Title (EN) APPARATUS FOR THE MICROSCOPICALLY-DOSED INJECTION OF AN ACTIVE PRODUCT BY MEANS OF JETS OF PRESSURISED WORKING LIQUID AND THE METHOD OF GENERATING A SEQUENCE OF LIQUID JETS USING SAID APPARATUS
(FR) APPAREIL D'INJECTION MICRODOSÉE D'UN PRODUIT ACTIF PAR DES JETS DE LIQUIDE DE TRAVAIL SOUS PRESSION ET PROCÉDÉ DE GÉNÉRATION D'UNE SÉQUENCE DE JETS LIQUIDES AU MOYEN DE CET APPAREIL.
Abstract: front page image
(EN)The invention relates to an injection apparatus (1) which blasts pressurised working liquid against the tissue to be treated in order to hollow out an injection channel and which subsequently injects the active product into said channel. The inventive apparatus comprises a reserve of working liquid (2) which can be pressurised and which is connected to a handpiece (5) by means of a main branch (4) of the fluid system. An active end piece (8) is disposed at the end of said handpiece comprising outlet means for a pressurised jet of working liquid. Moreover, the invention comprises a secondary branch opening (15) which is parallel to the main branch and which is fluidically isolated from same. Said secondary branch is intended to contain the active product. According to the invention, a multiplexing means (24) is used independently to control the opening and closing of the isolation valves (22, 23) of each of the two branches of the system according to pre-determined parameters.
(FR)L'appareil d'injection (1) envoie un tir de liquide de travail sous pression contre le tissu à traiter pour creuser un canal d'injection, puis injecte le produit actif dans ce canal. L'appareil comprend une réserve de liquide de travail (2) pouvant être mise sous pression, reliée par l'intermédiaire d'une branche principale (4) du circuit fluidique à une pièce à main (5) se terminant par une extrémité active (8) comportant des moyens de sortie d'un jet sous pression de liquide de travail. Il comporte en outre une branche secondaire de dérivation (15), parallèle à la branche principale et isolée fluidiquement de celle-ci, destinée à contenir le produit actif. Un moyen de multiplexage (24) permet de commander de façon indépendante l'ouverture et la fermeture de vannes d'isolement (22, 23) de chacune des deux branches du circuit selon des paramètres prédéterminés.
