<p>PURPOSE:To improve the blood preservation performance and stability by forming the clothes medical instrument such as blood bag from the resin composition which is formed by compounding the malic acid dialkyl ester having special general formula and stabilizing agent having each special ratio, into a vinyl chloride group resin. CONSTITUTION:As for a medical instrument e.g. blood bag, a blood taking-out tube 6 made of a resin composition is connected to a blood taking-out bag 3 made of the resin composition. With the blood taking-out bag 3, a plurality of subsidiary bags 13 and 22 made of the resin composition are connected by the respective connecting tubes 12 and 21 made of the resin composition. In this case, the resin composition is formed by compounding 5-100 pts.wt. of malic acid dialkyl ester having the general formula shown separatedly and 1-20 pts.wt of a stabilizing agent into 100 pts.wt of the vinyl chloride group resin. In the general formula shown separatedly, each of (a) and (b) is 2-12, and R is a hydrogen atom, acetyl group, propionyl, or butylyl group.</p> |
