SELF-DEGRADABLE TWO-COMPONENT REACTIVE ADHESIVE FOR MEDICAL USE AND RESIN FOR MEDICAL USE

摘要

It is aimed to provide medical-use adhesive and medical-use hydrogel resin that satisfy general requirements for such adhesive and resin and are rapidly disintegrated at an elapse of designed time period, which may be rather freely controlled or adjusted. A first liquid for the adhesive or the resin is an aqueous solution of aldehyde-groups-introduced alpha-glucan having a weight-average molecular weight in a range of 1000 to 200,000. A second liquid for the adhesive or the resin is aqueous solution of amino-groups-containing polymer that is formed of a polymer chain of amino-group-containing units and has a molecular weight in a range of 1000 to 20,000. A mixture of the first and second liquids at a time of mixing them has pH in a range of 5.0 to 8.0.
