Claims

[Scope of Claim for Utility Model Registration] (1) In a liquid mixing device having a rubber stopper that is press-fitted into a mixed injection port of a casing and through which an injection needle is inserted to perform mixed injection, a part of the longitudinal direction of the rubber stopper is provided with a liquid injection device in the direction of the center of the mixed injection port. 1. A liquid mixing device characterized by having means for applying compressive stress to. (2) The liquid mixing device according to claim 1, wherein the means for applying compressive stress is a compression band applied to a part of the rubber stopper in the longitudinal direction. (3) The liquid co-infusion device according to claim 1, wherein the compressive stress biasing means is a ring-shaped bulge provided in a portion of the rubber stopper in the longitudinal direction. (4) The liquid mixed injection device according to claim 1, wherein the compressive stress biasing means is provided with a ring-shaped bulge on the inner surface of the mixed injection port.
