| 摘要 |
The invention concerns a gynaecologycal device for insertion in a woman's womb, i.e., an intrauterine device. This device includes a Y-shaped flexible support means, the branches of which are each provided with a fanlike, inwardly extending membrane covering at least part of the space between the two branches. This intrauterine device has the advantage of enabling its part which penetrates into the uterus to unfold after introduction therein so as to cover up practically the whole internal wall of the uterus.
