Abstract:
1. A medical valve, to which a male luer is to be separably connected, comprising: (a) a housing having a hollow body opened at the top end, wherein the tip of the male luer is to be removably inserted in the housing; (b) a longitudinal solid spike disposed to extend longitudinally in the housing, the spike except at least the top end portion being formed in a shape approximately tapered upwardly, wherein a groove-shaped fluid transferring passage, which extends the entire longitudinal length of the spike is formed on the outer peripheral surface of the spike, the bottom portion of the fluid transferring passage being connected to a fluid circuit; and (c) an elastic seal having an elastically deformable tubular shape fitted on the spike to seal the spike, the elastic seal comprising 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 compressed by downward pressure due to the tip of the male luer, thereby the openable/closable portion is brought into abutment with the spike, and is elastically deformed to be opened radially outwardly to be fitted onto the spike, so that the inside of the male luer communicates with the fluid transferring passage of the spike.
