MESURE DES VARIATIONS PONDERALESMEASUREMENT OF WEIGHT VARIATIONS
DE SEGMENTS CORPORELSBODY SEGMENTS
La présente invention concerne une table de pesée segmentée d'un objet. Elle concerne également un procédé de mesure des variations pondérales de segments corporels.The present invention relates to a segmented weighing table for an object. It also relates to a method for measuring the weight variations of body segments.
L'invention trouve une application particulièrement avantageuse, mais non exclusive, dans les domaines de la physiologie humaine et de la médecine.The invention finds a particularly advantageous, but not exclusive, application in the fields of human physiology and medicine.
C'est notamment, mais non exclusivement, dans le but d'apporter une contribution technique à l'étude des déplacements liquidiens, sang, plasma ou eau, entre différentes parties du corps et entre les différents compartiments liquidiens, que l'invention propose une table de pesée segmentée d'un objet, remarquable en ce qu'elle est constituée d'une pluralité de moyens élémentaires de pesée définissant, chacun, un segment dudit objet, chaque moyen élémentaire de pesée étant apte à fournir un signal analogique élémentaire, représentatif du poids exercé par le segment d'objet correspondant.It is in particular, but not exclusively, with the aim of making a technical contribution to the study of fluid movements, blood, plasma or water, between different parts of the body and between the different fluid compartments, that the invention proposes a segmented weighing table of an object, remarkable in that it consists of a plurality of elementary weighing means, each defining a segment of said object, each elementary weighing means being capable of supplying an elementary, representative analog signal of the weight exerted by the corresponding object segment.
Ainsi, par la mise en oeuvre d'un procédé de mesure à tout instant des variations pondérales de segments corporels consistant à placer un sujet sur la table de pesée segmentée conforme à l'invention et à enregistrer les variations des signaux analogiques élémentaires fournis par chacun desdits moyens élémentaires de pesée, il est possible de mettre en évidence et de mesurer des transferts de liquides physiologiques d'un segment corporel à un autre par les variations pondérales qui en résultent, lesquelles sont détectées par le moyen élémentaire de pesée sur lequel repose chacun des segments concernés. De manière à pouvoir adapter la table de pesée segmentée, objet de l'invention, à la taille du sujet, notamment les enfants, mais aussi selon le choix de l'expérimentateur et la confrontation des résultats obtenus, il est prévu que lesdits moyens élémentaires de pesée sont séparément déplaçables le long d'une même direction longitudinale.Thus, by implementing a method of measuring at any time the weight variations of body segments consisting in placing a subject on the segmented weighing table according to the invention and in recording the variations of the elementary analog signals supplied by each of said elementary weighing means, it is possible to highlight and measure transfers of physiological liquids from one body segment to another by the resulting weight variations, which are detected by the elementary weighing means on which each one is based of the segments concerned. In order to be able to adapt the segmented weighing table, object of the invention, to the size of the subject, in particular children, but also according to the choice of the experimenter and comparison of the results obtained, provision is made for said elementary weighing means to be separately movable along the same longitudinal direction.
Les mesures des déplacements liquidiens mentionnés plus haut peuvent être effectuées de façon statique ou dynamique.The liquid displacement measurements mentioned above can be performed statically or dynamically.
Dans le cas de pesées statiques, la répétition des mesures à quelques heures, jours, semaines ou plus, d'intervalle chez un même sujet peut renseigner sur les variations absolues et relatives de la masse de chaque segment corporel. Il convient ensuite d'utiliser des techniques appropriées : scannographies X, résonance magnétique nucléaire, eau tritiée et autres marqueurs des compartiments liquidiens, pour préciser la part de chaque constituant dans les variations temporelles observées : os, muscles, liquides. De même, la répétition des mesures effectuées strictement dans les mêmes conditions peut être comparée entre différents individus classés par sexe, âge, activités physiques pratiquées, habitudes alimentaires, pourcentage de matière grasse, etc.In the case of static weighings, the repetition of the measurements at a few hours, days, weeks or more, intervals for the same subject can provide information on the absolute and relative variations in the mass of each body segment. It is then necessary to use appropriate techniques: X-ray scans, nuclear magnetic resonance, tritiated water and other markers of the liquid compartments, to specify the part of each constituent in the temporal variations observed: bones, muscles, liquids. Similarly, the repetition of measurements carried out strictly under the same conditions can be compared between different individuals classified by sex, age, physical activities practiced, eating habits, percentage of fat, etc.
Lors de pesées dynamiques, les variations pondérales sont mesurées pendant que des échanges liquidiens entre les différents segments corporels sont en train de se produire. Ces échanges peuvent être provoqués par des modifications posturales des sujets, dont le meilleur exemple est le passage de la position debout à la position couchée. Les pesées doivent être effectuées le plus précocement possible après la variation posturale et permettent de suivre l'évolution des transferts liquidiens entre les segments corporels concernés lors de cette manoeuvre. Ces échanges peuvent aussi être provoqués en interrompant plus ou moins complètement le courant circulatoire de manière à faire varier le contenu sanguin des vaisseaux capacitifs des membres inférieurs ou supérieurs en exerçant une pression externe : pantalon anti-choc, attelles gonflables ou garrottage veineux de la racine des membres. La variation de masse dans les différents segments corporels traduit alors le déplacement de la masse liquidienne : le sang à l'échelle de la seconde, les liquides interstitiels avec une constante de temps de l'ordre de la minute. Après levée de la compression externe, la table de pesée segmentée de l'invention permet d'analyser le profil temporel de remplissage des zones préalablement comprimées.During dynamic weighings, the variations in weight are measured while fluid exchanges between the different body segments are taking place. These exchanges can be caused by postural modifications of the subjects, the best example of which is the transition from the standing position to the lying position. The weighings must be carried out as early as possible after the postural variation and make it possible to follow the evolution of the liquid transfers between the bodily segments concerned during this maneuver. These exchanges can also be caused by interrupting more or less completely the circulatory current so as to vary the blood content of the capacitive vessels of the lower or upper limbs by exerting external pressure: shockproof pants, inflatable splints or venous root garrot members. The variation in mass in the different body segments then translates the displacement of the liquid mass: the blood on the scale of the second, the interstitial liquids with a time constant of the order of a minute. After lifting of the external compression, the table segmented weighing of the invention makes it possible to analyze the time profile of filling of the previously compressed zones.
Les déplacements liquidiens ainsi mesurés par pesée segmentée peuvent être interprétés en fonction d'autres variables hémodynamiques, telles que débit cardiaque, résistances vasculaires systémiques, etc, mesurées au moyen d'autres appareillages : dopplerographie, impédancemétrie, etc.The fluid displacements thus measured by segmented weighing can be interpreted as a function of other hemodynamic variables, such as cardiac output, systemic vascular resistances, etc., measured by means of other devices: dopplerography, impedancemetry, etc.
De même, les variations de fréquence cardiaque, de pression artérielle, de concentrations plasmatiques des médiateurs et des hormones qui contribuent à l'ajustement hémodynamique, comparées aux données obtenues par les mesures de pesée segmentée sur la répartition liquidienne dans l'organisme, peuvent fournir des indices sur les modifications des réglages des récepteurs, baro-récepteurs, et des mécanismes nerveux et endocriniens d'ajustement hémodynamique.Likewise, variations in heart rate, blood pressure, plasma concentrations of mediators and hormones that contribute to hemodynamic adjustment, compared to data obtained from segmented weighing measurements of fluid distribution in the body, can provide clues to changes in the settings of receptors, baro-receptors, and nervous and endocrine mechanisms of hemodynamic adjustment.
La description qui va suivre en regard des dessins annexés, donnés à titre d'exemples non limitatifs, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée.The description which follows with reference to the appended drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be implemented.
La figure 1 est un schéma d'un dispositif de pesée segmentée d'un objet, conforme à l'invention.Figure 1 is a diagram of a segmented weighing device of an object, according to the invention.
Les figures 2a à 2c sont des enregistrements simultanés de pesée segmentée statique concernant respectivement les épaules, le bassin et les jambes d'un sujet.Figures 2a to 2c are simultaneous recordings of static segmented weighing concerning the shoulders, pelvis and legs of a subject, respectively.
Les figures 3 a à 3f sont des enregistrements simultanés de pesée segmentée dynamique concernant respectivement la tête, les épaules, le bassin, les jambes, les pieds et le poids total d'un sujet. La figure 1 montre de manière schématique un dispositif de pesée segmentée d'un objet, ici un sujet 1, ledit dispositif comprenant une table 10 de pesée segmentée constituée d'une pluralité de cinq moyens élémentaires Ilι,ll2,ll3,ll4 et I I5 de pesée définissant, chacun, un segment ** 1»**2'^3'**4 et **5 dudit sujet 1. Dans l'exemple illustré à la figure 1, ces différents segments corporels correspondent respectivement aux pieds, aux jambes, au bassin, au buste et à la tête dudit sujet. Comme on peut le voir sur la figure 1, chaque moyen élémentaire 111,112, 113,114 et I I5 de pesée comporte un plateau 12j, 122, 123, 124 et 125 destiné à supporter le segment 1 j, I2, 13, 14 et I5 du sujet correspondant. Lesdits plateaux sont en appui respectif sur des capteurs 131,132,133,134 et 135 de pesée, aptes à fournir un signal analogique élémentaire S|,S2,S3,S4 et S5, représentatif du poids exercé par le segment de sujet correspondant. L'ensemble formé par chaque plateau et le capteur de pesée associé est porté par une platine 14j, 142, 143,144 et 14^.FIGS. 3 a to 3f are simultaneous recordings of dynamic segmented weighing relating respectively to the head, the shoulders, the pelvis, the legs, the feet and the total weight of a subject. Figure 1 shows schematically a segmented weighing device of an object, here a subject 1, said device comprising a segmented weighing table 10 consisting of a plurality of five elementary means Ilι, ll2, ll3, ll4 and I I5 weighing, each defining a segment ** 1 "** 2 '^ 3' ** 4 and ** 5 of said subject 1. In the example illustrated in FIG. 1, these different body segments correspond respectively to the feet, to the legs, pelvis, bust and head of said subject. As can be seen in FIG. 1, each elementary means 111, 112, 113, 114 and I I5 of weighing comprises a plate 12 j , 12 2 , 123, 124 and 125 intended to support the segment 1 j , I2, 13, 14 and I5 of the corresponding subject. Said plates are supported respectively on weighing sensors 131, 132, 133, 134 and 135, capable of supplying a basic analog signal S | , S2, S3, S4 and S5, representative of the weight exerted by the corresponding subject segment. The assembly formed by each plate and the associated weighing sensor is carried by a plate 14 j , 142, 143, 144 and 14 ^.
De manière à pouvoir rendre déplaçables séparément les moyens élémentaires 111,112-.113,1 14 et I I5 dans une même direction longitudinale et donc à pouvoir choisir et ajuster leurs écarts respectifs, les platines 14|, 142,143,144 et 14^ sont montées coulissantes sur des rails longitudinaux 20. Bien entendu, chaque platine peut être maintenue en position longitudinale à l'aide de moyens de blocage, non représentés sur la figure 1. Les capteurs 13 j, 132,133, 134 et 13^ de pesée peuvent être les capteurs type AG commercialisés par la Société SCAIME qui présentent une très bonne sensibilité puisqu'ils permettent de déceler des variations de l'ordre de 10g pour des masses de 70 à 80kg.So as to be able to make the elementary means 111,112-.113,1 14 and I I5 separately displaceable in the same longitudinal direction and therefore to be able to choose and adjust their respective distances, the plates 14 | , 142,143,144 and 14 ^ are slidably mounted on longitudinal rails 20. Of course, each plate can be maintained in the longitudinal position using locking means, not shown in Figure 1. The sensors 13 j , 132,133, 134 and 13 ^ of weighing can be the AG type sensors sold by the company SCAIME which have very good sensitivity since they allow variations of the order of 10g to be detected for masses of 70 to 80kg.
Afin d'éliminer les risques de surcharge ou de mal-position susceptibles de créer des efforts inacceptables pour lesdits capteurs de pesée, il est prévu sur les capteurs des butées fixes de protection, non représentées.In order to eliminate the risks of overload or improper position likely to create unacceptable forces for said weighing sensors, there are provided on the sensors fixed protective stops, not shown.
Les signaux analogiques élémentaires sj, S2, 83,5 et S5 sont ensuite dirigés vers une unité 30 de traitement comprenant un boîtier 31 dans lequel lesdits signaux analogiques élémentaires sont échantillonnés à une fréquence choisie (10Hz par exemple), et convertis en signaux numériques. Un afficheur 310 permet de visualiser le poids partiel mesuré par chaque capteur élémentaire et de régler le zéro correspondant à l'aide des potentiomètresThe elementary analog signals s j , S2, 83.5 and S5 are then sent to a processing unit 30 comprising a box 31 in which said elementary analog signals are sampled at a chosen frequency (10 Hz for example), and converted into digital signals . A display 310 enables the partial weight measured by each elementary sensor to be displayed and the corresponding zero to be adjusted using the potentiometers
Les signaux numérisés sont transmis à des moyens informatiques 32, tels qu'un microordinateur du type PC, où ils sont stockés en mémoire et soumis à un traitement mathématique afin de neutraliser les phénomènes aléatoires, très nombreux dans ce genre d'expériences, par la division d'une mesure donnée en une pluralité de mesures très proches dans le temps (0,1s ou moins) et par le traitement de ces données multiples suivant un schéma approprié (moyennes, moyennes glissantes, maximums, minimums, etc) pour fournir des graphiques comme ceux montrés aux figures 2a à 2c et 3a à 3f.The digitized signals are transmitted to computer means 32, such as a microcomputer of the PC type, where they are stored in memory and subjected to a mathematical processing in order to neutralize the random phenomena, very numerous in this kind of experiments, by the division of a measurement given in a plurality of measurements very close in time (0.1s or less) and by processing this multiple data according to an appropriate diagram (averages, sliding averages, maximums, minimums, etc.) to provide graphs like those shown in Figures 2a to 2c and 3a to 3f.
Les figures 2a à 2c donnent les résultats de pesée statique segmentée, au sens défini plus haut, effectuées respectivement au niveau des épaules, des bassins et des jambes d'un sujet. Ces graphiques ont été enregistrés en continu pendant 20 secondes au rythme d'une mesure tous les dixièmes de seconde, soit au total 200 points de mesure.FIGS. 2a to 2c give the results of segmented static weighing, in the sense defined above, carried out respectively at the level of the shoulders, the basins and the legs of a subject. These graphs were recorded continuously for 20 seconds at the rate of one measurement every tenth of a second, for a total of 200 measurement points.
On voit apparaître des oscillations de grande amplitude, constantes d'un segment à l'autre et dont la période complète dure environ 3 secondes. En première analyse, ces oscillations sont vraisemblablement dues à la ventilation pulmonaire. Les figures 3a à 3f donnent les résultats de pesée dynamique segmentée, au sens défini plus haut, effectuée respectivement au niveau de la tête, des épaules, du bassin, des jambes, des pieds ainsi que le poids total, durant 13 minutes de decubitus. Ces graphiques ont été enregistrés en prenant la moyenne glissante des moyennes des mesures faites pendant 4 secondes à la fréquence d'échantillonnage de 10Hz. Ils montrent bien les transferts liquidiens qui se produisent chez un individu qui passe de la position debout à la position couchée. We see the appearance of large amplitude oscillations, constant from one segment to another and whose full period lasts about 3 seconds. At first analysis, these oscillations are probably due to pulmonary ventilation. FIGS. 3a to 3f give the results of segmented dynamic weighing, in the sense defined above, carried out respectively at the level of the head, the shoulders, the pelvis, the legs, the feet as well as the total weight, during 13 minutes of decubitus. These graphs were recorded by taking the moving average of the averages of the measurements made for 4 seconds at the sampling frequency of 10 Hz. They clearly show the fluid transfers that occur in an individual who goes from standing to lying down.
