PURPOSE:To provide a biomedical adhesive which allows the shortening of hardening time while excelling in adhesion strength with the elimination of histotoxin for joining organic tissues after surgery operation or on other occasions by using a biomedical adhesive made of gelatin and urethane prepolymer containing an isocyanate group expressed by a specified formula. CONSTITUTION:This biomedical adhesive is made of a gelatin and urethane prepolymer containing an isocyanate group expressed by the formula, in which (m) is an integer of 1-100 and (n) an integer of 1-100 and (m) and (n) has a relationship specified by 0.3<=n(m+n)=0.9. A propylene oxide unit may be coupled to an ethylene oxide unit at random. The adhesive thus obtained is short in hardening time, has no histotoxin, and provides excellent adhesion strength. |
