A mixture injection port is capable of suppressing the continuous accumulation of medical fluid or blood therein and allowing efficient internal cleaning. A recirculation part is formed at a step between an inner cavity and a narrow tube part. Even if the fluid is accumulated in a clearance area produced in the inner cavity when a luer is inserted into a slit, the fluid can be securely replaced with the fluid newly flowing therein through a septum and the continuous accumulation of the fluid can be suppressed. A more efficient internal cleaning can be realized by installing a fluid accumulation prevention part such as an annular rib between the septum and the inside wall of the inner cavity and burying the clearance area.

A canine femoral stem system provides a set of sizes of stems designed to fit in a reamed femoral bone canal with controlled interference. The canine femoral stems can be implanted using either a cemented or cementless procedures. Cementless stems have a porous coating of sintered beads on the tapered proximal section providing interference with reamed femoral canal causing friction and initial stability.
