Abstract

L'invention concerne des équipements au plasma et notamment des dispositifs de traitement de plaies au plasma et peut s'utiliser pour un traitement complexe des blessures chroniques, infectées ou aigues. Le dispositif de traitement de plaies au plasma comprend un corps cylindrique, un embout conique et une électrode axiale. L'embout est réalisé sous la forme d'une buse avec un orifice central et un circuit de refroidissement. L'électrode axiale est montée dans le corps au moyen d'une cartouche coaxiale isolante dotée de canaux longitudinaux. Le dispositif est doté d'un manchon d'extrémité dans lequel est fixé la partie terminal d'une électrode axiale et sont réalisés des canaux longitudinaux qui coïncident, une fois assemblés, avec les canaux de la cartouche. Le manchon et la cartouche sont munis d'un canal d'amenée de gaz de travail qui communique avec l'orifice central de la buse, des canaux d'amenée et des canaux d'évacuation de liquide de refroidissement communiquant avec le circuit de refroidissement de la buse ainsi qu'un canal d'alimentation électrique dans lequel est disposé un câble électrique alimentant en courant l'embout conique. L'invention permet d'améliorer la fiabilité de fixation des éléments les uns par rapport aux autres.
