| 摘要 |
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.
