Abstract
The present invention aims to provide a cervical canal sealant that can be used as a sealant to stop bleeding in the uterus and vaginal discharge, particularly, a cervical canal sealant that can block the cervical canal to inhibit amniotic fluid leakage and that can also be peeled off without damaging reproductive tissue. The present invention relates to a sealant for reproductive organs in which a cured product (X) at 25° C. has a storage modulus G′ of 200 to 2,000 kPa, the cured product (X) being a cured product obtained by curing the sealant for reproductive organs to a thickness of 120 to 150 μm.
Claims13
A method for sealing a reproductive organ, comprising:
- applying a sealant to a reproductive organ,
- curing the sealant, and
- peeling off the cured sealant from the reproductive organ,
- wherein the sealant comprises:
- an NCO-terminated urethane prepolymer (UP) that is a reaction product of a polyisocyanate component (A) and a polyol component (B) containing a hydrophilic polyol (B1), wherein the polyisocyanate component (A) comprises a fluorine-containing non-aromatic polyisocyanate compound (A1), and the NCO-terminated urethane prepolymer (UP) has a fluorine content of 1 to 23 wt % based on the weight of the NCO-terminated urethane prepolymer (UP), and
- when the sealant is spread to a thickness of 120 to 150 μm and cured, a sample of the sealant is obtained as a cured product (X) having a storage modulus G′ of 200 to 2,000 kPa at 25° C.
A method for preventing amniotic fluid leakage from a uterus, comprising:
- applying a sealant to a uterus,
- curing the sealant, and
- peeling off the cured sealant from the uterus,
- wherein the sealant comprises:
- an NCO-terminated urethane prepolymer (UP) that is a reaction product of a polyisocyanate component (A) and a polyol component (B) containing a hydrophilic polyol (B1), wherein the polyisocyanate component (A) comprises a fluorine-containing non-aromatic polyisocyanate compound (A1), and the NCO-terminated urethane prepolymer (UP) has a fluorine content of 1 to 23 wt % based on the weight of the NCO-terminated urethane prepolymer (UP), and
- when the sealant is spread to a thickness of 120 to 150 μm and cured, a sample of the sealant is obtained as a cured product (X) having a storage modulus G′ of 200 to 2,000 kPa at 25° C. is obtained.
