Abstract:
PROBLEM TO BE SOLVED: To provide a needleless connector having a novel structure which can further effectively prevent a reverse flow of blood or the like when releasing a male lure.SOLUTION: A needleless connector 10 is provided with an elastic valve 14 having a slit 64 at a tip opening 38 of a chemical liquid path 28 formed in a housing 12, and can switch between communication and cutoff of the chemical liquid path 28 by inserting and releasing a male lure 102. On the elastic valve 14, a deformation part 60 is formed which deforms by inserting and releasing the male lure 102, the elastic valve being in contact with the housing 12 by the deformation of the deformation part 60. Also, a rough surface region is provided on at least one of the deformation part 60 and the housing 12 at a contact face between the deformation part 60 and the housing 12.SELECTED DRAWING: Figure 1
