Definitions

  • the present invention relates to a packaging container for an indwelling needle that accommodates an indwelling needle that remains in a blood vessel when blood dialysis or the like is performed.
  • indwelling needles are accommodated in a prescribed packaging container and are removed by unsealing the packaging container when used.
