  • Patent number: 10525078
    Abstract: A solid dialysis A agent is provided, which is to be used in preparing a bicarbonate dialysis fluid, wherein: the solid dialysis A agent contains glucose, acetic acid and an acetate salt; at least a part of a mixture of the acetic acid with the acetate salt is an alkali metal diacetate; and the acetic acid/acetate salt molar ratio is adjusted to 1/0.5 to 1/2. This solid dialysis A agent makes it possible to prepare a bicarbonate dialysis fluid which has a total acetate ion concentration of 2 to less than 6 mEq/L. Further, the dialysis A agent exhibits excellent stability of ingredients and a reduced acetic acid odor.

  • Patent number: 10251988
    Abstract: A dialysis agent A including a mixture containing glucose, acetic acid, and acetate salt, but not sodium bicarbonate, wherein the molar ratio of acetic acid:acetate salt is 1:0.5 to 1:2, and wherein a total amount of the acetic acid and acetate salt contained in the dialysis agent A is between 2 mEq/L and 6 mEq/L when the dialysis agent A is dissolved in 1 L of a bicarbonate dialysate.

  • Patent number: 9931453
    Abstract: 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.

  • Publication number: 20160235785
    Abstract: [Problem] To provide a solid dialysis A agent which is to be used in preparing a bicarbonate dialysis fluid, which enables the setting of a low total acetate ion content in a dialysis fluid, and which exhibits excellent storage stability of glucose or the like and a reduced acetic acid odor. [Solution] A solid dialysis A agent which is to be used in preparing a bicarbonate dialysis fluid, wherein: the solid dialysis A agent contains glucose, acetic acid and an acetate salt; at least a part of a mixture of the acetic acid with the acetate salt is an alkali metal diacetate; and the acetic acid/acetate salt molar ratio is adjusted to 1/0.5 to 1/2. This solid dialysis A agent makes it possible to prepare a bicarbonate dialysis fluid which has a total acetate ion concentration of 2 to less than 6 mEq/L. Further, the dialysis A agent exhibits excellent stability of ingredients and a reduced acetic acid odor.
