Description

L'invention concerne un casque de caoutchouc du genre de ceux que les médecins utilisent pour en coiffer le cr - ne d'un patient afin d'y positionner des électrodes en vue de pratiquer un électro-encéphalogramme. The invention relates to a rubber helmet of the kind used by doctors to cover the skull of a patient in order to position electrodes therein for performing an electroencephalogram.

Un casque connu est réalisé à partir de fils élastiques, généralement en caoutchouc, que l'on croise deux à deux en constituant une sorte de résille. A chaque point de croisement, les duux fils élastiques considérés sont engagés dans les perçages d'une pièce de jonction, gén-érale- ment en matière plastique. Ensuite, le praticien engage sous certains fils élastiques, une ou plusieurs électrodes de recueil de potentiels qui se trouvent ainsi positionnées contre le cuir chevelu du patient. A known helmet is made from elastic threads, generally made of rubber, which are crossed in pairs, constituting a kind of mesh. At each crossing point, the two elastic threads considered are engaged in the holes of a junction piece, generally made of plastic. Then, the practitioner engages under certain elastic wires, one or more electrodes for collecting potentials which are thus positioned against the patient's scalp.

-Ce système connu présente plusieurs inconvénients - deux pièces sont nécessaires ; la pièce de jonction en
tre deux fils de caoutchouc n'est pas conductrice de
l'électricité - si le malade vient à bouger, la mesure peut s'en trouver
faussée par suite d'un manque de fermeté- d'une ou plusieurs
électrodes du dispositif.-This known system has several drawbacks - two pieces are necessary; the connecting piece in
two rubber threads do not conduct
electricity - if the patient moves, the measurement can be found
distorted due to a lack of firmness - one or more
device electrodes.

La présente invention a pour but d'éviter ces inconvénients. The present invention aims to avoid these drawbacks.

Pour cela, une pièce de jonction selon l'invention comporte deux perçages transversaux superposés orthogonaux entre eux, et elle est caractérisée en ce que, d'une part elle peut etre réalisée dans tous matériaux conducteurs de l'électricité (argent ou métaux), tandis que d'autre part son sommet peut posséder un tenon susceptible de recevoir le raccordement d'un fil électrique, alors que sa base est prévue pour assurer un bon contact électrique sur le cuir chevelu du patient. For this, a junction piece according to the invention comprises two transverse bores superposed orthogonal to each other, and it is characterized in that, on the one hand, it can be made of all electrically conductive materials (silver or metals), while on the other hand its top may have a tenon capable of receiving the connection of an electric wire, while its base is provided to ensure good electrical contact on the scalp of the patient.

Suivant une autre caractéristique de l'invention, le corps de la pièce est en une matière synthétique chargée de poudre métallique (caoutchouc conducteur; etc.). According to another characteristic of the invention, the body of the part is made of a synthetic material loaded with metallic powder (conductive rubber, etc.).

Suivant une autre caractéristique de l'invention, le corps de la pièce est de forme générale cylindrique, une gorge étant prévue éventuellement sur la périphérie du tenon pour faciliter l'ajecrochage d'une pièce de raccordement électrique(#ince, fiche ou autre).  According to another characteristic of the invention, the body of the part is of generally cylindrical shape, a groove possibly being provided on the periphery of the post to facilitate the attachment of an electrical connection part (#ince, plug or other) .

Suivant une autre caractéristique de l'invention, la base du corps est plane. According to another characteristic of the invention, the base of the body is planar.

Suivant une autre caractéristique de l'invention, la base du corps est concave. According to another characteristic of the invention, the base of the body is concave.

Suivant une autre caractéristique de l'invention, la base du corps est convexe. According to another characteristic of the invention, the base of the body is convex.

Suivant une autre caractéristique de l'invention, la partie inférieure du corps est percée d'un canal latéral oblique débouchant dans la partie inférieure de la base pour l'introduction d'une goutte d'un liquide favorisant la bonne qualité du contact électriqùe sur le cuir chevelu. According to another characteristic of the invention, the lower part of the body is pierced with an oblique lateral channel opening into the lower part of the base for the introduction of a drop of a liquid promoting the good quality of the electrical contact on scalp.

Le dessin annexé, donné à titre d'exemple non limitatif, permettra de mieux comprendre les caractéristiques de l'invention. The appended drawing, given by way of nonlimiting example, will allow a better understanding of the characteristics of the invention.

Figure 1 est une vue d'ensemble de la tête d'un patient coiffé d'un casque réalisé selon l'invention. Figure 1 is an overall view of the head of a patient wearing a helmet made according to the invention.

Figure 2 est une vue en perspective d'une pièce de jonction selon l'invention. Figure 2 is a perspective view of a junction piece according to the invention.

Figure 3 montre une autre variante équipée d'une pince de raccordement électrique. Figure 3 shows another variant equipped with an electrical connection clamp.

Figure 4 est une coupe diamétrale suivant IV-IV (figure 3). Figure 4 is a diametrical section along IV-IV (Figure 3).

Figure 5 est une coupe analogue d'une variante supplémentaire. Figure 5 is a similar section of an additional variant.

On a représenté sur les dessins le crâne 1 d'un patient coiffé à la manière connue d'un casque de caoutchouc pour la prise d'un électro-encéphalogramme. Ce casque est constitué par un entrecroisement de fils de caoutchouc 2 qui se croisent deux à deux. There is shown in the drawings the skull 1 of a patient wearing a rubber helmet in the known manner for taking an electroencephalogram. This helmet is constituted by an intertwining of rubber wires 2 which cross two by two.

A chaque point de croisement, l'invention prévoit une pièce de jonction 3 du type illustré plus en détail sur les figures 2 à 5. At each crossing point, the invention provides a junction piece 3 of the type illustrated in more detail in FIGS. 2 to 5.

La pièce 3 de la figure 2 possède un curps cylindrique terminé à son sommet par un tenon de raccordememt 4, et à sa base par un renflement 5 sous lequel est défini un fond bombé 6. Le corps de la pièce 3 est traversé par deux perçages transversaux 7 et 8, orthogonaux entre eux. Il est séparé du tenon de raccordement 4 par une gorge périphérique 9.  The part 3 of FIG. 2 has a cylindrical curp terminated at its top by a connecting pin 4, and at its base by a bulge 5 under which is defined a curved bottom 6. The body of the part 3 is crossed by two holes transverse 7 and 8, orthogonal to each other. It is separated from the connecting stud 4 by a peripheral groove 9.

La pièce 3 des figures 3 et 4 possède un corps entièrement cylindrique, y compris son tenon supérieur 10 qui peut recevoir une pièce de jonction 14. Le-fond 11 de la base est plat. The part 3 of FIGS. 3 and 4 has a completely cylindrical body, including its upper tenon 10 which can receive a junction piece 14. The bottom 11 of the base is flat.

Dans la variante de la figure 5, le fond 12 de la base est concave. De plus, s'ouvre latéralement dans le corps de la pièce 3 un canal oblique 13 débouchant dans la partie centrale du fond 12. In the variant of Figure 5, the bottom 12 of the base is concave. In addition, an oblique channel 13 opens laterally in the body of the part 3 opening into the central part of the bottom 12.

Le fonctionnement est le suivant
On dispose la pince crocodile 14 sur l'électrode. La pince crocodile 14 est rattaché à la pièce métallique au tenon supérieur.The operation is as follows
The crocodile clip 14 is placed on the electrode. The alligator clip 14 is attached to the metal piece on the upper lug.

Le casque s'applique sur la tête du patient de la manière suivante les fils reliant les pièces métalliques sont disposés sur le crâne du patient, les plaques de matière plastique en forme de demi-cercle seront placées sous les oreilles comme habituellement et la mentonnière se mettra sur le menton du patient. The helmet is applied to the patient's head in the following way the wires connecting the metal parts are placed on the patient's skull, the plastic plates in the shape of a semicircle will be placed under the ears as usual and the chin rest will put on the patient's chin.

On veillera à ménager un espace suffisant entre les fils, qui seront, dans la mesure du possible, tendus. Care should be taken to provide sufficient space between the wires, which will, as far as possible, be stretched.

On voit que, par rapport aux systèmes connus, le dispositif selon l'invention présente les principaux avantages suivants - une seule pièce est nécessaire, - la pièce métallique est plus ferme que les points de jonc
tion en caoutchouc, - cette pièce métallique est conductible avec le courant
électrique, - la mesure de l'électro-encéphalogramme n'est pas affectée quand le malade effectue des mouvements brusques ou des gestes inconscients. It can be seen that, compared to known systems, the device according to the invention has the following main advantages - a single piece is necessary, - the metal piece is firmer than the rod points
rubber, - this metal part is conductive with current
electric, - the measurement of the electroencephalogram is not affected when the patient makes sudden movements or unconscious gestures.
