Title
(EN) NEEDLELESS INJECTION SYSTEM
(FR) SYSTÈME D'INJECTION SANS AIGUILLE
Abstract
(EN)
Needleless injection system (100), comprising: - a mixing chamber (101) in which particles of a solid dermatological or cosmetic composition are mixed with a volume of gas with a view to the injection thereof into human keratin materials, - a mechanism for propelling the particles of the solid composition that are present in the mixing chamber (101) into the human keratin materials - at least one second reservoir (105) containing and/or intended to receive the solid composition, - a transfer and/or disintegration member (3) in contact with the solid composition contained in the second reservoir (105), made to perform a relative movement in relation to said solid composition in order to dispense the solid composition in particulate form into the mixing chamber (101).
(FR)
L'invention concerne un système d'injection sans aiguille (100), comprenant : - une chambre de mélange (101) dans laquelle des particules d'une composition cosmétique ou dermatologique solide sont mélangées avec un volume de gaz en vue de leur injection dans des matières kératiniques humaines, - un mécanisme permettant la propulsion des particules de la composition solide, présentes dans la chambre de mélange (101), dans les matières kératiniques humaines, - au moins un second réservoir (105) contenant et/ou destiné à recevoir la composition solide, - et un organe de transfert et/ou de désintégration (3) en contact avec la composition solide contenue dans le second réservoir (105), conçu pour effectuer un mouvement relatif par rapport à ladite composition solide afin de distribuer la composition solide sous forme particulaire dans la chambre de mélange (101).
