Title:
Needle Lesco nectar
Document Type and Number:
Japanese Patent JP6102747
Kind Code:
B2
Abstract:
A bottomed, tubular hollow elastic body (16) that opens toward an outlet side of a drug solution flow path (80) is accommodated and arranged in an accommodation part (20) formed in a housing (12), and a middle protrusion (66) is provided protruding toward an inlet side of the drug solution flow path (80) from a center part of a bottom wall (70) of the hollow elastic body (16). Insertion of a male luer (86) causes the bottom wall (70) of the hollow elastic body (16) to be elastically deformed so as to enter inside a peripheral wall (68), increasing the volume of the drug solution flow path (80), which is formed between an outer surface of the hollow elastic body (16) and an inner surface of the accommodation part (20). Removing the male luer (86) and canceling the elastic deformation of the hollow elastic body (16) causes the volume of the drug solution flow path (80) to be reduced.
