Embodiment 1

[0036] like figure 1 As shown, the novel contraceptive device of the present embodiment comprises: silkworm cocoon 1, filler 3, pull wire 2 and pasting sheet 4;

[0037] Silkworm cocoon 1 is a natural silkworm cocoon and has an opening;

[0038] The pull wire 2 is a cotton thread. The pull wire 2 passes through the cotton ball first, then penetrates through the opening of the silkworm cocoon 1 and penetrates the outer wall of the silkworm cocoon 1, and then passes through the outer wall of the silkworm cocoon 1 and returns to the inside of the silkworm cocoon 1. The pull wire 2 continues to pass through the cotton ball by the silkworm cocoon 1. At this time, the pull wire 2 leaves two free ends at the opening of the silkworm cocoon 1; after the drug-carrying device is placed in the body, the silkworm cocoon 1 is taken out by pulling the pull wire 2;

[0039] During the penetration process of the above-mentioned stay wire 2, the cotton ball is located outside the silkworm coco...

Embodiment 2

[0047] The difference between the new contraceptive device of this embodiment and that of Example 1 is that the Chinese medicine extract is obtained by extracting from one of cloves, flavescens, cnidium, saponins, and hundred. It is a traditional Chinese medicine with good in vitro spermicidal effect, so whether one or several of them are used, similar effects can be achieved.

Embodiment 3

[0049] The new contraceptive device of this embodiment is different from that of Embodiment 1-2 in that: the filler 3 is a highly water-absorbent carrier sponge soaked in the extract of traditional Chinese medicine;

[0050] The usage and contraceptive effect of this embodiment are the same as those of Embodiment 1.
