Sealing agent for genitals

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.

1 . 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.   
     
     
         2 . The sealant for reproductive organs according to  claim 1 , comprising:
 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).   
     
     
         3 . The sealant for reproductive organs according to  claim 2 ,
 wherein the polyisocyanate component (A) contains 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).   
     
     
         4 . The sealant for reproductive organs according to  claim 2 ,
 wherein the NCO-terminated urethane prepolymer (UP) has an isocyanate group content of 1 to 10 wt % based on the weight of the NCO-terminated urethane prepolymer (UP).   
     
     
         5 . The sealant for reproductive organs according to  claim 2 ,
 wherein the NCO-terminated urethane prepolymer (UP) has a total content of urethane groups and urea groups of 1 to 20 wt % based on the weight of the NCO-terminated urethane prepolymer (UP).   
     
     
         6 . The sealant for reproductive organs according to  claim 2 ,
 wherein the hydrophilic polyol (B1) has an oxyethylene unit content of 30 to 90 wt % based on the weight of the hydrophilic polyol (B1).   
     
     
         7 . The sealant for reproductive organs according to  claim 2 ,
 wherein the polyol component (B) has an oxyethylene unit content of 30 to 90 wt % based on the weight of the polyol component (B).   
     
     
         8 . The sealant for reproductive organs according to  claim 1 ,
 wherein the cured product (X) has a contact angle with water of 60° to 110° .   
     
     
         9 . The sealant for reproductive organs according to  claim 1 ,
 which is used to prevent amniotic fluid leakage from a uterus.   
     
     
         10 . The sealant for reproductive organs according to  claim 1 ,
 wherein the reproductive organs is a cervical canal.
