Abstract
Description
La présente invention permet d'améliorer la visibilité du tympan par les spéculums à oreilles. The present invention improves the visibility of the eardrum by ear specula.
Dans l'état actuel, les spéculums à oreilles sont tous faits d'une seule pièce conique qui ne comporte aucune partie qui soit mobile par rapport à une autre (figure 1). In the current state, the ear specula are all made of a single conical piece which has no part which is movable relative to another (Figure 1).
Lorsqu'il existe du cérumen dans le conduit auditif, la visibilité du tympan par l'intermédiaire du spéculum est réduite ou nulle. When there is earwax in the ear canal, the visibility of the eardrum through the speculum is reduced or zero.
Le médecin doit alors ménager un premier temps d'évacuation du cérumen qui est pénible et douloureux. The doctor must then arrange a first time of evacuation of the cerumen which is painful and painful.
Le dispositif suivant l'invention permet grâce à ltextrémité ouvrable, de repousser le cérumen, de l'écarter du champ de vision et ainsi d'éviter dans nombre de cas d'évacuer le cérumen au moyen des cotons tiges. The device according to the invention makes it possible, thanks to the opening end, to repel the earwax, to remove it from the field of vision and thus in many cases to avoid evacuating the earwax by means of cotton swabs.
Le spéculum type 1 (figure 2) comporte une extrémité longue et effilée et surtout fendue pouvant donc s'ouvrir comme une valve. La seconde particularité est l'existence d'un applatissement de l'extrémité de manière à former une marche d'escalier formant vuttoir. L'ouverture de la valve supérieure mobile (1) est provoquée par la poussée d'un autre spéculum à extrémité normale (figure 3). Speculum type 1 (Figure 2) has a long, tapered and especially slotted end, which can therefore open like a valve. The second peculiarity is the existence of a flattening of the end so as to form a stair step forming a vuttoir. The opening of the movable upper valve (1) is caused by the push of another speculum with normal end (Figure 3).
Le plan incliné qui constitue la valve mobile (1) peut être constitué en deux parties. Lorsque le speculum pousseur (en pointillé sur la figure 3) est introduit jusqu'au pallier intermédiaire de cette valve mobile, les deux spéculums adhèrent l'un à l'autre et la valve est entrouverte pour permettre la visibilité du champ ; c'est la position d'introduction. The inclined plane which constitutes the movable valve (1) can be made up of two parts. When the pusher speculum (dotted line in FIG. 3) is introduced up to the intermediate level of this movable valve, the two specula adhere to one another and the valve is ajar to allow visibility of the field; this is the introductory position.
Fonctionnement :
un spéculum normal est introduit dans l'oreille. Si cette première vision montre la présence de cérumen abondant, le spéculum est retiré, recouvert par le spéculum à extrémité ouvrable en position d'introduction (voir plus haut).Operation:
a normal speculum is introduced into the ear. If this first vision shows the presence of abundant earwax, the speculum is removed, covered by the speculum with openable end in the insertion position (see above).
L'extrémité effilée est introduite soit dans un petit orifice existant dans le bouchon de cérumen, soit glissé entre le bouchon et la paroi du conduit s'il n'existe aucun orifice. Une simple pression permet alors l'ouverture du spéculum et une bonne visibilité du tympan, le cérumen ayant été repoussé sur les cotés
Spéculum type 2 (figure 4):
l'extrémité large du spéculum est évidée, selon une coupe triangulaire, sur les deux bords diamètralement opposés. The tapered end is introduced either into a small opening existing in the earwax plug, or slid between the plug and the wall of the duct if there is no opening. A simple pressure then allows the opening of the speculum and good visibility of the eardrum, the earwax having been pushed back on the sides
Speculum type 2 (Figure 4):
the wide end of the speculum is hollowed out, in a triangular cut, on the two diametrically opposite edges.
Fonctionnement
ici l'ouverture de l'extrémité fendue est provoquée par la simple pression sur le gros bout du spéculum, comme par un système de levier autour du point A. Ce sépculum s'utilise donc seul et non à deux came le type 1.Operation
here the opening of the split end is caused by the simple pressure on the large end of the speculum, as by a lever system around the point A. This sepculum is therefore used alone and not with two cam type 1.
Le spéculum objet de l'invention permet de voir les tympans sans éva cation de cérumen préalable. The speculum object of the invention allows to see the eardrums without evacuation of earwax.
