DEVICE FOR SORPTION PURIFICATION OF SPENT DIALYSING Russian patent published in 2017 - IPC A61M1/14 

FIELD: chemistry.

SUBSTANCE: device for sorption purification of spent dialysing or peritoneal solutions contains a hollow body filled with sorbent, two filters for large-dispersed and medium-dispersion filtration and two covers with fittings for connection of mains. The body is horseshoe-shaped with necks having grooves for sealing rings and grooves for securing the covers. Caps are located on the neck and have fastening protrusions for attachment to the neck of the body. The inner cavity of the body is horseshoe shaped, tapering to the throats. Filters are located in the neck of the body. The fittings for connecting the mains are directed in one direction. The outlet cover has a conductivity sensor for monitoring the composition of the cleaned solution, including a connector installed on the outer side of the lid, and stainless-steel contacts connected to it, one made in the form of a ring pasted into the outlet cover and the second in the form of a needle installed in the geometric center of the first contact, by means of a cross provided in the output cover, having a groove for laying the wire connecting the contact to the connector.

EFFECT: increased convenience and safety, increased sorption of metabolites.
