| abstract | PROBLEM TO BE SOLVED: To provide the same rigidity at the time of puncture and the flexibility after indwelling in blood as a fluororesin indwelling catheter, and to show the optimal elasticity reduction behavior for indwelling operation, and to have kink resistance. To provide an indwelling catheter which is excellent in quality. SOLUTION: An indwelling catheter comprising a plurality of polyurethane resins containing polyglycols having different molecular weights, The dynamic storage elastic modulus in the dry state at 25 ° C. is 1 GPa or more, and the decrease rate of the dynamic storage elastic modulus when the time t has elapsed from the dry state at 25 ° C. to the wet state at 37 ° C. has passed 20 seconds. Sometimes less than 60% and more than 60% after 1 minute. Each polyurethane resin contains diisocyanate, diol-based chain extender and polyglycol as main components. The plurality of polyurethane resins consist of a first polyurethane resin containing a polyglycol having a molecular weight of 500 to 1500 and a second polyurethane resin containing a polyglycol having a molecular weight of 1500 to 3000, and the difference in molecular weight of the polyglycol is 500 or more. It is. |
