Abstract

The present invention provides a vaginal administration apparatus, which relates to a medical apparatus for curing gynecologic diseases. The vaginal administration apparatus includes an outer tube and a pushing ram, which extends into the inside of the outer tube and can relatively move towards the outer tube. The front end of the outer tube is provided with a cylindrical medicine cavity, which has a bigger diameter and can contain a medicament. The caudal end of the outer tube is provided with a retainer ring. The vaginal administration apparatus is characterized in that a medicine claw is arranged at the front end of the pushing arm. The medicine claw consists of more than two petaloid memory metal coupons. When the medicine claw is inside the medicine cavity, under the affect of the medicine cavity wall, each memory metal coupon folds to be a cystic form; when the medicine claw extends outside the medicine cavity, the memory metal coupons automatically open. The caudal end of the pushing arm is provided with a pushing plate. A compression spring is mounted on the pushing arm between the retainer ring and the pushing plate. Under the effect of the compression spring, the medicine claw is inside the medicine cavity, and the pushable distance of the pushing plate is longer than the medicine cavity length. The present invention has the advantages of wide application range, simple structure and convenient self administration.
