CA 2443292

This invention relates to a vaginal cannula which allows drugs of different physical forms, such as gel and a tablet, which must remain separate until the time of use, to be introduced into the vagina simultaneously. The instrument in accordance with the invention consists of a vaginal cannula (1), the distal part of which contains a separator (3) which separates the substances to be delivered and is configured in such a way that it also expels a tablet (5). A plunger (2) inserted in the proximal part of the cannula compresses the gel (4) contained in the cannula, causing it to exit through a set of holes in the cannula wall in a suitable position. The subsequent travel of the plunger after expulsion of the gel causes it to engage with a separator/ejector system (3) so as to push the separator against a tablet housed in the anterior extremity of the cannula and expel it directly into the vagina.

L'invention porte sur une canule vaginale qui permet l'introduction simultanée, dans le vagin, de médicaments de différentes formes physiques, tels que des gels et des comprimés, lesquels ne doivent pas être en contact jusqu'à leur utilisation. L'instrument selon l'invention consiste en une canule vaginale (1) dont la partie distale contient un séparateur (3) qui sépare les substances à administrer et est configuré de manière qu'il expulse aussi un comprimé (5). Un piston (2) inséré dans la partie proximale de la canule comprime le gel (4) contenu dans la canule afin de le faire sortir à travers plusieurs trous sur la paroi de la canule dans une position adéquate. Ensuite, le trajet du piston après l'expulsion du gel fait qu'il vient en prise avec un système séparation / éjection (3) afin de repousser le séparateur contre un comprimé logé dans l'extrémité antérieure de la canule et de l'introduire directement dans le vagin.
