Abstract

The invention discloses a contraceptive ring and a preparation method of the contraceptive ring. The contraceptive ring is prepared from silica gel, nano copper powder and a cross-linking agent. The preparation method comprises the steps of putting the silica gel in a rubber mixing mill for mixing according to a raw material proportion, gradually adding the nano copper powder into the silica gel for uniform mixing, adding the cross-linking agent into the rubber mixing mill to form mixed colloid, putting the mixed colloid in a mold for warming and pressing to form a finished product, and performing aging, sterilization and disinfection treatment on the finished product according to medical and sanitary requirements. The contraceptive ring is smooth in surface and soft and elastic in texture, has no stimulation, is not combined with a human body and does not result in bleeding and pain when the contraceptive ring is in contact with the human body.

Description

technical field [0001] The invention relates to the medical field, in particular to a birth control ring and a preparation method thereof. Background technique [0002] After the original product in the market is made of silica gel, the copper ring or copper wire is wound or wrapped on the surface of the finished silica gel fertilization ring, so that the contraceptive effect appears from below. But it is not smooth, the softness is not good, the elasticity is not good, and the contact with the human body is irritating, and the contact with the human body will combine with the human body, which will cause disadvantages such as bleeding and pain. [0003] There are also drugs added to the fertility ring, and the drug-added fertility ring will have no contraceptive effect after the drug volatilizes, and the service life is too short, not smooth, not soft, not elastic, and in contact with the human body It is irritating, and it will be combined with the human body when it come...
