<P>PROBLEM TO BE SOLVED: To provide a medical mixed injection port, completely wiping residual liquid and residual blood off. <P>SOLUTION: This medical mixed injection port includes: a disc-shaped valve 1 whose central part is formed with an insertion hole; a pedestal 7 for supporting the lower part of the peripheral edge of the valve; and a cover 2 for supporting the valve to cover at least the upper part of the peripheral edge of the valve, wherein a fitting hole 6 formed in the inside edge part of the cover functions as a locking means for locking an insertion body to the mixed injection port, the surface of the valve is provided with an annular groove part 4 formed in a boundary between the central part and the peripheral edge part of the valve, and the inner peripheral edge of the cover is provided with an annular piece part 9 formed to engage with the annular groove part. The inside of the annular groove part of the valve is projected over the outside of the groove part on the surface, and the wall thickness of the central part of the valve is larger than that of the peripheral edge part, so that in the state where the valve is not mounted between the pedestal and the cover, a difference D<SB>2</SB>in wall thickness between the central part of the valve and the peripheral edge part thereof ranges from 60% to 80% of the wall thickness D<SB>1</SB>in the inner edge part of the cover, and in the valve mounted state, the wall thickness of the valve central part is increased due to deformation of the valve. <P>COPYRIGHT: (C)2008,JPO&INPIT |
