subjected to the measurement, the relation which exists between the pressure.

artérielle et la vitesse de circulation du sang dans une artère déterminée en mesurant simultanément ces deux paramètres sur le sujet au repos et à différents niveaux d'effort musculaire, la pression étant mesurée suivant une méthode classique telle que la méthode de Vaquez et la vitesse au moyen d'un capteur à effet Doppler couplé à l'artère précitée, puis à mesurer de manière continue, pendant toute période de temps jugée con~enable, la vitesse circulatoire du sujet à l'aide dudit capteur, pour en déduire ensuite, à l'aide de la relation préalablement établie, la pression artérielle et ses variations pendant ladite période de temps.arterial pressure and the speed of blood circulation in a given artery by simultaneously measuring these two parameters on the subject at rest and at different levels of muscular effort, the pressure being measured according to a conventional method such as the Vaquez method and the speed at means of a Doppler effect sensor coupled to the aforementioned artery, then to measure continuously, for any period of time deemed to be con ~ enable, the circulatory speed of the subject using said sensor, to then deduce therefrom, using the previously established relationship, blood pressure and its variations during said period of time.

L'artère servant à faire la mesure de la vitesse circulatoire doit être facile d'accès, proche du coeur et située dans une région exempte de déformations dues à des mouvements d'articulations. Une artère répondant à ces conditions est l'artère temporale. The artery used to measure the circulatory speed must be easy to access, close to the heart and located in a region free of deformations due to movements of joints. An artery meeting these conditions is the temporal artery.

La vitesse circulatoire mesurée est de
préférence enregistrée durant la période de temps précitée,
l'enregistrement obtenu pouvant être dépouillé ultérieure
ment en l'absence du sujet. Avantageusement, on enregistre
simultanément la vitesse circulatoire instantanée et la
valeur moyenne de cette vitesse par rapport au temps.
The circulatory speed measured is
preference recorded during the aforementioned period of time,
the recording obtained can be stripped later
in the absence of the subject. Advantageously, one records
simultaneously the instantaneous circulatory speed and the
average value of this speed compared to time.

Dans le cas de mesures de longue durée, il
convient d'effectuer l'enregistrement au moyen d'un
appareil autonome porté par le sujet.
In the case of long-term measurements,
agrees to perform the registration by means of a
autonomous device carried by the subject.

La description qui va suivre, en référence à l'exemple indiqué à titre non limitatif, permettra de bien
comprendre comment l'invention peut être-mise en pratique.
The following description, with reference to the example given without limitation, will clearly
understand how the invention can be put into practice.

On utilise un dispositif de mesure à effet
Doppler dont le capteur émetteur-récepteur est placé sur
l'artère temporale du sujet et y est fixée au moyen de
bandes adhésives de façon qu'il reste immobile tout au
long des mesures. L'appareil fournit un signal traduisant
la vitesse instantanée du sang dans l'artère et un autre
signal représentant la vitesse moyenne de circulation
du sang. Ces signaux sont enregistrés sur bande magnétique
dans un appareil compact et portable, alimenté par batterie
et capable d'effectuer des enregistrements de longue durée
(par exemple 24 heures). Cet appareil est porté par le
sujet durant les mesures, ce qui ne lui cause qu'une
gêne minime.
We use an effect measurement device
Doppler with the transmitter-receiver sensor placed on
the temporal artery of the subject and is fixed there by means of
adhesive strips so that it remains stationary throughout
along the measures. The device provides a signal translating
the instantaneous speed of blood in the artery and another
signal representing the average speed of circulation
some blood. These signals are recorded on magnetic tape
in a compact and portable device, powered by battery
and capable of performing long-term recordings
(e.g. 24 hours). This device is worn by the
subject during the measurements, which causes him only one
minimal discomfort.

On effectue tout d'abord les opérations
d'étalonnage permettant d'établir la relation entre la
vitesse circulatoire et la pression sanguine pour le sujet
examiné. A cet effet, celui-ci est placé sur une bicyclette
ergométrique et il lui est demandé de fournir un travail
par paliers successifs. A chacun de ces paliers, qui
correspondent à des niveaux d'effort différents, on
enregistre la valeur de la vitesse circulatoire et on
mesure la pression artérielle par la méthode stéthacoustique
classique. Plus précisément, on relève d'abord la pression
de repos avec ses deux composantes systolique et diastolique,
puis des pressions artérielles d'effort (avec leurs deux
composantes), et enfin des pressions artérielles de
récupération. Ces mesures permettent de déterminer la relation vitesse-pression sanguine à l'aide d'un ordinateur qui fournit la relation du premier ou du second degré correspondant à la meilleure approximation entre tous les points de mesure.
We first perform the operations
calibration to establish the relationship between the
circulatory speed and blood pressure for the subject
examined. For this purpose, it is placed on a bicycle
ergometric and asked to provide work
in successive steps. At each of these levels, which
correspond to different levels of effort, we
records the value of the circulatory speed and
measures blood pressure by the stethacoustic method
classic. More precisely, we first note the pressure
rest with its two systolic and diastolic components,
then of the arterial pressures of effort (with their two
components), and finally blood pressure from
recovery. These measurements make it possible to determine the speed-blood pressure relationship using a computer which provides the first or second degree relationship corresponding to the best approximation between all the measurement points.

Cette phase d'étalonnage étant achevée, on procède à la mesure proprement dite, qui consiste à enregistrer la vitesse circulatoire du sujet pendant la période de temps désirée. La relation préalablement déterminée permet de déduire de l'enregistrement réalisé les variations de la pression artérielle du sujet tout au long de cette période de temps. Ces variations peuvent être traduites graphiquement sous la forme d'un histogramme.  This calibration phase having been completed, the actual measurement is carried out, which consists in recording the circulatory speed of the subject during the desired period of time. The previously determined relationship makes it possible to deduce from the recording carried out the variations in the subject's blood pressure throughout this period of time. These variations can be translated graphically as a histogram.
