<p>Provided is a blood treatment device configured, without impairing the original function of obstruction members, in such a manner that air can easily and quickly flows in the direction of the dialysis solution outlet port of a housing (2) without staying in the space of the housing (2). In a view in the longitudinal direction of the housing (2), obstruction members (11) having a substantially circular cylindrical shape are disposed at the position where a dialysis solution inlet port (7.1) is formed and/or at the position where a dialysis solution outlet port (7.2) is formed. The obstruction members (11) each have an opening (11OP) which is formed in at least one place facing the direction of a side section (S) and which extends in the longitudinal (L) direction. Each of the openings (11O) has a proximal end opening (11OPE) having a smaller width and also has a distal end opening (11ODE) having a larger width. The distal end opening (11ODE) and/or the proximal end opening (11OPE) is configured so that the distal end opening (11ODE) and/or the proximal end opening (11OPE) has rounded sections (R) formed so as to face the directions of both side sections (S), and so that the opening degree of the opening(11OPE, 11ODE) changes gradually.</p> |
