SUBCUTANEOUS INFUSION DEVICE

PROBLEM TO BE SOLVED: To provide a subcutaneous infusion device ensuring aseptic properties when an indwelling member is separated from a connection member and certainly preventing a medical fluid from exposing to a user. SOLUTION: The subcutaneous infusion device is used for infusing the medical fluid into the body of the user and equipped with the indwelling member 10 and the connection member 20 attached to the indwelling member 10 in a detachable manner by slide movement. The connection member 20 includes a body part 21, a needle 20B provided to the body part 21 and communicating with a cannula 12 when the connection member 20 is attached to the indwelling member 10 and the needle cover 20A fixed to the body part 21, formed so as to cover the needle 20B when the connection member 20 is detached from the indwelling member 10, contracted in its axial direction upon the reception of compression force from the indwelling member 10 when the connection member 20 is attached to the indwelling member 10 to permit the needle 20B to pierce to thereby allow the same to communicate with the cannula 12.
