4、 Maternal and abdominal birth weight with long-term, sustained and continuous release of progesterone helps prevent preterm birth

摘要

The weight contains progesterone distributed in the body of weight, providing long-term, continuous and continuous release, at least 6 months. The weight consists of dimethylsilicone elastomer with RTV (room temperature vulcanization) mechanism,The amount of progesterone is between 20% and 30% P / P, and between 6:1 And 14:1, depending on the weight and the proportion of the polymer that makes up the mother. The weight of caesarean section is beneficial to prevent premature delivery. Without changing the shape and integrity of the weight, the estrogen is continuously transmitted through the polymer, because the elastomer that forms the polyimide matrix used in the present invention is not biodegradable. This ensures that the shape of the weight remains unchanged until the end of the treatment.
