The purpose of the present invention is to provide a dialysis agent A, which is able to set the total acetate ion content in the dialysate to a low value, excellent in storage stability of glucose, able to reduce the acetic acid odor, and able to suppress the corrosion of the dialysate delivery system and the dialysis machine, as well as to provide a two pack type dialysis agent utilizing the dialysis agent A.
In the dialysis agent A used in the preparation of a bicarbonate dialysate, which is used as one part of a two pack type dialysis agent, it becomes possible to prepare a bicarbonate dialysate having the total acetate ion concentration of between 2 mEq/L or more and less than 6 mEq/L by allowing to include glucose, acetic acid and acetate salt and to satisfy the molar ratio of 1:0.5 to 2 of acetic acid and acetate salt, and include acetic acid and acetate salt in a total amount of between 2 mEq or more and less than 6 mEq in the dialysis agent A required to prepare 1 L of the bicarbonate dialysate. Moreover, according to the dialysis agent A, in addition to the excellent stability of glucose, it is possible to reduce the acetic acid odor, and furthermore possible to suppress the corrosion of the dialysate delivery system and the dialysis machine.
本发明的目的是提供一种透析剂A,能够将透析液中的总乙酸离子含量设置为低值,具有优异的葡萄糖储存稳定性,能够减少乙酸气味,并能够抑制透析液输送系统和透析机的腐蚀,同时提供一种利用透析剂A的两包装型透析剂。在制备用作两包装型透析剂的一部分的碳酸氢盐透析液中使用的透析剂A中,通过包含葡萄糖,乙酸和乙酸盐,并满足乙酸和乙酸盐的1:0.5到2的摩尔比,以及在所需制备1L碳酸氢盐透析液的透析剂A中包含2mEq或更多但小于6mEq的乙酸和乙酸盐的总量,就可以制备出总乙酸离子浓度在2mEq/L或更高但小于6mEq/L的碳酸氢盐透析液。此外,根据透析剂A,除了具有优异的葡萄糖稳定性外,还可以减少乙酸气味,并进一步抑制透析液输送系统和透析机的腐蚀。
