<P>PROBLEM TO BE SOLVED: To provide a rubber member for a mixed injection tube with which a cause of coring and scattering of a medical fluid or blood when a needle is removed can be prevented or decreased by decreasing puncture resistance or expansion resistance. <P>SOLUTION: A shaded part of the figure shows a partial cross section of an elastic member for the mixed injection tube of the invention. The elastic member 8 for the mixed injection tube includes a head portion 8d at the top part of a main body, a downward projection 8c at the lower edge of the main body and a collapsed hole 8e at the central portion. Also, a vertical groove 8b is formed on a circumference of a wall of the main body which has a corresponding protrusion 8a. The vertical groove 8b, as an implementation form, leaves a part of the circumference 8f near the head portion 8d and has an open end 8g at the lower edge. A puncture resistance or expansion resistance is decreased with two or more vertical grooves on at least a part of the circumference of the wall of the elastic member so that the cause of coring and scattering of the medical fluid or blood when the needle is removed can be prevented or decreased. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
