<p>A medical valve, to which a male luer (37) is to be separably connected, comprises: (a) a housing (1) having a hollow body opened at the top end, wherein the tip (38) of the male luer (37) is to be removably inserted in the housing (1); (b) a spike (2) disposed to extend longitudinally in the housing (1), the spike (2) except at least the top end portion being formed in an approximately tapered shape in which its outside diameter becomes progressively smaller toward the top end portion, wherein fluid transferring passage (28), which is opened radially outwardly, is formed to extend longitudinally in the spike (2), the bottom portion of the fluid transferring passage (28) being connected to a fluid circuit; and (c) an elastic seal (3) having an elastically deformable tubular shape fitted on the spike (2) to seal the spike (2), the elastic seal (3) comprising a top end portion having an openable/closable portion (29) to be openably closed over the spike (2), wherein the elastic seal (3) is elastically deformed to be downwardly shrunk by downward pressure due to the tip (38) of the male luer (37), thereby the openable/closable portion (29) is brought into abutment with the spike (2), and is elastically deformed to be opened radially outwardly to be fitted onto the spike (2), so that the inside of the male luer (37) communicates with the fluid transferring passage (28) of the spike (2). <IMAGE></p> |
