Abstract
Description
La présente invention concerne le do#maine médical. Elle appor
te une aide au diagnostic des pertes de sensibilité superficielles:
tactile, douloureuse et thermique, ainsi sutà celui du réflexe pupilraire.The present invention relates to the medical field. She appor
help you with the diagnosis of superficial sensitivity loss:
tactile, painful and thermal, so sutà that of the pupilary reflex.
Jusqu'a présent, l'examen des sensibilités tactiles est fait avec un pinceau ou un coton, celui de la sensibilité douloureuse avec une aiguille ou par pincement, celui de la sensibilité thermique avec des éprouvettes replies d'eau chaude R 4c~45e et d'eau froide da 4 4 i5 . Until now, the examination of tactile sensitivities is done with a brush or a cotton, that of painful sensitivity with a needle or by pinching, that of thermal sensitivity with test tubes filled with hot water R 4c ~ 45e and cold water da 4 4 i5.
Durant l'examen clinique, il est fréquent que lés liquides se réchauffent, se refroidissent ou se renversent. De même, il est rare que les objets nécéssaires aux quatre tests soient réunis au même moment et au même endroit, ce qui rend souvent l'examen neurologique incomplet. During the clinical examination, it is common for liquids to warm, cool, or spill. Similarly, it is rare that the objects necessary for the four tests are gathered at the same time and in the same place, which often makes the neurological examination incomplete.
La présente invention entend remédier à ces inconvénients en réunissant,en un même objet transportable, tous les instruments nécéssaires à l'e:amen des trois types de sensibilités superficielles. ret objet comportera donc une source de chaud, une source de froid, une
un pinceau.The present invention intends to remedy these drawbacks by bringing together, in the same transportable object, all the instruments necessary for e: amen of the three types of surface sensitivities. ret object will therefore include a source of heat, a source of cold, a
a brush.
