The invention concerns a device to improve the coagulation of moderately or heavily bleeding live human and animal tissue and to form an eschar by means of a plasma jet. The device comprises plasma- generating means consisting of an electrically conductive body (6) which is connected to a positive pole of a basic energy source having a positive potential. The body (6) is formed with a cylindrical channel (17) designed to heat the plasma-generating gas. The channel (17) is formed from a number of sections (8, 9, 10) which are electrically insulated from each other and each one of which is connected to the body (6) via bushes (22). The bushes are concentric with the sections (8, 9, 10) and are electrically insulating. The bushes (22) are formed with channels (19) arranged to conduct cooling liquid to and from the gas-heating channel (17).
L'invention concerne un dispositif conçu pour améliorer la coagulation de tissus vivants saignant modérément ou abondamment chez l'homme et chez les animaux et pour former une croûte du type escarre au moyen d'un jet de plasma. Ce dispositif comporte un moyen de génération de plasma consistant en un corps électroconducteur (6) qui est connecté à un pôle positif d'une source d'énergie de base à potentiel positif. Le corps (6) est constitué d'un canal cylindrique (17) conçu pour chauffer le gaz générant le plasma. La canal (17) est formé à partir de plusieurs sections (8, 9, 10) qui sont isolées électriquement les unes des autres, chacune étant connectée audit corps par des douilles (22) concentriques avec les sections (8, 9, 10) et isolées électriquement. Ces douilles (22) sont dotées de canaux (19) permettant la circulation du liquide de refroidissement en direction du canal chauffant le gaz (17) et en provenance de celui-ci.
