Abstract

Dispositif permettant d'obtenir une sécurité intrinsèque par rapport à l'air pouvant être véhiculé dans la tubulure d'un goutte à goutte en particulier lorsque le flacon est vide. Il comporte un rotor constitué par une roue à galets comprimant la tubulure de goutte à goutte contre un stator élastique; les galets d'une part, ou le stator d'autre part, sont munis d'une encoche permettant d'obtenir sur la face plate comprimée de la tubulure un seul orifice capillaire dont la dimension permet une étanchéité en présence de liquide et une communication entre amont et aval de la tubulure en présence d'air ce qui rend dans ce cas le pompage impossible. Le même résultat peut être obtenu avec un seul rotor, sanss stator, en tirant la tubulure sur ledit rotor dont les galets ou le profil polygonal seront munis de l'encoche permettant d'obtenir un seul orifice capillaire situé sur la partie plate comprimée de la tubulure L'invention peut être utilisée dans tous les systèmes de goutte à goutte
