PURPOSE: To provide a storage needle which prevents the blood in counter-flow from leaking at the storage needle on its side with the connection part and which can perform cleanly the liquid or blood transfusing works, artificial dialyzing works, etc.

CONSTITUTION: A pipe part 2 for flowing-in and -out of a liquid and a pipe part 4 for insertion and drawing-out of an inner needle 3 are divergently provided on the base side 1A, and a resilient member 5 is installed in the pipe part 4. In a storage needle 1 of the described structure, an inner cylinder 3 is put piercing the skin in such a condition as inserted in an outer cylinder 6, and in the case the inner needle 3 is drawn off from an opening 40 provided in the pipe part 4 after insertion of the outer cylinder 6 is in a blood vessel, blood leakage from the opening 40 is prevented through restroation such that the resilient member 5 blocks a through hole due to the inner needle 3. The transfusive liquid, blood, etc., from the outside is fed in the direction of the outer cylinder 6 from the flowin/flowout pipe part 2. The blood from the blood vessel is sent out in the direction of the pipe part 2 from the outer cylinder 6.
