Title:
PUNCTURE NEEDLE CONNECTOR AND CONNECTING TUBE
Document Type and Number:
WIPO Patent Application WO/2017/150398
Kind Code:
A1
Abstract:
A puncture needle connector (1) includes an outer cylinder (11), an inner cavity (1a) formed inside the outer cylinder (11), an elastically deformable arm (15) provided on the outer cylinder (11), and a hook (16) provided on the arm (15). The inner cavity (1a) communicates with the outside via a first opening (21) and a second opening (22). When a puncture needle (210) is inserted into the inner cavity (1a) through the first opening (21), the hook (16) is engaged with an engaging structure (217) provided as an integral part on the puncture needle (210), thus forming a liquid-tight seal (25) between the outer circumferential surface of the puncture needle (210) and the inner circumferential surface of the inner cavity (1a) and allowing the puncture needle (210) and the second opening (22) to communicate with each other.
