Kind Code:

B2

Abstract:

A transfer needle assembly including a cap-like outside guide member (1); a tubular inside guide member (2); and a puncture member (3). The puncture member (3) has a tip fitting portion (31) at a proximal end and a puncture needle (32) at a distal end. The inside guide (2) member can slide along an inner wall of a skirt portion (12) of the outside guide member (1) from a position where a distal end of the needle (32) is receded in the inside guide member (2), to a position where the distal end of the needle (32) projects outside of the inside guide member (2). At the position where the distal end of the needle (32) is receded in the inside guide member (2), the outside guide member (1) and the inside guide member (2) are engaged so as to be incapable of sliding, with the engagement being releasable by inserting a mouth portion (41) of a vial (4) into the inside guide member (2).
