<p>In the prior art, if no packing is used, liquid leaks into the gap between a filter and a liquid port; the use of a packing increases the number of constituent parts of the adsorber and, in addition, if the housing and the ring portion of the filter are small in wall thickness, the packing may potentially be displaced when the housing is welded or otherwise joined to the liquid ports. Furthermore, even if a packing is used, a gap occurs between the filter and an end face of the housing or between the filter and the inner surface of the liquid port and liquid will seep into the gap between the filter and the liquid port. In the case of use as a medical adsorber, a body fluid may leak into the space between the filter and the liquid port and, after the treatment, the body fluid may remain in the clearance between the filter and an end of the housing or between the filter and the inner surface of the liquid port, thus impairing the external appearance of the device. The invention is characterized in that a filling spillage preventing filter having a structure of an elastic soft resin is fixed to the housing as it is pressed between the inner surface of each liquid port and an end face of the housing. <IMAGE></p> |
