An apparatus capable of efficient gelation and jetting of a uniform amount of biopolymer powder, so that there can be accomplished effective utilization of biopolymers in the sealing, arrest of bleeding and prevention of adhesion at operation sites after surgery. There is provided an apparatus including powder delivery pipe (320) for delivering biopolymer powder accommodated in powder agitation vessel (220) after atomization by means of the pressure of nonflammable gas, and separate delivery pipes (310,330) for respectively delivering a nonflammable gas and a solution which are paths other than the powder delivery pipe (320), these delivery pipes all joined together at a distal end of nozzle attachment (400) so that a mixture of biopolymer powder and nonflammable gas is jetted together with the nonflammable gas and solution.

Appareil capable d'une gélification et d'une injection efficaces d'une quantité constante de poudre de biopolymère, de façon à permettre une utilisation efficace de biopolymères dans l'obturation, l'arrêt de saignements et la prévention de l'adhérence au niveau de sites d'opération après intervention chirurgicale. L'invention concerne un appareil comprenant un tuyau de décharge de poudre (320), servant à décharger de la poudre de biopolymère contenue dans une cuve d'agitation de poudre (220) après atomisation au moyen de la pression d'un gaz ininflammable, et des tuyaux de décharge séparés (310, 330) servant à décharger un gaz ininflammable et une solution, respectivement, lesquels sont des voies différentes du tuyau de décharge de poudre (320), ces tuyaux de décharge étant tous reliés à une extrémité distale d'une fixation de buse (400) de façon à ce qu'un mélange de poudre de biopolymère et de gaz ininflammable soit injecté avec le gaz ininflammable et la solution.
