Embodiment 1

[0015] 1. Drugs and preparations:

[0016] 1. Estrogen: raw material drug of estradiol; traditional Chinese medicine: Chuanxiong.

[0017] 2. Silicone rubber compound: purchased from Shanghai Rubber Products Research Institute. The silicone rubber used in the present invention is a two-component room temperature vulcanized silicone rubber. Before vulcanization, there are two components, A and B. Among them, the A component contains a catalyst, and the B component contains a crosslinking agent. They do not react with each other, and after blending with each other, the polymerization reaction can be carried out because the catalyst and the crosslinking agent are mixed together.

[0018] Second, equipment

[0019] Pressure forming machine (model: XLB-D400-400), rubber mixing machine (model: JTC-752A), electronic platform scale (model: TSC-6), electric blast drying oven (model: 101A-1B), drying oven ( Model: 101-3), three-roll mill (model: SG-150), weighing display (model: XK31...

Embodiment 2

[0026] One, medicine and preparation: Same as Example 1.

[0027] Two, equipment: with embodiment 1.

[0028] 3. Material preparation: Weigh 100 g of silicone rubber material, 30 g of estradiol, and 10 g of Rhizoma Chuanxiong. Others are the same as in Example 1.

[0029] 4. Vaginal mold preparation: Same as Example 1.

Embodiment 3

[0031] One, medicine and preparation: Same as Example 1.

[0032] Two, equipment: with embodiment 1.

[0033] 3. Material preparation: Weigh 100 g of silicone rubber material, 50 g of estradiol, and 8 g of Rhizoma Chuanxiong. Others are the same as in Example 1.

[0034] 4. Vaginal mold preparation: Same as Example 1.

Abstract

The invention relates to a material used for preparing moulds. The material is composed of silicone rubber, estradiol and ligusticum wallichii at a weight ratio of 20:(5-8):(1-4). An advantage of the material is that, the mould material which contains estrogen and traditional Chinese medicine is capable of reducing contracture rate of artificial vagina. Silicone rubber, estrogen and traditional Chinese medicine are used together for preparation of vagina moulds with controlled-release capacity on estrogen, so that a treating method by using the vagina moulds and a treating method by combination of traditional Chinese and western medicine are combined effectively. It can be concluded from above that, the vagina moulds with controlled-release capacity have a promising prospect in clinical applications.

Description

technical field [0001] The invention relates to a material for preparing molds. Background technique [0002] Most patients with congenital absence of vagina have Rokitansky-Kuster-Hauser syndrome (RKH syndrome), which is the result of bilateral paramesonephric duct hypoplasia during the embryonic period, and the karyotype is 46XX. The treatment of patients with congenital absence of vagina has surgical treatment and non-surgical treatment. Surgical treatment includes vulvovaginoplasty (Williams method), acupoint skin grafting method (McIndol method), peritoneal vagina replacement method (Rothman method), sigmoid colon replacement vagina method (Pratl method), amniotic membrane replacement vagina method, and new biomaterial vaginal reconstruction, etc. , The application of the vaginal mold is a very important part of the post-vaginoplasty treatment. A vaginal mold should be placed for 3 months to half a year after the operation to prevent contracture of the artificial vagi...
