WIPO Patent Application WO/2016/042966

Kind Code:

A1

Abstract:

A filter CF1 for filtering dialysis fluid comprises the following: a housing 52 inside of which a filter material 51 is accommodated and which is vertically long; an introduction port 53 that is disposed in the lower part of the housing and that introduces dialysis fluid from an upstream-side flow path 23a; a filtered fluid lead-out port 54 through which filtered dialysis fluid, which has passed through the filter material, is lead out from the upper part of the housing to a downstream-side flow path 23b; and an unfiltered fluid lead-out port 55 through which unfiltered fluid is lead out from the upper part of the housing to a waste fluid flow path 57. When removing the filter from a dialysis fluid circuit 4, fluid is suctioned from the inside of the housing via the upstream-side flow path by using a fluid suction means 64A, and a gas is caused to flow into the housing from the waste fluid flow path and/or the downstream-side flow path by using a gas inflow means 65. The fluid may be suctioned from the downstream-side flow path and the gas may be caused to flow in from the upstream-side flow path, or the fluid may be suctioned from the waste fluid flow path and the gas may be caused to flow in from the downstream-side flow path. Residual fluid in the filter can be reduced.
