Abstract
A medical valve includes: (a) a housing having a hollow body opened at the top end, wherein the tip of a male luer is to be removably inserted in the housing; (b) a spike disposed to extend longitudinally in the housing, the spike 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 a fluid transferring passage, which is opened radially outwardly, is formed to extend longitudinally in the spike; and (c) an elastic seal having an elastically deformable tubular shape fitted on the spike to seal the spike, the elastic seal including a top end portion having an openable/closable portion to be openably closed over the spike, wherein the elastic seal is elastically deformed to be downwardly shrunk by downward pressure due to the tip of the male luer.
