PROBLEM TO BE SOLVED: To provide a medical valve with a novel structure which prevents stagnation of fluid such as medicinal solution and improves the durability of a valve body.SOLUTION: A disk-shaped elastic valve body 38 is arranged with respect to an opening member constituting an opening part of a fluid flow passage by causing engaging protrusion parts 70, 80 to engage with annular grooves 54, 56 provided on an outer peripheral part of the elastic valve body 38. An annular fixing part 46 of the elastic valve body 38, provided on an outer peripheral side of the annular grooves 54, 56, is fixedly supported by the opening member. On the other hand, a recessed groove part opening toward an inner surface of the elastic valve body 38 is formed. Insertion resistance of a male connector 104 into a slit 48 is reduced by allowing elastic deformation of an inner surface shape of the recessed groove part when the male connector 104 is inserted into the slit 48.SELECTED DRAWING: Figure 14 |
