The present invention relates to a phosphate adsorbing agent for blood processing comprising a porous formed article comprising an organic polymer resin and an inorganic ion adsorbent and having the most frequent pore size of 0.08 to 0.70 μm measured with a mercury porosimeter. The present invention also relates to a blood processing system and a blood processing method involving the phosphate adsorbing agent for blood processing.

Phosphate adsorbing agent for blood processing, blood processing system and blood processing method

A blood purification device includes a porous molded body containing an inorganic ion-adsorbing material and is characterized by the following: the concentrations of Mg, Al, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, Rb, Sr, Y, Zr, Mo, Ru, Ag, Cd, Sn, Cs, La, Pr, Sm, Gd, Tb, Ta, Au, Tl, Co, In, and Bi are each 0.1 ppb or less and the concentrations of Ba, Nd, Pb, And Ce are each 1 ppb or less in a physiological saline solution for injection both three months and six months after said physiological saline solution for injection is sealed in the blood purification device; and the number of fine particles having a size of 10 μm or more is 25 or less and the number of fine particles having a size of 25 μm or more is 3 or less in 1 mL of the physiological saline solution for injection.

Blood purification device and method for producing same

Provided is a blood purification device including a porous molded body that has a high phosphorus adsorption capacity and that can be used safely. A blood purification device includes a porous molded body containing an inorganic ion-adsorbing material and is characterized by the following: said blood purification device satisfies the relationship B=&#x2212;0.02 A+2.175&#xb1;0.185 (74&#x2264;A&#x2264;94) when the moisture content of the porous molded body is denoted by A and the bulk density is denoted by B; and the number of fine particles having a size of 10 &#x3bc;m or more is 25 or less and the number of fine particles having a size of 25 &#x3bc;m or more is 3 or less in 1 mL of a physiological saline solution for injection both three months and six months after said physiological saline solution for injection is sealed in the blood purification device.

The present invention provides a phosphate adsorbing agent for blood processing comprising a porous formed article comprising an organic polymer resin and an inorganic ion adsorbent and having a most frequent pore size of 0.08 to 0.70 &#x3bc;m measured with a mercury porosimeter, the phosphate adsorbing agent for blood processing having a biocompatible polymer in the surface of the porous formed article.
